Preface: The new generation of PowerCommand Controls will use a new easier to understand naming system. The new controls are modular and therefore it can be confusing to know what feature are being used it the genset control system is only referred to by the control board model. There are several combinations of control boards and HMIs

Naming Chart - PCC 1.X, 2.X, 3.X Naming System

The above naming chart shows the naming system for the new series of controls, PowerCommand Control 1.X, 2.X, and 3.X. The X represents the HMI Operator Panel you have with the series of control board. Here is a list showing how they are structured:

1.X = PCC 1302 control board 2.X = PCC 2300 control board 3.X = PCC 3300 control board Participants’ Guide

Title & Introduction Page6

X.1 = HMI 211 X.2 = HMI 220 X.3 = HMI 320 The PCC 2.X and 3.3 will be released in a couple of different phases. These phases will support certain devices as depicted in the visual above and in more detail throughout this training course. The 2.X, & 3.X series designation will identify the high level of control ability however, there will be several subcategories of different control board features. The first category of 2.X, & 3.3 controls will only work on FAE controlled engines. The next category will be used with hydra mechanical engine applications. As new features and categories develop, additional training courses will also develop. Series 2.X with FAE control training and 3.3 with FAE control training will be the most comprehensive training programs about the PCC 2300 and PCC 3300 controls. The training programs that follow will concentrate on the specific feature enhancements, HMI, or accessory developments relative to the specific Series. The Series 2.X & 3.3 FAE training will be a prerequisite to any future training program It has been planned that the PCC 3300 & HMI320 combination will be the only combination available for the high level paralleling gensets. The plan is to only have a PC 3.3 control and never a PC 3.2 or PC 3.4.

Service Menus

Notes:

• Level 2 = high level adjustments, calibrations, and configurations. • Level 3 = very high level configuration and reserved for engineering or factory access. As an example: • If you access the setup screen for PCCNet Setup, you will not be asked for a password. This is an example of a Level 0 password setup parameter. • If you attempt to access the Adjust Voltage screen, you will be prompted for a Level 1 (574) or higher password. • If you attempt to access the OEM setup parameters, you will be prompted for a Level 2 (1209) or higher password. • The Level 3 password is reserved for engineering and factory configuration and is not shared for field access or setup. If a password is entered, it will remain active until a higher level password is entered or the HMI is INACTIVE for 5 minutes.

Mode Change Password

Mode Change Password Protection If enabled, many of the HMI buttons will be disabled. The operator MUST have the password for them to become operational. 7

Slide 2-7 Mode Change Password

Participant’s Text

Additional Participant’s Text

Look at page 5-1 of 0900-0670 service manual. MODE CHANGE PASSWORD can be confusing to many.

This is a feature to protect a piece of customer equipment, or to protect equipment from the customer. This feature prevents someone from accidentally or unknowingly changing the control from Automatic Mode to Manual Mode or from sending a breaker close command when they shouldn’t. It is to prevent an unauthorized person from making unauthorized changes.

ƒ

MODE refers to the operation mode such as – running in Manual, running in Automatic, Manual parallel, etc... I

ƒ

If Mode Change Password Protection is enabled, the buttons are disabled so an unauthorized operator cannot switch from one mode to another.

If Enabled, any button push on the HMI will prompt a password request screen to appear.

Field technicians may want to use this feature for protection from inadvertent button actuations during service work.

The Password is 121

Slide 2-8 Adjust Screen

Participant’s Text

Notes:

Turn to page 5-30 in the 900-0670 Service Manual Table 5-22 provides a slight description of each ADJUST function. IMPORTANT: Keyswitch Status. The engine must be stopped to activate the Keyswitch Override. The Keyswitch Override is provided to support control service. This setting exists to allow ECM to power down and it will not trigger a “CAN Link Degrade” fault.

Participant’s Text

Additional Participant Text & Notes

What is the purpose of having a Keyswitch override? When servicing an ECM on an automotive application, the ignition key is turned to the on position which provides the input to the ECM to turn on and operate its program. This is the mode you want the ECM to be in during service. On a generator set, we use the E-Stop button as the Keyswitch.

_________________________________ _________________________________ _________________________________ _________________________________ _________________________________ _________________________________ _________________________________ _________________________________ _________________________________ _________________________________ _________________________________ _________________________________ _________________________________ _________________________________ _________________________________ _________________________________

The Keyswitch Override will return to INACTIVE if the E-Stop button is pushed, and/or you will not be able to switch the override to INACTIVE if the local or remote E-Stop is activated. The control must be in the Manual mode to change the override from INACTIVE to ACTIVE. Switching the control from Manual to Automatic while the override is in the ACTIVE state will cause a Data Link Error fault to be generated.

PCC 3.3 & PowerCommand Control 3300 Participant’s Text (OEM GENSET SETUP)

Service Menus Notes:

It is possible to completely configure a new generator control from the HMI, however it is not recommended or you probably do not want to expend the effort. The task of inputting a 10 character genset serial number can take as many as 970 button pushes. The HMI buttons are rated for hundreds of thousands of button pushes, but your finger most likely is not. If you try to input Serial Numbers or Model Numbers, you will find 96 characters available to scroll through, including the entire alphabet in upper case and again in lower case, numerals 0 through 9, 33 symbols and even a blank character.

In the OEM GENSET SETUP, you will find reference to “Input Factory Lock” functions. You will notice there are more than 3 dozen inputs affected by this setup. When the factory configures a genset with all its option, some inputs are consumed and are “Locked”. Factory Lock prevents causal operator changes to the genset setup. Password 1209 is required to change any input from Lock to Unlock or Unlock to Lock. Once unlocked, the input configuration can be changed.

Notes:

There are 2 pages to Engine Setup. This training course will only address some of the FAE application points. Other PC 3.3 control courses will address other engine setup functions. ECM CAN ENABLE turns on the SAE J1939 CAN communications to the engine ECM. Changing the setup to Disable will lead to communication and Operation problems. There may be times when you want to Disable this such as troubleshooting the ECM, but it must be Enabled for genset operation. Fault 1117 Enable is a ECM warning that can be Enabled or Disabled, the setup criteria for this setting will be discussed in more detail several lessons ahead. Prelube Enable is a newer feature option that is available with some engines. There are control provisions to allow for either a rolling Prelube or Prelube pump engagement. Setting this up correctly is dependent on engine and genset configuration. Page 2 offers several setup parameters that should be familiar to technicians.

Service Menus

Notes:

There are 3 pages to Alternator Setup. Like in other OEM SETUP screens, there is a combination of Level 1 and Level 2 password authorized settings. OEM ALTERNATOR SETUP is different from OEM GENSET SETUP. Alternator setup concentrates on voltage regulation performance and on alternator protection setting. Most settings require a Level 2 password. On page 1 you will notice an option for choosing the Excitation Source. You are able to choose between PMG (Permanent Magnet Generator) or SHUNT. Shunt is a term unique to Cummins Power Generation excitation systems and it is synonymous with the industry common term Self Excitation. Scroll through the Alternator Setup pages and you will notice some of the protection settings are very high level protections and these settings if improperly set can contribute to serious damage of the alternator or system. Be VERY CAUTIOUS about sharing the level 2 password with others.

Participant’s Text

Notes:

As with so many things about this control, a different style of thinking is required to understand how this control operates. Modes of Operation: Off Mode On most controls we think of OFF as a condition when no power is being used for any purpose. That is not what this control is doing. In OFF MODE, this control is actively monitoring communications, engine condition, and generator conditions, but it does NOT allowing the engine to run. The control is not operating in Manual nor is it operating in Automatic. The Control is very hard at work making the genset do nothing.

Modes of Operation: Auto Mode Auto Mode operates the same as previous controls. The unit is in a state of readiness awaiting a remote start signal via digital commutations or a remote discrete contact start command. Auto Mode also supports start commands initiated by Exercise and the exercise signal. In Auto Mode when auto start commands are removed, the PCC will enter a shutdown with cooldown sequence. The Exercise Signal can originate from any of these sources. ƒ ModBus signal command. ƒ Operator panel exercise command ƒ Exerciser Schedule.

PCC 3.3 & PowerCommand Control 3300

PowerCommand Control 3300 Sequence of Operation

Manual Start: The PCC3.3 Control System can be place in Manual Run by pressing the Manual button and then the Start button on the HMI320. When the control system is transferring into Manual Run mode the Green LED above the manual button will flash, once the control system has successfully transferred into Manual Run Mode the Green LED will be lit solid. If the Manual button is pressed, but the Start button is not, the control system will not start and the control system will revert back to ‘Off’ after 10 seconds. After the Start button is pressed on the HMI320, the PCC3.3 Control system enters Manual Run mode which begins with the start sequence. The start sequence begins with the engine Pre-Lube Cycle Prelube Cycle Enable if Enabled. After the Pre-Lube cycle is complete, the PCC3.3 control system commands the genset to start cranking by turning on the starter Low-Side Relay driver on Pin J20 -15. At this point, the control system verifies the engine is rotating by monitoring the Average Engine Speed parameter coming from the ECM. If the engine speed is zero after two seconds from engaging the starter the control system turns off the starter, waits two seconds and then re-engages the starter. At this point, if engine speed is still zero the control issues a Fail To Crank (1438) shutdown fault. Once the engine speed is greater then the Start Disconnect speed, the starter is disengaged. For Start Mode = Emergency engine will accelerate to rated speed and voltage and bypass all the idle warm-up delays. At this point, an engine is allowed will warm-up at idle speed until the Idle Warmup Time delay has expired or the engine coolant temperature is greater then the Idle Warmup Coolant Temperature. Upon completing the warm-up sequence, the engine will be commanded to accelerate to rated speed and the genset to rated voltage. Upon reaching rated speed and voltage the ‘Ready To Load’ command will become active. Once the PCC3.3 receives a stop command by placing the control system in Off mode, it will go into cool-down at rated speed if the genset was running with load that is greater than 10% of genset rating. The genset will run in cool-down at rated mode for the Rated Cooldown Time trim setting. The purpose of the cool-down at rated is to cool-down and preserve the engine. After the cool-down at rated is completed the genset will cool-down at Idle speed. After the cool down at Idle speed time expires, the genset is shut down via a normal stop.

For operation of the genset, a short between TB1-15 and TB1-16 must be present. The control enters an emergency stop mode when the short is removed. Before the genset can be restarted, the control must be manually reset by re-applying the short and acknowledging the fault. Local Emergency Stop: For operation of the genset, a short between J25-2 and J25- 6 must be present. The control enters an emergency stop mode when the short is removed.

Participant’s Text

Notes:

Before the genset can be restarted, the control must be manually reset by re-applying the short and acknowledging the fault. It is also required to have physical interruption of the Keyswitch, FSO and Starter relays when emergency stop (either local or remote) is active. In order to achieve this, a second NC switch contact should be added to the Estop switch such that when a Estop button is pressed, this second NC contact is opened. The second NC contact should be wired in series with B+ and the Keyswitch, FSO, and Starter relay coils. Thusly, when the Estop button is pressed, power is removed from the Keyswitch, FSO, and Starter relay coils which in turns de-energizes the relays and prevents further genset operation.

Notes:

Prelube pumps can be controlled by the PCC 3300 control and they can be cycled as desired to maintain an oil coating on the bearing surfaces during times of inactivity. The Prelube relay is optional per genset design requirements. The Prelube pump is optional and types may vary. The relay will engage when the engine is not running, so be aware of unanticipated pump engagement. Prelube will usually be found with larger engines since long & heavy crankshafts and heavy flywheels need to be supported by a sufficient film of oil on bearings.

Notes:

InPower supports the setup functions associated with Prelube. ƒ

Prelube Cycle Enable – turns the Prelube function on or off.

ƒ

Prelube Cycle Time – Sets the amount of time between Prelube cycles. Default 168 hours (7 days)

ƒ

Prelube Oil Pressure Threshold – this as an adjustable setting so that when the predetermined oil pressure is achieved during Prelube Cycle pumping, the cycle will disengage.

ƒ

Prelube Timeout Period – this is an adjustable setting determining how long the Prelube pump should run.

Charging the engine lube system with Prelube keeps internal engine components coated with oil and keeps the oil galleries charged with oil supply. With Cycle Prelube you can set a schedule when the pump will recharge the lube system with pressurized oil. Prelube will also engage at the beginning of an Emergency start command to help charge the lube oils system and bring the system up to safe oil pressure levels as soon as possible. The Prelube cycle is disabled and does not operate while the engine is running.

Notes:

The AUX 103 Power Stage AVR is separate from PCC 3300 main control board to help dissipate the heat being rejected from the AVR circuits. The AUX 103 MUST be mounted with the heat sink fins vertical so convective airflow can help carry heat up and away from the board. Processors on board this module communicate to the rest of the control to optimize Volt/Hz performance and to shut down the AVR output during idle. The AUX 103 also communicates Backup Start Disconnect information.

PWM and Self Excitation The PCC3300 collects main alternator output power at J18 1 & 2 which is genset rated frequency.

The PCC3300 rectifies the incoming phases for a ripple DC power signal.

The PCC 3300 regulates the DC power and then controls the amount of on time for the signal sent back to the exciter field winding. The Pulse duration of DC signal is controlled for the needed excitation rate. Pulse Width Modulation 10

Visual 3-10 PCC 3300 and Self Excitation

Participant’s Text

Notes:

Self Excitation uses 2 phases of power coming off the main output leads of the generator for powering the voltage regulation process. and the voltage could be as low as 100 volts to as high as 240 volts RMS. PWM provides very high performance for voltage regulation response. One of the main shortcomings of a self excited system is the lack of supply power to the excitation system when very heavy loads are applied to the main windings. Motor start performance is not as good with self excitation as you get with PMG power supply.

Visual 3-11 PCC 3300 PMG Excitation

Participant’s Text

Notes:

PMG Excitation offers many advantages over Self Excitation. PMGs are not affected by harmonics or loading on the main windings and can provide a clean source of the needed power to the voltage regulation system as needed when needed. As can be noticed in the above image of the PWM signal, the on time (red) and the off time will vary. If the on time increases, the voltage will increase. The variation of this relationship is called the “% Duty Cycle” on previous controls. Now it is termed AVR PWM Software Command.

Participant’s Text

Notes:

The PCC 3300 provides for multiple forms and options for starter disconnect. The PCC control provides control of the starter control relay, but in FAE applications the ECM is the one who decides when the primary starter disconnect should take place. On FAE applications the EPS (Speed Reference) is determined by the ECM and the information is communicated through CAN to the genset PCC control. If PMG is used, the AUX 103 determines backup start disconnect when PMG voltage achieves 105 volts.

Control Installation Participant’s Text

Notes:

Most technicians will encounter the PCC3300 when it is already installed onto a factory built generator set. However, there will be situations when technicians will need to know about proper installation of the PCC 3300, such as instances when an old/obsolete control needs to be replaced or when troubleshooting, or if adding more features or options.

Adding options in the field will most likely be a common occurrence

Attaching to and utilizing the I/O features will be the most common reason to become familiar with the connectors on this control.

PowerCommand Control 3300 Installation

Notes:

Disable the battery charger FIRST! then disconnect the battery − Negative cable first. Remember to remove the chassis end of the negative battery cable to prevent sparking and possible battery explosions. In class we will power down the simulator to remove power from the control. Remove control-housing cover(s) and connect your wrist strap. Static wrist straps are recommended to prevent static discharge damage to the control boards, but this control may

have up to 600vac bus power connected. For safety reasons, it is best NOT to use a wrist strap, but antistatic handling measures must be employed.

Install the new option or card or other modules, etc. Install the wiring harness for the option. Reconnect battery and enable the battery charger. Remove Lock-out Tag-out. If necessary, use InPower service software to enable the feature(s) or set the required parameters. Test the generator set with the new option to verify proper operation.

Notes:

There are 3 donut style CTs mounted to the board and they are used for monitor of Bus current, not Genset current. These CTs are polarity sensitive and are limited to a maximum of 5 amp passthrough. These CTs are looking for a signal from the bus primary CT mounted in the switchgear bus. Passing the output loop from the bus CT through the center of each CT will induce a signal for the PCC to measure. Make sure each CT is monitoring the proper phase as the voltage sense!

Notes:

PCCNet is a proprietary communication system used on PCC 3300 and several other PowerCommand controls and devices. PCCNet is a low cost communication system developed as a solution for simple networking. A simple network is limited to only 1 generator set control. PCCNet provides functional communication from device to device and it is not for monitoring or building management systems. The ModBus feature is better suited to support this.

PowerCommand Control 3300 PCCNET

PCCNET Communication Operation PCCNet is a Token Passing Network ƒ The authority (Token) to speak (broadcast) passes from device to device on schedule.

ƒ Sequence of this schedule is determined during arbitration (Initializing Communication) at power up.

ƒ Each device knows who is next in line. ƒ The Token holder is the only device allowed to speak. ƒ If there are no communications from a device, and this exceeds 10 seconds, ALL other devices arbitrate again. 4

Visual 6-4 PCCNet Operation

Participant’s Text

Notes:

Broadcast Messages are output messages from a device that has a hard-wired input. Broadcast messages are sent out: • every time the input changes, or • every five seconds. Gensets broadcast NFPA-110 data to the network. Annunciators listen for these messages. Annunciators will also broadcast updates of their hard-wired inputs. The token is passed from device to device in sequence and each device reports its status within the 5 seconds it takes to pass the token throughout the group. If a device is unplugged or if it fails, the rest of the network will notice the absence and will re-negotiate the communication sequence.

Notes:

InPower allows you to configure some of the PCCNet device to launch a fault that will tell you if a device is no longer able to communicate on the network. You have the option to configure a device to ignore a device that is no longer communicating by leaving at the default Non-Critical Device Response, or you can set it to a Critical Device Response. If you have multiple HMI 320s in the system and only 1 fails its communications, the other HMI 320s will display a PCCNet failure alarm. The “PCCNet Device Failure Time Delay” is adjustable from 0 seconds to a maximum of 250 seconds. If the PCCNet system cannot re-establish communication to the device set to Critical Device Response by the end of this set time, a fault will be generated.

Notes:

Troubleshooting PCCNet networks can be easy ---- if you want it to be! As mentioned previously, PCCNet is based on an EIA communication standard referred to as RS485. This standardized industrial protocol has been in use since the 1960s and is well understood in the electronics industry. There are many commercially available testing tools such as protocol analyzers, signal strength & interference testing equipment and media test equipment. If you are experienced with and/or have access to such tools, use them. If you are unfamiliar with such items, there is no need to invest in additional equipment beyond your usual PowerCommand troubleshooting equipment.

PowerCommand Control 3300 PCCNET

Notes:

InPower is an excellent troubleshooting tool when working with PCCNet networks. Use it to check if a device is enabled. The InPower communication system that is used on the PCC 3300 is actually a PCCNet system so if you are able to connect to the HMI or to TB15, then you know PCCNet is operational on those items. The most common and best tool available is your own ingenuity. Here are some suggestions that my help you reason and figure out the cause for a network problem: ƒ

Shut down power to the entire PCCNet Network. When power is restored, each of the devices will try to reestablish communication and “arbitrate”. If one or more of the devices was confused, it may begin working properly after cycling power.

ƒ

Wire problems are the most common failure. Check continuity of each of the comm.. wires and check if B+ and B- is available at each of the modules.

ƒ

If the wires check out ok, try disconnecting the device at the far end of the network. Keep doing this as you work your way back to the PCC 3300, or until the Network begins to work again.

ƒ

Retrieve all the devices in the Network and bring them all close to the 3300 and connect them with very short sections of good wire and see if the system works. Start connecting each device 1 at a time to see if one causes the Network to fail. This technique also helps identify if there are problems with an environment that causes communication problems. This helps identify if the wire is incompatible with the installation, or if EMI noise is present.

Participants’ Guide

Section6 Page16

PCC 3.3 & PowerCommand Control 3300

Participant’s Text ƒ

Check the wire installation throughout the facility. The communication wire should cross power lines/conduits or any AC power in a perpendicular fashion and should never be run parallel to a line carrying AC power.

ƒ

Pay attention to the facility! Look around you.

PowerCommand Control 3300 PCCNET

Notes:

During troubleshooting, it is common for someone to assume the device they know the least about is the problem component. Resist this temptation. Check the things you know the most about and reach a conclusion about a failed component after a process of elimination trial. Sometimes a device will fail, but most importantly, do not ASSUME that the device failed – try to prove it! Look for a reason for it to fail too.

ModBus is an open communication system available onboard the PCC 3300 ModBus was developed in the 1970’s as an industrial protocol to work with Modicon PLCs (Programmable Logic Control) Unlike PCCNet, ModBus does provide functional communication for monitoring or building management systems. The ModBus feature is well suited to support this. All of the content of the ModBus communication messages are predetermined and cannot be changed in the field. (The term message has a very specific meaning in ModBus, so from now on we will call these packets of info Registers.)

ModBus Overview ƒ CPG uses ModBus over Serial Line Protocol. ƒ ModBus Serial Line protocol is a Master - Slave protocol. ƒ A Master-slave type system can have only one master node and multiple ƒ ƒ ƒ ƒ ƒ

slave nodes. The PC1.X, 2.X & 3.3 controls are a Slave Node. A bus can accommodate 32 devices without repeaters, but up to a maximum of 247 slave nodes can exist on a large ModBus network bus. ModBus can communicate using many different physical media. The PCC 1302 uses EIA-485 (RS485) two-wire (2 wire) interface. ModBus can use two different serial transmission modes: RTU mode or ASCII mode. All ModBus transmissions are verified for CRC errors.

Notes:

The PCC 3300 ModBus port is a serial port. It follows EIA standards and is configured for rs485: ModBus is comprised of multiple different transmission modes. The most common modes encountered on CPG systems are: RTU. (modern & most common) ASCII (considered old & rare and is not used on the PCC 3300) ModBus is a Master – Slave communication system ƒ ƒ

Section 7 Page5

PCC 3.3 & PowerCommand Control 3300

Participant’s Text

PowerCommand Control 3300 ModBus

Notes:

In a master – slave system, the master device requests data from a particular slave device. This is called a poll. The register sent back from the slave device is called a response. The slave device does not send any data unless it is polled by the master. If the master device sends a command such as a engine start command the slave device will still send back a response acknowledging that it received the command register (poll) Many communication systems use a CRC error checking scheme. ModBus does too, and it is highly effective. CRC stands for Cyclical Redundancy Check, which is a way of checking if a message is corrupted or damaged during its transmission. Sometimes this check is called a Check Sum. CRC errors do NOT indicate that a device is having trouble or is faulty; it indicates that the register created by the device is good at origination, but it is corrupt at the destination. Serial communication systems are very susceptible to electro-magnetic interference and other electronic noise, so it is not considered the best choice for installation into a power generation environment. Therefore the CRC error checking feature built into ModBus is very important. The PCC 3300 is not able to warn you of CRC errors, but the master device in the system will. Since the master device is usually the responsibility of a 3rd party, you will need to work with them to identify and resolve the problem.

Notes:

Remember the previous statement about serial communications being susceptible to EMI and other noise. The type of communication cable used can affect communication reliability too. Designers of Building Management Systems (BMS) usually have a specification for the cable used in their system. It is rare that CPG installing technicians will be requested to supply the ModBus communication cable. If installing an iWatch to monitor a PCC 3300, try to keep the ModBus cable as short as possible or practical. Details of the installation will be found in the iWatch installation guide.

Recall that a ModBus network may contain up to 247 nodes. The node address identifies to the ModBus Master which of those 247 devices is the PCC 3300. The ModBus Baud Rate adjusts the speed of communication that the PCC 3300 must be set at to communicate in the Network. The ModBus Parity setting changes the register structure per the requirements of the network design. The default is Even. The Parity adjustment for TB15 can be set differently than the Parity adjustment for J14. ModBus Failure Time Delay can trigger fault 2939 – ModBus Failure if the Master response time exceeds the set amount of time. The ModBus Communications Lost Response Method can be set to reset in case there is a loss of communication. The ModBus settings are usually requested by the network installer. The Failure Time Delay and Lost Response Method settings are usually chosen by the CPG installer.

InPower Of course, it is not possible to monitor a communicating ModBus network with InPower since the TB-15 port is used for ModBus communication and for connection to InPower. The data displayed in the Monitor screens is recorded data. ƒ ƒ ƒ ƒ ƒ

Bus Message Count – this is the number of times that the PCC 3300 has been polled by the Master. Slave Message Count – this is the number of times the PCC 3300 has responded to polls. No Response Count – this is the number of times the PCC 3300 HAS NOT been able to respond. CRC Error Count – this is the number of times the network has seen a faulty register. Exception Count – this is the number of times the system has seen a corrected version of a faulty register.

CRC errors are encountered when a register is sent correctly, but the receiving device views it and finds errors in it. The receiving device will automatically request that the register be sent again. This error count is very valuable to you if you are troubleshooting ModBus communications. It indicates that the devices are trying to send or receive messages, but someplace along the transmission stream, the register is being damaged. Start inspecting the wiring and connections. The problem could be caused by poor quality or inadequate wire, poor connections, or environmental issues such as electromagnetic interference.

ModScan is not a Cummins product. It is available as freeware from WinTech via Web download or through several other free sources. The free version limits connection time to an active ModBus network to 3 minutes, and then it stops polling. A code to enable unlimited connection time is available for purchase from WinTech. CPG encourages the use of ModScan as a testing tool to prove to customers and integrators that the ModBus port is communicating properly. There are other software products that can be used too, but ModScan is considered a simple to use.

PowerCommand Control 3300 ModBus

Notes:

ModScan Software. Once connected, ModScan will poll registers and will allow write registers. Write registers will send a command to the generator set. A common command is to START the genset. The genset must be in Auto for the command to take effect. It is a simple process to configure ModScan to communicate with PCC 3300, but if you need assistance with proper setup and operation, refer to the details found in Appendix B The standard InPower communication cable from the computer com port to the PCC 3300 TB-15 port can be used. The RS232/RS485 converter must be used too. Refer to the ModBus register map to help you identify the register that you may wish to poll. The 2 most common register types to check are: 1. Coil Status – this is an on/off statue indication. 1=ON & 0=OFF 2. Holding Register – this indicates a message indicating up to 16 bits of information. Example in visual 7-9 shows register #40016. It will appear {0000000000000000} A common test is to “Write” bit “1” to register 40300, the genset should start if the control is in automatic mode. (Remote) Register 40302 can activate the Emergency Stop. If this is activated via ModBus, you cannot reset the shutdown at the genset control until the ModBus command is set to 0.

Wrap-Up In this lesson we have learned about the ModBus communication system and the ModBus feature built into the PCC 3300. First we talked about the basics of ModBus communications and some of the specific information about how the system works. Next we talked about ModBus connection requirement on the PCC 3300, its connectors and wire information. Next we talked about the setup and configuration using InPower and the HMI320 setup. Then we talked about the testing and troubleshooting. This was separated into 3 separate areas that required additional information. Lastly we went through each of the testing and troubleshooting tools and information available to technicians. This lesson gave us the opportunity to learn some basics of ModBus and a little about this communication feature on the PCC 3300. This section is a basic introduction to ModBus communications with PCC control and communication systems. We will continue delving deeper into ModBus communications with more advanced controls. This section serves as a prerequisite for training on some of the more advanced PCC controls Q. Are there any questions we have not yet covered on ModBus for the PCC 3300?

In order to view/change parameters and perform certain tests, technicians will need InPower, INSITE, and Inline software/hardware/drivers in order to connect to the engine ECM and PCC 3300 control. An easy and cost effective way to view signals and perform simple troubleshooting tasks is to use the Peak System Adapter. While the Peak Sys Adapter does not allow you to perform calibrations, it is an easy tool to operate and see if the system ECM and PCC are communicating properly.

Notes:

You can purchase the Peak Adapter from the Cummins Hardware Shelf or from www.gridconnect.com/usbcanin.html Not only will you need to order the adapter itself, but you will need to buy an inline CAN terminator. You will also need a CAN cable that allows you to connect from the 9-pin plug on your Peak System Adapter to the 3-pin Deutsch connector on the genset. After you have all of the required hardware, you will need to download the software and associated drivers. Drivers to operate the Peak System Adapter can be ordered from the Cummins Software Shelf. You will need to order these software tools: •

Peak All In One Driver



PCAN Explorer (optional)

Once you have the hardware and software installed, you can connect to a device and read the messages. The software will have a default baud rate of 500Kbit/sec. This needs to be changed to 250Kbit/sec in order to communicate with the PGI system. You do not need the engine running to see messages transmitted on the system. Once you have the Peak System Adapter setup properly you will be able to connect and read the messages sent. This tool provides an easy way to help determine whether the ECM (s), PCC, or backbone is faulty.

The first portion of PGI we will cover is the PHYSICAL datalink. There are three main parts of the physical datalink: Backbone, Plugs, and Stubs. The Backbone consists of a three-wire system that has a high, low and a shield wire. In visual 8-5 above you can see the pinout of this system. There are two different types of Plugs that are used on this system. The first is the plug that has orange keys inserted into the Deutsch connector. The second is a termination plug. This is verified by a blue key and is capped with a 120ohm resistor receptacle.

The total length of the backbone is not to exceed 40m (approx 131 ft) in length. This is a J1939 SAE standard requirement. The Stubs are depicted in Visual 8-6. These stubs need to be kept to 1m (approx 3 ft) in length. There are a maximum of 30 different devices that can be installed on the backbone at once. To minimize message reflections (echo) on the data link, a 120ohm terminating resistor is needed at each end of the backbone.

Participant’s Text

Notes:

This is a simple chart to follow in order to check the physical datalink. If you are having communication errors these are good points to start with the troubleshooting process. ƒ

Keyswitch should be cycled every time there is an engine shutdown in order to save important ECM data (Ex: fault codes, ECM run time etc.). Wait 30 secs or more before engine restart.

ƒ

There are NO Fault Acknowledge inputs to the ECM to reset active faults. The ECM will broadcast an active fault as long as the condition is true.

Participants’ Guide

Section 8 Page 17

PCC 3.3 & PowerCommand Control 3300

Participant’s Text ƒ

You can remove one terminating resistor and you should be able to see the other resistor of 120 ohms. You can replace that terminating resistor and remove the other one to check for 120 ohms on that resistor.

ƒ

While both terminating resistors are installed, remove J11 from base board. Check resistance between J11-19 and J1120. Resistance should be approximately 60 ohms if the backbone is ok. If you have less than 55 or more than 65 ohms there is a potential problem with an open or ground on the datalink.

PGI

Notes:

Here are some rules to apply for an open or shorted CAN circuit. CAN_H is Shorted to VBat - Data communication is not possible if VBat is greater than the maximum allowed common mode bus voltage. CAN_L is Shorted to GND - Data communication is possible, because the bus voltages are within the allowed common mode voltage range. Signal-tonoise ratio is reduced and radiation is increased. The electromagnetic immunity is decreased. CAN_H is Shorted to GND - Data communication is not possible. CAN_L is Shorted to VBat - Data communication is not possible. CAN_H is Shorted to CAN_L - Data communication is not possible. Loss of Termination Resistor - Data communication via the bus may be possible, but with reduced signal-to-noise ratio.

essential that all devices are on the same ground plain. – If the grounds of two ECM’s are different, then a low voltage differential of one ECM may appear to be a high voltage differential to another. Hence messages get corrupted and communication is lost.

Participant’s Text

Notes:

The properties of the J1939 datalink message are broken down into bits. A “bit” takes, at most, 0.0000002secs to travel down a 40m datalink. And an entire message (110bits) takes 0.00044secs to be transmitted. That’s a possible 2000 messages per second. If two devices attempt to broadcast at the same time, the message with the highest priority wins and the other device “waits”.

Participant’s Text

Notes:

The Power Command 3.3 control provides paralleling functionality for several modes of parallel operation. Parallel operation is not a new or unique feature. It has been offered with many of the predecessors to the PCC3300, however: this control provides any desired mode of paralleling operation as standard. The control is fully configurable in the field AT WILL. You no longer have to contact the factory and purchase new codes or added features. They are all here.

Participant’s Text

Notes:

Standalone: Standalone mode is more like a non paralleling control configuration. There are a couple of added features that make this configuration more desirable than just using a PC2.X control. Synchronization: This is a mode designed to allow the genset to match frequency and voltage with another source. In some modes of this operation the PCC does not control connection to the source and in some modes the PCC is in full control of all connection functions.

Paralleling Introduction

Notes:

Sync. Cont: Synchronization is utilized in all the different paralleling modes beyond the Standalone mode. Droop: Droop is an adjustable feature that can be turned on as the application requires. The unit is able to operate in speed droop, and/or voltage droop. Load Share: In Load Share, the PCC is in parallel with other gensets while isolated from the utility. The PCC adjusts the speed reference and the voltage set point so that the genset takes its fair share of the load. The genset should run at the same percentage of its rated load at which other gensets run. Load Govern: In Load Govern, the PCC is in parallel with the utility. Since the utility frequency and voltage are fixed, the PCC regulates the genset kW output and genset kVAR output, instead of the genset frequency and genset voltage. Power Transfer Control: Power Transfer Control (PTC) is a feature that will be available during the Phase 2 launch. This feature allows the PCC to act as the transferswitch control in addition to acting as the genset control.

Is Standalone Paralleling? ƒ Standalone is a mode that does not parallel, it does not synchronize with any other genset or system.

ƒ In Standalone the PCC does not control a breaker for connection or disconnect from load, but can provide a breaker trip signal, and it can monitor breaker position. kW Demanded by Load kVar Demanded by Load

ƒ In Standalone mode operation, a single generator set is connected to a bus in order to provide power to a common load. 2

Visual 10-2 What is Standalone paralleling.

Participant’s Text

Notes:

Standalone is a mode of operation that allows the generator set to be used in a single power supply situation and still provide some added feature for monitoring and protecting the genset AND the installation. In Standalone mode the power capacity of the power system is regulated by the capacity of the single generator set and it alone is responsible for maintaining voltage and frequency. In paralleling systems, all of the units in the system contribute and share this function.

Synchronizer Only Mode

Notes:

The frequency/phase matching control provides for two methods of automatic frequency synchronizing. The first is Phase Match which will attempt to drive the phase error to zero. A phase offset adjustment is included for cases where a phase shift exists due to a delta / wye transformer for example. The second method of synchronizing is Slip Frequency which will attempt to drive a fixed frequency difference between the two sources. In some cases this is used to insure that power will flow in the desired direction at the initial time the sources are paralleled, or with a genset whose governing cannot be accurately enough controlled to phase match (such as gas gensets). The control provides one method of automatic voltage synchronizing which is voltage match. This method will attempt to drive the voltage error to zero. In most cases synchronizing is automatically initiated by the control when necessary. This is done by connecting sync enable/configurable input #30 on TB10 to a return.

Notes:

All units operate at the same frequency (speed) and voltage. Generally speaking, the units can operate in various modes which will determine how individual units will react to load conditions, but all units will work together on line to share the load. Droop and Isochronous modes are available. , The bus system may consist of switchgear with bus work or it may consist of cable connections between gensets and breakers.

Participant’s Text Dead Bus Close & First Start Arbitration: First start arbitration is used in a multi-genset system to control which genset gets to close to a dead bus. Only one genset is allowed to close to a dead bus. All others must synchronize. The genset controls arbitrate with each other through an interconnected first start signal. Once a genset has reached the ready to load state and the bus is sensed as being dead, it can join in the arbitration. When the arbitration completes, one genset has "won" permission to close and will be allowed to command its breaker to close. At the same time this genset puts the interconnected arbitration signal into an inhibit state which tells all other gensets that they do not have permission to close. Once the permitted genset has closed to the dead bus, then the other gensets will see the genset bus go live and begin synchronizing to it. If a genset has been waiting to win permission to close to a dead bus and it has not received that permission within a set amount of time, it will assume that the first start system has failed and will close its breaker to the dead bus. This is the First Start Backup function. This prevents a situation where no genset closes to the bus due to a failed first start system.

Participants’ Guide

Section 12 Page5

PCC 3.3 & PowerCommand Control 3300

Isolated Bus Mode

WARNING! --- This does present a risk of multiple gensets closing to the dead bus, but this risk is reduced by setting the first start backup time delays to be significantly different on each genset. E.G. 10 sec, 20sec, 30 sec, etc. Then the assumption is that all gensets were started at the same time.

Synchronizing: The frequency/phase matching control provides for two methods of automatic frequency synchronizing. The first is Phase Match which will attempt to drive the phase error to zero. A phase offset adjustment is included for cases where a phase shift exists due to a delta / wye transformer for example. The second method of synchronizing is Slip Frequency which will attempt to drive a fixed frequency difference between the two sources. In some cases this is used to insure that power will flow in the desired direction at the initial time the sources are paralleled, or with a genset whose governing cannot be accurately enough controlled to phase match (such as gas gensets). The control provides one method of automatic voltage synchronizing which is voltage match. This method will attempt to drive the voltage error to zero. In most cases synchronizing is automatically initiated by the control when necessary. This is done by connecting sync enable/configurable input #30 to a return. Load Share: The load share function manages the genset’s kW and kVAR production when it is connected to a common bus with other gensets while isolated from the utility bus. Each genset must determine how much of the total bus load to take. The desired result is for each genset to take its equal share of the load relative to its own rating while maintaining the bus frequency and voltage at the nominal values. (i.e. Each would end up taking the same % load.) The sharing of kW is controlled by fuel (speed). The sharing of kVAR is controlled by excitation (voltage). Isochronous In order to share load while maintaining fixed frequency and voltage, some form of communication between the gensets must occur. (The other option with no communication is speed and voltage droop.) This is accomplished via the “load share lines”. There is a pair for kW and a pair for kVAR. Controller compatibility for Paralleling must b considered. When a paralleling system consists of different models of PCC3XXX genset controls, some adjustments are necessary in order to insure comparable load sharing performance. These adjustments are NOT necessary if the controls are all identical control models. What are the symptoms or issues if these adjustments are not made or are made improperly? 1. Reverse kVAR (Loss of Field) shutdowns may occur. 2. Bus Voltage may shift from nominal. (I.E. It may look like voltage droop.) 3. With the control default kVAR balance settings, the kVAR sharing will not be balanced.

Participants’ Guide

Section 12 Page6

PCC 3.3 & PowerCommand Control 3300

Isolated Bus Mode

4. Even after balancing the kVAR sharing at one kVAR load condition, the kVAR sharing may not be balanced at a different kVAR load. 5. kVAR sharing will not be equal when V/Hz is acting (e.g. during a large kW transient or overload condition). 6. Reverse kW or Reverse kVAR shutdowns may occur during Master Synchronizing with MCM3320 Droop Droop is a passive means of having paralleled gensets share kW (via speed droop) and kVAR (via voltage droop). In the case of speed droop, as kW load increases, speed (i.e. fueling) is reduced, forcing other gensets to pick up more kW thus resulting in a balance. In the case of voltage droop, as lagging kVAR increases, voltage (i.e. excitation) is reduced, forcing other gensets to pick up more lagging kVAR thus resulting in a balance. Droop can be used on an isolated bus for passive sharing among gensets. All gensets may be operated in droop, but this leads to a frequency which changes with load. Another alternative is to operate one of the sets as a “lead” unit in the isochronous mode. The other sets operating in droop will be forced to go to the isochronous speed and thus they will be effectively base-loaded. The lead unit then takes up all the changes in load that occur while maintaining a fixed frequency bus. As an example, if the genset set to operate in isochronous mode at a frequency of 57Hz were run in parallel with a genset operating in droop set as shown in Figure 1 with a nominal frequency of 60Hz the genset in droop would be loaded at 50% kW. If it were desired to run both gensets at 60Hz and still load the genset operating in droop to 50% set the Frequency Adjust trim on the genset operating in droop to 3 to increase the 0% kW output frequency to 63Hz. Figure 1 Load Share – Droop kW is a graphical representation of speed droop. In this case the Speed Droop Percentage trim has been set to 10%. As can be seen from the graph at 100% kW ouput the genset will be operating at 90% of nominal frequency. In other words for a nominal frequency of 60Hz the genset will be running at 54Hz at full load. Figure 2 Load Share – Droop kVAR is a graphical representation of voltage droop. In this case the Voltage Droop Percentage trim has been set to 5%. As can be seen from the graph at 100% kVAR ouput the genset will be operating at 95% of nominal voltage. In other words, for a nominal voltage of 480VAC the genset will be running at 456VAC at full load.

If the CTs wires are installed backwards, the control will sense a phase shift and the control may not parallel correctly or there will be erroneous readings of load or PF. Most Switchgear manufacturers build their gear with CT shorting blocks in place. It is the responsibility of the installation designer to make certain there are shorting blocks in the system.

TB5 provides the hookup points to control breaker open and another for breaker close control. Breaker motors can consume a large amount of energy during actuation. The power consumption is so great that damage to PCC control can take place if you attempt to drive the breaker directly from this connector. Use a pilot relay of sufficient size to run the breaker, but be aware that relay motors can sometimes consume a large amount of energy. Make sure the relay motor does not exceed the specification listed on this visual.

SECTION 14 -- Glossary AC

Alternating Current (AC) is electric current that alternates between a positive maximum value and a negative maximum value at a characteristic frequency, usually 50 or 60 cycles per second (Hertz).

Alarm

Used generically to indicate either a warning or a shutdown fault.

ANSI

American National Standards Institute.

Acoustic Material Acoustic material is any material considered in terms of its acoustic properties, especially its properties of absorbing or deadening sound.

Active Power Active power is the real power (kW) supplied by the generator set to the electrical load. Active power creates a load on the generator set's engine and is limited by the horsepower of the engine. Active power does the work of heating, turning motor shafts, etc.

Air Circuit Breaker An air circuit breaker automatically interrupts the current flowing through it when the current exceeds the trip rating of the breaker. Air is the medium of electrical insulation between electrically live parts and grounded (earthed) metal parts.

Alternator Alternator is another term for AC generator.

Alternator Rating Effect

Some of the alternator protections are inherently related to the alternator capabilities rather than GenSet power rating. For example, Reverse VARs (Loss of Field), is inherently a function of alternator capability. Overcurrent is inherently a function of alternator capability. If data to an alternator’s capability in these areas is not available, the PowerCommand Control will default to basing the limits on the on the GenSet rating — as the previous version of the PowerCommand Control did. (GenSet rating is either engine limited or alternator limited — normally engine limited.)

Training Guide

Section 14 Page1

PCC 3.3 and PowerCommand Control 3300

PowerCommand Control 3300 Glossary

Amortisseur Windings

The amortisseur windings of a synchronous AC generator are the conductors embedded in the pole faces of the rotor. They are connected together at both ends of the poles by end rings or end plates. Their function is to dampen waveform distortion during load changes.

Ampacity

Ampacity is the safe current-carrying capacity of an electrical conductor in amperes as defined by code.

Ampere

The ampere is a unit of electric current flow. One ampere of current will flow when a potential of one volt is applied across a resistance of one ohm.

Annunciator

An annunciator is an accessory device used to give remote indication of the status of an operating component in a system. Annunciators are typically used in applications where the equipment monitored is not located in a portion of the facility that is normally attended. The NFPA has specific requirements for remote annunciators used in some applications, such as hospitals.

Apparent Power

Apparent power is the product of current and voltage, expressed as kVA. It is real power (kW) divided by the power factor (PF).

Armature The armature of an AC generator is the assembly of windings and metal core laminations in which the output voltage is induced. It is the stationary part (stator) in a revolving-field generator.

Authority Having Jurisdiction

The authority having jurisdiction is the individual with the legal responsibility for inspecting a facility and approving the equipment in the facility as meeting applicable codes and standards.

Automatic (Exciter) Paralleling Automatic (Exciter) Paralleling describes a system where two or more generator sets can be started and paralleled while coming up to rated frequency and voltage. Because the generator excitation system is not turned on until the generator set is started (thus the term "dead field"), the generator sets automatically synchronize as they come to rated speed and voltage.

B+ Return Similar to battery negative (B-). This may be an isolated battery negative circuit and may not be directly connected to chassis ground or the battery negative. In some circumstances it may float at a different potential than chassis ground.

Bus Bars

Bus Bars are rectangular copper or aluminum bars that connect the output of the generator set circuit breakers to the transfer switches, circuit breakers, or fusible switches that transfer power to the load. The bus bars are sized and assembled in multiples according to the current they must carry under load. A typical sizing criteria for copper bus bars rated from 500-5,000 amps is to maintain a current density of 1,000 amps per square inch of cross-sectional area. This results in a bus temperature rise at full load that is within acceptable limits.

Cross currents are currents that circulate between paralleled generator sets when the internal (excitation) voltage of one genset is different from the other genset(s). The genset with the higher internal voltage supplies reactive power (kVAR) to the other genset(s). The amount of cross current that flows is a measure of this reactive power. Cross currents are 90 degrees out of phase (lagging) compared to the current that the generator would supply at 1.0 (unity) power factor.

kVAR is the product of the voltage and the amperage required to excite inductive circuits. It is associated with the reactive power which flows between paralleled generator windings and between generators and load windings that supply the magnetizing currents necessary in the operation of transformers, motors and other electromagnetic loads. Reactive power does not load the generator set's engine but does limit the generator thermally.

Local Loop

A method of branching out or creating a stub on the network. The maximum distance this stub can be is 10ft. (3m) from the main network bus. Effectively the node is "daisy-chained" into the network. This involves two wires, one that goes to the node and another that returns to the main network bus. The total local loop distance must be added to the total network length. This becomes important when the main network bus nears the 4,600 ft. length and requires the use of Routers.

Molded case circuit breakers usually contain thermal-magnetic trip units, although larger sizes can be equipped with solid state trip sensors.

Motoring In paralleling applications, unless a generator set is disconnected from the bus when its engine fails (usually as a result of a fuel system problem), the generator will drive (motor) the engine, drawing power from the bus. Reverse power protection which automatically disconnects a failed set from the bus is essential for paralleling systems. Also, in certain applications such as elevators, the load can motor the generator set if insufficient additional load is present.

The overload rating of a device is the load in excess of the nominal rating the device can carry for a specified length of time without being damaged.

Overshoot Overshoot refers to the amount by which voltage or frequency exceeds the nominal value as the voltage regulator or governor responds to changes in load.

Parallel Operation

Parallel Operation is the operation of two or more sources of AC electrical power whose output leads are connected to a common load. Connection of the power sources is made so that the sources electrically function as a single source of power. Parallel Operation requires that the two sources of electrical power must match in voltage, frequency, and number of phases.

A paralleling breaker is the circuit breaker that connects the generator set to the emergency bus, and across which all the individual generator synchronizing functions occur.

Paralleling Control A paralleling control contains the electrical equipment provided in a paralleling system for control of a single generator set.

Paralleling Suppressers

Paralleling suppressors are semiconductor devices that protect the silicon diodes on a brushless excitation system from damaging overvoltages. Overvoltages, usually of short duration, occur when a generator is paralleled out of phase with the energized bus.

PowerCommand Control 3300 Glossary

Peer-To-Peer

A network operating system where any device on the main network bus can initiate communication.

Phase Phase refers to the windings of an AC generator. In a three-phase generator there are three windings, typically designated as A-B-C, R-S-T or U-V-W. The phases are 120 degrees out of phase with each other. That is, the instants at which the three phase voltages pass through zero or reach their maximums are 120 degrees apart, where one complete cycle is considered 360 degrees. A single-phase generator has only one winding.

Phase Angle

Phase angle refers to the relation between two sine waves which do not pass through zero at the same time. Considering one full cycle to be 360 degrees, the phase angle expresses how far apart the two waves are in relation to each other in degrees.

Phase Rotation Phase rotation (or phase sequence) describes the order (A-B-C, R-S-T, or U-V-W) of the phase voltages at the output terminals of a three-phase generator. The generator phase rotation must match the facility phase rotation. This must be checked prior to operation of the electrical loads in a facility with an on-site generator.

PGI CAN Acronym for Power Generation Interface to Cummins J1939 CAN communication systems.

Pilot Relay

A Pilot Relay is a simple relay which uses a low current coil that activates high current contacts. The PCC 1302 control board has limited output power and it can be damage if it is connected directly to high power DC loads such as fuel shut off solenoids or starter solenoids.

Pitch

Pitch is a mechanical design characteristic of a generator that indicates the ratio of the number of winding slots per generator pole to the number of slots enclosed by each coil. The generator designer may use the pitch of a machine to optimize the generator cost versus the quality of the voltage waveform generated.

Pole

Pole is used in reference to magnets, which are bipolar. The poles of a magnet are designated North and South. Because magnets are bipolar, all generators have an even number of poles. The number of poles determines how fast the generator will have to be turned to obtain the specified frequency . For example, a generator with a 4-pole field would have to be run at 1800 rpm to obtain a frequency of 60 Hz (1500 rpm for 50 Hz). Pole can also refer to the electrodes of a battery or to the number of phases served by a switch or breaker.

The smaller kW range sets commonly have non-Cummins engines. The PCC 1302 control operates on 12 Volt or 24 Volt battery systems. It can be used without extra componentry on gaseous fuel gensets. When used on some Diesel gensets, an external governor signal amplifier is needed. The PCC 1302 is intended to be available for use on all non-paralleling Cummins gensets up to 1,500 kW in 2008.

PowerCommand Network A communication network for moving information electrically among various Onan on-site power generation modules. The PowerCommand Network will utilize Echelon LonWorks for system module interconnection.

Power Factor

Power factor is the cosine of the angle between the active power (kW) and apparent power (kVA) in a circuit.

Prime Power

Prime Power describes an application where the generator set(s) must supply power on a continuous basis and for long periods of time between shutdowns. No utility service is present in typical prime power applications.

Priority Control

Priority control is the process by which the total loads on the bus is limited to the most critical loads in the system until adequate generation capacity is available to serve all loads.

Protocol

Radio Interference Suppression

Radio interference suppression refers to the methods employed to minimize radio interference.

Random Access Paralleling

Random access paralleling is a paralleling operation where any generator may be the first unit to close to the bus on startup of the system. Random access systems use active synchronizing to force the second and all subsequent generator sets to close to the bus as fast as possible.

Rated Current To be calculated based on rated power (kW) and nominal voltage.

Rated kW

Definition #1: This is set by the end application — standby, limited time prime, unlimited time prime, or continuous. Definition #2: Determined by the rated current and voltage programmed into the Base card by the Manufacturing Tool or calibration downloaded by InPower software. This is the maximum kilowatt load the generator set can provide.

Reference Value

A value in a control loop which determines to what value the control loop is attempting to drive the output. An example situation would be when a synchronizing control loop is attempting to drive the genset frequency to match the bus frequency. Perhaps the genset nominal frequency is 60.0 Hz, the genset set point frequency is 61.5 Hz, but the bus frequency is 59.0 Hz because it is overloaded. Prior to closing the circuit breaker, the genset will set its reference frequency to 59.0 to allow it to match the bus. At this time, the reference value is 59.0 Hz.

Reactance

Reactance is the opposition to the flow of current in AC circuits caused by inductances and capacitances. It is expressed in terms of ohms and its symbol is X.

Reactive Differential Compensation Reactive differential compensation (also called cross current compensation)is a method of controlling the reactive power supplied by generators in a paralleling system so that they equally share the total reactive load on the bus, without inducing significant voltage droop in the system.

Reactive Droop Compensation

Reactive droop compensation is one method used in paralleled generator sets to enable them to share reactive power supplied to a load. This system causes a drop in the internal voltage of a set when reactive currents flow from that generator. Typically, at full load, 0.8 PF, the output voltage of a set is reduced by 4% from that at no load when reactive droop compensation is used.

Reactive Power

Reactive power is power that flows back and forth between the inductive windings of the generator and the inductive windings of motors, transformers, etc., which are part of the electrical load. This power does no useful work in the electrical load nor does it present load to the engine. It does apply load to the generator and limits the capacity of the generator.

Reactor

A reactor is an electrical device that applies only reactive load to a system.

Real Power Real power is the product of current, voltage and power factor (the cosine of the angle by which current leads or lags voltage) and is expressed as W (watts).

Resistance

Resistance is the opposition to the flow of current in DC and AC circuits. It is expressed in ohms and its symbol is R.

Reverse Power Relay

A reverse power relay is a relay with a wattmeter movement that senses the direction of power flow. In paralleled sets, a flow of reverse power (i.e., power flow into set) will actuate the reverse power relay and disconnect the set from the system. If one set stops and reverse power protection is not provided, the set still running will drive the set that has stopped. The generator on the set that has stopped will act as a motor.

Risers

Risers are rectangular copper or aluminum bars that connect circuit breakers, fusible switches, and transfer switches with the main system bus. As with bus bars, they are sized and assembled in multiples according to the current they must carry.

Sound

Sound is considered both in terms of the sound pressure waves travelling in air (pressures superimposed on the atmospheric pressure) and the corresponding aural sensation. Sound can be "structure-borne", that is, transmitted through any solid elastic medium, but is audible only at points where the solid medium "radiates" the pressure waves into the air.

Sound Level Meter

A sound level meter measures sound pressure level. It has several frequency-weighted decibel (dB) scales (A, B, C) to cover different portions of the range of measured loudness. Sound level meters indicate RMS sound, unless the measurements are qualified as instantaneous or peak sound level.

Sound Pressure Level (SPL)

Sound pressure level is a measurement of the pressure fluctuations of a sound wave as it propagates through the air. Because of the wide range of pressures to which the ear responds, a logarithmic scale is used and is expressed as a ratio of the measured pressure referenced to a pressure of 2x10-5 N/m2 (20 m Pa) which is the threshold of human hearing at 1000 Hz. The measure is expressed in decibels (dB). The Bel unit is named after Alexander Graham Bell.

Standby System

A standby system is an independent power system that allows operation of a facility in the event of normal power failure.

Starting Current

The initial value of current drawn by a motor when it is started from standstill.

Stator

The stator is the stationary part of a generator or motor. See Armature.

Sync Check Relay A sync check relay is an electrical device that monitors the phase relationship between two voltage sources and provides a signal when the voltage sources are within specific preset parameters.

Synchronization

In a paralleling application, synchronization is obtained when an incoming generator set is matched with and in step to the same frequency, voltage, and phase sequence as the operating power source.

Synchronizer

A synchronizer is an electronic device that monitors the phase relationship between two voltage sources and provides a connection signal to an engine governor, to force the generator set to synchronize to the system bus.

Synchronizing Lights

Synchronizing lights are lamps connected across the line contactor of the incoming generator set. The lights indicate when the voltage waveforms of the incoming and operating power sources coincide and paralleling can be completed.

Synchronous Generator A synchronous generator is an AC generator having a DC exciter. Synchronous generators are used as stand-alone generators for emergency power and can also be paralleled with other synchronous generators and the utility system.

PowerCommand Control 3300 Glossary

Synchroscope

A synchroscope is a meter that indicates the relative phase angle between an incoming set voltage and the bus voltage. The synchroscope pointer indicates whether the set is faster or slower than the bus and allows the operator to adjust the frequency (speed) accordingly before manually paralleling to the bus.

Telephone Influence Factor (TIF)

The higher harmonics in the voltage wave shape of a generator can cause undesirable effects on telephone communications when power lines parallel telephone lines. The telephone influence factor is calculated by squaring the weighted RMS values of the fundamental and the non-triple series of harmonics, adding them together and then taking the square root of the sum. The ratio of this value to the RMS value of the no-load voltage wave is called the Balanced TIF. The ratio of this value to three times the RMS value of the no-load phase-to-neutral voltage is called the Residual Component RIF.

Termination Both ends of the main network bus must be terminated to avoid transmission reflections. The effective network data bus may be made up of several different physical buses. The Terminator is a RC circuit that matches the impedance of the physical media.

Terminator

Token-Ring Topology All of the devices or nodes are connected to one another in the shape of a closed loop. Ring topologies are relatively expensive to install, but they offer high bandwidth and can span larger distances.

Topology The physical shape of a network. There are three principal topologies: multi-drop bus, token-ring, and star.

Transfer Switch

A transfer switch is an electrical device for switching loads between alternate power sources. An automatic transfer switch monitors the condition of the sources and connects the load to the alternate source if the preferred source fails.

Utility The primary producer/distributor of electric power. In some countries it’s called the utility source; in some others it is called the mains or “hydro.”

Undershoot

Undershoot refers to the amount by which voltage or frequency drops below the nominal value as the voltage regulator or governor responds to changes in load.

Volt

The volt is a unit of electrical potential. A potential of one volt will cause a current of one ampere to flow through a resistance of one ohm.

Voltage Control The voltage control is a rheostat that sets the operating point of the voltage regulator and therefore controls the output voltage of the generator set, within its design limits.

Voltage Dip

Voltage dip is the dip in voltage that results when a load is added, occurring before the regulator can correct it, or resulting from the functioning of the voltage regulator to unload an overloaded engine-generator.

Voltage Regulation

Voltage regulation is a measure that states the difference between maximum and minimum steadystate voltage as a percentage of nominal voltage.

Warning A type of fault which does not shut down the engine or generator set, but is meant to warn the user or operator of an out of normal condition which could eventually adversely affect operation of the Genset (i.e. could shut it down or prevent it from starting or operating properly).

Wye Connections A Wye connection is the same as a star connection. It is a method of interconnecting the phases of a three-phase system to form a configuration resembling the letter Y. A fourth (neutral) wire can be connected at the center point.

Zero Sequence Zero sequence is a method of ground fault detection that utilizes a sensor (CT) that encircles all the phase conductors as well as the neutral conductors. The sensor will produce an output proportional to the imbalance of ground fault current in the circuit. This output is then measured by a relay to initiate circuit breaker tripping or ground fault alarm.

PC 3.3 REAL TIME CLOCK & EXERCISE

Appendix A

PC 3.3 Real Time Clock The PCC3300 control system includes a real time clock function. The Real Time Clock (RTC) is used for calculating controller on time, recording fault occurrence times, supporting factory test, and for the automatic scheduler feature. Once programmed, the real time clock accurately* calculates seconds, minutes, hours, date of the month, month, day of the week, and year with leap year compensation valid up to 2100. The clock operates in 24 hour format and automatically adjusts the end of the month for months fewer than 31 days.

When battery power is removed from the PCC3300, the RTC remains powered via internal circuitry on the PCC3300. The internal circuitry will provide power to the RTC for about one hour, after which the RTC will become reset to 0 Seconds, 0 Hour, 0 Minutes, 0 Month, 0 Date, 0 Year. Under this condition, the “RTC Power Interrupt” Fault (1689) will become active indicating that the clock needs to be reset.

The RTC also has supports Daylights Savings Time, which is a convention used to advance the time by one hour so afternoons have more daylight then mornings. The DST logic adds the DST Adjustment time to the current time when the current time is equal to the DST Start Time. The DST logic subtracts the DST Adjustment time from the current time when the current time is equal to the DST End Time. To Enable DST, the trim Daylight Savings Enabled needs to be set to Enabled. To setup DST, specify the values for the following trims.

PC 3.3 Exercise Scheduler The exercise scheduler is a feature that automatically starts the genset for exercise. This feature prevents common problems which result from mechanical equipment sitting for long periods of time. In order for the automatic exerciser to work, the PCC3.3 control system needs to be in ‘Auto’ mode, the RTC needs to be set (Fault 1689 is not active), and the trim Exercise Scheduler Enable needs to be set to Enable.

The PCC3.3 can be programmed to run up to 12 independent programs, all which can either be one time events or repeating events. Furthermore, each program can be programmed to exercise the genset in two run modes, no load and with Load.

Each independent program has the following trims which establish its behavior. “X” can have a value from 1 thru 12, once for each available program.

PC 3.3 REAL TIME CLOCK & EXERCISE

Appendix A

The following are a set of rules used to define schedules and exceptions – 1. If there is a running program and the next programmed program(s) overlap with the existing running program, the existing program will run as it is and next overlapping program(s) will not start even, if the first program is expires before the next overlapping program is scheduled to stop. 2. If program is running and exception becomes active, the PCC3.3 control system will ignore the newly activated exception(s) and will continue to run the active program expires. 3. If there is an active exception and the next exception(s) overlap with the existing active exception, the existing exception will continue to be active as it is and the next exception(s) will be ignored. 4. If an exception and program are scheduled to become active at the same time, then the exception will become active and the program will be ignored. 5. If a program is active and running (or an exception is active) and control system loses power before the program or exception can expire, the active program or exception will not be started again when power is restored to the control system even if there is time remaining in the program/exception.

Remote Start command behavior on exercise scheduler – While in exercise scheduler mode,{ ie a scheduled program is active and control system is in ‘Auto’ mode,} if the PCC3.3 control system receives a remote start command, the genset will continue to run. If remote start command is removed and the exercise scheduler program is still active, the genset will continue to run until scheduler time lapses.

PC 3.3 ModBus

USING MODSCAN SOFTWARE ModScan is a software tool that can help you verify ModBus communications from the PowerCommand control. It is not a Cummins Power Generation product, it is a product designed by WinTech for general use in any ModBus serial communication system. The use of ModScan enables a CPG technician to prove ModBus communications from a CPG controls system to a neutral third party software. The following directions and examples apply to using ModScan with PCC 1301 and 1302 genset controls. Refer to the appropriate register map for specific registers available.

FIGURE 1. MAIN MODSCAN SCREEN

Use ModScan software after you have enabled your ModBus setup in the control. A standard PCC 1300 series service cable must be installed between the PC serial port and the TB-15 connector on the PCC 1302 control board. PC serial ports communicate using RS232 so a RS485 converter must be used. Figure 1 show the initial screen displayed upon launching the program.

FIGURE 2. MAIN MODSCAN SCREEN

1. From the tool bar, select: Connection Connect. The Connection Details dialog box is displayed (see Figure 3). The “Connect Using” is used to designate the proper communication port on your computer.

2. Use the pull down menu under “Connect Using” to select the comm port you wish to use. A typical configuration would be set to: Baud Rate: 19200, Word Length:8, Parity: None, Stop Bits: 1, (as shown in Figure 3.) Use the pull down menus to change these settings as necessary.

3. Click on the “Protocol Selections” button and change the Transmission Mode to “RTU” (see Figure 4). Do not be concerned with settings in the other boxes. Click “OK” button.

FIGURE 4. MODBUS PROTOCOL SELECTION DIALOG BOX

4.Click “OK” on the two open dialog boxes. You should notice in the upper right of the dialog box, the “Number of Polls” counter incrementing. Notice the message at the top of the register list captured by **____**. In Figure 4-2 the message **MODBUS Exception Response from Slave Device ** is indicating the device has responded, but there is a problem with one or more messages in the poll length. If the **____** line states **MODBUS Message TIME-OUT** ModScan is not able to find anything at the other end of the communication wire. There could be many reasons for this. Check your computer comm.. port, the wire, if the PCC 1302 is powered up, if ModBus is “Enabled”, or if the PCC 1302 “ModBus Setup” matches the Protocol settings on Figure 3 & 4.

FIGURE 4-2. MODBUS DIALOG BOX INFORMATION

5. On the main ModScan screen (see Figure 5), Change the Address to 0064, the Length to 1. ModScan is not satisfied if it polls a group of registers and finds one in the sequence that is not programmed, it will display a “Exception Response” as in Figure 4-2. Minimize the number of registers polled to a sequential length as listed in the register map. WARNING

6. From the MODBUS Point Type pull down menu, select “03: HOLDING REGISTER.” The PCC 1300 series communicates all registers as a HOLDING REGISTER. Refer to any of the preceding mapping registers to view different pieces of data. The “Valid Slave Responses” should now be incrementing as the data on the screen is updated. You should see a single register displayed with a 5 digit value. Poll the following register addresses for the Genset. 40061 is Battery voltage at the control. 40064 is Coolant Temp. (This value will be displayed in Celsius ONLY) 40070 is Eng Runtime (value will be displayed in seconds) Page 4

FIGURE 5. MODBUS POINT TYPE = HOLDING REGISTER

7. On the main ModScan menu (see Figure 6), change the Length to 1. Refer to the warning in step 5. Accidental starting of the generator set can cause severe personal injury or death. During step 8, a “start” command is sent to the genset. If the genset is in the Auto mode, the genset WILL start. WARNING

8.To output a value to the genset control, poll the desired address, (In this case we want to test the start command which is register #40300) double click on register 40300. The Write Register dialog box is displayed (see Figure 6). If you enter a value of “1” and select “Update,” Genset #1 starts and runs. If you double click on register 40300 again, enter a value of “0,” and selecting “Update;” the Genset stops. 9. Review the mapping register information for other coils that you can manipulate.

ModScan Read & Write Commands ModScan has more ability to test and command ModBus devices than is presented in this guide. There are other features used on some of the other PowerCommand ModBus systems, but the processes and examples so far listed will enable a technician prove to a customer or system integrator that the PCC 1301 or 1302 will communicated properly.

Notes The following notes apply to using ModScan with PCC 1301 and 1302 genset controls. Refer to the appropriate register map for specific registers available.

Genset Control

ƒ Start/Stop - When this register is set to “1,” the genset starts, and ramps to operating speed. As long as this register remains a “1,” the genset will continue to run. When this register is set to “0,” the genset stops.

ƒ Fault Reset - This should be a momentary signal of about 2 seconds duration. Entering a “1” in the fault reset register resets any non–active warning and, If there is not a remote start on the genset, it resets any non–active shutdown except the Emergency Stop.

ƒ Emergency Stop - When this register is set to “1,” the emergency stop is active at the PowerCommand control. The emergency stop cannot be rest until this register is set to “0.” After the register is reset to “0,” the emergency stop must be reset at the PowerCommand control. It cannot be reset remotely.

Miscellaneous

ƒ Fault State - As part of Gen Status State, digital value 4 (Fault State 1) = shutdown with an active run command (cannot be remotely reset) and digital value 5 (Fault State 2) = shutdown with no active run command (can be remotely reset).

ƒ ƒ

Fault Code - This register contains the fault code number of the currently active fault. See service manual for list of supported fault codes. Fault Type - This register contains the fault type of currently active fault 0=Normal 1=Warning 2=Derate (this is a feature NOT currently supported by the PCC 1300 series) 3=Shutdown with Cool down 4=Shutdown

ƒ

Fault bypass (battle short) feature enable – Activation of battle short via ModBus is just as serious as any other activation of battle short.
