General description

2.1

Introduction

Description

ES 6, general view

The ES 6 is a stand-alone central control system that regulates the net pressure within programmable limits by starting and stopping, loading and unloading (in case of fixed speed compressors) or controlling the speed (VSD compressors) of the connected compressors according to a programmed algorithm (see section Equal wear sequence mode). Up to six compressors, connected to a common air net, can be connected. The ES 6 can control fixed speed compressors as well as frequency converter driven compressors (VSD). Fixed speed Atlas Copco compressors may have any Elektronikon® regulator or may be pressure switch controlled. VSD compressors must however have an Elektronikon® regulator of the fourth (MkIV) or fifth generation (Mk5) in order to have all control options. Competitor VSD compressors can only be started and stopped by the ES 6 via digital contacts. The status of each compressor can be checked on the display. Operating parameters are accessible via the menu. The ES 6 consists out of a metal cubicle with: • • • •

An Elektronikon® Graphic Plus controller (Mk5) An expansion module type I/O 2 (part number 1900 5200 31) A 4-20 mA pressure transmitter (delivered loose) A supply transformer, fuses and connectors

Controller types Over the past years, many different versions of the Elektronikon® regulator are developed. A short survey:

Single point pressure measurement

Description

The ES 6 measures the net pressure by means of a 4-20 mA pressure transmitter (P), connected to the I/O 2 module in the ES 6 cubicle. The ES 6 controls the compressors in the network in order to keep the pressure within the limits of the programmed pressure band. As an alternative or as backup, another pressure sensor (0-5 V transducer) can be used. This other or extra sensor must be connected to the I/O2 module.

Two pressure bands are available. A switch-over between the pressure bands can be performed in different ways (week timer based, controlled by a switch, via the display menu or via CAN communication).

2920 7094 70

2.3

Equal wear sequence mode

Description In this operation mode, the ES 6 controls the connected compressors in function of the outcome of following checks: • • • •

Position of the measured pressure versus the selected pressure band Priority check Compressor availability check Equal wear check

Priority check Two priority schemes are available. In each priority scheme, six priority levels can be set. The lower the number of the priority level, the higher the priority: machines of level 1 will be started first, those of level 6 will be started last. Each compressor can be given a different priority. Compressors with the same priority level will have the same priority. Within a group of compressors with the same priority, the VSD compressor (if available) will be the top load machine. The VSD compressor will be started first and stopped last within the priority group. The highest placed variable speed driven compressor will be the control VSD compressor. If more than one VSD compressor is put in this priority level, the one with the least number of running hours will be the control (top load) VSD. The other one(s) will be controlled as a fixed speed compressor, meaning that it (they) will run at its (their) maximum motor speed, when started. The controller allows two different ways of switching between the priority schemes: • Manual shift: a new scheme is selected manually. • Time based shift: the scheme shifts automatically according to a programmed list (e.g. Monday 07:00 h priority scheme 1, Tuesday 08:00 h priority scheme 2, etc.). Availability check Before a compressor in a group is started, an availability check is performed. This means that only the compressors that are running in unloaded condition or are ready to be started will be taken into account. A compressor is unavailable if: • • • •

The minimum stop time is not yet expired The compressor is shut down Its emergency stop button is pressed There is no communication with the ES 6

Equal wear Within the group of compressors that have the same priority, the available compressor with the least running hours will be started first, compressors with the most running hours will be stopped first. Exception: this is not applicable when the priority group contains the control VSD compressor. The other VSD compressor(s) will run as fixed speed compressor(s).

12

2920 7094 70

Instruction book

Temporary activation of a standby machine By using the priority schemes, a standby machine can be activated for a certain time to keep the machine in optimal condition. In the example below, the last machine (number 6) is set to standby (priority scheme 1). It is only activated when all the other machines are already running. To keep the machine in optimal condition, the sequence can be changed so that the standby compressor has the highest priority (priority scheme 2). This can be done by changing the schemes manually or by means of a timer based switch. Example Compressor number

Matching flow fluctuations with variable speed driven compressor(s)

Description If a variable speed driven compressor is installed, the latter is used to meet the changing demands of the air net. When two compressors are running, the fixed speed compressor runs 100% loaded while the variable speed driven compressor is used to fine tune the pressure. If a competitor VSD is connected, together with a number of fixed speed compressors, the competitor VSD needs to be controlled via remote start/stop command (small pressure band). Its setpoint must be set below the Pressure Band Low setting of the ES 6. When there is more than one VSD compressor, the Atlas Copco VSD compressor will be the control compressor. The competitor VSD will run as a fixed speed compressor.

Installation instructions

Procedure • Fix the ES 6 to a wall (e.g. in the compressor room), taking into account the following maximum cable lengths: • 250 m (820 ft) for a CAN network 500 m (1640 ft) if a repeater is installed, 970 m (3180 ft) if two repeaters and one CAN bridge are installed. • 1000 m (3280 ft) between the pressure transmitter and the ES 6. • The pressure transmitter should preferably be connected to an air receiver, in order to avoid pressure pulsations. Also vibrations should be avoided. It is also recommended to connect it via valves, allowing the pressure transmitter to be replaced after isolating and depressurising it. The pressure transmitter must be installed in an upright position to avoid accumulation of condensate in the device. • Isolate and depressurise the part of the air net to which the pressure transmitter will be connected. • Provide a threaded hole (ISO R 1/4) in the depressurised part of the air net. • Screw the pressure transmitter into place. • Wire the pressure transmitter cable to the module of the central control system. Respect the pin numbers as indicated on the electrical diagram, which is delivered with the device.

Connection methods

Communication

(2)

Connection channel 1 to 6

For each compressor a connection channel is provided. For the ES 6, six connection channels can be selected, configured and used to connect compressors. Physical connection possibilities There are three different ways to connect a compressor to the ES 6: 1. CAN (LAN) The CAN (Controller Area Network) allows all the compressors and controllers in a network to be connected to one another using a single 3 core cable, which is daisy-chained from one device to the next. The CAN network acts as a universal communication system which can be used for both control and monitoring. This type of connection uses the LAN connection of the regulator. 2. CANBox Interface For fixed speed compressors which cannot be connected directly to a CAN network, the CANBox interface can be used. This DIN rail mounted box acts as an interface between traditional digital and analogue I/O and the CAN network. One CANBox has to be provided per compressor. 3. Hard-wired The ES 6 can also control any fixed speed compressor using a series of digital inputs and outputs. In this case the compressor will need to be hard-wired to the ES 6. Connecting Atlas Copco compressors equipped with Elektronikon® MkIV or Mk5 regulators The simplest way to connect these machines to the ES 6 is via the CAN network. A single machine can be connected directly to the ES 6 or multiple machines can be linked together and then connected, as shown below:

16

2920 7094 70

Instruction book

Some older versions of the MkIV controller have limited control possibilities and do not allow proper control over the CAN network or simply have no LAN connection. In this case there are two options: • Replace the controller by the current version (see details below). • Connect the machine via hard-wiring. See section Hard-wired connections.

Connecting Atlas Copco machines with Elektronikon® MkIII This previous generation of the Elektronikon® controller came in two variants, a low range and a high range version. One of the key differences between these two variants were the communication possibilities. The details below explain the possibilities for each variant: • Elektronikon® MkIII Low Range controller (part number 1900 0700 0x) There are two connection possibilities for this controller: either a CANBox Interface can be used (part number 1900 0712 61), which means that the machine will use the CAN network to communicate with the ES 6 or the machine can be hard-wired directly to the ES 6. In both cases some simple changes will be necessary inside the electrical cubicle. More specifically two relays must be added, one to signal the running status and the other to signal the load/unload status. • Elektronikon® MkIII High Range controller (part number 1900 0701 0x) If the high range version of the MkIII includes an extra module known as COM 1, the easiest way to connect the machine to the ES 6 is to add a Combox-S interface (part number 8092 2482 54), which converts all communication to CAN. Alternatively the compressor can be hard-wired directly to the ES 6. If the machine does not include a COM 1 module there are three possibilities: • Use both a COM 1 (part number 8104 0115 00) and a Combox-S • Use a CANBox interface (part number 1900 0712 61) 2920 7094 70

17

Instruction book

• Hard-wire the machine directly to the ES 6

Connecting Atlas Copco machines fitted with Elektronikon® MkI or MkII The Combox-S is the easiest option to install and provides the most flexible and complete communication mechanism. Therefore this is the recommended connection method for the ES 6.

18

2920 7094 70

Instruction book

Connecting Electo-pneumatic machines and non Atlas Copco machines There are two ways to connect these machines to the ES 6: • Add a CANBox Interface (part number 1900 0712 61) to each machine and then use the CAN network • hard-wire each machine directly to the ES 6

Example for service level (A): The figures at the left are the programmed service intervals. For Service interval A, the programmed number of running hours is 4000 hours (upper row, green) and the programmed number of real time hours is 8760 hours, which corresponds to one year (second row, blue). This means that the controller will launch a service warning when either 4000 running hours or 8760 real hours are reached, whichever comes first. Note that the real time hours counter keeps counting, also when the controller is not powered. The figures within the bars are the number of hours to go till the next service intervention. In the example above, the compressor was just started up, which means it still has 4000 running hours or 8280 hours to go before the next Service intervention.

System configuration

System setup After all physical connections are made, a number of selections still has to be made in order to perform a system setup. This can be done via the ES 6 display or via special software, available to the Aftermarket organization. For setup via the display, most settings can be viewed/changed via the ES menu. Following steps have to be followed: 1. Master settings • Activate the ES in the Master controller:

Automatic Restart

Auto Restart After Voltage Failure • When 'Does not Exist', ARAVF is not present (cannot be activated in this screen). • When 'Exist but not active', ARAVF is present but not yet active. Can be activated on the display. • When 'Exist and is active': ARAVF is present and Active. Can be de-activated on the display. • When 'Exist and is active infinite': ARAVF is present, active and a restart will always be executed independent of Power Off time. See section Menu settings.

(1)

Scheme 1 Priority

Two priority schemes are present. In each Priority scheme a Priority Level can be set per compressor. The lower the priority level the higher the priority. Compressors with the same Priority Level will have the same Priority. By default all priorities in both schemes are set to 1. Since two Priority schemes are available, a switch over from one to the other Priority Scheme is possible (by Digital Input, Week Timer or via Display Menu) .

Start/Load Reaction Time

Maximum time for the compressor to reply to a Start/ Load command.

(4)

Load Reaction Time

Maximum time for the compressor to reply to a Load command.

(2)

Stop Reaction Time

Maximum Time for the compressor to reply to a Stop command.

(3)

VSD Maximum Starts per Day

The second up to sixth VSD compressor will be seen as a Fixed Speed compressor running at optimal/ maximum speed. Since these VSD's are seen as fixed speed compressors, a 'Number of starts per day' is required for the regulation.

(4)

VSD Maximum RPM Factor

Percentage of Control VSD Speed: required for the decision to start/load/unload and stop fixed speed and maximum speed VSD's.

(1)

VSD Minimum RPM Factor

Percentage of Control VSD Speed: required for the decision to start/load/unload and stop fixed speed and maximum speed VSD's.

(2)

VSD Zero RPM Band Factor

Percentage multiplied with the 'Minimum Speed' to decide that the Control VSD can be considered as stopped.

(3)

Running Hours

Running hours are the hours of the selected slave compressor

(4)

Mode

A user can change to integrate a compressor in the ES or isolate a compressor.

Manual Sequence group

Each slave must be put in a group. These groups we need to define a manual sequence.

Start-up

Preparations for initial start-up • Stick labels near the control panels of the compressors connected to the ES 6 as well as on an obvious place inside these compressors, warning the operator that the compressor is remotely started and stopped by a remote controller. These labels must also warn the operator that, after voltage failure, the controller can remotely start and stop the compressors, depending on the air demand and programmed values. • Connect the power supply cables of the ES 6 controller to an appropriate single-phase voltage. • Switch on the voltage. The ES 6 is now ready for use.
