2. Control System 2.1 Control System Description The control system is used to start and stop the generator set, and provides full generator set monitoring capability and protection in a stand-alone situation (non paralleling) from the display screen. It monitors the engine for temperature, oil pressure, battery voltage, estop and genset hours, and provides voltage and current metering. In the event of a fault the unit will indicate the fault type and automatically shut down the generator set on critical faults. All indicators, control buttons and the display screen are on the face of the display module as illustrated in Figure 1. There are two fault level signals generated by the control system as follows: •

Warning: - signals an imminent or non-critical fault for the engine. The control provides an indication only for this condition.

•

Shutdown: - signals a potentially critical fault for the engine. The control will immediately take the engine OFF-load and automatically shut it down.

The standard control system operates on 12 VDC battery power. The auxiliary equipment operates on LV AC power. The history data is stored in non-volatile memory and will not be deleted due to loss of battery power.

2.2 Operating Modes The PowerStart 0500 control is operated by the Manual / Start / Stop / Auto buttons on the display module face.

2.2.1 OFF Mode Note: Some published control service literature may refer to this mode as the STOP mode. When in the OFF mode, the control does not allow the generator set to start. Refer to Section 4.2.7 – Auto and Manual Run Modes – to re-start the generator set. If the generator set is running, in either Manual Run or Auto mode, and the Stop button is pressed, a normal shutdown sequence will be initiated. In OFF Mode the red LED above the Stop button will be lit.

2.2.2 Manual Run Mode When in Manual Run mode, the generator set starts and continues to run until the control is put into the OFF mode. Pressing the Stop button initiates a normal shutdown sequence that does not include a time delay stop. While in the Manual Run mode, any remote start signal is ignored.

2.2.3 Auto Mode When in Auto mode, the control allows the generator set to be started at any time, with a remote signal only. When a remote start signal is received, the generator set starts after a time delay start is completed (default delay is zero seconds). When a remote start signal is removed, the control performs a normal shutdown sequence which includes a time delay stop (default delay is zero seconds). If the generator set is running in Auto mode and the Stop button is pressed, the control immediately stops the generator set and the control transitions to the OFF mode.

2.2.4 Sleep Mode The PowerStart 0500 control enters a low power (Sleep) mode of operation where the current drawn is less than 60 milliamps (DC) at normal battery voltage levels. Sleep mode is automatically enabled, and the display module will turn itself OFF after five minutes of keypad inactivity when in OFF mode. When in Auto mode, the Sleep mode is enabled only when the trim “Wake in Auto Enabled” is enabled. If the trim is disabled (which is the default value), the Sleep mode will never be enabled when in Auto mode. It awakes from the sleep mode if the reset button is pressed or if there is a Tool wakeup input or a Remote Start signal is received or an E-stop signal is received both in Stop as well as Auto mode.

7

The control will not enter the Sleep mode if there are any active, unacknowledged, shutdown faults or if the control is in the Manual Run mode.

2.2.5 Battle Short Mode The purpose of Battle Short Mode is to satisfy local code requirements, where necessary. Battle Short mode is a generator set mode of operation that prevents the generator set from being shutdown by all but a few, select, critical shutdown faults. Caution:

All shutdown faults, including those overridden by Battle Short, must be acted upon immediately to ensure the safety and well being of the operator and the generator set.

WARNING: USE OF THE BATTLE SHORT MODE FEATURE CAN CAUSE A FIRE OR ELECTRICAL HAZARD, RESULTING IN SEVERE PERSONAL INJURY OR DEATH AND/OR PROPERTY AND EQUIPMENT DAMAGE. OPERATION OF THE SET MUST BE SUPERVISED DURING BATTLE SHORT OPERATION. This feature must only be used during supervised, temporary operation of the generator set. The faults that are overridden when in Battle Short mode can affect generator set performance, or can cause permanent engine, alternator or connected equipment damage. Only trained and experienced service personnel should enable this feature. When shipped from the factory, this feature is disabled. Caution:

If this mode of operation is selected, the protection of load devices will be disabled. Cummins Power Generation Limited will not be responsible for any claim resulting from the use of this mode.

Note:

The Battle Short feature must be enabled or disabled using the PC Service tool.

When Battle Short mode is enabled (Default is Disabled), the Warning status indicator lights, and code 1131 – Battle Short Active – is displayed. When Battle Short mode is enabled and an overridden shutdown fault occurs, the shutdown lamp remains lit even though the set continues to run. Fault code 1416 – Fail to Shutdown – is displayed. If the OK button is pressed to acknowledge the fault, the fault pop up is cleared from the display but remains in one of the scrolling screens displaying the fault code and its description to indicate that it is an active fault as long as Battle Short mode is enabled. Battle Short is suspended and a shutdown occurs immediately if any of the following critical shutdown faults occur: •

Speed Signal Lost (Loss of Speed Sense)

Fault code 121

•

Overspeed

Fault code 234

•

Local Emergency Stop

Fault code 1433

•

Excitation Fault (Loss of Voltage Sense)

Fault code 2335

•

Fault code 1123 – Shutdown After Battle Short – is then displayed.

2.5 Sequence of Operation The generator set is run automatically using a Remote Start signal, or Manually using the generator set control panel buttons. LEDs are provided on the display module front panel to indicate the operating run mode of the generator set. The PowerStart 0500 control initiates a starter cranking signal and will perform an automatically sequenced manual start, under a complete engine protection system combined with full monitoring capability. If a fault is sensed at Start-up, the engine is locked out and will not start. The choice of Auto or Manual run mode is decided by authorised personnel during the generator set initial setup.

2.5.1 Starting Before attempting to start the generator set, the operator should read through this entire manual, together with the Health and Safety manual and the specific engine manual provided as part of the documentation pack supplied with the generator set. It is essential that the operator be completely familiar with the generator set and the PowerStart 0500 control. The following sub-sections cover the systems used to start and stop the generator set. Before starting the generator set, make sure that exhaust and fuel fittings are tight and properly positioned, and that proper maintenance and pre-start checks have been performed. The generator set can be configured for a number of starting cycles (one to seven) with set times for crank and rest periods for all starting modes (manual/remote). The default setting is for three start cycles, composed of fifteen seconds of cranking and 5 seconds of rest.

2.5.2 Starting at Display Panel (Manual Run Mode) To start the generator set in the Manual Run mode, press the Start button within 10 seconds of pressing the Manual button. Follow the instructions in Section 4.2.9 (Selecting Manual Run Mode). Note: Any Remote Start/Stop signal is ignored whilst in Manual Run Mode. The PowerStart 0500 control will initiate a starter cranking signal and will perform an automatically sequenced manual start, under a complete engine protection system combined with full monitoring capability. This will activate the engine control system and the starting procedure. The starter will begin cranking, and after a few seconds the engine will start and the starter will disconnect. In the Manual Run mode the control will not complete the Time Delay to Start or Time Delay to Stop. The Remote Start red LED, and the Manual Run, green LED will be lit. If the engine does not start, the starter will disengage after a specified period of time and the control will indicate a Fail to Start Shutdown.

15

Wait a minimum of two minutes for the starter motor to cool and then repeat the starting procedure. If the engine does not run after a second attempt, refer troubleshooting guidelines.

2.5.3 Starting from Remote Location (Auto Mode) To start the generator set in the Auto Run mode, press the Auto button from the menu bar of the display module front panel. Follow the instructions in Section 4.2.8 (Selecting Auto Mode). The Auto, green LED will be lit. Only on receipt of a remote start signal, and after a Time Delay to Start, will the PowerStart 0500 control initiate the starting sequence as above. The Remote Start LED will be lit.

2.6 Stopping 2.6.1 Stopping at Display Panel (Manual Mode) The module will not respond to any Remote Stop signal whilst in Manual Run Mode. When in Manual run mode, pressing the Stop button will initiate a normal (Manual) shutdown sequence. In the Manual Run mode the control will not complete the Time Delay to Stop. Note: Remove load and run set for five minutes to reduce engine heat before pressing the OFF button.

2.6.2 Stopping from Remote Location (Auto Mode) In Auto mode, the control allows the generator set to be started with a Remote Start Signal only. If the control receives a Remote Stop signal, the generator set will complete its normal shutdown sequence which includes a Time Delay Stop (Default is zero seconds). If the generator set is running in Auto mode and the Stop button is pressed, the control immediately stops the generator set without completing the Time Delay to Stop and the control transitions to the OFF mode.

2.6.3 Emergency Stop (Code 1434) The Emergency Stop Button is situated on the front of the Control Panel. This is a mechanically latched switch that will unconditionally stop the engine when pressed, bypassing any time delay to stop. Push this button in for Emergency Shutdown of the engine. Note : If the engine is not running, pushing the button in will prevent the starting of the engine, regardless of the start signal source (Manual or Auto - remote). When the Stop Button is pressed the display panel will indicate the Shutdown condition by illuminating the red Shutdown status LED graphical LCD display:

4. Troubleshooting 4.1 Introduction Fault codes information together with Warning and Shutdown information is provided in this section to assist in locating and identifying the possible causes of faults in the generator set system. Refer also to the Operator’s engine specific manual supplied as part of the generator set documentation pack. This latter manual will contain further information regarding the running and care of the generator set and also specific equipment instructions that may differ from the standard generator set.

4.2 Control Unit The generator set control system continuously monitors engine sensors for abnormal conditions, such as low oil pressure and high coolant temperature. If any of these conditions occur, the control will light a yellow Warning lamp or a red Shutdown lamp and will display a message on the graphical display panel. In the event of an engine shutdown fault (red Shutdown LED), the control will stop the engine immediately. This section lists the Warning and Shutdown Fault Codes/Messages and suggests possible causes of the fault.
