Colors of the LEDs
"Self Check ok" - Green
"Power" - Green when on
"Alarm" - Red
All events and all alarms are shown in clear text on the display. The unit will store up to 150 alarms and/or events in the memory, along with a date stamp and a time stamp that shows when the alarm and/or event has occurred. On all alarm and/or events a snapshot of all the measured values is kept. The parameters that caused the trip can be accessed on the display by the log button. All other parameters at the time of the trip can be accessed via the Utility SW.
Communication
The unit is equipped with two standard communications ports.
- Display communication, which is used for the connection between the main unit and the display.
- RS232 Mod-bus communication is used for the connection of the main unit and a PC. From the PC, the Utility SW can be used to upgrade the parameters, basic SW and to view status information under commissioning conditions. Since this is a simple RS232 Mod-bus communication port, the port can also be used by Caterpillar Technicians and Service Personnel to set options, parameters, or even as a test interface in order to get the measured values to a Caterpillar test system.

PUSHBUTTON FUNCTIONS
There are 14 pushbuttons on the display unit with the following functions:
"INFO" - Shifts the 3 lower lines of the display in order to show the alarm list (up to 30 alarms can be in the list).
"JUMP" - Enters a menu number selection. All settings have a specific number attached to them. Using the JUMP button enables the user to select and display any setting without navigating all the way through the menus (see later).
"ACK" - Acknowledges the alarm that is displayed.
"LOG" - Shifts the display 3 lower lines to show the event and alarm list. The list holds 100 events. These events are erased when the main unit is switched off.
| Moves the cursor to the left for maneuvering in the menus. |
| Increases the value of the selected set-point (in the setting menus). In the daily use display it is used for scrolling the second line displaying of generator values. |
"SEL" - Is used to select the chosen function (underscored selection in the lower line of the display).
| Decreases the value of the selected set-point (in the setting menus). In the daily use display it is used for scrolling the second line displaying of generator values. |
| Moves the cursor right for manoeuvring in the menus. |
"BACK" - Jumps one step backwards in the menu (to previous display or to the entry window).
"START" - Start of the generator set if "SEMI-AUTO" is selected.
"STOP" - Stop of the generator set if "SEMI-AUTO" is selected.
"MODE" - Changes the controller from manual to remote operation, illuminating the "Auto" LED.
LED FUNCTIONS
Display Unit

"Self check ok" - LED indicates that the unit is OK.
"Alarm inh." - LED fixed light indicates that the inhibit input is ON.
"Run" - LED indicates that the generator is running
(GEN.) OK - LED green light indicates that the voltage/frequency is present and OK.
"Remote" - LED indicates that remote mode is selected.
Main Unit
The main unit includes the following LEDs:
Note: Refer to Illustration 2.
"Power" - LED indicates that the auxiliary supply is switched on.

Local Operation
Use the following procedure in order to start the engine.
| NOTICE |
|---|
Ensure the keyswitch (Shutdown Override) (2) is turned off. The key should be removed and stored in a safe place for emergency use only. |
- Turn the battery supply for the Generator Set to the ON position.
The "Power" LED will illuminate immediately. The "Self check ok" LED will illuminate after a few seconds. The Generator Set is now ready to start.
Line 4 on the display at power up will read:
"SETUP V3 V2 V1"
The view that is being displayed is underlined. Use the left arrow button and the right arrow button to scroll between the 4 screens of the display.
- Make sure that the "Auto" LED is off. If the "Auto" LED is on press the "Mode" button once in order to extinguish the "Auto" LED and gain local control.
- Press the "Start" button.
If "V3" is selected, the display will indicate the current status in the start / run cycle. In other words, start prepare followed by start relay on.
- If the timer (preheat) is configured, then the timer (preheat) will be initiated. After the timer (preheat) has expired, the engine will begin to crank.
Note: When the engine starts, the starting motor is disengaged and the starting motor is locked out.
- If the engine did not start, then the control module will permit the starting motor to cool down for a predetermined amount of time. Once the cool-down timer has expired, the engine will crank.
Note: The "Failed to Start" fault will be displayed in V3 after 3 failed attempts to start the engine. The "Alarm" LED indicator will flash. If this occurs, press the "ACK" button to reset the alarm. Determine the reason that the engine failed to start before making further attempts.
- After the engine has started, the timer (safety) is activated. This function allows the engine to warm up so that no faults will occur. Once the timer (safety) has expired, fault protection is available. The generator load may now be applied to the engine.
- If the timer (preheat) is configured, then the timer (preheat) will be initiated. After the timer (preheat) has expired, the engine will begin to crank.
- To stop the engine remove the load from the generator. Press and release the "STOP" button.
Remote Operation
Use the following procedure in order to start the engine.
| NOTICE |
|---|
Ensure the keyswitch (Shutdown Override) (2) is turned off. The key should be removed and stored in a safe place for emergency use only. |
- Turn the battery supply for the Generator Set to the ON position.
The "Power" LED will illuminate straight away. The "Self check ok" LED will illuminate after a few seconds. The set is now ready to start.
Line 4 on the display at power up will read:
SETUP V3 V2 V1
The view displayed is underlined. Use the left arrow button and the right arrow button in order to scroll between the 4 screens of the display.
- Ensure the "Auto" LED is on.
If the auto LED is off press the "Mode" button once to illuminate the auto LED to gain remote control.
- Close the "Remote Start" switch.
Note: If "V3" is selected, the display will indicate the current status in the start / run cycle. In other words, start prepare followed by start relay on.
- If the timer (preheat) is configured, the timer (preheat) will be initiated.
After the timer (preheat) has stopped timing, the engine will begin cranking.
Note: When the engine starts, the starting motor is disengaged and the starting motor is locked out.
- If the engine did not start, then the control module will permit the starting motor to cool down for a predetermined amount of time. Once the cool-down timer has expired, the engine will crank.
Note: The "Failed to Start" fault will be displayed in V3 after 3 failed attempts to start the engine. The "Alarm" LED indicator will flash. If this occurs, press the "ACK" button to reset the alarm. Determine the reason that the engine failed to start before making further attempts.
- After the engine has started, the timer (safety) is activated.
This function allows the engine to warm up so that no faults will occur. Once the timer (safety) has expired, fault protection is available. The generator load may now be applied to the engine.
- If the timer (preheat) is configured, the timer (preheat) will be initiated.
- To stop the engine remove the load from the generator. Open the "Remote Start" switch.
SHUTDOWN OVERRIDE
If the unit is to be used as an emergency generator set the automatic shutdown system may be locked out. In this mode any fault will give an indication but will not stop the engine.
