Indicator Lamps
The functions of the indicator lamps are designed to display the maximum amount of information on the minimum number of lamps. The layout and the function of the indicator lamps is dependent on the type of control panel. The following types of control panel are used:
- Electronic Modular Control Panel (EMCP3)
- Marine Class Society (MCS) control panel
EMCP3 Control Panel

EMCP3 Control Panel (1) Display Screen (2) "Alternator Overview" push button (3) "Engine Overview" push button (4) Yellow Warning Lamp (5) Red Shutdown Lamp (6) Alarm Acknowledge/Silence push button (7) "Lamp Test" push button | |
On the EMCP3 control panel, two lamps are installed. The lamps are the "Warning" lamp (4) and the "Shutdown" lamp (5) .
(4) Yellow Warning Lamp - A flashing yellow warning lamp indicates that there are active warnings that have not been acknowledged. In order to acknowledge the warnings, press the Alarm Acknowledge/Silence key (6). If there are no longer any active warnings, then the lamp will turn off. If active warnings still exist, then the lamp will change from flashing yellow to solid yellow. A solidly illuminated yellow warning lamp indicates that there are acknowledged warnings that are still present.
(5) Red Shutdown Lamp - A flashing red shutdown lamp indicates active shutdown events that have not been acknowledged. In order to acknowledge the shutdown events, press the Alarm Acknowledge/Silence key (6). If there are no longer any active shutdown events, then the lamp will turn off. If active shutdown events still exist, then the lamp will change from flashing red to solid red. A solidly illuminated red shutdown lamp indicates that there are active shutdown events that have been acknowledged.
Note: Any condition that has caused a shutdown event must be manually reset.
There is also a "Lamp Test" push button (7) .
The "Alternator Overview" push button (2) can be used to display output information for the alternator on the display screen (1). Refer to the documentation for the control panel for more information.
The "Engine Overview" push button (3) can be used to display engine information and event codes on the display screen (1) .
MCS Control Panel

(1) Maintenance lamp (2) Diagnostic lamp (3) Maintenance reset push button (4) Warning lamp for the Electronic Control Module (ECM) (5) Lamp for the shutdown override mode (6) "INFO" push button (7) Alarm indicator (8) Display (9) "LOG" push button (10) Lamp test push button | |
On the MCS control panel, the following lamps are installed:
- The "Maintenance" lamp (1)
- The "Diagnostic" lamp (2)
- The "Warning" lamp (4)
- The "Shutdown Override" lamp (5)
- The "Alarm" indicator (7)
Maintenance Lamp (1) - The maintenance lamp will illuminate when the ECM indicates that maintenance is required on the engine.
Diagnostic Lamp (2) - The diagnostic lamp will display the flash code when a diagnostic code has been generated by the Electronic Control Module (ECM). Refer to "Flash Codes" for more information.
Warning Lamp for the ECM (4) - This lamp will illuminate when the engine ECM indicates a fault within the system. The engine will not start if the warning lamp for the ECM is illuminated.
Lamp for the Shutdown Override Mode (5) - This is illuminated when the engine shutdown override switch inside the control panel has been set to the override setting. This lamp will illuminate in order to indicate that the engine shutdown will occur if an overspeed condition occurs. All other normal override parameters are ignored.
Alarm Indicator (7) - A flashing LED indicates that alarms that have not been acknowledged are still present. A fixed LED indicates that all alarms are acknowledged. A red LED indicates shutdown. A green LED is for an alarm.
The following items on the control panel are also used to reset warning lamps and gain to access engine information:
Maintenance Reset Push Button (3) - When the maintenance lamp is illuminated and all the necessary maintenance has been completed, the maintenance reset push button must be pressed in order to extinguish the maintenance lamp.
"INFO" push button (6) - This shifts the display in order to show the list of alarms. The list has a maximum of 30 alarms. A history that displays the last 30 alarms can be viewed.
Display Area (8) - The display area shows information about the generator set.
"LOG" push button (9) - This key shifts the display to the three lower lines in order to show the events and a list of alarms. The list holds 100 events. These events are erased when the main unit is switched off.
"Lamp Test" push button (10) - The lamp test push button is used to test the indicators on the control panel.
Flash Codes
Note: The following information is only applicable to gensets that use an MCS control panel.
The "Flash Code" feature is used to flash the two digit code of all active diagnostic and event codes. Refer to the Troubleshooting Guide, "Diagnostic Codes" for the flash code that is related to the diagnostic code or an event.
When a diagnostic code or an event code is active or logged, the diagnostic lamp will flash repeatedly in order to indicate the codes.
Each flash will be on for half a second and off for 300 milliseconds. The "Diagnostic" lamp will remain off for two seconds between each digit of a code. If there is more than one diagnostic code, the "Diagnostic" lamp will go off for five seconds. The lamp will then flash in order to indicate the next code.
As an example, an active diagnostic code of "21" is indicated by the "Diagnostic" lamp coming on for 500 ms, then off for 300 ms, then on for 500 ms, then off for 2000 ms, then on for 500 ms and then off.

Once all codes have been flashed, the "Diagnostic" lamp will go off for a period of 15 seconds before starting the sequence again.
Note: Flash codes are always sent in ascending numerical order.
