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 (EMCP 4.2)
- Marine Class Society (MCS) control panel

On the EMCP 4.2 control panel, two lamps are installed. The lamps are the "Warning" lamp (above the Alarms Acknowledge key) and the "Shutdown" lamp (above the Reset Shutdown key).
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 Alarms Acknowledge key (1). 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.
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 Alarms Acknowledge key (1). 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.
The "AC Overview" key (15) can be used to display output information for the alternator on the display screen (16). Refer to the documentation for the control panel for more information.
The "Engine Overview" key (14) can be used to display engine information and event codes on the display screen (16) .

Overspeed Lamp (19) - The overspeed lamp will illuminate when the ECM detects that an engine overspeed has occurred.
Coolant Temperature Lamp (20) - The coolant temperature lamp will illuminate when the ECM detects that the coolant temperature has exceeded a defined value.
Low Oil Pressure Lamp (22) - The low oil pressure lamp will illuminate when the ECM detects that the oil pressure has dropped below a defined value.
Shutdown Override Lamp (24) - The shutdown override lamp will illuminate when the shutdown function has been disabled.
Maintenance Lamp (26) - The maintenance lamp will illuminate when the ECM calculates that maintenance is required on the engine.
Alarm Lamp (44) - 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.
