The operator is notified of abnormal engine operating conditions by the Main Display Module. The Main Display Module flashes the Alert Indicators ON and OFF. The Main Display Module uses the signals from the following sources.
switch inputs
sensor inputs
sender inputs
engine ECMThe Main Display Module receives information from the engine ECM through the CAT Data Link. The information is used to determine when a condition requires flashing a lamp. When an indicator flashes, an abnormal engine condition exists.Engine System Status - redActive System Diagnostic/Shutdown - redThis lamp indicates that there is an active diagnostic code present, an event present, or the engine ECM has initiated a shutdown. The information is received from the engine ECM through the CAT Data Link.Note: Diagnostics can be viewed from the main display module. Events can not be viewed from the main display module. Events can be viewed with the CAT Electronic Service Tool.Low System Voltage - redThis lamp indicates that the DC Voltage of the system or the voltage of the alternator is low.Note: The default value for the trip point is programmable. The Electronic Service Tool can be used to reprogram this setting to values that are between 20 DCV and 22 DCV. The information about the low system voltage is received from the engine ECM through CAT Data Link. The information about the system voltage may also be received from a "Battery Charger Failure" switch input that is connected to pin 20 of the connector for the Main Display Module. The "Battery Charger Fault" switch must be installed by the customer.Engine Overspeed - redThis lamp indicates that the engine ECM has detected an engine overspeed condition.Note: The default value for the trip point is programmable. The Engine Overspeed can be reprogrammed to a value that is between 1200 rpm and 2400 rpm with the Electrical Service Tool. The information is received from the ECM through the CAT data link. For more information about the engine ECM and the setpoints, refer to the Troubleshooting Guide.Overcrank - redGenerator Set Only - This lamp illuminates when the engine ECM detects that the engine did not start after cranking or the engine did not start after cycle cranking for the programmed limit. If the engine fails to start within a programmed amount of time, the engine ECM will stop the starting sequence. The Main Display Module flashes the Overcrank fault indicator. Another attempt to start the engine cannot be made without placing the Engine Control Switch (ECS) in the OFF/RESET position first. The information about an Overcrank is received from the engine ECM through the CAT data link.Not In AUTO - redGenerator Set Only - This lamp indicates that the Engine Control Switch is not in the AUTO position. Remote starting of the engine is only possible when the ECS is in the AUTO position. The information is received from the engine ECM through the CAT Data Link.Marine Gear Oil Pressure - redMarine Propulsion Only - This lamp indicates that the marine gear transmission oil
