(1) Alert Indicators (2) Display Area | |
The operator is notified of abnormal operating conditions by the flashing indicators. The Main Display Module uses the signals from the following sources:
- switch inputs
- sensor inputs
- sender inputs
- information that is from the engine ECM
On the 3500 EUI, the engine ECM sends information to the control board through the CAT data link. The information is used in order to determine when a condition requires flashing an indicator. When an indicator flashes, an abnormal engine condition exists.

Emergency Stop or Engine Overspeed (Red Lamp)
This lamp indicates that the engine ECM has initiated an engine shutdown or that the engine ECM has detected an engine overspeed condition. This lamp may also indicate that an active diagnostic code is present or that an active event is present. The information is received from the engine ECM through the CAT Data Link. The information may also be received from a switch input.
Overcrank (Red Lamp)
After cranking, this lamp lights in order to indicate that the engine did not start. The lamp will also light in order to indicate that the engine did not start after normal 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. Then, the Overcrank fault indicator is flashed. Another attempt to start the engine cannot be made without placing the Engine Control Switch (ECS) in the OFF/RESET position first. The information is received from the engine ECM through the CAT Data Link.
Not In AUTO (Amber Lamp)
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.
Low Oil Pressure (Red Lamp)
This lamp indicates that the engine oil pressure is low.
Note: The default value of the trip point is programmed in the factory. A map of minimum oil pressure versus the engine speed is used to calculate the default value. This value cannot be reprogrammed. The information is received from the engine ECM through the CAT Data Link.
High Coolant Temperature (Red Lamp)
This lamp indicates high engine coolant temperature. The information may be received from the input of a High Coolant Temperature switch. The information may also be received from the engine ECM through the CAT Data Link.
Low Coolant Temperature (Amber Lamp)
This lamp indicates that the engine coolant temperature is low. The information is received from the engine ECM through the CAT Data Link. The information may also be received through the Engine Coolant Temperature sensor.
Low Coolant Level (Red Lamp)
This lamp indicates that the engine coolant level is low. The customer supplied engine coolant level sensor is no longer submerged in coolant. The information is received from the input of a Low Coolant Switch.
Local Control Enable (Amber Lamp)
This lamp indicates that the engine has been enabled locally.
Customer Defined Switch Input 1 (Amber Lamp)
This lamp is an input that is defined by the customer. The information is received from a switch input.
Customer Defined Switch Input 2 (Amber Lamp)
This lamp is an input that is defined by the customer. The information is received from a switch input.
