EMCP3 Caterpillar

1. The EMCP 3 uses relay outputs to control the starting and stopping of the engine.

2. The EMCP 3 uses analog resistive sender inputs to monitor critical engine parameters.

Reference: For EMCP 3 configuration settings that are specific to MUI engine applications, refer to Testing and Adjusting, "Electronic Control Module (Generator Set) - Configure", "Set Point Tables".

MUI engine start/stop control by EMCP 3

• Relay output 1 is used to energize the starter motor magnetic switch that is used to crank the engine.

• Relay output 2 gives run signal to engine governor.

• Additional relay output can be configured for "rated speed") gives permissive signal to engine governor to ramp up to rated speed.

Note: Relay output 1 and 2 cannot be configured.

The follow is a list of MUI engine parameters that are monitored by the EMCP 3:

• Engine speed (via MPU input)

• Oil pressure (via analog input 1)

• Coolant temperature (via analog input 2)

• Spare input (only EMCP 3.3 and EMCP 3.2)
