Programmable Relay Control Module (PRCM) Caterpillar

The Setpoint Viewing/Programming menu is entered by pressing the "MODE" button from the Fault Viewing/Clearing menu or the I/O Monitoring/Programming menu. The Setpoint Viewing/Programming menu allows the operator to view program PRCM setpoints. The Setpoint Viewing/Programming menu also allows the operator to program the PRCM setpoints.

Table 1

PRCM SETPOINTS
Setpoint Number	Setpoint Value	Description
P01	01	Genset or center marine engine.
	02	Port marine engine.
	03	Starboard marine engine.
P02	01	All outputs controlled by the ECM remain in the state required by the last valid input, if communications from the ECM are lost (CAT data link failure).
	02	All outputs controlled from the ECM are reset to OFF.
P03	01	PRCM displays CID 590 FMI 09 and CID 248 FMI 11 diagnostic codes when the diagnostic codes are active, but does NOT place the diagnostic codes in the PRCM fault log.
	02	PRCM displays CID 590 FMI 09 and CID 248 FMI 11 diagnostic codes when the codes are active and places the diagnostic codes in the fault log.

The upper display will be blank and the lower display will show "P01 0X". The "X" represents 1, 2, or 3. The 1, 2, and 3 represents the different types of engines.

In the following example, the setpoint "P01" is programmed to "02". A "02" is for the marine engine that is located on the port side.

1. The "UP" and "DOWN" buttons are used in order to scroll through the list of setpoints.

2. To program a setpoint, press the "ENTER" button. The password must be entered before the operator is allowed to enter the programming function. Refer to Systems Operation, "Input/Output Monitoring and Programming" for detailed instructions on entering the password. After you enter the password, the setpoint number should be flashing.

3. Use the "UP" and "DOWN" buttons to obtain the desired setpoint.
