System Schematic For Alarm Module (ALM)There are several possible causes when the indicators of the alarm module are flashing. Before performing the test procedure, review the following requirements for the alarm module .
Check The GSC+ For Diagnostic Codes. If a CID 333 FMI 03 or CID 333 FMI 04 diagnostic code is active or if the codes are contained in the fault log, perform those procedures first.
Verify The Number Of Modules. A maximum of three modules can be connected to the GSC+ data link for the alarms.
Verify That All Remote Modules Are Powered. If multiple modules are connected to a GSC+, ALL of the modules must be powered up. If a module is not powered and the +battery wire is disconnected or if the ground wire is disconnected, the wire on terminal 2 must be disconnected as well.
Verify The Length Of The Wire. The maximum length of the wires between the GSC+ and a remote annunciator is 304 m (1000 ft). Note: The actual length of the wire can be considerably longer than the physical distance between the two modules.
Check The Type Of Wire Or Cable On The Remote Modules. Three separate wires for the following connections are recommended for remote installations: +batterybattery negativedata for the alarm. Other wires for the switched inputs on a remote annunciator may also be required by the application. The wires should be size 16 AWG. Verify that the wire is NOT a shielded type. Verify that the wire does not have twisted conductors. This type of cable is not appropriate for this purpose. These types of cables usually have more capacitance than separate wires and the data from the GSC+ can be corrupted.
Verify The Methods Of Wiring. Each remote annunciator must have a separate set of three wires between it and the GSC+. Do NOT connect any wires directly between remote annunciators. The wires should NOT be in the same conduit as wires for AC voltage or other high voltage signals. Test Step 1. CHECK THE DATA CIRCUIT WIRE FOR AN OPEN
Clear the GSC+ Fault Log. See Systems Operation, "Fault Log Clearing OP4".
Turn the engine control switch (ECS) to OFF/RESET.
Temporarily connect terminal 1 to terminal 2 of the alarm module for a few seconds.
Temporarily connect terminal 7 to terminal 2 of the alarm module for a few seconds.Expected Result:The CID 333 FMI 03 and CID 333 FMI 04 diagnostic codes should be temporarily active while the faults are occurring. The CID 333 FMI 03 and CID 333 FMI 04 diagnostic codes should be contained in the GSC+ fault log.Results:
OK - The diagnostic codes occur and the codes are contained in the GSC+ fault log. The GSC+ and the wire for the alarm (data) have not failed. Proceed to Test Step 2.
NOT OK - The diagnostic codes do NOT occur and the codes are not in the GSC+ fault log. The wire from contact 35 of the GSC+ to terminal 2 of the alarm module is open or the wire has failed. Also, the GSC+ may have failed. Proceed to Test Step 3.Test Step 2. CHECK THE ALARM MODULE FOR FAULTS.
The indicators on the alarm module remain flashing.
Disconnect the wire on terminal 2 of the alarm module.
Measure the DC voltage from terminal 2 to terminal 7 of the alarm module.Expected Result:The voltage should be 10.5 1.0 DCV.Results:
OK - The voltage is 10.5 1.0 DCV. The requirements for the alarm module that were listed at the beginning of this procedure may not be met. Repair: Review the list of requirements at the beginning of this procedure. If all requirements are being met, replace the alarm module. If the problem is not solved, replace the GSC+. See Testing and Adjusting, "EMCP Electronic Control (Generator Set) - Replace". Stop.
NOT OK - The voltage is NOT 10.5 1.0 DCV. The alarm module has failed.Repair: Replace the alarm module. Stop.Test Step 3. CHECK THE GSC+ FOR DIAGNOSTIC CODES.
Install a cable probe on pin 35 of the GSC+ 40-pin connector. Ensure that the cable probe is fully seated.
Turn the ECS to the STOP position.
Temporarily connect pin 35 of the GSC+ to +battery for a few seconds.
Temporarily connect pin 35 of the GSC+ to battery negative for a few seconds.Expected Result:The CID 333 FMI 03 and CID 333 FMI 04 diagnostic codes will temporarily be active on the GSC+ display while the diagnostic codes are occurring.Results:
OK - The diagnostic codes occur. The GSC+ has not failed. The wire from GSC+ contact 35 to terminal 2 of the alarm module is open or the wire has failed.Repair: Repair the wire or replace the wire. Stop.
NOT OK - The diagnostic codes do not occur. The GSC+ may have failed.Repair: The GSC+ may have failed. It is unlikely that the GSC+ has failed. Exit this procedure and perform this entire procedure again. During the procedure, ensure that all cable probes are fully seated and ensure that the probes are making contact with the GSC+ pins. If the result is repeated, replace the GSC+. See Testing and Adjusting, "EMCP Electronic Control (Generator Set) - Replace". Stop.
