SEAL-O-RING 6V9769 - Caterpillar

Conditions Which Generate This Code:A portion of memory within the GSC stores the setpoints of important generator set conditions. The setpoints are listed below.
engine/generator setpoint programming OP5
spare input/output programming OP6
voltmeter/ammeter programming OP8The GSC detects a CID 0268 FMI 02 when the setpoint data is invalid or the setpoint data is out of range. After detecting a CID 0268 FMI 02, the GSC sets the affected setpoints to the default value. For more information regarding setpoints and default values, see the topics that are listed below.
Systems Operation, "Engine/Generator Programming OP5"

Systems Operation, "Voltmeter/Ammeter Programming OP8"The possible cause of a CID 0268 FMI 02 is electrical interference.This procedure is designed to correct an active CID 0268 FMI 02 or the procedure is designed to correct an inactive CID 0268 FMI 02. Clear the diagnostic code from the fault log after troubleshooting is complete.The GSC treats a CID 0268 FMI 02 as an alarm fault or the GSC treats a CID 0268 FMI 02 as a shutdown fault. The treatment depends on the particular setpoint with bad data. The ring gear teeth P09 setpoint and the engine overspeed P10 setpoints are treated as shutdown faults when the particular data is corrupted. All other setpoints are treated as alarm faults when the particular data is corrupted.Note: Verify that the contact 6 to contact 9 jumper is NOT installed on the engine control switch (ECS). The contacts 6 to 9 jumper must be temporarily installed if the indicator for the shutdown fault is FLASHING. The GSC setpoints must be programmed in the OFF/RESET position when a shutdown fault is active. If the alarm for the fault indicator is FLASHING the GSC can be programmed with the ECS in the OFF/RESET position or the COOLDOWN/STOP position.Test Step 1. CHECK THE SETPOINTS.
View the setpoints that are stored in the memory of the GSC. See Systems Operation, "Engine/Generator Setpoint Viewing OP2".
Also check Systems Operation, "Spare Input/Output Programming (OP6)" and Systems Operation, "Voltmeter/Ammeter Programming (OP8)".
Compare the stored setpoints to the specified setpoints of the particular generator set.Expected Result:The stored setpoints and the specified setpoints should match.Results:
OK - All the setpoints match. Start the engine. Check the upper display for a CID 0268 FMI 02. If the diagnostic code was inactive prior to performing this procedure, then these steps should have corrected the problem.Repair: If the diagnostic code remains active, The GSC may have failed. It is unlikely that the GSC has failed. Exit this procedure and perform this entire procedure again. If the problem remains, replace the GSC. See Testing And Adjusting, "EMCP Electronic Control (Generator Set) - Replace". Stop.
NOT OK - One or more of the setpoints do not match. Repair: Program the setpoints. See the following sections.
