ADAPTER GP-OIL LINE 1910523 - Caterpillar

Operation Description:The generator over current warning occurs due one of the following:
The EMCP 3 detects an over-current condition that persists for a duration that is a function of the over-current level.
A condition exceeds a threshold for a programmed durationIf the RMS current of any phase goes above the "Generator Definite Time Over Current (Amp) Percentage Threshold", then the following will occur:
A timer is started
Generator over current event is made activeThe tripping time for generator over current detection is determined from the phase with the highest current and is the smaller of the following two values:
Curve time
Set point value for generator definite time over current (amp) shutdown event notification delay timeIf an over-current condition is detected, then "GEN OVER CURRENT SHUTDOWN" or "GEN OVERCURRENT " will be displayed on the EMCP 3. The message is used to inform the operator of an over-current condition.Note: The severity of the over-current condition will determine if a warning or shutdown event occurs.The code for generator over current is generated when the EMCP 3 determines that a generator over current condition has occurred.Test Step 1. TALK TO THE OPERATOR.
Determine the conditions that caused the over-current condition.Expected Result:An over-current was caused by an occurrence known to the operator and the operator would like to put the generator set back into service.Results:
OK - The operator can determine the cause for the over-current condition. The condition has been repaired, and the operator wants to put the generator set back into service.Repair: Reset the generator set. Resume normal operation and verify that the problem has been corrected.STOP
NOT OK - The over current condition was not caused by an occurrence known to the operator. Proceed to Test Step 2.Test Step 2. CHECK THE SET POINTS.
View the following set points and make a note of the set points.
Generator current transformer primary winding rating
Generator current transformer secondary winding rating
All of the over-current set pointsRefer to Testing and Adjusting, RENR7902, "Electronic Control Module (Generator Set) - Configure". Compare the set points against the default set points of the particular generator set.Expected Result:The set points are correct.Results:
OK - The set points are correct for your particular generator set.Repair: Reset the generator set. Resume normal operation and verify that the problem has been corrected.STOP
NOT OK - The set points are NOT correct.Repair: Change the set points as needed. Reset the generator set. Resume normal operation and verify that the problem has been corrected.STOP
