TRACK GP 1963967 - Caterpillar

Operation Description:If the frequency drops below the "Generator Underfrequency Percentage Threshold" setpoint value, then the underfrequency timer will begin timing. When the timer expires, then the generator underfrequency event is made active (if the frequency has been below the threshold level continuously while timing). If the frequency rises above the generator underfrequency percentage threshold, then the generator underfrequency event will be made inactive and the timer will be reset.If an underfrequency condition is detected, then "GEN UNDERFREQUENCY SHUTDOWN" or "GEN UNDERFREQUENCY " will be displayed on the EMCP 4. This warning is to inform the operator of an underfrequency condition.Note: The severity of the underfrequency condition will determine if a warning or shutdown event occurs.Conditions Which Generate This Code:The code for generator underfrequency is generated when the EMCP 4 determines that a generator underfrequency condition has occurred. Test Step 1. TALK TO THE OPERATOR
Determine the conditions that caused the underfrequency condition. Expected Result:An underfrequency condition was caused by an occurrence that is known to the operator. The operator would like to place the generator set back into service.Results:
OK - The operator can determine the cause for the underfrequency condition. The condition has been repaired, and the operator wants to put the genset back into service.Repair: Reset the genset. Resume normal operation and verify that the problem has been corrected.The genset operates normally.
NOT OK - The underfrequency condition was not caused by an occurrence known to the operator. Proceed to Test Step 2Test Step 2. CHECK THE SETPOINTS
View the "Generator Underfrequency" and "Generator Desired Engine Speed Request" setpoints. Make a note of the setpoints. Refer to Testing and Adjusting, "Electronic Control Module (Generator Set) - Configure". Compare the setpoints against the default setpoints of the particular generator set. Expected Result:The setpoints are correct.Results:
OK - The setpoints are correct for your particular genset. Proceed to Test Step 3 for EUI Engines. Proceed to Test Step 4 for MUI engines
NOT OK - The setpoints are NOT correct.Repair: Reprogram the setpoints. Reset the genset. Resume normal operation and verify that the problem has been corrected.STOPTest Step 3. VERIFY FREQUENCY CAN BE VIEWED AND ADJUSTED FROM THE EMCP 4 (EUI ENGINES ONLY)Verify that the generator output
