GASKET-CAP 2A1763 - Caterpillar

Verify that the potential transformers are installed correctly.
Is there a difference between sensed voltage and rated voltage? That is, does a difference exist from the voltage that is sensed off the wye center tap to the rated voltage? OK - If yes, go to Step 4.NOT OK - If no, go to Step 3.
Verify that the following parameters are programmed as follows:
The Rated voltage (V) equals the generator rated voltage
The PT primary (V) equals the generator rated voltage
The PT secondary (V) equals the generator rated voltageGo to step 4.
Verify that the field winding inputs to the CDVR are not partially shorted or shorted completely. OK - If winding inputs are ok, go to Step 5.NOT OK - If winding inputs not ok, repair winding input fault. Check the system again.STOP.
Check exciter for proper resistance value. OK - If exciter resistance value is ok, go to Step 6.NOT OK - If exciter resistance value is not ok, repair exciter fault. Check the system again.STOP.
If all of the previous steps fail to correct the malfunction, replace the voltage regulator. STOP.
