CORRECTIVE ACTION
8. VOLTAGE RECOVER SLOW WITH LOAD CHANGE - Continued.
Step 3.
Verify that the generator frequency is stable.
If the frequency is unstable, consult with the governor manufacturer.
If the frequency is stable, proceed to step 4.
Step 4.
If the above steps fail to correct the malfunction, replace or repair the voltage regulator
as necessary.
9. PARALLEL GENERATORS DO NOT DIVIDE REAL KW LOAD EQUALLY.
Consult with the governor manufacturer for improving the power sensing of the governor and/or
adjustment of the governor droop setting.
10. NO REACTIVE DROOP COMPENSATION CAN BE OBTAINED FOR PARALLEL GENERA-
TORS.
Step 1.
Verify that the tap on R25 is not set to the minimum position.
If the tap is set to the minimum position, adjust R25 to obtain the required droop.
If the tap is set properly, proceed to step 2.
Step 2.
Verify that the Parallel CT provides the required 3 to 5 A secondary current.
If the CT does not provide the required 3 to 5 A secondary current, refer to paragraph 3-
3.
If the CT does provide the required 3 to 5 A secondary current, proceed to step 3.
Step 3.
Verify that terminals 1 and 2 of the regulator are not shorted by the UNIT/PARALLEL
switch.
If the switch is set to UNIT, set switch to PARALLEL.
If the terminals are shorted, replace the switch and/or repair the wiring.
If the terminals are shorted, proceed to step 4.
Step 4.
If the above steps fail to correct the malfunction, replace or repair the voltage regulator
as necessary.
