Troubleshooting

Chapter

Voltage output is less than setpoint

AVR not selected/enabled

Check excitation enable (hardware
and software) and AVR select

Correct Logix controller logic or I/O
as required

Wiring error

Check wiring for excitation enable,
excitation current output, VT inputs,
fuses open, grounding, and
PMG/supply

Correct wiring as required

Insufficient supply power

Measure Voltage at CGCM-DLR unit
PMG/supply input terminals

Correct supply anomaly if
insufficient voltage is measured

Measure generator residual voltage
(shunt excitation)

If less than 10V AC, consult
generator manufacturer
documentation and update the
generator field

Generator not up to rated speed

Check generator speed

Increase generator speed to rated
speed

Correct condition preventing rated
speed from being attained

Field resistance too great

Disconnect field current outputs at
CGCM-DLR unit and measure load
resistance

Correct/verify load resistance is
within CGCM-DLR unit capability

Gain mis-adjusted

Check gains that are entered into
CGCM-DLR unit configuration

Calculate/adjust as required

Excitation limiting active

Check OEL active input

Correct OEL configuration or change
operating point

Droop compensation is driving down
the voltage

Check Droop Enable

Adjust/disable droop compensation
