Excitation output is greater than
setpoint FCR not selected/enabled Check excitation FCR select Correct Logix controller logic or I/O
as required
Wiring error Check wiring for excitation current
output, fuses open, grounding, and
PMG/supply Correct wiring as required
Gain mis-adjusted Check gains that are entered into
CGCM-DLR unit configuration Calculate/adjust as required
Excitation is erratic/unstable Gain mis-adjusted Check gains that are entered into
CGCM-DLR unit configuration Calculate/adjust as required
Wiring error Check wiring for excitation enable,
excitation current output, fuses
open, grounding, and PMG/supply Correct wiring as required
Table 19 - Excitation Control - FCR
Symptom Most Likely Cause Diagnostic Action Corrective Action
Table 20 - Excitation Control - AVR
Symptom Most Likely Cause Diagnostic Action Corrective Action
No excitation current output Excitation is not 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
No supply/PMG power Measure Voltage at CGCM-DLR unit
PMG / supply input terminals Correct supply anomaly if
insufficient voltage is measured
