TROUBLESHOOTING USING DVR FAULT CODES Continued
CORRECTIVE ACTION - Continued
STEP 7.
Measure AC voltage between terminals A3-5 and A3-6 of DVR per FO-4,
sheet 3. Record value.
a. The voltage measured, divided by the value in parameter :05 should be
roughly equal to the measured current divided by parameter :04.
b. If not approximately the same, replace DVR (WP 0041).
STEP 8.
Fault code could have been caused by a fault of the load.
If the problem is not resolved, refer to generator repair (WP 0096) or replacement
STEP 9.
Verify the problem is resolved.
NOTE
The DVR detected that the exciter field current was greater than approximately 28 Amps. The
DVR shut off the exciter field current.

CORRECTIVE ACTION
STEP 1.
On keypad, press ALARM CODES and check GSC related codes. Resolve as
required.
STEP 2.
Disconnect wire from DVR, A3, and Terminal F2. Measure resistance between
disconnected wire and F1.
a. If resistance is less than 4 ohms, troubleshoot exciter circuit between F1, F2,
and exciter windings (WP 0090). Repair or replace wiring harness as
necessary.
b. Test exciter windings (WP 0096). Repair or replace Generator G1 as
necessary.
c.
If resistance is 4 ohms or greater, replace DVR (WP 0041).
STEP 3.
Verify the problem is resolved.
