TROUBLESHOOTING USING DVR FAULT CODES Continued
CORRECTIVE ACTION - Continued
STEP 7.
Fault code could have been caused by a fault of the load.
a. If problem recurs and fault can not be traced to load, replace DVR
b. If the problem is not resolved, refer to generator repair (WP 0096) or
replacement (WP 0097).
STEP 8.
Verify the problem is resolved.
NOTE
The DVR detected that the generator voltage has been less than the undervoltage trip point
(parameter :13) for more than the amount of time specified by the undervoltage trip time
(parameter :14). This alarm is disabled during the start-up profile.

Code 701
MALFUNCTION
Undervoltage
CORRECTIVE ACTION
STEP 1.
Adjust VOLTAGE adjust potentiometer on control panel clockwise to increase
voltage.
STEP 2.
If paralleled to other generator sets, check VOLTAGE adjust setting on each set.
STEP 3.
Start generator set and verify that problem has been resolved.
STEP 4.
If problem is not resolved, perform voltage rheostat test (WP 0040).
STEP 5.
Measure battery voltage at B+ and B- terminals on DVR per FO-4, sheet 3.
Voltage should be 18 to 32 Vdc.
STEP 6.
Verify that correct DVR parameters are entered (WP 0085) and that parameters
match the reconnection board position (WP 0012). Enter proper parameters
STEP 7.
With generator set running, measure AC voltage between pins A3-26 and A3-28,
A3-28 and A3-30, and A3-26 and A3-30 per FO-4, sheet 3.
STEP 8.
If voltages are not between 95 to 120 Vac at all three locations, shut down
generator set.
