Common problems

Shutdown indicator LED is illuminated.
Fix: Resolve by resolving shutdown condition.
Lug Door Open indicator LED is illuminated.
Fix: Resolve by closing lug-box door. If condition remains unresolved, inspect lug-box door safety switch for proper operation.
Low Load indicator LED is illuminated.
Fix: Resolve by increasing electrical load. If unable to operate genset at more than 30% load, use a smaller generator.
Indicates a fault state. The DVR stops providing excitation. FXXX
Emergency Stop indicator LED is illuminated.
Fix: Resolve by deactivating (pulling out) Emergency Stop switch.
AXXX indicates an alarm state. The DVR continues to provide excitation, if excitation is enabled.
Cause: [blank] Indicates normal operation in SLEEP mode. STBY Indicates normal operation in stand-by mode, waiting for the STRT state. STRT Indicates DVR is in a soft start state. RUN.V Indicates normal operation, with excitation in AVR mode. RUN.I Indicates normal operation, with excitation in FCR mode. RUN.P Indicates normal operation, with excitation in VAR or PF mode.
