Ruud Generator Systems, GEN12AD-V manual Uction

To remedy the low oil pressure condition, add the recommended oil to the FULL mark on the dipstick.

If the low oil pressure condition still exists, the engine will start, then shut down again. The fault code will appear and the LED will flash. In this case, contact an authorized dealer.

Reset Fault Detection System

The operator must reset the fault detection system each time it activates. To do so, place the control panel system switch in the OFF position for 30 seconds or more. Remedy the fault condition, then return the generator to service by placing the system switch in the AUTO position, installing the 15 Amp fuse, and resetting the exercise timer. See Setting Exercise Timer in Operation.

Low Voltage (Generator, FC_3)

This fault is indicated by fault code FC_3 and three blinks on the remote LED indicator. This condition is caused by a restriction in the fuel flow, a broken or disconnected signal lead, a failed alternator winding, the control panel circuit breaker is open, or the generator is overloaded.

To remedy the problem, contact your installer or an authorized dealer.
