Electrical Troubleshooting Procedures LTC Repairwc_tx000429gb.fm 987.13 Checking Generator Voltage at ReceptacleSee Graphic: wc_gr003075Electric shock hazard. Only qualified personnel should conduct thistest.A quick way to check the function of the generator is to check voltageat the receptacle. If the correct voltage is present, problems with thelights not functioning will be associated with the circuit from the maincircuit breaker to the lights.Complete this test with the machine running and both the main circuitbreaker and the receptacle circuit breaker in the ON position. If yourmachine includes an earth-leakage circuit breaker, also place it in theON position.7.13.1 Using the AC voltage setting on the multimeter, test the receptacle for120V±10% on 60Hz models; 115V or 230V±10% on 50Hz models.• If zero (0) volts is measured, it indicates there may be a problemwith the generator. Before checking the generator, check thereceptacle reset button if equipped on your machine model.Depress the button if it has “popped out”. If the reset button willnot stay depressed, check the condition of the wiring to thereceptacle. See section Checking Receptacle.• If the correct voltage is measured, the generator is functioning.See the troubleshooting flowcharts for troubleshooting sequence.WARNING1000200 202200mF VAV- COM1000200 202200mF VAV- COMwc_gr003075
