TP-5353 8/94 Generator/Controller Troubleshooting 6-9
FASTCHECK
â
Features and Operation
The FASTCHECK
â
is an engine simulator for testing
and troubleshooting the microprocessor controller.
Features
Features are shown in the following paragraphs, see
Figure 6-8 for illustration. Engine conditions are
simulated by the following engine switch position:
D OFF—locked engine (starter energized but not
turning)
D CRANK—engine cranking, but not started
D RUN—engine running
Indicator Lamps
IGN—(ignition) lamp:
D shows battery voltage supplied to ignition
(gas/gasoline) or fuel solenoid (diesel), fuel valves,
water valve (city-water cooled sets)
D lights during cranking and running
CRK—(crank) lamp:
D shows battery voltage switched to starter (engine
not necessarily turning)
D lights only during on-crank cycles
REG—(regulator) lamp:
D shows battery voltage supplied to generator set’s
AC voltage regulator
D lights only during cranking and running
BATT—(battery) lamp:
D shows lights when test battery(ies) or DC power
supply is live and properly connected
NOTE
L.O.P., H.W.T., and OVERSPEED simulate
malfunctions causing engine to shut down. L.O.P and
H.W.T. circuits will start timing after engine has been
running for 30 seconds. Engine shutdown should occur
5 seconds after pushing fault switch.
