Complete engine analog instrumentation includes DC
ammeter, oil pressure gauge, water temp. gauge,
tachometer/hour meter, preheat indicator, manual engine
speed control, emergency shutdown monitors, and
emergency stop button.
Complete generator analog instrumentation includes
voltage regulator control, ammeter phase selector switch,
voltmeter phase selector switch, AC voltmeter, AC
ammeter, frequency meter, panel light, and circuit breaker.
Automatic safety shutdown system monitors the water
temperature, engine oil pressure, overspeed, and
overcrank. Warning lights indicate abnormal conditions.
Auto start/stop control allows generator to start
automatically in the event of a commercial power failure.
Complete power panel. Fully covered; three-phase
terminals and single phase receptacles allow fast and
convenient hookup for most applications including
temporary power boxes, tools and lighting equipment. All
are NEMA standard.
Simultaneous single and three phase power.
