frequency to within ± 0.25% from no load to full load.
- Fuel/water separator removes condensation from fuel for
extended engine life. Panel mounted alarm light included.
- Complete engine analog instrumentation includes DC
ammeter, oil pressure gauge, water temp. gauge, fuel level
gauge, tachometer/hour meter, preheat indicator, and
emergency shutdown monitors.
- Complete generator analog instrumentation includes
voltage regulator control, ammeter 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.
- Automatic start/stop control — automatically starts the
generator set during a commercial power failure when used
in conjunction with a transfer switch.
- Complete power panel. Fully covered; single-phase
terminals and single phase receptacles allow fast and
