Complete engine analog instrumentation includes DC
ammeter, oil pressure gauge, water temp. gauge, fuel level
gauge, tachometer/hour meter, manual engine speed
control, and emergency shutdown monitors.
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.
Low coolant level shutdown system provides
protection from critically low coolant levels. Includes
control panel warning light.
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.
Seven stage powder coat paint provides durability and
weather protection
EPA emissions certified - Tier 3 emissions compliant.
