Notice: Features and equipment specifications are subject to change without notice.
Standard Features:
- Heavy duty, 4-cycle, direct injection, diesel engine provides
maximum reliability.
- Brushless alternator reduces service and maintenance
requirements and meets temperature rise standards for Class
H insulation systems.
- Open delta excitation design provides virtually unlimited
excitation for maximum motor starting capability.
- Automatic voltage regulator (AVR) provides precise regulation.
- Electronic Governor Control (Crystal Sync) — maintains
frequency to within ±0.25% from no load to full load.
- Full load acceptance of standby nameplate rating in one step
(NFPA 110, para 5-13.2.6).
- Sound attenuated, weather resistant, steel housing provides
operation at 57 dB(A) at 23 feet. Fully lockable enclosure
allows safe unattended operation.
- Internal fuel tank with direct reading of fuel gauge.
- Seven stage powder coat paint system provides durability
and weather protection.
- 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, emergency
shutdown monitors.
- Automatic start/stop control — automatically starts the
generator set during a commercial power failure when used
in conjunction with a transfer switch.
- 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.
- 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. The GFCI receptacles
are NEMA 5-20, and the auxilillary outputs use CS6369 twistlock
receptacles.
- Simultaneous single and three phase power.
- Voltage selector switch offers the operator a wide range of
voltages that are manually selectable. Fine tuning of the
output voltage can be accomplished by adjusting the voltage
regulator control knob to obtain the desired voltage.
- EPA emissions certified - Interim Tier 4 emissions compliant.
Optional Generator Features:
- Battery Charger — provides fully automatic and selfadjusting
charging to the generator's battery system.
- Jacket Water Heater — for easy starting in cold weather
climates.
- Special Batteries — long life batteries provide extra engine
cranking power.
- Low Coolant Level Shutdown — provides protection
from critically low coolant levels. Includes control panel
warning light.
- Spring Isolaters — provides extra vibration protection for
standby applications.
- Trailer Mounted Package — meets National Highway
Traffi c Safety Administration (NHTSA) regulations. Trailer is
equipped with electronic or surge brakes with double or triple
axle confi guration.
Optional Control Features:
- Emergency Stop Switch.
- Audible Alarm — alerts operator of abnormal conditions.
Ultra-Silent Features:
- Low Noise Muffl er — Large capacity low noise muffl er
minimizes exhaust sound.
- Soundproof Casing — The new design divides the cabinet
into three sections, separating the engine, muffl er and radiator
for more effi cient cooling and reduces noise from the engine
and fans.
- New Cooling System — An advanced design uses two
separate air intake systems to cool the generator. The engine
fan draws air in to cool the engine and generator housing while
a second electric fan directly cools the radiator. With less air
being drawn into the generator through each fan, considerably
less noise is produced through the top of the generator.
- Environmental Design — Constructed using an integrated
environmental skid and fuel tank. This design fully contains
fuel leakage and any liquid that might leak from the engine
such as lube oil or radiator coolant. All potentially hazardous
liquids are contained without contaminating the surrounding
area.
