Operation
Battery
The installer must supply a valve-regulated, rechargeable
12 volt DC starting battery. See Battery in Final Installation
Considerations in the installation manual.
With the battery installed, all wiring to transfer switch and
generator completed, utility power supplied to the automatic
transfer switch, and the unit in AUTO mode, the battery
receives a trickle charge while the engine is not running. The
trickle charge cannot be used to recharge a battery that is
completely discharged.
15 Amp Fuse
The generator’s 15 Amp fuse is critical to correct system
operation. Your installer will ensure the fuse is properly
installed upon completion of the installation.
Engine Oil
The engine is shipped from the factory pre-run and filled
with synthetic oil (API SJ/CF 5W-30). This allows for system
operation in a wide range of temperature and climate
conditions. Before starting the engine, check oil level
and ensure that engine is serviced as described in the
Maintenance section.
Coolant System
This engine is shipped from the factory filled with a 50-50 mix
of automotive (Ethylene glycol) anti-freeze and water. This
will provide optimum year round protection against freezing,
boiling and corrosion. The coolant system incorporates
an optional water heater that operates when ambient
temperature is below 80ºF AND utility power is present at
the transfer switch. Before starting the engine, check coolant
level as described in the Maintenance section
Important Owner’s Considerations
WARNING Battery posts, terminals and related accessories
contain lead and lead compounds, chemicals known to the State
of California to cause cancer and reproductive harm. Wash
hands after handling.
The generator’s control board constantly monitors utility
voltage. Should utility voltage drop below a preset level, the
control board will signal the engine to crank and start.
When utility voltage is restored above a preset voltage level,
the engine is signaled to shut down.
The actual system operation is not adjustable and is
sequenced by sensors and timers on the control board,
as follows:
Utility Voltage Dropout Sensor
• This sensor monitors utility source voltage.
• If utility source voltage drops below about 70 percent
of the nominal supply voltage, the sensor energizes
a 3 second timer. The timer is used to ‘sense’
brown-outs.
• Once the timer has expired, the engine will crank
and start.
Automatic Operation
NOTICE Any attempt to crank or start the engine before it has
been properly serviced with the recommended oil will result in
equipment failure.
• Refer to Maintenance section for coolant and oil fill information.
• Damage to equipment resulting from failure to follow this
instruction will void engine and generator warranty.
Utility Voltage Pickup Sensor
This sensor monitors utility voltage. When utility voltage is
restored above 80 percent of the nominal source voltage,
a time delay starts timing and the engine will go to engine
cool-down.
Engine Cool‑down Timer
When utility power is sensed and the load transfers back to
the utility source, the engine will go into a cool down period
as described below:
• If the generator has run for MORE than 5 minutes,
once the utility transfer occurs, the engine will
continue to run for about 1 minute before shutting
down.
• If the generator has run for LESS than 5 minutes, once
the utility transfer occurs, the engine will continue to
run until 5 minutes has elapsed before shutting down.
