FUEL SYSTEM
Either Natural Gas or LP gas can fuel the
genset. The genset is equipped with an elec-
tric fuel solenoid. The solenoid will adjust for
either fuel type with a flip of a switch. A toggle
switch on the back side of the control box
allows you to choose the desired fuel type.
Place the switch to NG for natural gas or LP
for LP gas.
Note: Fuel pressure coming into fuel shut off valve
should be adjusted to 11-14 inches of water.
BATTERY
It is recommended that a 12-volt battery with a
minimum of 450 cold cranking amps be used
for the genset. The climate will be a major
factor in deciding the appropriate battery. If
the temperature dips below 0- F for extended
lengths of time, a more powerful battery may
be necessary. Consult your local dealer/
distributor for assistance.
If the genset is not run on a regular basis, it is
recommended to use an external battery
charger to sustain full charge. Follow the
safety precautions in the beginning of this
manual when servicing the battery. Batteries
contain sulfuric acid, which can cause perma-
nent eye damage, burn skin, and eat holes in
clothing. Battery gases can cause an explo-
sion, which can cause severe injury or death.
Take extreme care when removing and replac-
ing battery terminals, reversed connections
can cause severe damage to the genset.
5. With the manual transfer handle, move the
switch’s main contact back to the utility
power position, thereby, reconnecting the
utility power supply.
6. Turn ON the utility power supply to the
Transfer Switch, using whatever means
provided (such as a utility main line circuit
breaker). The utility power source now
powers the loads.
AUTOMATIC OPERATION
To set the system for fully automatic operation,
proceed as follows:
1. Check that load circuits are connected to
the utility power supply.
2. Set the AUTO/OFF-RESET/MANUAL
switch to the AUTO position.
3. Set the generator main circuit breaker to its
ON position.
AUTOMATIC OPERATING SEQUENCE
The automatic operation is controlled by the
automatic transfer switch. For a more exact
description of automatic operating sequence,
see Transfer Switch Instruction Manual. The
sequence of automatic operation is briefly
described as follows:
1. Should the utility source drop below a
preset level, a delay timer starts.
2. After the delay time, the transfer switch
sends a signal to the engine remote con-
tacts to start.
Note: The delay timer is provided to override
momentary outages & prevent nuisance starting
of the genset.
3. The transfer switch senses the voltage of
the emergency source. When the emer-
gency source reaches a preset level, trans-
fer delay timing begins. When this time is
completed, the load circuits are transfered
to the emergency source.
4. If the utility source voltage is restored,
above the preset level, the transfer switch
monitors the voltage for a period of time.
After this time the switch retransfers load
circuits back to the utility power source.
5. After load circuits are retransfered, the
engine will go through its cool down proce-
dure before shutting down.
