Operation

Dusk to Dawn Sensor

This unit is equipped with a "dusk to dawn" photo sensor
to detect the surrounding light level, to automatically start
the engine and turn the lights on at dusk. The engine will
run and the lights will remain illuminated until dawn.
To prepare the sensor for use, proceed as follows at the
time of day desired for the lights to turn on:
1. Verify the Power Zone–DLA is set up and the unit
is ON.
2. Slide the light shield bracket up, decreasing the
sensor's exposure to light, until the lights turn ON.
3. Tighten screws on shield.
Customer Convenience Recepta-
cles
See Figure 3-6. The unit is equipped with convenience
receptacles for powering accessories or tools from the
generator. Power is supplied to the outlets any time the
engine is running and the 240VAC/30A main breaker is
switched to ON (I). Each receptacle has an individual
circuit breaker, located on the control panel. Refer to
Control Panel.
A
Figure 3-6. Convenience Receptacles
See Figure 3-6. The circuit breakers are labeled with the
corresponding voltage for the receptacle they protect.
The standard control panel is equipped with the following
receptacles:
• One 240VAC/30A Twist-lock (A)
•
One 120V/20A GFCI (B)
NOTE: Do not pull more than a combined total of
4,800W from the receptacles with the lights on. This will
overload the generator and cause the main circuit
breaker to trip. Should the breaker trip, switch off the
lights, remove some of the loads connected to the
receptacles.
With all of the lights off, the full generator output may be
used with the 240VAC/30A twist-lock receptacle.

Shutting Down the Unit

IMPORTANT NOTE: Verify with personnel using
power supplied by the unit and notify them power
will be turned off. Verify the power shutdown will not
create any hazards by accidentally turning off equip-
ment that needs to remain running (pumps, compres-
sors, lights, etc.).
1. Remove all loads from the receptacles.
2. Switch the lights off using the controller.
3. Set the outlet breaker to OFF (O).
4. Press the Stop (O) button.
5. Set the control power switch to OFF (O) after the
unit shuts down.
NOTE: Disconnect the battery if the unit is to be stored
for an extended period. Refer to the engine operator's
manual for additional extended storage procedures.

Automatic Shutdown

This unit is equipped with a low oil pressure and high
coolant temperature automatic shutdown system. This
system will automatically shut off the fuel supply to stop
the engine if oil pressure drops too low or the engine
exceeds normal operating temperature. Return the
control power switch to STOP to reset the unit after the
cause of shutdown has been determined.
Lower Radiator Hose Heater (If
Equipped)

Use and Maintenance

The lower radiator hose heater is designed to prevent
engine coolant from freezing in extreme cold weather
conditions. While the heater is designed to be operated
overnight if necessary, 2–5 hours of heating just prior to
starting is usually sufficient for proper engine starting.
NOTE: Use the lower radiator hose heater only in its
designated location. Incorrect use can damage the
engine.
Proceed as follows when operating a unit equipped with
a lower radiator hose heater.
1. Verify the unit is level to maintain correct orienta-
tion of the heater while it is in operation.
2. Verify the cooling system is full of the correct mix-
ture of water and engine coolant before each
heater use.
3. Use only an undamaged, outdoor rated, three-
prong grounded 120VAC extension cord with a
minimum amperage rating of 10A. Connect the
cord to a properly grounded 120VAC, GFCI outlet.
