Operation

Wet Stacking

The unit is powered by a diesel engine. Diesel engines
are subject to "wet stacking" if lightly loaded. Wet
stacking occurs when an engine is run at less than 30%
of its full load capacity, causing unburned fuel to
accumulate in the exhaust system. Wet stacking can be
detected by continuous black exhaust when the unit is
under a constant load. It can also cause fouling of
injectors and buildup on engine valves. Diesel engines
operate properly when applied loads are between 30–
100% capacity. Appropriate
determined by the anticipated load. If the unit is in a wet
stack condition, load the unit heavily for five hours or until
the exhaust is clear.
Dusk to Dawn Sensor (Power
Zone–DLA) (If Equipped)
See Figure 3-13. If equipped with the Power Zone-DLA
controller, this unit includes
nightwatchman sensor (A) to detect the surrounding light
level, automatically starting the engine and turning the
lights on at dusk. The engine will run and the lights will
remain illuminated until dawn.
To prepare the sensor for use, perform the following
procedure at the time of day you want 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
Receptacles
See Figure 3-14. The unit is equipped with convenience
receptacles for powering accessories or tools from the
generator. Power is supplied to the receptacles any time
the engine is running and the main circuit breaker is
switched to the ON (I) position. Each receptacle has an
individual circuit breaker, located on the control box.
Refer to Control Panel.

Figure 3-14. Convenience Receptacles
The circuit breakers are labeled with the corresponding
voltage for the receptacle they protect. The standard
receptacle panel is equipped with the following recepta-
cles:
One 240V/30A Twist-lock (A)
•
One120V/20A GFCI (B)
•
NOTE: Do not draw more than 800W from each
receptacle when 1100W bulbs are equipped, 1000W
when 1050W bulbs are equipped, and 900W when
1000W bulbs are equipped. the lights are on. This will
overload the generator and cause the main circuit
breaker to trip. If the breaker trips, switch off the lights,
remove some of the loads connected to the receptacles
and wait 10 minutes for the bulbs to cool before turning
them back on.
With the lights off, the full generator output may be used
with the 240V twist-lock receptacle.

Shutting Down the Unit

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 equipment that needs to remain running
(pumps, compressors, lights, etc.).
1. Remove all loads from the receptacles.
2. Switch the individual circuit breakers for each light
OFF (O).
3. Switch the main circuit breaker OFF (O).
4. Move the control power switch to STOP.
