7. Once the engine starts, engine speed will increase
to 1800 rpm. The engine may hunt or change
speeds until operating speed is reached. After a
few minutes at operating speed, the Home screen
will display the mode of the unit, the engine status,
the engine RPM, and any active program
(Scheduler or Dawn to Dusk) in Auto mode.
8. Check the generator for excessive noise or
vibration and any leaking coolant, oil, or fuel before
applying loads.
9. Once the engine is running, allow it to reach
normal operating temperature turning on the outlet
breaker.
10. Switch the export outlet breaker to the ON (I)
position. Then add any loads attached to the
outlets. You will notice a change in engine sound
when a load is applied to the unit.
Light Operation
See Figure 3-5. The lights are turned on and off using
the PowerZone–DLA. To view the light screen, press the
↑ button three times from the Home screen.
NOTE: The lights can only be turned on and off while the
unit is running in MANUAL mode. They operate
automatically in AUTO mode.
1. Once the engine is up to temperature and running
smoothly, switch the main circuit breaker to the ON
(I) position.
To turn the light(s) on, press the Select () button. To
turn the light(s) off, press the Select () button.

NOTE: The ECOSpeed engine will automatically run at
low speed when the lights are turned on. Engine speed
will remain at 1800 rpm if auxiliary equipment is
connected to the 120VAC or 240VAC customer outlets.
Engine Derating
All units are subject to derating for altitude and
temperature. Derating reduces the available power for
operating tools and accessories connected to the outlets.
For every increase in 1000 ft (305 m) of elevation, engine
performance for this unit typically drops between 2% and
4%. Also, engine performance decreases about 1% for
every 10ºF (5.6ºC) increase in ambient air temperature
over 72ºF (22ºC).
Wet Stacking
The ECOSpeed engine in this unit eliminates the adverse
effects of “wet stacking” caused by prolonged operation
of a cold, lightly-loaded diesel engine. These include:
• fuel dilution
• sooting with heavy, black exhaust
• moisture accumulation
Engine temperature and speed are continuously
managed to avoid developing a wet stack condition.
Dusk to Dawn Sensor
This unit is equipped with a “dusk to dawn” photo sensor
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 PowerZone–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 Outlets
See Figure 3-6. The unit is equipped with convenience
outlets for powering accessories or tools from the
generator. Power is supplied to the outlets any time the
engine is running and the 240VAC outlet breaker is
switched to the ON (I) position. Each outlet has an
individual circuit breaker, located on the control box.
Refer to Control Panel.
