5.
If the engine does not start after the first cranking
attempt, the engine will pause for 15 seconds to
allow the starter to cool. The controller backlight
will go out. The engine will make two more
attempts to start for a total of three crank cycles.
6.
If the engine does not start and run within three
starting cycles, the LCD screen will display the
“Fail to Start” alarm. The starting sequence can be
repeated after the starter cools for at least two
minutes. Pressing the Stop (O) button will clear the
alarm and reset the controller.
7.
Once the engine starts, engine speed increases to
1,800 rpm. The engine may hunt or change speeds
until operating speed is reached. After a few min-
utes at operating speed, the Home screen displays
the mode of the unit, the engine status, the engine
rpm, and any active program (Scheduler or Dawn
to Dusk) in Auto mode.
8.
Inspect 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 before
turning on the
outlet breaker.
10.
Switch the export outlet breaker to ON (I). Add any
loads attached to the outlets. Engine sound will
change when a load is applied to the unit.

NOTE:
The ECOSpeed engine will automatically run at
low speed when the lights are turned on. Engine speed
will remain at 1,800 rpm if auxiliary equipment is
connected to the 120VAC or 240VAC customer outlets.
Engine Derating
All units are subject to derating for altitude and tempera-
ture. Derating reduces the available power for operating
tools and accessories connected to the outlets. For every
increase in 1,000 ft (305 m) of elevation, engine perfor-
mance for this unit typically drops between 2–4%. Engine
performance decreases about 1% for every 10 ºF (5.6
ºC) increase in ambient air temperature over 72 ºF (22
ºC).
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 man-
aged to avoid developing a wet stack condition.
