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
that detects the light level, automatically starting the
engine and turning on the lights at dusk. The engine runs
and the lights are 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. Loosen (do not remove) screws securing Night
Watchman shield. Completely lower the shield.
2. Switch PowerZone controller to ON. Set unit to
AUTO mode.
3. On the controller, access the Dusk to Dawn screen.
4. On the Dusk to Dawn screen, verify setting is ON.
5. Slowly raise the Night Watchman shield, stopping
when either of the following occurs.
•
Controller indicates unit wants to start
•
An audible alarm sounds
6. Tighten screws loosened in step 1.
7. Allow unit to start. Verify lights are on. Adjust
settings as necessary.
8. Stop engine.
9. Leave controller ON. Verify unit is in AUTO mode
(as indicated by a lighted amber LED).
Fuel Level Warning Beacon
An internal fuel level sensor detects the usable amount of
fuel in the tank. When the fuel level drops to 10% or
below of maximum usable fuel capacity, the fuel level
warning beacon illuminates and flashes. The beacon will
remain illuminated until the fuel level is raised to at least
15% of maximum usable fuel capacity.
Customer Convenience Outlets
See Figure 3-7 . 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 .
See Figure 3-7 . The circuit breakers are labeled with the
corresponding voltage for the receptacle they protect.
The standard receptacle panel is equipped with the
following receptacles:
•
One 240V/30A Twist-lock (A)
(or RV receptacle, if equipped)
•
Two 120V/20A GFCI (B)
With all of the lights OFF, full generator power output is
available to the receptacles.
Figure 3-7. Location of Receptacles
NOTE: All equipment or load panels connected to the
generator MUST be properly grounded. If these
appliances do not have grounded plugs, a ground wire
MUST be added between the equipment and the
grounding stud on the receptacle panel per the National
Electrical Code (NEC), state and local regulations.
Shutting Down the Unit
Check with personnel using power supplied by the unit
and let them know the power is going to 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 outlets.
2. Switch the lights off using the controller.
3. Switch the outlet breaker to the OFF (O) position.
4. Press the Stop (O) button.
