Operation
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 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. If the breaker trips, switch off the lights,
remove some of the loads connected to the receptacles.
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 light circuit breaker to OFF (O).
3. Switch the main circuit breaker OFF (O).
4. Move the control power switch to STOP.
Shutting Down the Unit (Power
Zone–DLA) (If Equipped)
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. Turn the lights off using the controller.
3. Switch the main circuit breaker OFF (O).
4. Press the Stop (O) button.
5. After the unit shuts down, switch the control power
switch OFF (O).
NOTE: Disconnect the battery if the unit will 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 automatically shuts off the fuel supply to stop the
engine if oil pressure drops too low, or the engine
exceeds normal operating temperature. Return the main
circuit breaker to STOP to reset the unit after the cause
of shutdown has been determined.
Lowering the Mast—Manual
Winch
1. Shut down the lights and engine. See Shutting
Down the Unit.
2. Lower the mast.
3. Use the winch handles to collapse the mast to its
lowest position. Verify the electrical cord does not
get caught in, or pinched by, the mast while it is
being lowered.
.
IMPORTANT NOTE: Contact a GMASD immediately
if the mast hangs up or the winch cable develops
slack.
