Operation
The switch will remain closed until it is pulled out.
Figure 3-4. Emergency Stop Switch
NOTE: Use the emergency stop switch only when the
unit must be shut down immediately. For any other shut
down, refer to
Shutting Down the
Engine Break-In Requirements
NOTE: The EPA final tier 4 Isuzu engines have an
engine break-in duration that will prohibit the unit from
providing rated standby power upon factory delivery. The
unit is tested at the factory and is initially capable of a
prime standby power output. The engine performance
will increase to 95% of full rated power during the first 20
hours of loaded operation. The unit will provide full rated
power after the complete engine break-in period of 70
hours of loaded operation.
Operate the engine at heavy loads (60-90% [24-36kW] of
rated output maximum) as much as possible during the
break-in period.If the engine has spent significant time at
idle, constant speed(s) and/or light load or if makeup oil
is required, a longer break-in period may be needed.
Refer to the engines operator's manual for a full
description of necessary procedures on the addition of oil
and extension of the break-in period. For more
information on regular maintenance intervals, refer to
Basic Maintenance
Guide.
Manually Starting the Unit
STOP mode is the default start-up setting for all units
equipped with the Power Zone–DLA. Use the following
procedure to start the generator in MANUAL mode.
1. Verify the 240VAC outlet breaker is switched OFF
(O).
2. Switch the main circuit breaker ON (I).
3. When the controller powers up, the Home screen
displays on the LCD screen and the Stop LED
illuminates to indicate that the controller is in STOP
mode. Press the Start button to initiate the startup
procedure. Assuming there are no existing engine
faults, the engine will start and the Start LED will
illuminate.

Unit.
NOTE: The engine can be started from any screen. It
may take a few seconds for the engine to run smoothly
and reach its governed operating speed.
4. 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.
5. 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.
Auto (Remote) Starting of the
Unit
Auto mode is used when the unit is started from a
location other than the control panel by using a transfer
switch. Auto (remote start) is the normal setting when the
generator is being used as a standby power supply.
Before putting the unit in the Auto mode, review the
Prestart Checklist
and
Also following any warnings and information on isolating
the generator with a transfer switch if the unit is to be
used as a standby power supply. Then continue with the
steps described below:
1. Perform a manual start of the unit at least once to
verify that the engine is operating correctly.
NOTE: The lights are automatically disconnected on
startup. The main circuit breaker can be left on if no other
loads are connected, except for the lights. Any connected
external loads must be disconnected by a transfer switch
when starting the unit.
2. If a check of the remove start circuit is desired:
a. Remove the wires from the remote start terminal
block. Press the Auto button. The Auto LED with
be lit.
b. Attach a jumper wire (minimum 16 gauge)
across the two terminals on the remote start
terminal block. This applies a ground to the
controller to close the starting circuit contacts.
The engine should crank, start and run.
c. Remove the jumper wire form the remote start
terminal block and the engine will stop.
d. Reconnect any necessary wires form the remote
start switch (transfer switch) to the remote start
terminal block.
3. Confirm the unit is in Auto mode. The Auto LED
should be lit.
4. Secure the unit by closing and locking all access
doors.
5. The unit is now ready for remote starting
