Manually Starting Unit in Low
Speed
STOP mode is the default start-up setting for all units
equipped with the PowerZone–DLA. Use the following
procedure to start the generator in MANUAL mode.
1. Check that the 240VAC outlet breaker is in the
OFF (O) position.
2. Move the Control Power switch to the ON (I)
position.
3. Verify that the Load Sense switch is OFF.
4. 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.
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.
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.
NOTE: UR units only—engine will attempt five 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. The engine may hunt or change speeds until low
operating speed (1350 rpm) 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, turn ON (I) both the
outlet breaker and Load Sense Switch to allow
engine to run at high speed when load is applied to
the unit.
Owner's Manual for MLT4060MVD Light Tower
Manually Starting Unit in High
Speed
At ambient temperatures below 30°F (-1°C), it may be
desirable to start at high speed to reduce crank attempts.
1. Switch the 240VAC outlet breaker to the ON (I)
position.
2. Follow steps 2 through 6 from

Light Operation

See Figure 3-6. 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.

Engine Derating

All units are affected by derating for altitude and
temperature. Derating reduces the available power for
operating tools and accessories connected to the
receptacles. Typical reductions in performance are 2-4%
for every 1000 ft (305 m) of elevation and 1% per 10ºF
(5.6ºC) increase in ambient air temperature over 72ºF
(22ºC).
