normal operating temperature before switching on
any loads.
Automatic Shutdown
This unit is equipped with a low oil pressure and high
coolant temperature automatic shutdown system. This
system will automatically shut 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 the OFF position to reset the unit after
the cause of shutdown has been determined.
Light Operation
1. Verify the unit is on and running smoothly.
2. See
. Switch the main circuit breaker (A)
ON (I).
3. Switch the individual circuit breakers for the lights
(B) ON (I), one at a time.
4. The ballast indicator lights (C) will turn on and
continue to get brighter as the lights warm up, and
then remain on. This confirms power is coming
from the ballasts to the lights.
Figure 3-7. Light Switches and Breaker
NOTE:
If an indicator light does not turn on, see
or contact a Generac Mobile Products
Authorized Service Dealer.
NOTE:
The lights require a warm up period of 5-15
minutes before they reach full output. If the lights are shut
down, they require a cool down period of approximately
ten minutes before they can be switched on again.
NOTE:
The light tower uses four 1000W or 1050W
bulbs. When checking or replacing the bulbs, wipe them
with a clean cloth to avoid leaving any grease, oil residue
or fingerprints on the glass. Any residue can create a hot
spot on the bulb, causing premature bulb failure.
