OPERATION
Figure 3.1. Basic Projector and Related Components
Projector components are briefly described and listed in alphabetical order below:
Air Filter
Intake air flows through the filter before circulating in the front compartment to cool
the main electronics. Replace the air filter whenever the lamp is replaced—or sooner
in dusty/dirty environments. Check condition monthly. See 6.4, Replacing the Lamp
& Filter for complete instructions.
Ballast Breaker (on/off)
The breaker on the lamp ballast serves two purposes: 1) it is a power switch for the
Roadie 25K ballast 2) it protects against over-current conditions of 50A or more. The
breaker must be ON in order to enable normal Roadie 25K system power-up and
operation. If faulty or major excessive AC is detected, the breaker will "trip" to OFF
in order to prevent damage. Try moving the breaker ON again—if the breaker
continues to trip OFF, this indicates a major fault and the AC problem must be
resolved. Possible causes might include shorts, damage to lamp cables, or very
excessive AC.
NOTE: This switch does not power up the projector or start the lamp. You must press
(POWER) on the keypad.
The ballast's internal fan indicates whether or not the breaker/switch is on. There is
no other indicator. Lights on the ballast indicate only that the ballast is plugged in.
