Replacing a Driver Board

Warnings: Disconnect power before servicing.
Equipment surfaces may reach temperatures up to 130° C (266° F).
Allow the fixture to cool before handling.
The DL.1 fixture is designed with two basic types of motor driver boards:
• One 2-phase board drives the motors for the focus/zoom/dimming iris
functions.
• Interchangeable 3-phase pan and tilt driver boards. Addressing screw
placement determines whether the board has pan or tilt driver functionality.
In addition, the DL.1 fixture has a CPU board located inside the fixture chassis with
the 3-phase board. Figure 5-5 shows the location of the driver boards and landmarks
you can use to locate functional areas (and LEDs) on the boards themselves:
Caution: The fixture will not function correctly if adressing screws are
missing from driver boards. Figure 5-5 identifies screw locations
on each board.
When changing a board, align the screw holes and standoffs to ensure correct
orientation in the fixture.
