5-6 General Maintenance and Troubleshooting DL.1 User Manual

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 5-5-5 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 5-5-5 identifies screw

locations on each board.

When changing a board, align the screw holes and standoffs to ensure correct

orientation in the fixture.
