Replacing Motor Driver Boards
The DL.3 fixture is designed with two motor driver boards:
1. The board that controls the motors for the tilt, fo
cus, zoom, and iris functions as well as fans
is located in the fixture head.
2. The board that drives pan motor and fans is l
ocated in the base housing.
All cabling is marked with labels corresponding to locati
ons on board for easy replacement. When
changing a board, align the screw holes and standoffs to ensure correct orientation in the fixture.
Fixture Head Driver Board
To replace the fixture head driver board:
1. Disconnect power to
the fixture and allow it to cool.
2. Unlatch the two rear latches and
remove the rear bezel.
