Shutter Motor
The shutter motor is located in the lamp head on the side with the shutter
drive chain. We recommend checking the power and signals from the
switch and to the motor coil, before entering the lamp head. These items
are covered in the preceding sections. Changing the shutter motor requires
a P h illips screw driver and a
3

32
" Allen wrench.
•
Remove the glass and outer reflector from the light head.
•
Open the end of the light head, where the drive chain and the sprocket
are located.
•
There are four screws that hold the motor; two of them require access
through holes in the sprocket. The shutter can be turned counterclockwise
to access these screws, by pushing the brake on the motor.
!
C
Turn the shutter only counterclockwise (looking from the
motor end) or you may damage the shutter switch on the other
end of the light.
•
Remove the chain from the sprocket with care to keep tension. The chain
has shortened links and will separate if slackened. If the chain opens,
attach an end to the sprocket with tape or wire and revolve the shutter.
•
Remove the motor sprocket by loosening the set screw.
•
Remove the two wire nuts from the motor coil wires.
•
Remove the four motor screws.
Installing the Motor
•
Mount the motor with four screws.

Install the chain on the sprockets.

The shutter can be tested with the unit open by disconnecting one of the
lamp leads and holding the interlock switch.

DO NOT light the lamp without the safety glass or when
you are close to the bulb.
