WARNING!
Unexpected pan and tilt can cause injury
or damage the dome during servicing. To
prevent such movement, always
disconnect power/data connector P3
from the Unicard board before servicing.
1. Remove the lens and camera shrouds.
When removing the four screws from each shroud,
you may want to use a screwdriver with a magnetic
tip.
Note: It is not necessary to remove the eyeball
assembly to perform this task.
2. Detach cable connectors.
On the yoke bracket, unplug the receptacle
connector from the clock-spring cable; on the
Unicard board, unplug the ribbon cable from P8.
3. Remove the two screws that secure the slip-
ring receptacle.
At the base of the carriage assembly, remove the
two M3x12, Phillips head screws that secure the
receptacle.
4. Remove the slip-ring.
Cut the tie wrap and remove the old slip-ring and
washer while carefully feeding its receptacle
connector down through the slip-ring receptacle.
5. Install the slip-ring.
Insert the new slip-ring by carefully inserting its
receptacle cable connector through the receptacle
(make sure the washer stays at the end of the slip-
ring as it enters the receptacle). Position the slip-ring
ribbon cable in the slot of the receptacle and slowly
turn the slip-ring clockwise approximately 3/4-turn
until its flange firmly seats against the carriage
assembly. Secure the slip-ring using the two screws.
6. Attach cable connectors.
On the yoke bracket, connect the cable exiting the
end of the receptacle to the clock-spring cable
connector and tie wrap it to the chassis. Slip the 18-
pin, ribbon cable into its retaining notch and connect
it to Unicard connector P8.
