6.3.7 Replacing the Collimator ID Cable
Procedure Details
The collimator ID cable connects the detector
contact board that engages the collimator to
the EDC module. To change this cable the
detector must be disassembled to the same
level as for changing PMT’s.
1. Follow the procedure to this stage as
described in section 0 on page 6-7.
2. Remove the collimator support cover by
unscrewing the 4 cover screws in the plate
next to the collimator.
3. Disconnect the cable from the detector
contact board and from the EDC module.
4. The cable’s exit hole in the detector
casting is sealed with black RTV. Use a
knife to remove the old seal and replace
the cable.
5. Connect the cable to the detector contact
board and seal the exit hole once again
with black RTV.
6. Route the cable to the EDC module and
re-assemble the detector.

counterclockwise to loosen them. Remove
the sensors.

screw is in place.
