Flex Power Cable Retrofit Kit
The Flex Power Cable Retrofit Kit (Part Number GK-130618-001), significantly
reduces the chance of plugging the power cable connectors in wrong.
The kit includes the following:
• Two 9-pin connectors (Part Number 101929-609)
• Two keying caps (Part Number 101929-901)
• Drawing Number DI-130618-000
One kit is enough to do one scanner (top and bottom) or two reflection scanners.
The second flex cable (used for ash only) does not use two connectors so it does
not need any rework.
Note: Changing the connectors will not prevent damage if the connectors
are not installed on the cable correctly. The verification procedures
on the instruction drawing are still required when replacing cables.
However, once the cable is correctly made, use of this kit should
prevent the connectors from being plugged in wrong.
Flex Cable Replacements
The correct procedure requires you to verify that the cables are correctly installed
before repowering any sensors. There are two relatively simple ways to do this:
• After plugging the system back together, before repowering the frame, use two
diagnostic cards and do continuity checks between the end column diagnostic
plug and the carriage diagnostic plug.
• Unplug all of the sensor cables, electrometer, chamber supply, and IR
transformer so you can power up the frame without danger of destroying your
sensors. Check the supply voltages on the diagnostic plug (s) at the carriage
before plugging anything back together. Again, refer to your test card inserts.
Doing both checks is recommended to make sure all of the wires are in the right
place and there are not any catastrophic failures.
Figure 10-13 shows the proper cable dress in a SP1200. Note that the longer side
of the power cable plugs into the back connector (towards the drive end of the
carriage board). The short side of the power cable plugs into the front connector
(closer to the idler end). That is done to help from the cable loop so you can slide
the carriage board assembly out.
