1. Unplug main power and air value AMP connectors (See Appendix C).
2. Remove all AMP connectors from the top of the machine. (Please note
positioning.) Unscrew the plastic ring at the base and the connector will pull
out.
3. Remove amplifier cables. (It’s very important to note positioning here) Do not
unscrew each lead. Each cable is screwed in to a connector. The connector
itself will pull out of the slot in which it is housed on the PCB board.
4. Remove motor control signal cable (See Appendix C). It is very important to
note the orientation. The connector will have a white mark on one side. That
mark locates pin one. You must be sure to plug it back in with the white mark
on the same side as the “1”, as indicated on the junction board.
5. Remove both the motion control main connector and the motion control
auxiliary connector. (See Appendix C for position.)

8. Screw each of the six screws back into place.
9. Replace all AMP connectors on the top side of the deck. (Please note
positioning.)
10. Replace all amplifier connectors on the bottom side of the deck. (Again,
please note positioning.)
11. Replace motor control signal cable. It is very important to note the orientation.
The connector will have a white mark on one side. That mark locates pin one.
You must be sure to plug it back in with the white mark on the same side as the
“1”, as indicated on the junction board.
12. Inspect motion control main and auxiliary cables for bent pins or overall
damage.
13. If cables are fine, place them back in to position.
14. Replace all other AMP connectors on the bottom side of the deck.
15. Double check to see if all cables is properly seated.

This completes the replacement procedure.
