Appendix 1, Handheld Wiring; Removal And Connection Of The Cable From The Handheld; Removal And Connection Of The Cable From The Base Unit - Idex Pulsafeeder MPC Vector Installation, Operation & Maintenance Manual

21. Appendix 1, Handheld Wiring

The hand-held controller for your MPC can be placed as far as 1000 feet from the main control unit. It is
recommended that all calibrations be completed before the cable is lengthened, as these tasks are easier when the
pump and hand-held controller are close to each other.
POWER TO THE UNIT MUST BE OFF!
SHOULD BE WORN WHEN MAKING CONNECTIONS TO ANY
The following standard length cables are available from Pulsafeeder for use with the MPC:
Cable Length Part Number
6 feet NP530130-000
Others per foot NP530147-000 (1 ft)

21.1 Removal and Connection of the Cable from the Handheld:

1. Open the handheld unit by removing the 4 screws on the face of the unit.
2. Open the unit by separating the cover from the base.
3. Use care with the keypad tail that is connected to the board, it can be left in place during this process.
4. Make a note of what color lead is in each position of the terminal block "J5". Cut the tie-wrap that secures the
cable. Unscrew each screw on the terminal block "J5" and remove each lead.
5. Loosen the outer domed nut on the liquid tight, releasing the tension on the cable. Pull the cable through the
liquid tight. Thread the new cable through the liquid tight with enough length to reconnect to the terminal
block.
6. Cut the shield wire as close as possible to the outer insulation at the remote end only.
7. Wrap the end of the cable with electrical tape to insulate any remaining shield so that it will not contact the
circuit board, equipment case, or any other parts.
8. Referring to the notes taken earlier, connect each lead of the new cable to the proper position of the terminal
block, lock the lever back in place to hold lead. NOTE: It is recommended that you insert and secure one lead
at a time.
9. Tighten the dome nut of the liquid tight to secure/seal cable.
10. Check that the keypad tail is still firmly connected, re-insert if necessary.
11. Replace cover and tighten screws. Be sure the o-ring is in its groove, paying special attention to the corners.
NOTE: Do not over tighten.
