10. Extending your Hand-Held Controller
The hand-held controller for your MPC can be placed as far as 1000 feet from the pump. 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.
To replace the cable for the hand-held unit:
POWER TO THE UNIT MUST BE OFF! A GROUNDING WRIST STRAP
SHOULD BE WORN WHEN MAKING CONNECTIONS TO ANY
PCB
10.1 Obtain New Cable:
The following standard length cables are available from Pulsafeeder for use with the MPC:
Cable Length Part Number Notes
6 feet NP530130-000 Standard, supplied with all MPC controllers
Others per foot NP530147-000 (1 ft) NOTE: do not exceed 1,000 feet total length
10.2 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. Disconnect the keypad from the Remote PCB by gently removing the connector at the end of the
keypad’s tail from the header on the PCB.
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. Lift each of the levers 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. 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.
