Pulsafeeder MPC - Manual (Page 43)

12. Extending your Hand-Held Controller
The hand-held controller for your MPC can be placed as far as 1000 feet from
the pump with optional cable. 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
12.1 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
12.2 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. Loosen each of the 6
positions 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.
