Notes:
1. Seal all conduit fittings against water entry. Install drain holes at conduit’s lowest elevation(s) to allow
condensation to drain.
2. Wiring for transducer, from junction box to controller: Use Belden 8760 two-conductor twisted shielded
pair cable. Maximum lengths are:
• 56T-25 — 750’ (228 m)
• 56T-50 — 1000’ (304 m)
3. For runs up to 1200 ft (365 m) for all transducers, RG62U coaxial cable can be substituted.
4. Wiring for temperature probe (optional) from junction box to controller: Use Belden 8790 two conductor
twisted shielded pair cable.
5. All wiring routed between junction boxes and controller must be continuous (no splices).
WIRING JUNCTION BOX TO CONTROLLER
1. The Scanner PCB can be temporarily removed from the controller to make wiring easier.
See Figure 4: Wiring Transducers to Controller for wiring at the junction box.
• Transducer Interconnect — cut the shield wire at the J-Box end of the cable only. Connect this end
of the cable to the junction box terminals.
• Temperature probe Interconnect — connect one end of the cable to the junction box terminals.
2. If wiring a single transducer to the controller (see Appendix E)
• Connect the transducer wiring to TB7 on the motherboard (on right side).
• Connect the temperature probe wiring (optional) to TB6 on the motherboard (to left of TB7).
3. If wiring multiple transducers to the controller (see Appendix E)
• Connect the transducer wiring to the designated terminals on the Scanner PCB.
• Connect the temperature probe wiring (optional) to the designated terminals on the Scanner PCB.
