Trane BCXC-SVX01B-EN, BCVC, BCHC manual Installation Controls, Service Communication Wiring

Installation Controls

b.Pull the control wires through the cutout. Attach the module to the wall using the screws provided.

5.Strip the insulation on the interconnection wires back 0.25 inch and connect to TB1. Screw down the terminal blocks.

6.Replace the zone sensor cover and adjustment knob.

If installing a Tracer™ ZN510 or ZN520 zone sensor, see “Tracer Summit Communication Wiring,” p. 27 for more information.

Communication Wiring

Units with Tracer ZN510 or ZN520 only

Note: Communication link wiring is a shielded, twisted pair of wire and must comply with applicable electrical codes.

Follow these general guidelines when installing communication wiring on units with either a Tracer™ ZN510 or ZN520 controller:

•Maintain a maximum 5000 ft. aggregate run

•Install all communication wiring in accordance with the NEC and all local codes.

•Solder the conductors and insulate (tape) the joint sufficiently when splicing communication wire. Do not use wire nuts to make the splice.

•Do not pass communication wiring between buildings because the unit will assume different ground potentials.

•Do not run power in the same conduit or wire bundle with communication link wiring.

Service Communication Wiring

Establish service communication using Rover™ service software connected to the Tracer™ ZN controller using a twisted wire pair to one of the following connection points:

•Remote zone sensor module

•Connections on the board

This allows the technician to view and edit the Tracer™ controller configuration and troubleshoot the unit.

Note: Unit control options and field wiring practices may limit the controller’s communication ability.

Route interconnecting wiring from the Tracer™ controller to provide service communication at the wall-mounted zone sensor module. Install wiring by referencing the unit wiring diagram and Table 12, p. 29 for appropriate wire sizes. After wiring is complete, connect the communication cable (provided with the Rover™ service tool) to the telephone style RJ11 connection on the zone sensor module. Attach the other end of the cable to a computer running Trane Rover software to communicate.

Zone Sensors Without Interconnecting Wiring

Establish service communication to the Tracer™ ZN controller by wiring directly to the board inside the control box. Refer to the unit-wiring diagram for appropriate communication terminals on the board.

Once wiring is complete, Use Trane Rover™ software to communicate to the Tracer™ ZN controller.

Tracer Communications

Tracer™ ZN controllers have Comm5 communication ports. Typically, a communication link is applied between unit controllers and a building automation system. Communication also is possible via Rover™, Trane’s service tool.
