Wiring Installation
The Tracer UC400 Controller can be installed on a BACnet MS/TP link, or with the Trane
®
Wireless Communication Interface (WCI), which enables wireless communication. All wiring
must comply with the National Electrical Code (NEC™) and local electrical codes.
Connecting Wires to Terminals
1. Strip the wires to expose approximately a 0.28 inch of bare wire.
2. Insert the stripped wire end into the terminal connector.
3. Tighten the terminal screw 0.5 to 0.6 N-m (71 to 85 ozf-in or 4.4 to 5.3 lbf-in.).
4. Tug on the connected wires after tightening down the terminal screws to ensure all wires are
secure.
BACnet MS/TP Link
The UC400 Controller rotary address dials serve one or two purposes (depending upon the
network) in that they are always used for the MAC Address, which is sometimes all or part of the
BACnet Device ID.
MAC Address
The MAC Address is required by the RS-485 communication protocol on which BACnet operates.
A UC400 Controller can use a MAC Address from 001 to 120. Each device on the link must have a
unique MAC Address/Device ID. The controller rotary addresses should be sequentially set, with
no gaps in the numbering, starting with 001 on each link (for example 001, 002, 003, 004 and so
on). A duplicate address or a 000 address setting interrupts communications and cause the
Tracer SC device installation process to fail.
BACnet Device ID
The BACnet Device ID is required by the BACnet network. Each device must have a unique
number from 001 to 4094302.
BACnet Networks, With or Without Tracer SC Controller
Without a Tracer SC Controller
On BACnet networks without a Tracer SC system controller, the Device ID can be assigned by
two methods:
• It can be the same number as the MAC Address, determined by the rotary address dials on
the UC400 Controller. For example, if the rotary address dials are set to 042, both the MAC
Address and the BACnet Device ID are 042.
• It can be soft set by using the Tracer TU service tool. If the BACnet Device ID is set using the
Tracer TU service tool, the rotary address dials will only affect the MAC Address and will not
affect the BACnet Device ID.
With a Tracer SC Controller
On BACnet networks with a Tracer SC system controller, the Device ID for the UC400 Controller is
always soft set by the system controller (refer to the following table).
NNoottee:: The BACnet Device ID is displayed as the Software Device ID on the Tracer TU Controller
Settings page in the Protocol group.
