Overview
The Tracker building automation system (BAS) is an energy management
system for small- to medium-size buildings. The Tracker BAS controls
heating, ventilating, and air conditioning (HVAC) equipment. It consists
The Tracker BAS can be operated by using either a Tracker controller or a
PC workstation that is running Tracker PC Workstation software. A
visual interface enables an operator to set up and change HVAC
operating parameters and to collect and display building information.
The Tracker PC Workstation software allows a PC to be connected to the
Tracker controller directly with a prescribed adapter and cable, locally
over a standard Ethernet local area network (LAN) connection, or
remotely with a modem and standard phone line.
The Tracker BAS supports Comm5 communications architecture, which
is the Trane implementation of LonTalk® protocol. It resides on a network
other comfort-related equipment, such as Trane VariTrac zoning systems;
zoning controls; unit control modules (UCMs), which control and monitor
other HVAC equipment; Tracer LCI-V (LonTalk® communication
interfaces for Voyager rooftop controls); Tracer LCI-R (LonTalk®
communication interfaces for ReliaTel rooftop controls); external input/
output (I/O) devices, which help to monitor and control specific areas or
devices; and miscellaneous equipment such as sensors, lights, and fans.

ment will extend the life of the electronic components. Verify that the
location does not subject the controller to extreme operating condi-
tions (including excessive vibration).
CAUTION
Avoid Equipment Damage!
Install the Tracker controller out of direct sunlight. Failure to do so may
cause overheating, which could result in equipment damage.
IMPORTANT
Do not install the Tracker controller near high-power radio signals, elec-
trical switching gear, power buses, large motors, or other sources of

Mount the termination module
Installing electrical conduit
Use the conduit openings on the top of the Tracker termination module to
supply power or communication wires to the controller.
If the controller is mounted on a wall, you must use electrical conduit. If
the controller is mounted to a conduit box through which power, input/
output, and communications are supplied, you do not need to use
electrical conduit.
IMPORTANT
The 24 Vac wire conduit may not contain input/output or communica-
tion wires. Failure to comply will cause the Tracker controller to mal-
function due to electrical noise.
1. Remove one of the 7/8 in. (22 mm) diameter plugs at the top of the ter-
opening.
3. Install the conduit jamb nut on the conduit connector threads and
tighten it to secure the connector to the Tracker panel.

Wire the UCMs
Wire the UCMs
The Comm5 communication link connects unit control modules (UCMs)
to the Tracker termination module. Each controller has one Comm5
communication link. This topic includes information and procedures for
wiring a UCM to a termination module:
Note:
Do not exceed the maximum number of UCMs that can
communicate on a Tracker controller (see “UCM maximum
Wire specifications
Tracker Comm5 communication-link and sensor wiring is low-voltage
Class 2 wire and must be field-supplied and installed in compliance with
NEC and local codes. To prevent electrical noise interference, all wiring
must comply with requirements outlined in this topic for wire selection
and link-wiring topology.
Trane recommends that you use Level 4 (Echelon) shielded cable for the
Tracker communication link wiring between the Tracker and the Comm5
UCMs to which it communicates. Trane also recommends that you use it
for communication wiring between the VariTrac CCP and its associated
VariTrac or VariTrane UCMs, and for sensor wiring to these devices.
Level 4 cable is available in shielded, plenum and non-plenum versions.
Level 4 cable is available from Trane-approved suppliers as well as other

Termination resistor placement for Comm5 links
Install one 105 Ω resistor across the communication link terminals of the
device at the beginning of the daisy chain, which is typically a Tracker
controller. Then install a second 105 Ω resistor across the communication
example of a link that begins with a Tracker controller. See Figure 18 on
page 36 for an example of a link that does not begin with a Tracker
controller.
Note:
If, after installation, the link is extended to add more UCMs,
the resistor must be relocated to the new last UCM on the link.
IMPORTANT
For maximum performance of the Comm5 link, use the 105 Ω resistors
that are included with the Tracker controller. If they are not available, as
a second choice, use a 100 Ω, ¼ W, 5% tolerance resistor, or as a third
choice, a 110 Ω, ¼ W, 5% tolerance resistor. Failure to comply may cause
the controller to malfunction.
The resistor value can be determined by reading its color bands. Table 9
provide the resistor color coding.

Tolerance
Color sequence
Brown, black, green, brown
Brown, black, brown, gold
Brown, brown, brown, gold
105 Ω 1% tolerance
100 Ω 5% tolerance
110 Ω 5% tolerance
If a repeater is used, each link of the configuration that is created by the
repeater requires termination resistors (see “Requirements for repeaters
Create a set of as-built drawings or a map of the communication wire
layout during installation. Ensure that sketches of the communication
layout show the placement of the termination resistors.

Wire the UCMs
Wire supported UCMs
Wire the supported UCMs to the Tracker termination board. When
installing communication wire:
•
Keep the polarity consistent throughout the site. Although Comm5 is
not polarity sensitive, consistency will improve serviceability.
•
Strip away a maximum of 2 inches (50 mm) of the outer conductor
and foil shield when splicing or terminating shielded wire.
IMPORTANT
Use extreme care when stripping away the outer conductor and foil
shield. Be careful not to nick the insulating jacket of the two conduc-
tors. A nick in the insulating jacket will cause communication problems.
Wire the UCMs as follows:
1. Install termination resistors in the correct locations.
2. Route input wires into the termination module through the conduit
box or any of the conduit openings designated for input and communi-
3. Connect the wires to the COMM terminals on the termination board
4. Connect the shield to the ground terminal.
5. Connect the other end of the wires to the UCMs, as necessary.
Requirements for repeaters on Comm5 communication
links
The Comm5 communication link repeater is a device that repeats and
regenerates the signal on a Comm5 link in order to enhance signal
quality or extend the length of the run. The Comm5 link goes from the
Tracker controller to the UCMs to the repeater. A second link segment
extends from the other side of the repeater to the rest of the devices. The
configuration on either side of the repeater must be a daisy-chain
configuration. Both link segments require termination.
A link repeater is required when:
•
The total wire length is greater than the maximum wire run length of
4593 ft (1400 m) for a daisy-chain configuration.
•
More than 60 devices are connected to a link. This total does not
include the Tracker controller, the link repeater, and the possible use
of the Rover service tool on the same link.
The link repeater has several limitations:
•
•
Only one link repeater can be used on a link.
The use of a repeater doubles the maximum allowable wire length.
For example, when a repeater is used with a daisy-chain configura-
tion, the total wire length can be 9186 ft (2800 m) (with half the wire
length on either side of the repeater).

Chapter 3 Termination board wiring
•
•
The link repeater is limited to 60 devices on either side of the link
(120 devices total).
The link repeater requires an earth ground. The installer should be
aware of this before making power connections.
page 39 shows a daisy-chain repeater connection. Follow these guidelines
when using a repeater:
•
Reference the installation information that comes with the link
repeater (Comm5 repeater installation, 3270 3285).
•
Connect the shield-drain wires entering the repeater to a terminal
marked with a capacitor symbol. The entering shield-drain wire must
be connected to earth ground at the Tracker controller.
•
Connect the shield-drain wires leaving the repeater to the repeater
terminal marked with an earth ground symbol.

Symptom/action troubleshooting
Symptom/action troubleshooting
Table 14 provides a list of symptoms that indicate a problem in the Tracker system.
For each symptom, the table provides one or more actions that you can perform in an
attempt to resolve the problem.
Table 14. Symptom/action troubleshooting
Symptom
Action
Tracker controller does not
communicate by modem.
page 48).
• Verify that the phone line is an analog line (not digital).
• Perform the modem self-test procedure from the display module.
Note: The modem is an integral component of the main module and is not field replaceable.
Replacement of the modem requires replacement of the main module.
Tracker controller does not
communicate by EIA-232
port.
page 48).
• Verify that the PC workstation is using the Tracker controller software; other com-
munications software will not work.
Tracker controller did not
discover UCMs when ini-
tially started.
When the controller is initially powered up, it automatically discovers all communi-
cating UCMs of the proper type and installs them into its database. The discovery
process takes several minutes, depending on how many UCMs are installed on the
communication link.
After the controller has built its database after the initial power up, the controller no
longer automatically discovers UCMs. If you want to initiate the discovery process,
you must do so manually. Initiate the discovery process when a new UCM is added
to the system or an existing UCM is replaced.
• Verify proper wiring of the Comm5 communication link. (UCMs can be discov-
ered only if Comm5 communication has been established.)
• Wait at least 5 minutes for the controller to discover the UCMs.
Note: You can press the service pin button on a UCM at any time to check if it is communicating
with the controller. Pressing the service pin button causes the UCM status LED to flash on and off
(known as “winking”), if the controller is communicating with that UCM.
Touch screen beeps when
touched but does not
progress to the next screen.
Touch screen is out of calibration.
• Perform the procedures for calibrating the touch screen in Tracker Building Auto-
mation System Controller Operations guide (BMT-SVU01A-EN).
Touch-screen back light and
contrast is out of adjust-
ment.
• Perform the adjust brightness and contrast procedure from the display module.
Tracker I/O status is wrong.

Tracker alarm output is not
working as expected.
• Confirm proper wiring of the alarm relay output. Consult the post-installation
• Initiate the BOP self test from the display module.
Note: The binary output is for alarm notification only. There must be an unacknowledged alarm
present of the proper severity to actuate the alarm output.
Tracker controller will not
communicate with its
UCMs.
• Look for wiring problems (shorts or opens, for example) that develop when wire
is damaged during installation.
• Look for shorts between the two conductors resulting from nicks in the insulating
jacket. (This can be caused by improper technique when stripping away the outer
jacket and shield.)
• Look for a strong source of EMI/RFI interference nearby.
• Look for ac power disturbances from nearby transformers and electrical equip-
ment. This is especially true when running communication links in close proxim-
ity to florescent lighting ballasts.
• Verify the UCM has not failed.
• Verify proper termination resistance.
Tracker processor is locked
up.
• Cycle power to the Tracker main module by removing it from the termination
module.
• If the processor is still locked up after cycling power to the controller, perform a
reboot from the display module or the PC software (if the controller is able to
communicate).
• If the controller will not respond to the above listed methods, push the reset but-
