Chapter 1  
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  
of a Tracker controller (Figure 1) and an optional PC workstation.  
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  
(Figure 2 on page 2 and Figure 3 on page 3) that includes HVAC and  
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.

Termination module  
The termination module (Figure 5) is a housing that provides a  
termination board and cable access for power, communications, and  
system input connections. Mounting holes enable it to be mounted on a  
wall or a recessed conduit box. The termination board accepts connections  
for power, communications, and system inputs.

Chapter 1 Overview  
Main module  
The main module (Figure 6) is a housing that contains the main logic  
board and the Ethernet board. The main module can be “hot swapped”: it  
can be removed and installed without removing power from the  
termination module. When the main module is installed onto a powered  
termination module, it receives power and begins to operate  
automatically.  
The main logic board provides an Ethernet LAN port, a PC interface port,  
and a modem port. It provides an internal interface to termination  
module I/O. It also provides Comm5 communication, 24 VAC power,  
alarm, and communication indicators. It communicates and exchanges  
data with the devices wired to the termination module. It also  
communicates with the display module.  
The Ethernet board provides two LED indicators. One shows that an  
Ethernet link is detected; the other shows that there is serial traffic  
between the Ethernet board and the main logic board.

Display module  
The display module (Figure 7) is a housing that contains a printed circuit  
board, liquid crystal display (LCD) touch screen, and an alarm LED. The  
printed circuit board supports the LCD touch screen and the alarm LED.  
The touch screen provides the operator access to the user interface  
program.  
The display module can be “hot swapped:” it can be removed and installed  
without removing power from the main module. When the display module  
is installed onto a powered main module, it receives power and begins to  
operate automatically.

Termination module  
mounting  
After unpacking and inspecting the shipment, mount the termination  
module. The mounting process for the termination module consists of  
selecting a location and mounting the module. This chapter provides  
information and procedures that enable you to mount the termination  
module.  
Select a location for the controller  
When selecting a location for the Tracker controller:  
Select a location that is in a clean, non-corrosive, indoor environment.  
The controller is only intended for indoor installation.  
Consider both security and control wire lengths when making the  
selection.  
Select a location that limits controller access to operating and service  
personnel.  
Select a location that conforms to the operating environment  
described in Table 1 on page 9. The recommended operating environ-  
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  
electrical noise. The electrical interference may lead to control malfunc-  
tions.

Chapter 2 Termination module mounting  
Securing the termination module to a wall  
1. Mark the location of the two mounting holes on the wall.  
2. Set the termination module aside and drill mounting holes.  
3. Secure the termination module to the wall with the supplied hard-  
ware (#10 × 1 in. screw with plastic anchor).  
Securing the termination module to a conduit box  
1. Remove the screws from the conduit box.  
2. Line up the conduit box screw holes on the termination module  
(Figure 12 on page 19) with the screw holes on the conduit box.  
3. Install the screws.  
Note:  
When mounting the termination module to a 4 in. × 4 in.  
conduit box, removing the plastic cover over the box will  
provide easier access. Do not attempt to break away excess  
plastic. Instead, use a hack saw blade and carefully cut away  
the plastic.

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-

Termination board wiring  
After mounting the termination module, wire the termination board. The  
wiring process consists of wiring the termination board to 24 Vac power,  
inputs, outputs, and UCMs. This chapter provides information and  
procedures that enable you to wire the termination board. Figure 14 on  
page 24 shows all field wiring connections.  
Refer to the required and optional supply checklists in Appendix A  
(Table 15 and Table 16 on page 65) to verify that you have the materials  
required to wire the Tracker controller. When termination board wiring is  
complete, use the termination module post-installation checklist in  
Appendix A (Table 18 on page 70) to verify the wiring.

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  
suppliers. Table 7 on page 30 shows the Trane approved suppliers;  
Table 8 on page 31 provides the specifications for Level 4 compliant  
cables.

Termination resistor placement for Comm5 links  
Install one 105 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 resistor across the communication  
terminals at the last UCM on each link. See Figure 17 on page 35 for an  
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 resistors  
that are included with the Tracker controller. If they are not available, as  
a second choice, use a 100 , ¼ W, 5% tolerance resistor, or as a third  
choice, a 110 , 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.

Brown, black, green, brown  
Brown, black, brown, gold  
Brown, brown, brown, gold  
105 1% tolerance  
100 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-  
cation wiring (Figure 12 on page 19).  
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).  
BMTK-SVN01D-EN  
37  
 
 
 
 
 
 
 
href="
®
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.  
Recommended shield connections are shown in Figure 19. Figure 20 on  
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.

Main module mounting  
After mounting and wiring the termination module, attach the main  
module to the termination module. This chapter provides information and  
procedures that enable you to mount the main module.  
Note:  
The Tracker controller ships with the display module  
assembled to the main module. If those two modules are  
assembled, performing this procedure also mounts the display  
module.  
Note:  
It is not necessary to turn off 24 Vac power to the Tracker  
controller prior to mounting or removing the main module.  
1. Verify that all wires on the termination module are securely fastened  
in place.  
2. Carefully line up the alignment pins on the termination module with  
the back side of the main module (Figure 21 on page 42).  
CAUTION  
Avoid Equipment Damage!  
Do not use excessive force when mounting the module. If the module  
does not snap easily into place, slightly reposition it on the alignment  
pins. Failure to comply may cause damage to the module.  
3. Firmly push the main module onto the termination module until it  
snaps into place. If 24 Vac power is applied, the main module will  
start. If the display module is not assembled to the main module, you  
will see the LEDs on the main module flash on and off after a few sec-  
onds. If the display module is assembled to the main module, it will  
turn on and display information.

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.  
Verify that the telephone cable is connected to the PC modem port (Figure 24 on  
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.  
Verify that the cable is connected to the PC direct connect port (Figure 24 on  
page 48).  
Verify that the proper cable is used. (Refer to Table 10 on page 47.)  
Verify that the PC workstation is using the Tracker controller software; other com-  
munications software will not work.  
Look for activity on the PC RX LED (Figure 30 on page 56).  
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.  
Verify electrical connection using the post-installation checklist (Table 18 on  
page 70).  
Verify I/O status as indicated on home display on the display module.  
Display Tracker I/O status self test from display module.

Symptom  
Action  
Tracker alarm output is not  
working as expected.  
Confirm proper wiring of the alarm relay output. Consult the post-installation  
checklist (Table 18 on page 70) for details.  
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-  
ton (S1) on the main module (see Figure 30 on page 56).  
Note: Heartbeat LED (HRT LED5) will be solid green.  
Alarm LED on the display is  
flashing red.  
At the Tracker controller user interface home screen, push the alarm button on  
the display module to acknowledge the alarm, then take the proper corrective  
action.  
Note: The alarm LED flashes when the controller receives an alarm of the appropriate severity.  
Pressing the Alarm button acknowledges the alarm and turns off the flashing LED (until the control-  
ler receives another alarm of the appropriate severity).  
Tracker controller is annun-  
ciating an alarm.  
At the Tracker controller user interface home screen, push the alarm button on  
the display module to acknowledge the alarm, then take the proper corrective  
action.  
Note: The alarm relay energizes when the controller receives an alarm of the appropriate severity.  
Pressing the alarm button acknowledges the alarm and turns off the alarm relay output (until the  
controller receives another alarm of the appropriate severity).  
Display module is not illu-  
minated.  
Press anywhere on the touch screen surface to turn the back light on. The control-  
ler automatically turns off the back light during extended periods of inactivity to  
conserve energy and bulb life.  
Confirm that the controller has 24 Vac power. When the display module has  
power, the alarm LED will be either solid green or flashing red.  
Display module does not  
respond to the touch.  
Confirm that the controller has 24 Vac power. When the display module has

the wrong date.  
Verify if the electrical power has been off for more than 1 week (the actual time  
varies depending on storage temperature).  
Verify that jumper pin J1 on the main module is in place.  
Note: The controller default date (displayed when the controller is initially powered up or whenever  
the super capacitor is unable to back up the controller time) is January 1, 2000.  
Outdoor air temperature is  
not reading correctly.  
Measure the resistance of the outdoor air temperature thermistor (preferably at  
the termination module). Check the measurement using Table 19 on page 71.  
Inspect the location of the outdoor air temperature sensor. It must not be  
mounted in the sunlight or near another source of radiant heat.  
Note: The outdoor air temperature sensor can be used for this purpose only.  
Ethernet link is not detected  
(on the Ethernet board, the  
left LED is off)  
Verify that the correct type of cable is used. When communicating over a network,

There must be no voltage applied to these terminals. The cable  
shield must be connected to terminal TB1-12. Measure the resis-  
tance between TB1-10 and TB1-11.  
TB1-10,  
TB1-11,  
TB1-12  
Note the approximate temperature at the location of the outdoor  
air temperature sensor.  
Compare the resistance and temperature values to the listed val-  
Comm  
There must be no voltage applied to these terminals. Measure the  
resistance between TB1-13 and TB1-14. The resistance must be  
approximately 50 with daisy-chained wiring. This test confirms  
the correct usage of the termination resistors as well as the conti-  
nuity of the wire.
