Before Installation

Before installation:

• Be sure all items on the packing list are included and are

not damaged.

• Familiarize yourself with this guide and any support literature.

• Formulate a comprehensive installation plan for the entire Tracer

Summit system.

Tracer Summit System Overview

The Tracer Summit system provides building automation and energy management functions. The system is capable of monitoring and controlling heating, ventilating, and air conditioning (HVAC) equipment and providing management information and operator override capabilities. Figure 1 on page 2 shows the options for a Tracer Summit system configuration. For a complete list of Trane Comm5 unit controllers, see Table 7 on page 46.

The interface for Tracer Summit uses a graphical format that is accessible through a PC Workstation. You can connect the PC Workstation and building control unit (BCU) over an Ethernet LAN or an ARCNET LAN, or remotely using modems specified by Trane.

The Modular BCU (BMTW) and the BCU (BMTS)

The main purpose of this installation guide is to provide hardware and software installation guidance for the modular BCU (BMTW). In the body of this guide, the term BCU refers to the modular BCU (BMTW). In Chapter 6, “Network Wiring,” where both BCU models are discussed, the terms modular BCU (BMTW) and BCU (BMTS) are used.

Appendix B provides hardware installation guidance and troubleshooting for owners of the BCU (BMTS). In Appendix B, the term BCU refers to the BCU (BMTS).

BCU Components

The BCU (see Figure 2 on page 4) is a NEMA-1 rated enclosure that houses the following:

• A standard capacity card (required)

• An optional high capacity card

• A terminator block (TB2)

• An optional I/O module with five universal inputs (UIPs), which can

be either analog or binary, and one binary output (BOP)

• Four unit control module (UCM) communication card slots for com-

munication links 1, 2, 3, and 4

• Three card slots for option cards supplied by Trane, such as Ethernet

cards, ARCNET cards, modem cards, or EIA-232 communication cards for BACnet interface

• A seven-segment LED display for displaying BCU operation status;

the LED operation and codes are described in Chapter 10, “BCU Operation and Communication Status”

• An operator display socket for attaching the optional BCU operator

display

• A mini-monitor port for attaching a PC with a straight-through

EIA-232 cable to access built-in diagnostic software; this port is intended to be used by trained service technicians

Note:

If a BCU has an optional operator display, you need to unplug the operator display ribbon cable from the operator display socket and wait 10 seconds before the mini-monitor port becomes active.

The main function of the BCU is to communicate with UCMs, PC Workstations, and other BCUs, and to execute all application programs.

UCM Communication Links—Wiring Requirements

UCM Communication Links— Wiring Requirements

Twisted-Pair Wire—Comm2, Comm3, and Comm4

All unit control modules (UCM) communication-link wiring must be 18gauge, shielded, twisted-pair wire with stranded, tinned-copper conductors.

The maximum length of link wiring (5,000 ft [1,524 m]) is a function of the total resistance (which is determined by wire length) plus the capacitance between conductors. Wire capacitance between conductors is an important aspect of the UCM communication link. The wire should have a maximum capacitance between conductors of 25 pF/ft (78 pF/m) for connections up to 5,000 ft (1,524 m) maximum. Trane recommends that only low-capacitance wire supplied by Trane be used for UCM communication links. For UCM communication-link wiring, see Chapter 4, “UCM Communication-Link Wiring.” UCM communication and sensor wire is available through your local Trane commercial sales office.

Twisted-Pair Wire—Comm5

The recommended Comm5 communication-link wiring is 22-gauge, Level 4, twisted-pair wire. The wire can be either shielded or unshielded. You can also use 18-gauge, shielded, twisted-pair with stranded, tinnedcopper conductors (Trane “purple” wire).

Note:

Do not mix wire types on a Comm5 link.

The maximum wire length for Comm5 communications is 4,500 ft (1,400 m).

Fiber-Optic Cable

Fiber-optic cable is used for applications involving long distances because there is little degradation of optic signals. Fiber-optic cable maintains the integrity of the signal in the presence of various sources of electrical noise, including lightning, electromagnetic interference/radio-frequency interference (EMI/RFI), voltage conductors, and ground loops.

Note:

Use fiber-optic cable for long distances, interbuilding cabling, and/ or other areas of high electrical noise, such as petrochemical installations, electronic rooms, and hospital nuclear magnetic resonance (NMR) or X-ray rooms.

BMTW-SVN01F-EN 5

Page 21

Chapter 1 Before Installation

Trane requires duplex, 62.5 µm core glass fiber-optic cable with ST connectors. The types of cable available for different applications include indoor, outdoor, burial, aerial, and duct. Further descriptions of fiberoptic cable and accessories are provided in Chapter 4, “UCM Communication-Link Wiring.”

You can order fiber-optic cables, fiber-optic modems, ST-type crimp connectors, epoxy connectors, and other accessories from Trane.

LAN Communication Links— Wiring Requirements

Coaxial Cable (10Base2 or “Thinnet”)—Ethernet

Use a 50 Ω coaxial cable (RG-58) for the Tracer Summit Ethernet link. No other coaxial cable is supported.

You can order all Ethernet cables, adapters, crimp tools, stripper tools, and other coaxial accessories from Trane.

For information about maximum cable length and maximum cable distance between two devices on a communication link, refer to Table 30 on page 152.

Note:

Cable installations must comply with both federal and local codes. Plenum-rated cable is available to meet NEC Article 725, which addresses flame resistance and smoke emission for signal cables.

Unshielded, Twisted-Pair Wire (10BaseT)—Ethernet

In twisted-pair wiring, one pair is used to receive data signals and the other pair is used to transmit data signals. The two wires in each pair must be twisted together for the entire length of the segment to maximize the signal-carrying characteristics of a wire pair. Multiple twisted-pair segments communicate via a multiport hub.

You can only use twisted-pair wiring between a device (BCU or PC Workstation) and a hub. If a direct connection between two devices is required, then you must use a hub or crossover cable. For information about maximum wire length and maximum wire distance between two devices on a communication link, refer to Table 30 on page 152.

Use Trane-supplied Category 5 cables, jumpers, connectors, and wire terminating devices. These components work well for twisted-pair wires and provide the best possible signal-carrying system for the Ethernet media systems.

The EIA/TIA cabling standard recommends a segment length of 295 ft (90 m) between the wire termination equipment in the wiring closet and the wall plate in the office. This provides 33 ft (10 m) of cable allowance to

LAN Communication Links—Wiring Requirements

accommodate patch cables at each end of the link and signal losses in intermediate wire terminations on the link.

IMPORTANT

Due to the high precision required when performing twisted-pair wire terminations, Trane recommends that only qualified technicians with the proper equipment handle all terminations and splicing.

Note:

Cable installations must comply with both federal and local codes. Plenum-rated cable is available to meet NEC Article 725, which addresses flame resistance and smoke emission for signal cables.

Coaxial Cable—ARCNET

Use a 93 Ω coaxial cable (RG-62) for the Tracer Summit ARCNET link. No other coaxial cable is supported.

You can order all ARCNET cables, adapters, crimp tools, stripper tools, and other coaxial accessories from Trane.

For information about maximum cable length and maximum cable distance between two devices on a communication link, refer to Table 30 on page 152.

Note:

Cable installations must comply with both federal and local codes. Plenum-rated cable is available to meet NEC Article 725, which addresses flame resistance and smoke emission for signal cables.

Fiber-Optic Cable—Ethernet and ARCNET

Use fiber-optic cable for applications involving long distances. There is little degradation of optic signals when using fiber-optic cable, and the integrity of the signal is maintained in the presence of several sources of electrical noise including lightning, EMI/RFI, voltage conductors, and ground loops.

Use a duplex, 62.5 µm core glass fiber-optic cable with ST connectors for the Tracer Summit Ethernet or ARCNET link. There are a variety of cables available for different applications including indoor, outdoor, burial, aerial, and duct.

You can order fiber-optic cables, fiber-optic modems, ST type crimp connectors, epoxy connectors, and other accessories from Trane.

BMTW-SVN01F-EN 7

Page 23

Chapter 1 Before Installation

IMPORTANT

Due to the high precision required when performing fiber-optic terminations, Trane recommends that only qualified technicians with the proper equipment handle all terminations and splicing.

Note:

Use glass fiber-optic cable for long distances, interbuilding cabling, and/or other areas of high electrical noise, such as petrochemical installations, electronic rooms, and near hospital NMR or X-ray rooms.

Optical-Link Loss Budget

Every fiber-optic link has some signal loss (measured in decibels). Many factors affect decibel loss, including:

• Length of fiber-optic cable

• Transmitter optical output power

• Operating wavelength

• Fiber attenuation

• Fiber bandwidth

• Receiver optical sensitivity

The decibel loss between any two devices is based on how well the terminations or splices are made. The decibel loss can vary from 0.5 to 2 dB. A clean splice results in increased performance. For example, the fiber-optic ARCNET card that Trane supports has a power budget of 10 dB. The decibel loss for fiber-optic cable provided by Trane is 3.75 dB/km (1 km = 3280 ft). Precut fiber-optic cables and professionally spliced and/ or terminated cables should ensure minimal decibel loss.

To calculate the system loss, subtract the cable loss, splice loss, terminator loss, and patch panel loss from the power budget. The example below shows typical values for the ARCNET communication link:

power budget – system safety margin = available budget

10 dB – 3 dB = 7 dB (available budget)

available budget: 7 dB

cable loss: – 3.75 dB (1 km at 3.75 dB/km)

allowance for splice loss: – 1 dB (2 at .5 dB)

allowance for end connectors: – 1 dB (2 at .5 dB)

allowance for patch panel: – 1 dB (2 at .5 dB)

excess margin: = 0.25 dB

Remote Communication Requirements and Specifications

The Tracer Summit BCU supports remote communication with a PC Workstation. Remote communication requirements and specifications are described in the following sections.

Communication Rate

The BCU supports a maximum communication rate of 33,600 bps.

Communication Protocol

Communication between the BCU and a PC Workstation is performed using the BACnet point-to-point (PTP) protocol.

BCU Internal Modem

For remote communication, a single, internal modem card must be installed in one of the BCU’s option card slots (see Figure 2 on page 4). Trane reserves the right to support only specified modems, because modem specifications are subject to change. This ensures proper operation and helps facilitate technical support if communication failures occur.

Note:

You cannot install an EIA-232 communication card for BACnet interface and an internal modem in the same Tracer Summit BCU.

PC Workstation Modem

The Tracer Summit PC Workstation supports up to three internal or external modems. (The resources available on any given PC Workstation will dictate the number of modems able to be connected.)

2. To avoid damage to the BCU logic board and resin front cover, store them at another location during building construction.

3. On the wall, mark the location of the four mounting holes in the BCU back panel.

4. Set the back panel aside and drill the mounting holes.

5. Secure the back panel to the wall with the M6 (

¼ in.) hardware.

Install the Optional Operator Display

If you purchased the optional BCU operator display, refer to “Installing the Optional Operator Display” on page 33, then proceed to “BCU Power Wiring for International Installations” below.

BCU Power Wiring for International Installations

The BCU power wiring procedure consists of verifying compliance with the BCU circuit requirements and then connecting the ac-power wires. (See also “Preliminary AC-Power Checkout” on page 30.)

Verify Compliance with Circuit Requirements

To make sure that the BCU will operate properly, verify that the power supply circuit is in compliance with these circuit requirements:

• The BCU must receive power from a dedicated power circuit. Failure

to comply may cause control malfunctions.

• The ac-power wire conduits or wire bundles must not contain

input/output wires. Failure to comply may cause the BCU to malfunction due to electrical noise.

28 BMTW-SVN01F-EN

Page 44

BCU Mounting and Power Wiring for International Installations

• The ac-power wiring must comply with the National Electrical Code

(NEC) and applicable local electrical codes.

• The ac-power wiring requires three-wire 120/240 Vac service. Use

copper conductors only.

CAUTION Use Copper Conductors Only!

Unit terminals are not designed to accept other types of conductors. Failure to use copper conductors may result in equipment damage.

Note:

The BCU transformer voltage utilization range is 98–132 Vac (120 Vac, nominal) or 196–264 Vac (240 Vac, nominal). The panel determines whether the current is 50 or 60 cycle.

Connect the AC-Power Wires

To connect the ac-power wires to the BCU:

nWARNING Hazardous Voltage!

1. Lock open the supply-power disconnect switch.

CAUTION Avoid Equipment Damage!

Be careful when punching out the conduit knockout. Failure to do so may cause damage to internal components.

2. At the upper left corner of the BCU, punch out either of the 22 mm

(

/8 in.) 120/240 Vac knockouts (see Figure 8 on page 30).

3. Access the power supply wiring by removing the BCU cover and the block-off that covers the power supply area at the top of the BCU.

4. Set the line voltage switch to match the supply voltage (120–240 Vac).

5. For 120 Vac, connect the black wire (or other color wire that is not white or green) to the top terminal block position (see Figure 8 on page 30). Then connect the white wire to the middle terminal block position.

6. For 240 Vac, connect the black wire (or other color wire that is not white or green) to the top and middle terminal block positions.

BMTW-SVN01F-EN 29

Page 45

Chapter 2 BCU Mounting and Power Wiring

7. Connect the green ground wire to the bottom terminal block position. The ground wire should be continuous back to the circuit breaker panel.

8. On a label, record the location of the circuit breaker panel and the electrical circuit. Attach the label to the ac-power cover inside the BCU.

CAUTION 4-Amp maximum set up tool receptacle

The SET UP TOOL ONLY receptacle must only be used to power a laptop PC service tool. The PC must not exceed a 4 A draw with a maximum acceptable leakage current of 3.4 mA.

Installing and Wiring the BCU Logic Board

2. Make sure that all internal connections are secure, then check for ac or dc voltages for safety purposes. For BCU input power wiring and internal cable connections, see Figure 2 on page 4.

3. Check for ac and dc shorts to ground by disconnecting all power to the BCU and measuring the resistance between the hot and neutral leads on the 120/240 Vac power supply. The proper resistance reading should be 33 Ω (5 Ω with an optional 24 Vac transformer).

4. Energize the BCU power supply circuit, and then check the voltage between each pair of wires on the ac-power termination block. The voltages measured should match the values in Table 4.

Table 4. BCU Power Supply Voltages

Power Voltages

120 Vac

• 98–132 Vac between black wire and white wire

• Less than 5 Vac between white wire and ground

• 98–132 Vac between black wire and ground

240 Vac

• 196–264 Vac between black wire and orange wire

• 98–132 Vac between orange wire and ground

• 98–132 Vac between black wire and ground

5. De-energize the BCU power supply circuit by opening the circuit breaker at the power distribution circuit breaker panel.

6. Reinstall the block-off cover over the power supply area in the BCU enclosure.

Installing and Wiring the BCU Logic Board

The BCU logic board assembly is shipped in its own packaging so that it can be stored in a safe location while construction or electrical wiring is in progress. After all ac-power wiring is complete, mount and wire the BCU logic board assembly.

CAUTION Possible Equipment Damage!

The BCU logic board should be installed only after building construction or electrical wiring is at a point when there is no risk of damaging the electronics of the logic board.

To install and wire the logic board:

1. Remove the BCU logic board assembly from the packaging material.

2. Inspect the applicable unit control module (UCM) communication card(s) to make sure that the communication options are as ordered.

BMTW-SVN01F-EN 31

Page 47

Chapter 2 BCU Mounting and Power Wiring

3. Check card locations to assure they are in the communication module slot(s) corresponding to UCM communication link wiring on TB1.

4. Locate the four snap-clip receptors on the BCU metal back panel and align with the four snap clips on the BCU logic board assembly.

5. Firmly press the two upper snap clips, then the two lower snap clips, on to the receptors. Make sure the BCU logic board assembly is fully secured to the BCU back panel.

6. With the ac power off, connect the plug from the power transformer to TB1 on the upper right corner of the BCU board card.

BCU Warning Labels

A supply of warning labels (form number X39001257-01) is shipped with each BCU (see Figure 9). Use these labels to warn operating, maintenance, and service personnel about the potential hazards associated with automatically controlled equipment.

Before making any control wiring connections, place one or more labels in conspicuous locations on each piece of controlled equipment.

Figure 9. BCU warning label

Installing and Removing the BCU Cover

Chapter 2 BCU Mounting and Power Wiring

4. Ensure that the BCU has been mounted in the recommended location and at the recommended height as shown in Figure 5 on page 18.

Note:

If the BCU is not installed as recommended, you may not be able to view and use the operator display most effectively.

5. Ensure that the BCU is a BMTW model manufactured after July 1, 2000, and has a serial number greater than E00G5000.

Note:

If the BCU was manufactured before the indicated date, the BCU logic board will not have the P13 operator display socket.

6. Make sure the power to the BCU is off.

CAUTION Possible Equipment Damage!

Failure to turn off power may result in damage to internal components.

7. Attach one end of the ribbon cable into P2, the 10-pin socket located at the top of the operator display circuit board.

Note:

The 10-pin plug on each end of the ribbon cable has a “polarizing key” to prevent improper installation of the ribbon cable. Align this polarizing key with the slot in the 10-pin socket.

Note:

When installed, the plug on one end of the ribbon cable routes the cable away from the circuit board while the plug on the other end routes the ribbon cable toward the circuit board. Use the end that routes the ribbon cable away from the circuit board.

8. Locate the small manila envelope that shipped with the BCU operator display. This envelope contains four 8 mm M4 screws and star washers.

9. Thread one screw into the threaded hole on the upper-left side of the BCU chassis (see Figure 11 on page 35). Do not completely tighten the screw.

Figure 12. Operator display socket

Operator display socket

Note:

The operator display emits a beep every 10 minutes if the operator display is powered up and either the BCU is not configured or communication has been lost between the BCU and the operator display. Therefore, if you are installing the operator display on a BCU that has not been configured, the operator display will beep. You may want to wait to power up the operator display until the BCU has been configured. To do so, simply keep the ribbon cable disconnected from the P13 operator display socket on the BCU logic board.

IMPORTANT

The operator display will not function properly if the mini-monitor is plugged into P6 on the BCU logic board. (The mini-monitor is software and cabling that allows you to view BCU information on an attached PC.) If you need to attach the mini-monitor cable, first unplug the operator display from the P13 operator display socket on the BCU logic board.

BCU I/O Module

The BCU input/output (I/O) module is an optional board that adds capabilities for five universal inputs (UIPs) and one binary output (BOP) to the BCU.

Each UIP can be configured for any of the following:

• Binary (switches or outputs)

• Current (0–20 mA)

• Pulse meter (water, gas, and electric)

• Temperature sensor (Trane thermistors)

• Voltage (0–10 Vdc) inputs

Both the hardware jumper selection and the software configuration set the UIP type.

A BOP has been included in the BCU I/O module to provide a convenient single output. The BOP can be used to control equipment or provide status information such as an alarm condition.

BCU I/O Module Installation

Install the BCU I/O module into the BCU enclosure. Refer to Figure 2 on page 4 for BCU I/O module installation location. Two posts and two screws secure the board into the back of the enclosure.

A RJ45 cable is provided to connect the BCU I/O module to the BCU. Refer to Figure 2 on page 4 for RJ45 connector locations and cable diagram. The BCU will communicate with and provide power to the BCU I/O module through this cable.

I/O Wiring

All wiring must conform to national and local electrical codes. Analog wiring should not exceed a run length of 300 ft (91 m). Binary wiring should not exceed a length of 1,000 ft (305 m). If the recommended lengths are exceeded, the wire may pick up EMI/RFI, which would affect operation of the BCU I/O module.

For input and output wiring, Trane recommends using a plenum wire that is 18–22 AWG (1.02–0.643 mm conductor is stranded, tinned copper. Only one end of the shielded wire should be grounded. At the BCU end, connect the wire’s shield to the negative lead input. On the other end of the wire, cut back and tape the shielding.

Chapter 3 BCU I/O Module

Both input wiring and output wiring are connected to the terminal block TB1 on the BCU I/O module. The five UIPs are labeled UIP1 through UIP5. The BOP is labeled BOP1. The BCU I/O module also has a 24 Vac (100 mA) output to power transmitting devices. Odd numbered terminals on TB1 are positive leads, and even numbered terminals are negative leads, except for TB1-14. For current or voltage devices, always connect the positive wire to positive leads and the negative wire to negative leads. Refer to Figure 13 for terminal locations on TB1.

Hardware UIP Selection

Each UIP has a set of hardware jumpers. Use the hardware jumpers on the BCU I/O module to specify the input device type that the UIPs will be configured for. The five UIP jumper sets are labeled UIP1 through UIP5. Refer to Figure 13 on page 38 for jumper locations. Table 5 on page 39 lists input device types for each UIP along with their corresponding jumper configurations, operating ranges, and circuit characteristics.

Binary/Pulse Meter Configured UIPs

Binary and pulse meter devices connected to binary configured UIPs must be isolated and have ungrounded contacts. Binary hardware that can be used includes momentary contact switches (normally open), standard (maintained) switches, and pulse metered devices (gas, water, or electric).

Common devices are enthalpy switches, differential-pressure airflow switches, system shutdown switches, remote alarms, photocell, gas meters, water meters, and electrical demand meters.

For pulse meter devices, the closure pulse rate may range from 0 to 4 Hz. On a contact closure, the minimum contact dwell time must last at least 125 ms for the closure to be recognized by the input.

For all UIPs in the BCU I/O module, you must create and set up the necessary objects that will provide units, calculation, and alarming to the desired input. Refer to the System Programming guide for creating and setting up the necessary objects.

Figure 14 shows the typical wiring diagram to a Trane temperature sensor with cancel and timed override buttons. There are two properties that will show whether the cancel or timed override buttons have been selected (turned on for 2 minutes). Note the polarity of the connections to the sensor.

Figure 14. Temperature Sensor Wiring Diagram

For all UIPs in the BCU I/O module, you must create and set up the necessary objects that will provide units, calculation, and alarming to the desired input. Refer to the Tracer Summit System Programming guide for creating and setting up the necessary objects.

Current and Voltage Configured UIPs

UIPs can be set up for either current or voltage input for transmitting and sensor devices that are either current or voltage sources. For current sources, the input can handle a range from 0–20 mA. The current source must be able to drive 200 Ω. For voltage sources, the input can handle a range from 0–10 Vdc. The voltage source must be able to drive 9000 Ω.

The BCU I/O module provides a 24 Vdc (100 mA) power supply output for transmitting devices that require an external dc-power supply. Refer to Figure 15 on page 43 for a wiring diagram on how to connect the power supply to a transmitting device and an input.

Note:

The 24 Vdc power supply shares a common negative input with the UIPs. This eliminates the need to connect a 24 Vdc negative power output to the negative input of the UIP.

Installing UCM Communication Cards

You can install a card in any of the four slots on the BCU.

To Install a UCM Communication Card:

1. With power turned off at switch S1, align the card with the electronic components facing toward the bottom of the BCU. Then slowly insert the card into the slot at a 45-degree angle until the card is seated.

2. Slowly move the card from the 45-degree angle to 0 degrees (horizontal), leaving the card perpendicular to the BCU logic board.

Figure 21. Comm5 UCM Communication Card

3. Secure the card using the two clips on each side of the slot.

For an illustration of how to install a UCM communication card, see Figure 22 on page 53.

Chapter 4 UCM Communication-Link Wiring

Communication-Link Wire

All Tracer Summit communication-link wiring is low voltage Class 2 and must be field-supplied and installed in compliance with NEC and local codes. To prevent electrical noise interference, all communication-link wiring must also comply with the requirements outlined in this section for wire selection and individual link configuration. Fiber-optic UCM communication is also available where extreme distance, electrical noise immunity, or building-to-building communication is required (See “FiberOptic UCM Communication” on page 64).

Do not run communication-link wiring in the same conduit or wire bundle with ac-power wires. This could cause the BCU to malfunction due to electrical noise.

Typical UCM communication-link field wiring is illustrated in Figure 23 on page 55.

Figure Note:

If unshielded wire is used (as recommended for Comm5), there is no shield connection.

UCM Communication-Wire Characteristics

(This section applies only to Comm2, Comm3, Comm4 wire.)

UCM communication-link wiring must be low-capacitance, 18-gauge, shielded, twisted pair with stranded, tinned-copper conductors. For daisy chain and branch configurations, limit the wire run length to 5,000 ft (1,524 m).

Wire capacitance (measured in picofarads/foot [pF/ft] or picofarads/meter [pF/m]) between conductors must be 23±2 pF/ft

BMTW-SVN01F-EN 55

Page 71

Chapter 4 UCM Communication-Link Wiring

(72±6 pF/m). Trane wire 400-2028 is recommended. Consult your local Trane sales office.

Comm5 UCM Communication-Wire Characteristics

The recommended Comm5 communication wiring is 22-gauge, Level 4, twisted-pair wire, either shielded or unshielded. However, you can also use low-capacitance, 18-gauge, shielded, twisted-pair with stranded, tinned-copper conductors (Trane “purple” wire).

Comm5 links should use the daisy chain configuration. The wiring run length should be limited to 4,500 ft (1,400 m) with no more than eight zone sensor communication stubs (maximum 50 ft). The links should not be a star, or trunk and branch configuration.

Recommended Configurations for UCM Communication-Link Wiring

UCM communication-link wiring must use one of the following configurations:

• Daisy chain configuration, shown in Figure 24.

• Daisy chain configuration for Comm5, shown in Figure 25 on page 57.

• Branch configuration, shown in Figure 26 on page 58.

(This configuration should not be used with Comm5 communication links.)

Termination Resistance Placement for Comm5 Links

To correctly install a Comm5 link, termination resistors are required.

At each end of link

For correct termination placement, follow the guidelines below:

• Terminate a daisy chain configuration with a resistor at each end of

the wire (105 Trane “purple” wire).

Ω. for 22 AWG, Level 4 wire and 82 Ω. for18 AWG,

• If a repeater is used, each link of the configuration that is created by

the repeater requires termination resistors (see “Alternate Daisy Chain Resistor Placement” on page 60).

• Trane recommends that only one type of wire should be used for the

Comm5 communication link.

• A set of as-built drawings or a map of the communication wire layout

should be made during installation. Any sketch of the communication layout should feature the terminating resistor placement (see Figure 27 and Figure 28 on page 60 for daisy chain configurations).

Comm5 Physical Link Repeater

The Comm5 link repeater is a device that repeats and regenerates the signal on a Comm5 link. The Comm5 link goes from the BCU to the repeater and a second link segment extends from the other side of the repeater to the rest of the devices. The configurations on either side of the repeater should be daisy chain. Both link segments require proper termination.

Communication-Link Wire

When is the Link Repeater Required?

A link repeater is required when:

• The total wire length is greater than the maximum wire run length of

4,500 ft (1,400 m).

• More than 60 devices are connected to a link. This total does not

include the BCU, the link repeater, and the temporary use of the Rover service tool on the same link.

• More than eight zone sensor communication stubs (maximum 50 ft)

are required on a Comm5 link (see “Zone Sensor Communication Stubs” on page 144).

Link Repeater Limitations

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 configuration, the total wire length can be 9,000 ft (2,800 m) (with half the wire length on either side of the repeater).

• The link repeater is limited to 60 devices on either side of the link.

The total number of devices that can be attached to a repeater is 120.

• The link repeater requires a definite earth ground. The installer

should be aware of this before making any power connections.

Link Repeater Connections

Recommended shield connections are shown in Figure 29 on page 62. Figure 30 on page 63 is an example of using a repeater to create an extended daisy chain configuration.

Follow these guidelines when using a repeater:

• Read the Comm5 repeater installation, 3270 3285 information that

comes with the link repeater.

• For information about terminating daisy chain configurations, see

“Termination Resistance Placement for Comm5 Links” on page 59.

• For information about shielded cable connections, see “Recommended

Wiring Practices” on page 64.”

• Shield-drain wires entering the repeater should be connected to a ter-

minal marked with a capacitor symbol. The entering shield-drain wire must be connected to earth ground at the BCU.

• Shield-drain wires leaving the repeater should be connected to the

repeater terminal marked with an earth ground symbol.

Chapter 4 UCM Communication-Link Wiring

Recommended Wiring Practices

The following guidelines should be followed while installing communication wire:

• Although Comm5 does not require polarity sensitivity, Trane recom-

mends that the installer keep polarity consistent throughout the site.

• Only strip away 2 inches maximum of the outer conductor of shielded

cable.

• Make sure that the 24 Vac power supplies are consistent in how they

are grounded. Avoid sharing 24 Vac between Comm5 UCMs.

• Avoid overtightening cable ties and other forms of cable wraps. This

can damage the wires inside the cable.

• Do not run Comm5 cable alongside or in the same conduit as 24 Vac

power. This includes the conductors running from triac-type inputs.

• In an open plenum, avoid lighting ballasts, especially those using

277 Vac.

• Use a daisy chain configuration. Branch configurations are not rec-

ommended.

Fiber-Optic UCM Communication

Fiber-optic cable is used for applications involving long distances because there is little degradation of optic signals, and the integrity of the signal is maintained in the presence of several sources of electrical noise, including lightning, EMI/RFI, voltage conductors, and ground loops.

Trane requires duplex, 62.5 µm core glass fiber-optic cable with ST connectors. There are a variety of cables available for different applications including indoor, outdoor, burial, aerial, and duct.

You can order fiber-optic cables, fiber-optic modems, ST-type crimp connectors, epoxy connectors, and other accessories from Trane through the Buying Group.

Typically, the fiber-optic UCM communication link is used in applications where a BCU located in one building communicates not only to the UCMs within that building, but also to other UCMs located in other buildings. The fiber-optic cable is used typically as the communication link between buildings, and it uses EIA-485 data transceivers (D1300) and EIA-485 data repeaters (D2300), which are called fiber-optic modems. These modems convert the electrical signals from a twisted pair of wires to optical signals, which are sent over the fiber-optic cable. At the other end, the optical signals are converted back to electrical signals and sent along the twisted pair of wires.

IMPORTANT

Trane recommends that only qualified and experienced fiber-optic technicians prepare the fiber-optic end connectors and cable run lengths. Improper methods may result in faulty communication due to signal

64 BMTW-SVN01F-EN

Page 80

Fiber-Optic UCM Communication

degradation (decibel loss). The signal degradation must be less than 14 dB on each fiber.

Note:

Use fiber-optic cable for long distances, interbuilding cabling, and/or other high electrical noise areas such as petrochemical installations, electronic rooms, and near hospital NMR or X-ray rooms.

Fiber-Optic Modems

The EIA-485 data transceiver (D1300) has one fiber-optic port and one twisted-pair (EIA-485) port. The EIA-485 data repeater (D2300) has two fiber-optic ports and one twisted-pair (EIA-485) port. Each fiber-optic port has two connections, one for transmitting information and one for receiving information.

An illustration of a D2300 fiber-optic modem and the connections to it is provided in Figure 31. The EIA-485 data transceiver (D1300) looks like the EIA-485 data repeater (D2300) shown in this figure, but it has only one fiber-optic port. The mounting and power wiring is the same for both types of fiber-optic modems.

Figure 31. EIA-485 Data Repeater (D2300) Fiber-Optic Modem

Mounting and Wiring Fiber-Optic Modems

1. Mount the fiber-optic modem on the wall using the four mounting screw holes on the modem.

2. Connect power to the modem using the ac adapter provided with the modem. The adapter has two wires; one black with a white stripe, and one solid black. The white striped wire connects to the 12 Vac/Vdc connection on the modem, and the solid black wire connects to the ground (GRD-2) terminal.

BMTW-SVN01F-EN 65

Page 81

Chapter 4 UCM Communication-Link Wiring

3. Verify that a proper connection is made by plugging the ac adapter into an electrical outlet and viewing the red power LED on the left side of the modem. If the red LED does not illuminate, check the polarity of the connection and verify that the electrical outlet is powered.

4. Connect the terminated fibers, making sure that the fiber going to DATA REC on the next modem goes to DATA XTMR on this modem and vice versa. Keep track of the polarity by recording the color of the jacket on each fiber and to which connection it goes on each building.

IMPORTANT

Fiber-optic polarity is extremely important! Make sure that the fiber connections on the fiber-optic modem are reversed for the next modem, and then reversed again to the next modem, and so on.

5. Connect the UCM communication link and the resistor (provided with the modem) to the modem as shown in Figure 31 on page 65. Connect the shield at the BCU end and tape it back at the modem end. Polarity of this connection is important only for Comm4 cards.

Exception: In buildings that do not have a BCU, the shield from the communication-link wiring must be grounded on the GRD-2 terminal between the two UCM communication-link wire terminals of the fiber-optic modem. The shield wire must not touch either of the two communication wires.

A typical application using twisted-pair communication wire between the BCU and UCMs within the initial building, then connected to several other buildings using fiber-optic modems, is shown in Figure 32 on page 67.

66 BMTW-SVN01F-EN

Page 82

Fiber-Optic UCM Communication

Figure 32. Typical Fiber-Optic UCM Communication-Link Layout

Optical-Link Loss Budget

Every fiber-optic link has some signal loss (measured in decibels). Many factors affect decibel loss, including:

• Length of fiber-optic cable

• Transmitter optical output power

• Operating wavelength

• Fiber attenuation

• Fiber bandwidth

• Receiver optical sensitivity

The decibel loss between any two devices is based on how well the terminations or splices are made. A termination or splice can vary from

0.5–2 dB loss. A clean splice results in increased performance.

The fiber-optic modem supported by Trane has a power budget of 14 dB between 32°F and 140°F (0°C and 60°C). This is the acceptable temperature range specified for the BCU. The decibel loss for conduit-rated fiberoptic cable (P/N 400-4002) is 3.75 dB/km (1 km = 3,280 ft). Precut fiber-

BMTW-SVN01F-EN 67

Page 83

Chapter 4 UCM Communication-Link Wiring

optic cables and professionally spliced and/or terminated cables should ensure minimal decibel loss.

To calculate the system loss, subtract the cable loss, splice loss, terminator loss, and patch panel loss from the power budget. The example below shows typical values for the UCM communication link.

power budget – system safety margin = available budget

14 dB – 3 dB = 11 dB (available budget)

available budget: 11 dB

cable loss: – 7.5 dB (1 km at 3.75 dB/km)

allowance for splice loss: – 1 dB (2 at .5 dB)

allowance for end connectors: – 1 dB (2 at .5 dB)

allowance for patch panel: – 1 dB (2 at .5 dB)

excess margin: = 0.5 dB

UCM Wiring and Addressing

Unit control modules (UCMs) provide the communication interface necessary for a BCU to monitor and control equipment. In this section, each UCM is described in terms of the equipment it is used with and the type of card that provides the communication link.

Addresses for most UCMs are set by using DIP switches or local displays. In this section, specific tables provide address settings for each of these UCM types. Appendix A provides an alternative table, along with calculation instructions, that can be used for all DIP switch settings.

Comm5 UCMs are unique because they do not have a field-configurable DIP switch address (see “Neuron ID” on page 144).

CenTraVac Unit Control Panel (UCP1) Interface

CenTraVac unit control panels (UCP1s) allow a Tracer Summit system to monitor and control the following CenTraVac control chiller models: CVHE, CVAD, CVHB, and RTHA. One digit of each UCP1’s model number indicates whether the UCP1 has a bidirectional communication interface and can communicate with Tracer Summit.

For CVHE, CVAD, and CVHB chillers, the UCP1 must have a code number of 13650396-06 or higher and also have the following model number specification:

• If the UCP1 model number has 41 digits, digit #38 must be the letter

W or Z.

• If the UCP1 model number has 18 digits, digit #14 must be the

letter B.

For RTHA chillers, the UCP1 must have a code number of 13650396-06 or higher and digit #13 of the UCP1 model number must be the letter D.

Note:

If the UCP1 control panel is connected to a System Control Panel (SCP), with or without a Tracer 100 in place, then the chiller has a bidirectional communication interface (regardless of the chiller model number). The SCP can be removed and the chiller can be connected to a Tracer Summit system for monitoring and control.

For specific information about the number of UCP1s allowed per BCU and per communication link, refer to Table 7 on page 46.

Type of Communication Card: Comm2

Refer to “Comm2 Card” on page 48.

Wiring Notes

To establish wiring connections between the UCM and the BCU, Trane requires that you use the communication-link wiring specified in this manual. For wire selection specifications, see “UCM CommunicationWire Characteristics” on page 55.

Use fiber-optic modems for building-to-building communication. If fiber optics are not used, building-to-building communication wiring requires a Transtector transient protector at each building. You can purchase Transtector protectors through Trane. Contact your local Trane sales office for details.

In a daisy chain configuration, use one pair of wires that start at the BCU and go to all UCMs in a continuous loop. A branch configuration is possible if you need to tap into a daisy chain. Limit the total aggregate length of the wiring for each communication link to 5,000 ft (1,524 m).

To connect communication wiring:

1. Attach one end of the communication-link wiring to TB2 on the BCU. For the location of TB2 refer to Figure 16 on page 47.

2. Attach the other end of the communication-link wiring to the UCP at the 1TB6 terminal on the 1U3 module of the UCP. Refer to the UCP literature for details concerning UCP installation and operation.

To connect the shield:

◆ Connect the shield at the BCU (TB2) to provide a drain for RFI/EMI,

and then splice it with other UPC1 UCM shields at the UPC1 UCM end. Tape the shield at the last UPC1 UCM in the chain to prevent any connection between the shield and ground (see Figure 33 on page 71).

Note:

Observe the polarity throughout communication links.

IMPORTANT

UCM ground loops will cause a malfunction.

Horizon Absorption Chiller Interface

Description

Tracer Summit can monitor, control, and configure Horizon absorption chillers. The Horizon interface provides a communication link between each Horizon absorption chiller and the BCU. For specific information about the number of Horizons allowed per BCU and per communication link, refer to Table 7 on page 46.

Absorption chillers manufactured in China and known by the names Dragon and Navigator also are controlled and monitored using this interface. This section refers only to the Horizon chillers, but applies to the Dragon and Navigator chillers as well unless specifically stated.

You must configure the menu items on the UCM for proper Tracer Summit operation according to Table 12.

stector protectors through Trane. Contact your local Trane sales office for details.

To connect communication wiring:

◆ Attach one end of the communication-link wiring to TB2 on the BCU.

For the location of TB2, refer to Figure 16 on page 47. The communication-link wiring must be connected to the TCI4-Comm4 module on the communication-link terminal block (J3-A or J3-B)

To connect the shield:

Connect the shield at the BCU (TB2) to provide a drain for RFI/EMI, and then splice it with other Horizon shields at the Horizon end. Tape the shield at the last Horizon in the chain to prevent any connection between the shield and ground (refer to Figure 39). If polarity is reversed and the BCU is both configured and connected, the green RX light on the TCI4Comm4 board will be ON solid.
