Warnings, Cautions, and Notices

Read this manual thoroughly before operating or servicing this unit. Safety advisories appear throughout this manual as required. Your personal safety and the proper operation of this machine depend upon the strict observance of these precautions.

The three types of advisories are defined as follows:

WARNING Indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury.
CAUTION Indicates a potentially hazardous situation that, if not avoided, could result in minor or moderate injury. It could also be used to alert against unsafe practices.
NOTICE Indicates a situation that could result in equipment or property damage only accidents.

Important Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the earth’s naturally occurring stratospheric ozone layer when released to the atmosphere. In particular, several of the identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine, Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon (HCFCs). Not all refrigerants containing these compounds have the same potential impact to the environment. Trane advocates the responsible handling of all refrigerants including industry replacements for CFCs such as HCFCs and HFCs.

Important Responsible Refrigerant Practices
Trane believes that responsible refrigerant practices are important to the environment, our customers, and the air conditioning industry. All technicians who handle refrigerants must be certified according to local rules. For the USA, the Federal Clean Air Act (Section 608) sets forth the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and the equipment that is used in these service procedures. In addition, some states or municipalities may have additional requirements that must also be adhered to for the responsible management of refrigerants. Know the applicable laws and follow them.

WARNING

Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury. All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazads, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state/national electrical codes.

WARNING

Personal Protective Equipment (PPE) Required!
Failure to wear proper PPE for the job being undertaken could result in death or serious injury. Technicians, in order to protect themselves from potential electrical, mechanical, and chemical hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well as the instructions below:

Before installing/servicing this unit, technicians MUST put on all PPE required for the work being undertaken (Examples; cut resistant gloves/sleeves, butyl gloves, safety glasses, hard hat/bump cap, fall protection, electrical PPE and arc flash clothing). ALWAYS refer to appropriate Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.
When working with or around hazardous chemicals, ALWAYS refer to the appropriate SDS and OSHA/GHS (Global Harmonized System of Classification and Labeling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection and handling instructions.
If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other country-specific requirements for arc flash protection, PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE ELECTRICAL METERS AND EQUIPMENT ARE PROPERLY RATED FOR THE INTENDED VOLTAGE.

WARNING

Follow EHS Policies!
Failure to follow the instructions below could result in death or serious injury.

All Trane personnel must follow the company’s Environmental, Health and Safety (EHS) policies when performing work such as hot work, electrical, fall protection, lockout/tagout, refrigerant handling, etc. Where local regulations are more stringent than these policies, those regulations supersede these policies.
Non-Trane personnel should always follow local regulations.

Note:
If all devices cannot be powered on at the same time, the best practice is to power them on in the following order:

All WCIs
All Tracer® SCs
All Controllers
All WCSs

Identifying the Network Coordinator

Identifying the Network Coordinator (One per Network) and Initiating Network Formation

If a Tracer®SC/SC+ is present when the WCI is powered:

The WCI that is wired to Tracer® SC/SC+ becomes the network coordinator and network formation is initiated.
The network automatically opens and remains open for 60 minutes.
The LEDs illuminate on the network coordinator as shown. See Table 1 for details.

If no Tracer® SC/SC+ is present when the WCI is powered:

Identify a centrally located WCI to be the network coordinator.
Manually open the network by pressing the Start button for 5 seconds on the WCI that is to be network coordinator. The WCI becomes network coordinator and network formation is initiated.
Observe the LEDs on the network coordinator. See Table 1 for details.

The Network Forms

The NWK LED illuminates on every WCI that joins the network.

Notes:

Network automatically stays open 1 hr. After each WCI joins, the 1 hr. timer starts over. If time expires, press OPEN NET to re-open the network.
The coordinator opens all WCIs in the network. A member WCI can only open itself for 10 minutes.

Triple flash pattern

| Failed to join network. Occurs for 30 seconds after failing to join a network. Will continue this pattern until successful join.

Corrective Action: Insure network is formed and open, then allow time for WCI to join on its own.

Double flash pattern

| • Normal for a repeater.

• WCI lost IMC communication to the UC/BCI/Tracer ® SC/SC+.

Corrective action: Check IMC wiring, then cycle power to the controller/WCI to establish communication.

• WCI was not configured correctly. (WCI did not get BACnet ID from UC/BCI/SC/SC+, and/or WCI did not get rotary address from the UC/BCI/SC/ SC+.)

Corrective Action: Cycle power to the controller/WCI.

Power LED (green)

PWR

| On solid Off| WCI has power.

WCI does not have power.

Corrective Action: Check WCI power wiring for 24v DC or AC.

LED will flash steady (about 3 flashes per second) on WCI that was built prior to 2019.
LED will appear to be on steady for WCI built 2019 and after. Will appear dim and flicker occasionally according to how much data is passing.
LED is off for all WCI.
If more than one condition is present, the priority is in the order listed.
