Introduction

Read this manual thoroughly before operating or servicing this unit.

Warnings, Cautions, and Notices
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 which, if not avoided, could result in death or serious injury.
• CAUTION Indicates a potentially hazardous situation which, 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 resu lt 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.

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 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 hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state/national electrical codes.

General Information

The information provided in this manual is intended for use when adding human interface support to a Precedent™ or Voyager™ Light Commercial unit that has ReliaTel™ controls. The work involved in this upgrade consists of the following:

• Updating to the latest ReliaTel Refrigeration Module (RTRM) to MOD02703
• Installing the TD-5 human interface mounting bracket
• Mounting a TD-5 display to the human interface mounting bracket
• Connecting the TD-5 human interface cable to the RTRM

The TD-5 human interface allows you to view historic alarms, reports, graph specific data, create setpoints, and save graph data to a USB device for further diagnosis. Detailed information on the capabilities of the TD-5 can be found in the Tracer® TD-5 Display for ReliaTel™ Controller Installation, Operation, and Maintenance (RT-SVX49*-EN).
A number of setpoints can be changed by using the different potentiometers on each control board. To change the setpoint, use a screw driver to turn the potentiometers to a specific value.
Figure 3. Example of changing potentiometer value on

• To view all potentiometer setpoint values, put the TD-5 human interface in Read mode by going to Settings > Setup > Display Read Only Mode.
• In Writer mode, the TD-5 can override the setpoint values created from the potentiometers, making setpoint configuration easier.
• If the TD-5 human interface is disconnected from the ReliaTel Refrigeration Module, the local setpoints from the potentiometer are used. Note that setpoints created from a building automation system (BAS) take precedence over setpoints created by the TD-
• Additional modules are available as options that have the capability to create setpoints. Table 2 defines these optional modules:
