SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation,
starting up, and servicing of heating, ventilating, and air-conditioning equipment
can be hazardous and requires specific knowledge and training. Improperly
installed, adjusted or altered equipment by an unqualified person could result in
death or serious injury. When working on the equipment, observe all precautions in
the literature and on the tags, stickers, and labels that are attached to the
equipment.

The circuit board for the Tracer MP581 programmable controller can be
used to upgrade Tracer AH540/541 controllers to Tracer MP580/581
controllers. It also replaces inoperative Tracer MP580/581 circuit boards.
Note: The replacement circuit board does not look exactly like the board
you are replacing. The replacement board has eyelets on its bottom side
and possible other small differences.
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.
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 responsible
management of refrigerants. Know the applicable laws and follow them.
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
NOTICE Indicates a situation that could result in
equipment or property-damage only accidents.
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 electrical codes.
WARNING
Personal Protective Equipment Required!
Installing/servicing this unit could result in exposure to electrical, mechanical
and chemical hazards. Before installing/servicing this unit, technicians MUST
put on all Personal Protective Equipment (PPE) recommended for the work
being undertaken. ALWAYS refer to appropriate SDS sheets and OSHA
guidelines for proper PPE. When working with or around hazardous chemicals,
ALWAYS refer to the appropriate SDS sheets and OSHA guidelines for
information on allowable personal exposure levels, proper respiratory
protection and handling recommendations. If there is a risk of arc or flash,
technicians MUST put on all necessary Personal Protective Equipment (PPE) in
accordance with NFPA70E for arc/flash protection PRIOR to servicing the unit.
Failure to follow recommendations could result in death or serious injury.

Removing Existing Circuit Board
1. Disconnect the 24 Vac power cable from the termination board.
2. Remove the grounding screw from the lower right-hand corner of the
circuit board if it is installed.
WARNING
Hazardous Voltage!
Disconnect all electrical power, including remote disconnects, before servicing.
Follow proper lockout/tagout procedures to ensure the power cannot be
inadvertently energized. Failure to disconnect power before servicing could
result in death or serious injury.

3. Unsnap the top plastic frame holding the circuit board from the
bottom frame.
4. Disconnect the 20-pin cable from the 20-pin slot, then disconnect the
60-pin cable from the 60-pin slot.
5. On the top frame, push the two tall plastic pieces that hold the circuit
board in place away from each other.
6. Remove the circuit board from the frame.
Installing New Circuit Board
1. Place the circuit board on the top plastic frame.
2. Push down on the circuit board until it snaps into place.
3. Disconnect the 24 Vac power cable from the termination board.
4. Hold the top frame at a 90° angle to the bottom frame as shown
below.
5. Connect the 60-pin cable to the 60-pin slot, then connect the 20-pin
cable to the 20-pin slot.The connectors are keyed to the slots. Ensure
that the keys are lined up with the slots.
6. Align the snaps on the top frame with the mounting locks on the
bottom frame and then push the two frames together until it clicks.
7. For controllers with an operator display, connect the operator-display
