Introduction

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 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 and HCFCs such as saturated or unsaturated HFCs and HCFCs.
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.

SS-SVX007B-EN

Overview
Occupancy Switch Notes (AHU)
· An occupancy switch must be field wired to 7TB2-12 and 7TB2-13 for proper operation. · When the occupancy switch is closed the unit will be occupied. When the occupancy switch is open
the unit will be unoccupied. · Occupancy may be communicated to the unit via Multi-state Value 2, but the unit control must be set
to BAS. See points list for additional details.
Outdoor Air Temperature Sensor Notes (AHU and Chiller)
· The outdoor air (OA) sensor is factory wired to the UC controller and is supplied with enough wire to reach the mounting point.
· Use the bracket that is included in the unit to mount the OA sensor to the air entering side of the condenser coils.
Occupied Sequence of Operation (AHU)
1. Thermostat Control Units: Fan operation must be proven via contact closure across terminals 7TB2-3 and 7TB2-4. Once fan is proven and the unit is in occupied mode, a field-supplied thermostat or sequencer will call on compressors with contact closures across universal inputs UI1 to UI6. Normally, open contacts for compressor staging will be wired to terminals 7TB2-5 to 7TB2-11 for cool calls 1 to 6, respectively.
2. Constant Air Volume (CV) Control Units: Fan operation must be proven via contact closure across terminals 7TB2-3 and 7TB2-4. A fieldinstalled space temperature sensor with setpoint (BAYSENS075A) must be wired to 7TB2-16 to 7TB218 according to the wiring diagram. Once fan is proven and the unit is in occupied mode, the compressors will be controlled by the Tracer UC600 to maintain space temperature at setpoint.
3. Variable Air Volume (VAV) Control Units: Fan operation must be proven via contact closure across terminals 7TB2-3 and 7TB2-4. A fieldinstalled discharge air temperature sensor (10K, Type II thermistor) must be wired to 7TB2-14 and 7TB2-15 according to the wiring diagram. Once fan is proven and the unit is in occupied mode, the compressors will be controlled by the Tracer UC600 to maintain discharge air temperature at setpoint. Default value is 55°F.
Supply Fan Control Notes (AHU)
The supply fan is controlled by others. Fan status must be hardwired to the Tracer UC600 across terminals 7TB2-3 and 7TB2-4 for proper operation.

Overview
General Control Notes (AHU)
· Unit controls shall maintain minimum on and off timers to protect compressors from short cycling. · Factory safeties (for example, High/Low pressure, temperature) are re-wired to allow for monitoring
and diagnostic capability with the Tracer UC600. The only factory components that are replaced by the DDC controller are compressor on/off timers. · In unoccupied cooling mode, this unit will stage compressors to maintain temperature at unoccupied cooling setpoint. · The Tracer UC600 will monitor safety status and lock out compressors if a safety trips three consecutive times in one hour. This hard lockout must be reset by cycling power to the unit. A soft lockout will occur if a high-pressure or low-pressure safety trips and will shut the circuit's compressors off for at least three minutes. The safety resets itself. · Tracer UC600 will maintain a 3-minute inter-stage timer when ramping stages of cooling up and down. · Cool Calc P-Gain may need to be adjusted on startup to optimize cooling operation.

Startup Instructions

AHU

1. The mode of operation (Thermostat, CV or VAV) is determined by jumpers J1 and J2 on UI9 and UI10. Control selection is made according to the following:
a. If J1 and J2 are either both in place or both removed, the unit will operate as Thermostat controlled and Compressors will be enabled/disabled based on inputs UI1 UI6 according to the wiring diagrams.
b. If J1 is removed or cut and J2 remains in place, the unit will operate as Constant Volume (CV) and the compressors will be controlled to satisfy space temperature at local setpoint.
c. If J1 is in place and J2 is removed or cut, the unit will operate as Variable Air Volume (VAV) and the compressors will be controlled to satisfy discharge air temperature at setpoint. A discharge air temperature sensor (10k Type II thermistor) is required for the unit to operate correctly. See wiring diagram.

2. Once the new panel is installed, wiring reconnected and mode of operation set, restore power to the unit and verify correct operation.
3. Because the refrigeration safeties were rewired through a relay and UC monitoring, each safety should be checked for wiring accuracy. Circuit compressors will be locked out after three safety trips within a one-hour period. Power must be cycled off and on at the unit disconnect to reset the hard lockout.
a. Pull wire on Circuit 1 High Pressure Cutout (4S1) and verify relay 7K8 relay denergizes, and circuit 1 compressor(s) shut down immediately.
b. Pull wire on Circuit 1 Low Pressure Cutout (4S5) and verify relay 7K9 relay deenergizes, and circuit 1 compressor(s) shut down immediately.
c. Pull wire on Circuit 2 High Pressure Cutout (4S2) and verify relay 7K10 relay deenergizes, and circuit 2 compressor(s) shut down immediately.
d. Pull wire on Circuit 2 Low Pressure Cutout (4S6) and verify relay 7K11 deenergizes, and circuit 2 compressor(s) shut down immediately.
e. Remaining split-system RAUJ will follow standard startup procedure.

1. Once the new panel is installed, wiring reconnected and mode of operation set, restore power to the unit and verify correct operation. Do not enable unit yet!
2. Verify the Freeze Setpoint (Analog Value 10) is set to an appropriate value for the fluid type being used in the chiller. Default value is 36°F for straight water.
3. Verify the Low Ambient Lockout Setpoint is set to the proper value. Default value is 40°F. This value may be adjusted lower if low ambient damper option is installed. Setpoint adjustment is accomplished by adjusting analog constant in the "Setpoints" program.
4. Since the refrigeration safeties were re-wired through a relay and UC monitoring, each safety should be checked for wiring accuracy. Circuit compressors will be locked out after 3 safety trips within a 1hour period. Power must be cycled off and on at the unit disconnect to reset the hard lockout.
a. Pull wire on Circuit 1 High Pressure Cutout (4S1) and verify relay 7K8 relay deenergizes, and circuit 1 compressor(s) shut down immediately.
b. Pull wire on Circuit 1 Low Pressure Cutout (4S5) and verify relay 7K9 relay deenergizes, and circuit 1 compressor(s) shut down immediately.
c. Pull wire on Circuit 2 High Pressure Cutout (4S2) and verify relay 7K10 relay deenergizes, and circuit 2 compressor(s) shut down immediately.
d. Pull wire on Circuit 2 Low Pressure Cutout (4S6) and verify relay 7K11 deenergizes, and circuit 2 compressor(s) shut down immediately.
5. Enable Circulating pump and verify 7K1 relay energizes. If 7K1 does not energize, verify all field installed safeties (flow switch, freezestat, motor overloads, etc.) are not tripped and wired properly.
6. After a few moments the Tracer UC600, Cool Calc should start ramping up and enabling compressors. The Cool Calc P-Gain (Analog Value 3) may need to be adjusted based on water flow, chiller load, to avoid excessive cycling or over/undershooting setpoint.
7. Remaining chiller startup will follow standard RAUJ startup procedure.
