NOTICE

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:

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

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.

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.

The manufacturer will not assume any responsibility for equipment damage resulting from condensate accumulation on the unit’s electrical and/or mechanical components.

Unit Clearances

The Unit Dimensions section illustrates the minimum operating and service clearances for either a single or multiple unit installation. These clearances are the minimum distances necessary to assure adequate serviceability, cataloged unit capacity, and peak operating efficiency.

Providing less than the recommended clearances may result in “short-circuiting” of exhaust and economizer airflows.

Unit Description

Before shipment, each unit is leak tested, dehydrated, charged with refrigerant and compressor oil, and run tested for proper control operation.

The ReliaTel™ Control Module is a microelectronic control system that is referred to as “Refrigeration Module” (RTRM). The acronym RTRM is used extensively throughout this document when referring to the control system network.

This module through Proportional/Integral control algorithms perform specific unit functions that governs unit operation in response to; zone temperature, supply air temperature, and/or humidity conditions depending on the application. The stages of capacity control for these units are achieved by starting and stopping the compressors.

The RTRM is mounted in the control panel and is factory wired to the respective internal components. The RTRM receives and interprets information from other unit modules, sensors, remote panels, and customer binary contacts to satisfy the applicable request for cooling.

ReliaTel™™ Control

Economizer Control Actuator

The ECA monitors the mixed air temperature, return air temperature, minimum position setpoint (local or remote), power exhaust setpoint, CO and ambient dry bulb/enthalpy sensor or comparative humidity (return air humidity against ambient humidity) sensors, if selected, to control dampers to an accuracy of +/- 5% of stroke. The actuator is spring returned to the closed position any time that power is lost to the unit. It is capable of delivering up to 25 inch pounds of torque and is powered by 24 Vac.

setpoint, CO2,

RTCI – ReliaTel™™ Trane Communication Interface (Optional)

This module is used when the application calls for an ICS™ building management type control system. It allows the control and monitoring of the system through an ICS panel. The module can be ordered from the factory or ordered as a kit to be field installed. Follow the installation instruction that ships with each kit when field installation is necessary.

RLCI – ReliaTel™™ LonTalk Communication Interface (Optional)

This module is used when the application calls for an ICS™ building management type control system that is LonTalk. It allows the control and monitoring of the system through an ICS panel. The module can be ordered from the factory or ordered as a kit to be field installed. Follow the installation instruction that ships with each kit when field installation is necessary.

RBCI – ReliaTel™™ BACnet®® Communication Interface (Optional)

This module is used when the application calls for an open BACnet protocol. It allows the control and monitoring of the system through an ICS panel. The module can be ordered from the factory or as a kit to be field installed. Follow the installation instructions that ships with each kit when field installation is necessary.

RTOM – ReliaTel™™ Options Module (Optional)

The RTOM monitors the supply fan proving, clogged filter, supply air temperature, exhaust fan setpoint, supply air tempering, Frostat™ and smoke detector. Refer to system input devices and functions for operation.

Trane Air-Fi®® Wireless Communication Interface (Optional)

The Trane Air-Fi Wireless Communication Interface (WCI) allows for wireless communication between system controls, unit controls, and wireless sensors for Trane control products that use BACnet protocol. The WCI replaces the need for communications wire in all system applications.

System Input Devices & Functions

The RTRM must have a zone sensor or thermostat input in order to operate the unit. The flexibility of having several mode capabilities depends upon the type of zone sensor or thermostat selected to interface with the RTRM.

WSHP-SVX015C-EN

Page 11

GGeenneerraall IInnffoorrmmaattiioonn

The descriptions of the following basic Input Devices used within the RTRM network are to acquaint the operator with their function as they interface with the various modules. Refer to the unit’s electrical schematics for the specific module connections.

NNoottee:: The following controls are available from the

factory for field installation.

Supply Fan Failure Input (Optional)

The Fan Failure Switch can be connected to sense indoor fan operation:

FFS (Fan Failure Switch) If air flow through the unit is not proven by the differential pressure switch connected to the RTOM (factory set point 0.07 “ w.c.) within 40 seconds nominally, the RTRM will shut off all mechanical operations, lock the system out, send a diagnostic to ICS, and the SERVICE output will flash. The system will remain locked out until a reset is initiated either manually or through ICS.

Drain Pan Condensate Overflow Switch (Optional)

This input incorporates the Condensate Overflow Switch (COF) mounted on the drain pan and the ReliaTel™ Options Module (RTOM). When the condensate level reaches the trip point for 6 continuous seconds, the RTOM will shut down all unit function until the overflow condition has cleared. The unit will return to normal operation after 6 continuous seconds with the COF in a non-tripped condition. If the condensate level causes the unit to shutdown more than 2 times in a 3 day period, the unit will be lockedout of operation. A manual reset of the diagnostic system through the Zone Sensor or Building Automation System (BAS) will be required. Cycling unit power will also clear the fault."

Clogged Filter Switch (Optional)

The unit mounted clogged filter switch monitors the pressure differential across the return air filters. It is mounted in the filter section and is connected to the RTOM. A diagnostic SERVICE signal is sent to the remote panel if the pressure differential across the filters is at least 0.5" w.c. The contacts will automatically open when the pressure differential across the filters decreases to approximately 0.4" w.c. The clogged filter output is energized when the supply fan is operating and the clogged filter switch has been closed for at least 2 minutes. The system will continue to operate regardless of the status of the filter switch.

Please note that on units equipped with factory installed MERV 13 filters, a clogged filter switch with different pressure settings will be installed. This switch will close when the differential pressure is approximately 0.8' w.c. and open when the differential falls to 0.7" w.c.

Compressor Disable (CPR1/2)

This input incorporates the low pressure control (LPC) of each refrigeration circuit and can be activated by opening a field supplied contact installed on the LTB.

If this circuit is open before the compressor is started, the compressor will not be allowed to operate. Anytime this circuit is opened for 1 continuous second during compressor operation, the compressor for that circuit is immediately turned “Off”. The compressor will not be allowed to restart for a minimum of 3 minutes should the contacts close.

If four consecutive open conditions occur during the first three minutes of operation, the compressor for that circuit will be locked out, a diagnostic communicated to the remote panel (if installed), and a manual reset will be required to restart the compressor.

Low Pressure Control

ReliaTel™™ Control

When the LPC is opened for 1 continuous second, the compressor for that circuit is turned off immediately. The compressor will not be allowed to restart for a minimum of 3 minutes.

If four consecutive open conditions occur during the first three minutes of operation, the compressor will be locked out, a diagnostic communicated to ICS™ if applicable, and a manual reset will be required to restart the compressor.

High Pressure Control

ReliaTel™™ Control

The high pressure controls are wired in series between the compressor outputs on the RTRM and the compressor contactor coils. If the high pressure control switch opens, the RTRM senses a lack of current while calling for cooling and locks the compressor out.

On dual circuit units, if the high pressure control opens, the compressor on the affected circuit is locked out. A manual reset for the affected circuit is required.

Power Exhaust Control (Optional)

The power exhaust fan is started whenever the position of the economizer dampers meets or exceed the power exhaust setpoint when the indoor fan is on.

The setpoint panel is located in the return air section and is factory set at 25%.

Lead/Lag Control (Dual Circuit Only)

Lead/Lag is a selectable input located on the RTRM. The RTRM is configured from the factory with the Lead/ Lag control disabled. To activate the Lead/Lag function, simply cut the wire connected to J3-8 at the RTRM. When it is activated, each time the designated lead compressor is shut off due to the load being satisfied,

WSHP-SVX015C-EN

Page 12

GGeenneerraall IInnffoorrmmaattiioonn

the lead compressor or refrigeration circuit switches. When the RTRM is powered up, i.e. after a power failure, the control will default to the number one circuit compressor.

Evaporator Frost Control

This input incorporates the Frostat™ control (FOS) mounted in the indoor coil and can be activated by closing a field supplied contact installed in parallel with the FOS.

If this circuit is closed before the compressor is started, the compressor will not be allowed to operate. Anytime this circuit is closed for 1 continuous second during compressor operation, the compressor for that circuit is immediately turned “Off”. The compressor will not be allowed to restart for a minimum of 3 minutes should the FOS open.

Frostat™ is standard on multi-speed indoor motors and single zone VAV products (SZVAV).

Smoke Detector Sensor (Optional)

This sensor is only applicable on units equipped with a RTOM. It provides high limit “shutdown” of the unit and requires a manual reset. The sensor is used to detect smoke due to fire in the air conditioning or ventilation ducts.

The supply and return air smoke detectors are designed to shut off the unit if smoke is sensed in the supply air stream or return air stream. This function is performed by sampling the airflow entering the unit at the return air opening. Follow the instructions provided below to assure that the airflow through the unit is sufficient for adequate sampling. Failure to follow these instructions will prevent the smoke detectors from performing it's design function.

IImmppoorrttaanntt:: Airflow through the unit is affected by the

amount of dirt and debris accumulated on the indoor coil and filters. To insure that airflow through the unit is adequate for proper sampling by the return air smoke detector, complete adherence to the maintenance procedures, including recommended intervals between filter changes, and coil cleaning is required.

Periodic checks and maintenance procedures must be performed on the smoke detector to insure that it will function properly. For detailed instructions concerning these checks and procedures, refer to the appropriate section(s) of the smoke detector Installation and Maintenance Instructions provided with the literature package for this unit.

In order for the supply air smoke detector or return air smoke detector to properly sense smoke in the supply air stream or return air stream, the air velocity entering the smoke detector unit must be between 500 and 4000 feet per minute. Equipment covered in this manual will develop an airflow velocity that falls within these limits

over the entire airflow range specified in the evaporator fan performance tables.

NNootteess::

• For units with optional Condensate Overflow Switch (COF), the switch will not work properly if unit is not level or slightly sloped toward switch.

• To assure proper condensate flow during operation the unit and the curb must be level.

If the unit is installed at ground level, elevate it above the snow line. Provide concrete footings at each support location with a “full perimeter” support structure or a slab foundation for support. Refer to the Unit Weights section for the unit’s operating and point loading weights when constructing a footing foundation.

If anchoring is required, anchor the unit to the slab using hold down bolts or isolators. Isolators should be installed to minimize the transmission of vibrations into the building.

For rooftop applications, ensure the roof is strong enough to support the combined unit and support structural weight.

If anchoring is required, anchor the unit to the roof with hold-down bolts or isolators.

Check with a roofing contractor for proper waterproofing procedures.

Ductwork

Elbows with turning vanes or splitters are recommended to minimize air noise due to turbulence and to reduce static pressure.

When attaching the ductwork to the unit, provide a water- tight flexible connector at the unit to prevent operating sounds from transmitting through the ductwork.

All outdoor ductwork between the unit and the structure should be weather proofed after installation is completed.

NNoottee:: For sound consideration, cut only the holes in the

roof deck for the ductwork penetrations. Do not cut out the entire roof deck within the curb perimeter.

Roof Curb

The roof curbs for these units consists of a "full perimeter" enclosure to support the unit just inside of the unit base rail.

Before installing any roof curb, verify:

• It is the correct curb for the unit.

• The necessary gaskets and hardware are included.

• The purposed installation location provides the required clearance for proper operation.

• Ensure that the curb is level and square. The top surface of the curb must be true to assure an adequate curb-to-unit seal.

Step-by-step curb assembly and installation instructions ship with each accessory roof curb kit. Follow the instructions carefully to ensure proper fit-up when the unit is set into place.

NNoottee:: To ensure proper condensate flow during

operation, as well as proper operation of the condensate overflow switch (if equipped), the unit and curb must be level.

If the unit is elevated, a field constructed catwalk around the unit is strongly recommended to provide easy access for unit maintenance and service.

Recommendations for installing the Supply Air and Return Air ductwork joining the roof curb are included in the curb instruction booklet. Curb ductwork must be fabricated and installed by the installing contractor before the unit is set into place.

NNoottee:: For sound consideration, cut only the holes in the

roof deck for the ductwork penetrations. Do not cut out the entire roof deck within the curb perimeter.

If a Curb Accessory Kit is Not Used:

• The ductwork can be attached directly to the factory-provided flanges around the unit’s supply

WSHP-SVX015C-EN

Page 35

IInnssttaallllaattiioonn

and return air openings. Be sure to use flexible duct connections at the unit.

• For “built-up” curbs supplied by others, gaskets must be installed around the curb perimeter flange and the supply and return air opening flanges.

General Unit Requirements

The checklist listed below is a summary of the steps required to successfully install a commercial unit. This checklist is intended to acquaint the installing personnel with what is required in the installation process. It does not replace the detailed instructions called out in the applicable sections of this manual.

• Check the unit for shipping damage and material shortage; file a freight claim and notify appropriate sales representative.

• Verify correct model, options and voltage from nameplate.

• Verify that the installation location of the unit will provide the required clearance for proper operation.

• Assemble and install the roof curb (if applicable). Refer to the latest edition of the curb installers guide that ships with each curb kit.

• Fabricate and install ductwork; secure ductwork to curb.

• Rig the unit.

• Set the unit onto the curb; check for levelness.

• Ensure unit-to-curb seal is tight and without buckles or cracks.

• Install and connect a condensate drain line to the evaporator drain connection.

NNoottee:: Condensate Overflow Switch (if equipped) will

not work if unit is not level or slightly sloped toward switch.

Factory Installed Economizer

• Ensure the standard economizer has been pulled out into the operating position. Refer to the economizer Installation Instructions for proper setup.

NNoottee:: Low leak economizers do not pull out. Refer

to low leak economizers installation instructions for proper setup.

• Install all access panels.

Electric Heat Requirements

• Verify that the power supply complies with the electric heater specifications on the unit and heater nameplate.

• Inspect the heater junction box and control panel; tighten any loose connections.

• Check electric heat circuits for continuity.

Temperature Limit Switch Usage for Electric Heat Units

NNoottee:: Applies only to 3 to 10 ton units.

Units are factory shipped in the downflow discharge configuration but can be field converted to a horizontal discharge configuration. Some, but not all units require a different TCO-A limit switch, which is wire tied near the terminal block in the heater compartment if horizontal discharge configuration is used.

Condensate Drain Configuration

An evaporator condensate drain connection is provided on each unit. Refer to the Unit Dimensions section for the appropriate drain location.

A condensate trap must be installed at the unit due to the drain connection being on the “negative pressure” side of the fan. Install the p-trap using the guidelines in

Figure 35, p. 36.

A condensate drain line must be connected to the PTrap. Pitch the drain lines at least 1/2 inch for every 10 feet of horizontal run to assure proper condensate flow. Do not allow the horizontal run to sag causing a possible double-trap condition which could result in condensate backup due to “air lock”.

Measure each leg (phase-to-phase) of the power supply. Each reading must fall within the utilization range stamped on the unit nameplate. If any of the readings do not fall within the proper tolerances, notify the power company to correct this situation before operating the unit.

Excessive three phase voltage imbalance between phases will cause motors to overheat and eventually fail. The maximum allowable voltage imbalance is 2%. Measure and record the voltage between phases 1, 2, and 3 and calculate the amount of imbalance as follows:

% Voltage Imbalance =

where Average Voltage (AV);

V1, V2, V3 = Line Voltage Readings

VD = Line Voltage reading that deviates the farthest from the average voltage.

Example: If the voltage readings of the supply power measured 221, 230, and 227, the average volts would be:

VD (reading farthest from average) = 221

The percentage of Imbalance equals:

• Turn the field supplied disconnect switch that provides power to the main power terminal block or to the “Line” side of the optional factory mounted disconnect switch to the “Off” position.

• Connect the phase sequence indicator leads to the terminal block or to the “Line” side of the optional factory mounted disconnect switch as follows;

– Black (phase A) to L1

– Red (phase B) to L2

– Yellow (phase C) to L3

• Close the field supplied main power disconnect switch or circuit protector switch that provides the supply power to the unit.

• Observe the ABC and CBA phase indicator lights on the face of the sequencer. The ABC indicator light will glow if the phase is ABC. If the CBA indicator light glows, open the disconnect switch or circuit protection switch and reverse any two power wires.

• Restore the main electrical power and recheck the phasing. If the phasing is correct, open the disconnect switch or circuit protection switch and remove the phase sequence indicator.

The 2.2% imbalance in this example exceeds the maximum allowable imbalance of 2.0%. This much imbalance between phases can equal as much as a 20% current imbalance with a resulting increase in motor winding temperatures that will decrease motor life. If the voltage imbalance is over 2%, notify the proper agencies to correct the voltage problem before operating this equipment.

Electrical Phasing (Three Phase Motors)

The compressor motor(s) and the supply fan motor are internally connected for the proper rotation when the incoming power supply is phased as A, B, C.

Proper electrical supply phasing can be quickly determined and corrected before starting the unit by using an instrument such as an Associated Research Model 45 Phase Sequence Indicator and following the steps below:

WSHP-SVX015C-EN

Each compressor is equipped with a crankcase heater. The proper operation of the crankcase heater is important to maintain an elevated compressor oil temperature during the “Off” cycle to reduce oil foaming during compressor starts. Oil foaming occurs when refrigerant condenses in the compressor and mixes with the oil. In lower ambient conditions, refrigerant migration to the compressor could increase.

When the compressor starts, the sudden reduction in crankcase pressure causes the liquid refrigerant to boil rapidly causing the oil to foam. This condition could damage compressor bearings due to reduced lubrication and could cause compressor mechanical failures.

Before starting the unit in the “Cooling” mode, set the system switch to the “Off” position and turn the main power disconnect to the “On” position and allow the crankcase heater to operate a minimum of 8 hours.

Before closing the main power disconnect switch, insure that the “System” selection switch is in the “Off” position and the “Fan” selection switch is in the “Auto” position.

Page 46

IInnssttaallllaattiioonn

Close the main power disconnect switch and the unit mounted disconnect switch, if applicable.

ReliaTel™™ Controls

Upon power initialization, the RTRM performs selfdiagnostic checks to insure that all internal controls are functional. It also checks the configuration parameters against the components connected to the system. The Liteport LED located on the RTRM module is turned “On” within one second of power-up if internal operation is okay.

Use one of the following “Test” procedure to bypass some time delays and to start the unit at the control panel. Each step of unit operation can be activated individually by temporarily shorting across the “Test” terminals for two to three seconds. The Liteport LED located on the RTRM module will blink when the test mode has been initiated. The unit can be left in any “Test” step for up to one hour before it will automatically terminate, or it can be terminated by opening the main power disconnect switch. Once the test mode has been terminated, the Liteport LED will glow continuously and the unit will revert to the “System” control.

Final Steps

Use the checklist provided below in conjunction with the checklist in General Unit Requirements, to ensure that the unit is properly installed and ready for operation.

• Check all electrical connections for tightness and “point of termination” accuracy.

• Verify that the indoor blower turn freely without rubbing and are properly tightened on the shafts.

• Check the supply fan belts for proper tension and the fan bearings for sufficient lubrication. If the belts require adjustment, or if the bearings need lubricating, refer to the maintenance section of this manual for instructions.

• Verify that a condensate trap is installed and the piping is properly sized and pitched.

• Verify that the correct size and number of filters are in place.

• Inspect the interior of the unit for tools and debris and install all panels in preparation for starting the unit.

Prerequisite

NNoottee:: The following field installation instructions apply

to downflow only. Horizontal return air smoke detectors require no field installation.

When a unit is ordered with a downflow economizer and a return air smoke detector as factory installed options, the return air smoke detector cannot be completely installed because the economizer, when it is in the shipping position, is occupying the space where the return air smoke detector is to be installed.

The partial assembly and set-up required for each factory installed economizer must be completed up to the point where the barometric relief hood is to be installed into the unit. Prior to this operation, go to Step 5 of this instruction and perform the operations described there. After this is completed, the economizer installation is to be completed in its entirety as outlined in the installation guide.

Smoke Detector Installation

IImmppoorrttaanntt:: The shipping screw that holds the

barometric relief damper must be removed before proceeding with the smoke detector installation.

After completion of the economizer installation as outlined above, proceed with the installation of the return air smoke detector as follows:

4. Slide one 2” piece of the vinyl tubing provided onto the short smoke detector inlet tube which protrudes out of the back side of the smoke detector. Push this piece of vinyl tubing onto the inlet tube until it contacts the end of the plastic extension on the backside of the smoke detector.

5. Slide the long piece of vinyl tubing provided onto one leg of the plastic barbed elbow provided. Slide the other end of this piece of vinyl tubing with the elbow attached approximately 1” onto the end of the copper sampling tube installed in the unit’s return air opening. Position the leg of elbow without the vinyl tubing such that it points toward the front side of the unit (directly out of the unit toward the filter access panel).

6. Mount the smoke detector assembly into the unit. Align the smoke detector (exhaust tube down) with the holes in the outer panel of the barometric relief hood and position the smoke detector flush on the panel.

NNoottee:: On all units there is a hole with a plastic snap

bushing located on the inner vertical side of the barometric relief hood that the long exhaust tube must pass through. Be sure that the exhaust tube is aligned with this hole before positioning the smoke detector flush on the outer panel of the barometric relief hood.

7. Secure the smoke detector to the hood with two #10-16 x 3/4’ sheet metal screws provided.

NNoottee:: In order to perform the last part of this operation,

it will be necessary to remove the barometric relief filter, open the barometric relief damper, and reach inside through the barometric relief outlet to access and connect the copper exhaust elbow to the smoke detector exhaust tube.

8. Connect the leg of the plastic elbow without the vinyl tubing attached that was installed in Step 5 to the smoke detector inlet tube pushing it onto the piece of vinyl tubing attached to the inlet tube.

9. Refer to “Return Air Smoke Detector 12.5 to 20

Tons,” p. 50 for wire connections of return air

smoke detector to the unit wiring harness.

10. This completes the installation of the return air smoke detector. If the unit’s air filter(s) and/or barometric relief filter were removed to ease installation of the smoke detector, they need to be replaced at this time.

IImmppoorrttaanntt:: The return air smoke detector is designed

to shut off the unit if smoke is sensed in the return air stream. This function is performed by sampling the airflow entering the unit at the return air opening. Follow the instructions provided below to assure that the airflow through the unit is sufficient for adequate sampling. Failure to follow these instructions will prevent the smoke detector from performing its design function.

In order for the return air smoke detector to properly sense smoke in the return air stream, the air velocity entering the unit must be between 500 and 4000 feet per minute.

NNootteess::

• Airflow through the unit is affected by the amount of dirt and debris accumulated on the indoor coil and filters. To insure that airflow through the unit is adequate for proper sampling by the return air smoke detector, complete adherence to the maintenance procedures, including recommended intervals between filter changes and coil cleaning, is required.

• Periodic checks and maintenance procedures must be performed on the smoke detector to insure that it will function properly. For detailed instructions concerning these checks and procedures, refer to the appropriate section(s) of the smoke detector Installation and Maintenance Instructions provided with the literature package for this unit.

IImmppoorrttaanntt:: Refer to the service literature provided for

testing and other information about the smoke detector or if problems are encountered.

Pre-Start

Test Modes

There are three methods in which the “Test” mode can be cycled at LTB-Test 1 and LTB-Test 2.

1. Step Test Mode - This method initiates the different components of the unit, one at a time, by temporarily shorting across the two test terminals for two to three seconds.

For the initial start-up of the unit, this method allows the technician to cycle a component “On” and have up to one hour to complete the check.

2. Resistance Test Mode - This method can be used for start-up providing a decade box for variable resistance outputs is available. This method initiates the different components of the unit, one at a time, when a specific resistance value is placed

across the two test terminals. The unit will remain in the specific test mode for approximately one hour even though the resistance is left on the test terminals.

3. Auto Test Mode - This method is not recommended for start-up due to the short timing between individual component steps. This method initiates the different components of the unit, one at a time, when a jumper is installed across the test terminals. The unit will start the first test step and change to the next step every 30 seconds. At the end of the test mode, control of the unit will automatically revert to the applied “System” control method.

For unit test steps, test modes, and step resistance values to cycle the various components, refer to the service test guide for component operation table.

Sequence of Operation

ReliaTel™™ Controls

Units are offered with the ReliaTel™ control.

ReliaTel™ control is a microelectronic control feature, which provides operating functions that are significantly different than conventional electromechanical units. The master module is the ReliaTel™ refrigeration module (RTRM).

The RTRM provides compressor anti-short cycle timing functions through minimum “Off” and “On” timing to increase reliability, performance and to maximize unit efficiency.

Upon power initialization, the RTRM performs selfdiagnostic checks to insure that all internal controls are functioning. It checks the configuration parameters

WSHP-SVX015C-EN

against the components connected to the system. The LED located on the RTRM module is turned “On” within one second after power-up if all internal operations are okay.

ReliaTel™™ Control Cooling without an Economizer

When the system switch is set to the “Cool” position and the zone temperature rises above the cooling setpoint control band, the RTRM energizes the (K9) relay coil located on the RTRM. When the K9 relay contacts close, the compressor contactor (CC1) coil is energized provided the low pressure control (LPC1), high pressure control (HPC1) and discharge line thermostat (TDL 1) are closed. When the CC1 contacts close, compressor (CPR1) start to maintain the zone

Page 56

PPrree--SSttaarrtt

temperature to within ± 2ºF of the sensor setpoint at the sensed location.

If the first stage of cooling cannot satisfy the cooling requirement, the RTRM energizes the (K10) relay coil located on the RTRM. When the (K10) relay contacts close, the compressor contactor (CC2) coil is energized provided the low pressure control (LPC2), high pressure control (HPC2) and discharge line thermostat (TDL 2) are closed. When the CC2 contacts close, compressor (CPR2) starts to maintain the zone temperature to within ± 2ºF of the sensor setpoint at the sensed location.

Much of the systems performance and reliability is closely associated with, and dependent upon having the proper airflow supplied both to the space that is being conditioned and across the evaporator coil.

The indoor fan motor is factory wired to operate on speed tap 1 in the cooling and heating mode for electric/electric units. For electric, heat pump units, the

WSHP-SVX015C-EN

PPrree--SSttaarrtt

motor is factory wired to operate on speed tap 1 during cooling. For 3 & 4 ton electric units operating in heat mode, the minimum setting is Tap 4.

For these units, a separate tap terminal is provided to change speeds automatically between heating and cooling. The motor can be rewired for different speed settings should the application require it. Refer to the wiring diagram that shipped in the unit and the unit fan performance tables in the Service Facts.

The indoor fan motors are specifically designed to operate within the BHP parameters listed in the fan performance tables of the unit service facts.

When verifying direct drive fan performance, the tables must be used somewhat differently than those of belt driven fans. Fan performance diagnostics can be easily recognized when these tables are used correctly.

Before starting the SERVICE TEST, set the minimum position setpoint for the economizer to 0% using the setpoint potentiometer located on the Economizer Control (ECA), if applicable.

Once the supply fan has started, check for proper rotation. The direction of rotation is indicated by an arrow on the fan housing.

With the fan operating properly, determine the total system airflow (CFM) by;

1. Measuring the actual RPM,

2. Measure the amperage at the supply fan contactor and compare it with the full load amp (FLA) rating stamped on the motor nameplate.

a. Calculate the theoretical BHP

Actual Motor Amps X Motor HP

Motor Nameplate Amps

b. Using the fan performance tables in the unit

Service Facts, plot the actual RPM (step 1) and the BHP (step 2a) to obtain the operating CFM.

3. If the required CFM is too low, (external static pressure is high causing motor HP output to be below table value),

a. Relieve supply and/or return duct static.

b. Change indoor fan speed and repeat steps 1 and

• To Increase Fan RPM; Loosen the pulley adjustment set screw and turn sheave clockwise.

• To Decrease Fan RPM; Loosen the pulley adjustment set screw and turn sheave counterclockwise.

• If the required CFM is too high, (external static pressure is low causing motor HP output to be above table value), change indoor fan speed and repeat steps 1 and 2.

• To stop the SERVICE TEST, turn the main power disconnect switch to the “Off” position or proceed to the next component start-up procedure. Remove electro mechanical test mode connections (if applicable).

Return Air Smoke Detector

The return air smoke detector is designed to shut off the unit if smoke is sensed in the return air stream. Sampling the airflow entering the unit at the return air opening performs this function.

In order for the smoke detector to properly sense smoke in the return air stream, the air velocity entering the unit must be between 500 and 4000 feet per minute. Equipment covered in this manual will develop an airflow velocity that falls within these limits over the entire airflow range specified in the evaporator fan performance tables.

Start Up

Economizer Start-Up

Using the service test guide for component operation table, momentarily jump across the Test 1 & Test 2 terminals on LTB1 one time to start the Minimum Ventilation Test.

1. Set the minimum position setpoint for the economizer to the required percentage of minimum ventilation using the setpoint potentiometer located on the Economizer Control Actuator (ECA).

The economizer will drive to its minimum position setpoint, exhaust fans (if applicable) may start at random, and the supply fan will start when the SERVICE TEST is initiated.

The Exhaust Fan will start anytime the economizer damper position is equal to or greater than the exhaust fan setpoint.

2. Verify that the dampers stroked to the minimum position.

3. Momentarily jump across the Test 1 & Test 2 terminals on LTB one additional time if continuing from previous component start-up or until the desired start-up component Test is started.

4. Verify that the dampers stroked to the full open position.

5. To stop the SERVICE TEST, turn the main power disconnect switch to the “Off” position or proceed to the next component start-up procedure. Remove electro mechanical test mode connections (if applicable).

Compressor Start-Up

1. Attach a set of service gauges onto the suction and discharge gauge ports for each circuit. Refer to the refrigerant circuit illustration in the Service Facts.

Using the Service test guide for component operation table, continue the Service Test start-up procedure for each compressor circuit.

Momentarily jump across the Test 1 & Test 2 terminals on LTB1 one additional time if continuing from previous component start-up or until the desired start-up component Test is started.

a. Once each compressor has started, verify that

the rotation is correct. To check rotation, use a set of refrigeration gauges hooked up to the suction and discharge pressure port. If the compressor is phased correctly the suction pressure should drop and the discharge pressure should rise when the compressor starts and runs. If a scroll compressor is rotating backwards, it will not pump, the suction and discharge pressure will not rise, and a loud

rattling sound can be observed.

b. If the electrical phasing is incorrect, before

condemning a compressor, interchange any two leads (at the compressor terminal block) to check the internal phasing. Refer to the following illustration for the compressor terminal/phase identification. If the compressor runs backward for an extended period not to exceed 5 seconds, the compressor will be damaged the motor winding can overheat and cause the motor winding thermostat to open and the oil can turn dark gray.

c. Check the compressor oil levels. The oil level in

each compressor sight glass should be visible in the compressor sightglass. This only applies to CSHD compressors, SSA and SPA compressors don't have sight glasses.

NNoottee:: SSA and SPA scroll compressors for R-410A

units use Trane OIL00094. The correct oil for Trane CSHD is Trane OIL00079 or OIL00080. Compressor types are listed in the table below. The appropriate oil charge is also listed below

2. After the compressor starts and operates for approximately 30 minutes, observe the operating pressures. Compare the operating pressures to the operating pressure curve.

3. Check system superheat. Follow the instruction listed on the superheat charging curve. Superheat should be within ±5ºF of the superheat chart value.

4. Repeat steps 1 through 4 for each refrigerant circuit.

5. To stop the Service Test, turn the main power disconnect switch to the “Off” position or proceed to the next component start-up procedure.

SSA and SPA scroll compressors for R-410A units use Trane OIL00094. The correct Oil for Trane CSHD is Trane OIL00079 or OIL00080. Compressor types are listed in the following table. The appropriate oil charge is also listed below.

Make sure all personnel are standing clear of the unit before proceeding. The system components will start when the power is applied.

Fan Belt Adjustment

The supply fan belts must be inspected periodically to assure proper unit operation.

Replacement is necessary if the belts appear frayed or worn. Units with dual belts require a matched set of belts to ensure equal belt length. When installing new belts, do not stretch them over the sheaves; instead, loosen the adjustable motor-mounting base.

Once the new belts are installed, adjust the belt tension using a Browning or Gates tension gauge (or equivalent) illustrated in Figure 63, p. 65.

WWAARRNNIINNGG

1. To determine the appropriate belt deflection:

a. Measure the center-to-center distance, in

inches, between the fan sheave and the motor sheave.

b. Divide the distance measured in Step 1a by 64;

the resulting value represents the amount of belt deflection for the proper belt tension.

2. Set the large O-ring on the belt tension gauge at the deflection value determined in Step 1b.

3. Set the small O-ring at zero on the force scale of the gauge.

4. Place the large end of the gauge on the belt at the center of the belt span. Depress the gauge plunger until the large O-ring is even with the of the second belt or even with a straightedge placed across the sheaves.

5. Remove the tension gauge from the belt. Notice that the small O-ring now indicates a value other than zero on the force scale. This value represents the force (in pounds) required to deflect the belt(s) the proper distance when properly adjusted.

6. Compare the force scale reading in step 5 with the appropriate “force” value in Table 21, p. 66. If the force reading is outside of the listed range for the type of belts used, either readjust the belt tension or contact a qualified service representative.

NNoottee:: The actual belt deflection force must not

exceed the maximum value shown in Table

21, p. 66.

7. Recheck the new belt's tension at least twice during the first 2 to 3 days of operation. Readjust the belt tension as necessary to correct for any stretching that may have occurred. Until the new belts are “run in”, the belt tension will decrease rapidly as they stretch.

Cooling Season

• Check the unit’s drain pans and condensate piping to ensure that there are no blockages.

• Inspect the evaporator for dirt, bent fins, etc. If the coil appears dirty, clean it according to the instructions described in “Coil Cleaning” later in this section.

• Inspect the F/A-R/A damper hinges and pins to ensure that all moving parts are securely mounted. Keep the blades clean as necessary.

• Verify that all damper linkages move freely; lubricate with white grease, if necessary.

• Check supply fan motor bearings; repair or replace the motor as necessary.

• Check the fan shaft bearings for wear. Replace the bearings as necessary.

• Check the supply fan belt. If the belt is frayed or worn, replace it. Refer to the “Fan Belt Adjustment” section for belt replacement and adjustments.

• Verify that all wire terminal connections are tight.

• Remove any corrosion present on the exterior surfaces of the unit and repaint these areas.

• Generally inspect the unit for unusual conditions (e. g., loose access panels, leaking piping connections, etc.)

• Make sure that all retaining screws are reinstalled in the unit access panels once these checks are complete.

• With the unit running, check and record the: ambient temperature; compressor suction and discharge pressures (each circuit); superheat (each circuit);

Record this data on an “operator’s maintenance log” like the one shown in the sample maintenance log. If the operating pressures indicate a refrigerant shortage, measure the system superheat. For guidelines, refer to the “Compressor Start-Up” section.

NNoottee:: Do not release refrigerant to the atmosphere! If

adding or removing refrigerant is required, the service technician must comply with all federal, state and local laws.

Heating Season

• Inspect the unit’s air filters. If necessary, clean or replace them.

• Check supply fan motor bearings; repair or replace the motor as necessary.

• Inspect both the main unit control panel and heat section control box for loose electrical components and terminal connections, as well as damaged wire insulation. Make any necessary repairs.

• Verify that the electric heat system operates properly.

Coil Cleaning

Regular coil maintenance, including annual cleaning enhances the unit’s operating efficiency by minimizing the following:

• Compressor head pressure and amperage draw

• Water carryover

• Fan brake horsepower

• Static pressure losses

At least once each year—or more often if the unit is located in a “dirty” environment—clean the evaporator coils using the instructions outlined below. Be sure to follow these instructions as closely as possible to avoid damaging the coils.

Refrigerant Coils

To clean refrigerant coils, use a soft brush and a sprayer.

For evaporator coil cleaners, contact the local Trane Parts Center for appropriate detergents.

1. Remove enough panels from the unit to gain safe access to coils.

2. Straighten any bent coil fins with a fin comb.

3. For accessible areas, remove loose dirt and debris from both sides of the coil.

4. When cleaning evaporator coils, mix the detergent with water according to the manufacturer’s instructions. If desired, heat the solution to 150° F maximum to improve its cleansing capability.

IImmppoorrttaanntt:: DO NOT use any detergents with

microchannel coils. Pressurized water or air ONLY.

5. Pour the cleaning solution into the sprayer. If a high-pressure sprayer is used:

a. The minimum nozzle spray angle is 15 degrees.

b. Do not allow sprayer pressure to exceed 600 psi.

c. Spray the solution perpendicular (at 90 degrees)

to the coil face.

d. For evaporator coils, maintain a minimum

clearance of 6" between the sprayer nozzle and the coil. For microchannel coils, optimum clearance between the sprayer nozzle and the microchannel coil is 1"-3”.

6. Spray the leaving-airflow side of the coil first; then spray the opposite side of the coil. For evaporatorcoils, allow the cleaning solution to stand on the coil for five minutes.

7. Rinse both sides of the coil with cool, clean water.

8. Inspect both sides of the coil; if it still appears to be dirty, repeat Steps 6 and 7.

9. Reinstall all of the components and panels removed in Step 1; then restore power to the unit.

10. For evaporator coils, use a fin comb to straighten any coil fins which were inadvertently bent during the cleaning process.

ReliaTel™™ Controls

The RTRM has the ability to provide the service personnel with some unit diagnostics and system status information.

Before turning the main power disconnect switch “Off”, follow the steps below to check the ReliaTel™ Refrigeration Module (RTRM). All diagnostics & system status information stored in the RTRM will be lost when the main power is turned “Off”.

To prevent injury or death from electrocution, it is the responsibility of the technician to recognize this hazard and use extreme care when performing service procedures with the electrical power energized.

1. Verify that the Liteport LED on the RTRM is burning continuously. If the LED is lit, go to Step 3.

2. If the LED is not lit, verify that 24 VAC is presence between J1-1 and J1-2. If 24 Vac is present, proceed to Step 3. If 24 Vac is not present, check the unit main power supply, check transformer (TNS1). Proceed to Step 3 if necessary.

3. Utilizing “Method 1” or “Method 2” in the “System Status Checkout Procedure ” section, check the following:

System status

Heating status

Cooling status

If a System failure is indicated, proceed to Step 4. If no failures are indicated, proceed to Step 5.

4. If a System failure is indicated, recheck Steps 1 and

2. If the LED is not lit in Step 1, and 24 VAC is

present in Step 2, the RTRM has failed. Replace the RTRM.

5. If no failures are indicated, use one of the TEST mode procedures described in the “Unit Start-Up” section to start the unit. This procedure will allow you to check all of the RTRM outputs, and all of the external controls (relays, contactors, etc.) that the RTRM outputs energize, for each respective mode. Proceed to Step 6.

6. Step the system through all of the available modes, and verify operation of all outputs, controls, and modes. If a problem in operation is noted in any mode, you may leave the system in that mode for up to one hour while troubleshooting. Refer to the sequence of operations for each mode, to assist in verifying proper operation. Make the necessary repairs and proceed to Steps 7 and 8.

7. If no abnormal operating conditions appear in the test mode, exit the test mode by turning the power “Off” at the main power disconnect switch.

8. Refer to the individual component test procedures if other microelectronic components are suspect.

System Status Checkout Procedure

“System Status” is checked by using one of the following two methods:

Method 1

If the Zone Sensor Module (ZSM) is equipped with a remote panel with LED status indication, you can check the unit within the space. If the ZSM does not have LED’s, use Method 2. BAYSENS110*, and BAYSENS119* all have the remote panel indication feature. The LED descriptions are listed below.

LED 1 (System)

“On” during normal operation.

“Off” if a system failure occurs or the LED fails.

Failure indication causes

System Failure

Check the voltage between terminals 6 and 9 on J6, it should read approximately 32 Vdc. If no voltage is present, a System failure has occurred. Refer to Step 4 in the previous section for the recommended troubleshooting procedure.

Cooling Failure

1. Cooling and heating set point (slide pot) on the zone sensor has failed. Refer to the “Zone Sensor Test Procedure” section.

2. Zone temperature thermistor ZTEMP on ZTS failed. Refer to the “Zone Sensor Test Procedure” section.

3. CC1 or CC2 24 Vac control circuit has opened, check CC1 & CC2 coils, and any of the controls below that apply to the unit (HPC1, HPC2).

4. LPC1 has opened during the 3 minute minimum “on time” during 4 consecutive compressor starts, check LPC1 or LPC2 by testing voltage between the J1-8 & J3-2 terminals on the RTRM and ground. If 24 VAC is present, the LPC’s has not tripped. If no voltage is present, LPC’s has tripped.

Service Failure

1. If the supply fan proving switch has closed, the unit will not operate (when connected to RTOM), check the fan motor, belts, and proving switch.

2. Clogged filter switch has closed, check the filters.

Heat Failure

Measure the voltage between terminals J6-7 & J6-6.

Heat Operating = approximately 32 Vdc

Heat Off = less than 1 VDC, approximately 0.75 Vdc

Heating Failure = voltage alternates between 32 Vdc &

0.75 Vdc

Cool Failure

Measure the voltage between terminals J6-8 & J6-6.

Cool Operating = approximately 32 Vdc

Cool Off = less than 1 Vdc, approximately 0.75 Vdc

Cooling Failure = voltage alternates between 32 Vdc &

0.75 Vdc

Service Failure

Measure the voltage between terminals J6-10 & J6-6.

Clogged Filter = Approximately 32 Vdc.

Normal = Less than 1 Vdc, approximately 0.75 Vdc

Fan Failure = voltage alternates between 32 Vdc & 0.75 Vdc.

NNoottee:: If the Condensate Overflow Switch is closed, the

unit will not operate. Check to make sure the float position is not in a tripped condition and verify an "open" between wires connecting to RTOM J6-1, J6-2.

To use LED’s for quick status information at the unit, purchase a BAYSENS110* ZSM and connect wires with alligator clamps to terminals 6 through 10. Connect each respective terminal wire (6 through 10) from the Zone Sensor to the unit J6 terminals 6 through 10.

NNoottee:: If the system is equipped with a programmable

zone sensor, (BAYSENS119*), the LED indicators will not function while the BAYSENS110* is connected.

Simultaneous Heat and Cool Failure

1. Emergency Stop is activated.

Method 2

The second method for determining system status is done by checking voltage readings at the RTRM (J6). The system indication descriptions and the approximate voltages are listed below.

System Failure

Measure the voltage between terminals J6-9 & J6-6.

Normal Operation = approximately 32 Vdc

System Failure = less than 1 Vdc, approximately 0.75 Vdc

Test Mode = voltage alternates between 32 Vdc & 0.75 Vdc

Resetting Cooling and Heating Lockouts

Cooling Failures and Heating Lockouts are reset in an identical manner. Method 1 explains resetting the system from the space; Method 2 explains resetting the system at the unit.

NNoottee:: Before resetting Cooling Failures and Heating

Lockouts check the Failure Status Diagnostics by the methods previously explained. Diagnostics will be lost when the power to the unit is disconnected.

Method 1

To reset the system from the space, turn the “Mode” selection switch at the zone sensor to the “Off” position. After approximately 30 seconds, turn the “Mode” selection switch to the desired mode, i.e. Heat, Cool or Auto.

WSHP-SVX015C-EN

TTrroouubblleesshhoooottiinngg

Method 2

To reset the system at the unit, cycle the unit power by turning the disconnect switch “Off” and then “On”.

Lockouts can be cleared through the building management system. Refer to the building management system instructions for more information.

Zone Temperature Sensor (ZTS) Service Indicator

The ZSM SERVICE LED is a generic indicator, that will signal the closing of a Normally Open switch at any time, providing the Indoor Motor (IDM) is operating. This indicator is usually used to indicate a clogged filter, or an air side fan failure.

The RTRM will ignore the closing of this Normally Open switch for 2 (±1) minutes. This helps prevent nuisance SERVICE LED indications. The exception is the LED will flash 40 seconds after the fan is turned “On” if the Fan Proving Switch is not made.

Clogged Filter Switch

This LED will remain lit the entire time that the Normally Open switch is closed. The LED will be turned off immediately after resetting the switch (to the Normally Open position), or any time that the IDM is turned “Off”.

If the switch remains closed, and the IDM is turned “On”, the SERVICE LED will be turned “On” again after the 2 (±1) minute ignore delay.

This LED being turned “On”, will have no other affect on unit operation. It is an indicator only.

Fan Failure Switch

When the “Fan Failure” switch is wired to the RTOM, the LED will remain flashing the entire time the fan proving switch is closed, indicating a fan failure, and it will shut the unit operations down.

Condensate Overflow Switch

This input incorporates the condensate overflow switch (COF) mounted on the drain pan and the ReliaTel™ options module (RTOM). When the condensate level reaches the trip point for 6 continuous seconds, the RTOM will shut down all unit function until the overflow condition has cleared. The unit will return to normal operation after 6 continuous seconds with the COF in a non-tripped condition. If the condensate level causes the unit to shut down more than 2 times in a 3 day period, the unit will be locked-out of operation. A manual reset of the diagnostic system through the zone sensor or Building Automation System (BAS) will be required. Cycling unit power will also clear the fault.

Zone Temperature Sensor (ZTS) Tests

NNoottee:: These procedures are not for programmable or

digital models and are conducted with the Zone Sensor Module electrically removed from the system.

Test 1: Zone Temperature Thermistor (ZTEMP)

This component is tested by measuring the resistance between terminals 1 and 2 on the Zone Temperature Sensor. Below are some typical indoor temperatures, and corresponding resistive values.

Zone Temperature

50 F° 10.0 C° 19.9 K-Ohms 889 Ohms

55 F° 12.8 C° 17.47 K-Ohms 812 Ohms

60 F° 15.6 C° 15.3 K-Ohms 695 Ohms

65 F° 18.3 C° 13.49 K-Ohms 597 Ohms

70 F° 21.1 C° 11.9 K-Ohms 500 Ohms

Resistance

Test 2: Cooling Set Point (CSP) and Heating Set Point (HSP)

The resistance of these potentiometers are measured between the following ZSM terminals. Refer to the chart above for approximate resistances at the given setpoints.

Cool SP = Terminals 2 and 3

Range = 100 to 900 Ohms approximate

Heat SP = Terminals 2 and 5

Range = 100 to 900 Ohms approximate

Test 3: System Mode and Fan Selection

The combined resistance of the Mode selection switch and the Fan selection switch can be measured between terminals 2 and 4 on the Zone Sensor. The possible switch combinations are listed on the following page with their corresponding resistance values.

Test 4: LED Indicator Test, (SYS ON, HEAT, COOL & SERVICE)

Method 1

Testing the LED using a meter with diode test function. Test both forward and reverse bias. Forward bias

should measure a voltage drop of 1.5 to 2.5 volts, depending on your meter. Reverse bias will show an over Load, or open circuit indication if LED is functional.

Method 2

Testing the LED with an analog Ohmmeter. Connect Ohmmeter across LED in one direction, then reverse the leads for the opposite direction. The LED should have at least 100 times more resistance in reverse direction, as compared with the forward direction. If high resistance in both directions, LED is open. If low in both directions, LED is shorted.

Method 3

To test LED’s with ZSM connected to unit, test voltages at LED terminals on ZSM. A measurement of 32 VDC, across an unlit LED, means the LED has failed.

NNoottee:: Measurements should be made from LED

common (ZSM terminal 6 to respective LED terminal). Refer to the Zone Sensor Module (ZSM) Terminal Identification table at the beginning of this section.
