Cautions are designed to alert personnel to hazardous situations that could result in personal injury, while notices indicate a situation that could result in equipment or property-damage-only accidents.

Your personal safety and the proper operation of this

machine depend upon the strict observance of these precautions.

Read this manual thoroughly before operating or servicing this unit.

ATTENTION: Warnings, Cautions and Notices appear at

appropriate sections throughout this literature. Read these carefully:

WARNING

CAUTIONs

NOTICE:

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 situationthat could result in equipment or property-damage only

must also be adhered to for responsible management of refrigerants. Know the applicable laws and follow them.

WARNING

Proper Field Wiring and Grounding Required!

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. Failure to follow code could result in death or serious injury.

WARNING

R-410A Refrigerant under Higher Pressure than R-22!

The units described in this manual use R-410A

refrigerant which operates at higher pressures than R22 refrigerant. Use ONLY R-410A rated service equipment or components with these units. For specific handling concerns with R-410A, please contact your localTrane representative. Failure to use R-410A rated service equipment or components could result in equipment exploding under R-410A high pressures which could result in death, serious injury, or equipment damage.

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.

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.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

WARNING

General Information

Unit Description

The CGAM units are scroll type, air-cooled, liquid chillers,

designed for installation outdoors.The 20-35 ton units have a single independent refrigerant circuit, with two compressors per circuit.The 40 ton and larger units have 2 independent refrigerant circuits, with two compressors per circuit.The CGAM units are packaged with an evaporator and condenser.

Note: Each CGAM unit is a completely assembled,

hermetic -compressors packaged unit that is factory-piped, wired, leak-tested, dehydrated, charged and tested for proper control operations prior to shipment.The chilled water inlet and outlet openings are covered for shipment.

The CGAM series featuresTrane's exclusive Adaptive Control logic with CH530 controls. It monitors the control variables that govern the operation of the chiller unit. Adaptive Control logic can correct these variables, when necessary, to optimize operational efficiencies, avoid chiller shutdown, and keep producing chilled water.

Each refrigerant circuit is provided with filter, sight glass, electronic expansion valve, and charging valves on the CGAM.

The evaporator is a brazed plate heat exchanger which is

equipped with a water drain and vent connections in the water piping.The condenser is an air-cooled slit fin coil.

The condensers are available in three configurations

depending on the tonnage of the unit. Units may be referred to the size by the condenser configuration.The three configurations are slant, V and W.

Pre-Installation

Inspection Checklist

When the unit is delivered, verify that it is the correct unit

and that it is properly equipped. Compare the information which appears on the unit nameplate with the ordering and submittal information.

Inspect all exteriorcomponents for visibledamage. Report any apparent damage or material shortage to the carrier and make a “unit damage” notation on the carrier's delivery receipt. Specify the extent and type of damage found and notify the appropriateTrane Sales Office.

Do not proceedwith installation ofa damaged unitwithout sales office approval.

To protect against loss due to damage incurred in transit,

complete the following checklist upon receipt of the unit.

• Inspect the individual pieces of the shipment before accepting the unit. Check for obvious damage to the unit or packing material.

• Inspect the unit for concealed damage as soon as possible after delivery and before it is stored. Concealed damage must be reported within 15 days.

• If concealed damage is discovered, stop unpacking the shipment. Do not remove damaged material from the receiving location.Take photos of the damage, if possible.The owner must provide reasonable evidence that the damage did not occur after delivery.

• Notify the carrier's terminal of the damage immediately, by phone and by mail. Request an immediate, joint inspection of the damage with the carrier and the consignee.

• Notify theTrane sales representative and arrange for repair. Do not repair the unit, however, until damage is inspected by the carrier's representative.

Unit Storage

If the chiller is to be stored in ambients of 32°F or less, evaporator should be blown out to remove any liquid and refrigerant isolation valves should be closed.

If the chiller is to be stored for more than one month prior to installation, observe the following precautions:

• Do not remove the protective coverings from the electrical panel.

• Store the chiller in a dry, vibration-free, secure area.

• Units charged with refrigerant should not be stored where temperatures exceed 155°F.

• At least every three months, attach a gauge and manually check the pressure in the refrigerant circuit. If the refrigerant pressure is below 200 psig at 70 F (or 145 psig at 50 F), call a qualified service organization and the appropriateTrane sales office.

Note: Pressure will be approximately 20 psig if shipped

with the optional nitrogen charge.

Installation - Mechanical

Location Requirements

Sound Considerations

• Refer toTrane Engineering Bulletin Chiller Sound Ratings and Installation Guide CG-PRB010-EN for

sound consideration applications.

• Locate the unit away from sound-sensitive areas.

• Install the optional elastomeric isolators under the unit. Refer to “Unit Isolation.”

• Chilled water piping should not besupported by chiller frame.

• Install rubber vibration isolators in all water piping.

• Seal all wall penetrations.

Note: Consult an acoustical engineer for critical

applications.

Foundation

Provide rigid, non-warping mounting pads or a concrete foundation of sufficient strength and mass to support the applicable operating weight (i.e., including completed piping, and full operating charges of refrigerant, oil and water). Refer to the chapter on “Unit Dimensions/Weights” for unit operating weights. Once in place, the unit must be level within 1/4” (6.4 mm) over its length and width.The

Trane Company is not responsible for equipment

problems resulting from an improperly designed or constructed foundation.

Clearances

Provide enough space around the unit to allow the installation and maintenance personnel unrestricted access to all servicepoints. Refer to submittal drawings for the unit dimensions, to provide sufficient clearance for the opening of control panel doors and unit service. Refer to the chapter on “Unit Dimensions/Weights” for minimum clearances. In all cases, local codes which require additional clearances will take precedence over these recommendations.

Rigging

Refer to Unit Dimensions/Weights section for typical unit lifting weights. Refer to the rigging label attached to the unit for further details.

Lifting Procedure

WARNING

Heavy Objects!

Ensure that all the lifting equipment used is properly rated for the weight of the unit being lifted. Each of the cables (chains or slings), hooks, and shackles used to lift the unit must be capable of supporting the entire weight of the unit. Lifting cables (chains or slings) may not be of the same length. Adjust as necessary for even unit lift. Other lifting arrangements could cause equipment or property damage. Failure to follow instructions above or properly lift unit could result in unit dropping and possibly crushing operator/ technician which could result in death or serious injury.

WARNING

Improper Unit Lift!

Test lift unit approximately 24 inches to verify proper

center of gravity lift point. To avoid dropping of unit, reposition lifting point if unit is not level. Failure to properly lift unit could result in unit dropping and possibly crushing operator/technician which could result in death or serious injury and possible equipment or property-only damage.

Lifting using either a single spreader bar or an H-type spreader is acceptable. Attach chains or cables to lifting beam. Lifting beam crossbars MUST be positioned so lifting cables do not contact the sides of the unit.

Important: The center of gravity (CG) is never at the

midpoint of the base rail lifting strap holes.

A level unit lift is required for a safe lift and

to prevent unit damage.

Lifting a unit with equal length straps will NOT produce a level unit during the lift because the CG will not be at the midpoint between the base lifting holes.The following adjustments must be made to produce a level lift:

• Single spreader bar lifting method

• If the unit CG is closer to the control panel, the

straps on the control panel side of the spreader bar must be adjusted to be shorter than those on the opposite side of the spreader bar, allowing the spreader bar to move toward the control panel and over the unit CG. Several adjustments of the strap length may be required to produce a level unit during lift.

• H-type spreader bar lifting method

• If the straps from the H bar to the unit base are the

same length, the crane lifting point on the center web of theH bar must beadjusted to producea level unit lift. See Figure 35, p. 33 for illustration.

Unit Isolation and Leveling

Mounting

Construct an isolated concrete pad for the unit or provide concrete footings at each of the four unit mounting points. Mount the unit directly to the concrete pads or footings.

Level the unit using the base rail as a reference.The unit must be level within 1/4” over the entire length. Use shims as necessary to level the unit.

Elastomeric Isolator Installation (optional)

Install the optional neoprene isolators at each mounting location. Isolators are identified by part number and color.

1. Secure the isolators to themounting surface, using the mounting slots in the isolator base plate, as shown in

Figure 39. Do not fully tighten the isolator mounting

bolts at this time.

2. Align the mounting holes in the base of the unit, with the threaded positioning pins on the top of isolators.

3. Lower the unit on to the isolators and secure the isolator to the unit with a nut. Maximum isolator deflection should be approximately 1/4”.

4. Level the unit carefully. Refer to “Leveling”. Fully tighten the isolator mounting bolts.

1. Set isolators on mounting surface, ensuring that all isolator centerlines match the submittal drawing. All isolator base plates (B) must be installed on a level surface. Shim orgrout as required, levelingall isolat(or base plates at the same elevation.

2. Anchor all isolators to the surface using thru holes (C) for concrete or (D) for steel as require. Welding to steel is permitted providing the weld achieves the required strength.

3. Remove clamp down nut (H) and washer (I). Isolators are shipped with (2) removable spacer shims (E) between the top plate and the housing.

Important: These shims MUST be in place when the

equipment is positioned over the isolators.

4. With all shims (E) in place, place the equipment onto the top plate (A) of the isolators.

5. Bolt equipment securely to the isolators using doubler plate (included in isolator kit), washer (I) and nut (H) as shown in Figure 44, p. 38.

Important: The following adjustment process can only

begin after the equipment or machine is at its full operating weight.

6. Back off each of the (2) or (4) limit stop locknuts (F) per isolator 1/4-3/8”.

7. Adjust each isolator in sequence by turning adjusting nut(s) (G) one full clockwise turn at a time. Repeat this procedure on all isolators, one at a time. check the limit stop locknuts (F) periodically to ensure that clearance between the washer and rubber grommet is maintained. Stop adjustment of an isolator only when the top plate (A) has risen just above the shim (E).

8. Remove all spacer shims (E).

9. Fine adjust isolators to level equipment.

10. Adjust all limit stop locknuts(F) per isolator to obtain 3/ 8” gap. the limit stop nuts must be kept at this 3/8” gap to ensure uniform bolt loading during uplift.

Evaporator Piping

Evaporator water connections are grooved.

Thoroughly flush all water piping to the CGAM unit before

making the final piping connections to the unit.

Components and layout will vary slightly, depending on the location of connections and the water source.

NOTICE:

Equipment Damage!

If using an acidic commercial flushing solution, construct a temporary bypass around the unit to prevent damage to internal components of the evaporator and the pump.

NOTICE:

Proper Water Treatment!

The use of untreated or improperly treated water could

result in scaling, erosion, corrosion, algae or slime. It is recommended that the services of a qualified water treatment specialist be engaged to determine what water treatment, if any, is required.Trane assumes no responsibility for equipment failures which result from untreated or improperly treated water, or saline or brackish water.

Figure 46. Water piping components

Drainage

Locate the unit near a large capacity drain for water vessel drain-down during shutdown or repair. Evaporators are provided with drain connections. Refer to “Water Piping.” All local and national codes apply.

A vent is provided on the top of the evaporator at the chilled water inlet. Be sure to provide additional vents at high points in the pipingto bleedair fromthe chilled water system. Install necessary pressure gauges to monitor the entering and leaving chilled water pressures.

Provide shutoff valves in lines to the gauges to isolate them from the system when they are not in use. Use rubber vibration eliminators to prevent vibration transmission through the water lines.

If desired, install thermometers in the lines to monitor entering and leaving water temperatures. Install a balancing valve in the leaving water line to control water flow balance. Install shutoff valves on both the entering and leaving water lines so that the evaporator can be isolated for service.

Evaporator Piping Components

Piping components include all devices and controls used to provide proper water system operation and unit operating safety. See Figure 46, p. 46.These components are listed below.

NOTICE:

Water Damage!

Standard pressure is 72.5 Psig for all factory installed components on the suction side of water pump. Standard pressure of components on the discharge side of water pump is 145 Psig.You MUST drain the system FIRST before releasing the pressure. Failure to do so could result in water spray which could cause equipment and/or property damage.

Water Strainer

The water strainer is factory-installed with taps for the

pressure gauges on the inlet and outlet. Install pressure gauges in order to measure differential pressure across the filter.This will help to determine when it is necessary to clean the water strainer.

Flow Switch

NOTICE:

Equipment Damage!

Flow switch is on a 24V circuit. Do NOT apply 120V to the flow switch. Incorrect voltage application could cause damage to the flow switch.

The flow switch is factory-installed and programmed

based on the operating conditions submitted with the order.The leaving evaporator temperature, fluid type and fluid concentration affect the selected flow switch. If the operating conditions on the job site change, the flow switch may need to be replaced.

The sensor head includes 3 LEDs, two yellow and one

green.Wait 15 seconds after poweris applied to the sensor before evaluating LEDs for flow status. When wired correctly and flow is established, only the green LED should be lit. Following are the LED indicators:

• Green ON, both yellow OFF — Flow

• Green and outside yellow ON — No Flow

• Center yellow ON continuously — Miswire

Factory installed jumper wire W11 must be removed if using auxiliary contacts and/or additional proof of flow. See schematics in CGAM-SVE01*-EN for more details.

Note: Use caution when connecting the auxiliary

contacts.Terminals 1X5-3 and 1X5-9 are to be used for field connections of auxiliary contacts. Inadvertant use of 1X5-4 and 1X5-9 will result in a FALSE FLOW indication.

NOTICE:

Equipment Damage!

Incorrect wiring of auxiliary contacts could cause equipment damage.

CG-SVX17E-EN 47

If using auxiliary flow sensing, both yellow LEDs come on initially when flow is stopped.The center yellow LED will turn off after approximately 7 seconds.The LED indicators are otherwise the same as indicated above.

Evaporator Label

The BPHE evaporator label, including barcode, is located

under the insulation, in the locations shown in Figure 47,

p. 48. Insulation backing over this area has not been

removed, so that it can be rolled back to access BPHE label.

Freeze Protection

Depending on the ambient temperature the unit may be exposed to, there are up to four different options for freeze protection.They are listed in order of highest ambient (least freeze protection) to lowest ambient (most freeze protection).

1. Water pump (for protection with ambient temperatures down to 0°F)

a. CH530 controller can start the pump when the

ambient temperatures drops to prevent freezing. For this option the pump must to be controlled by the CGAM unit and this function must be validated.

b. Water circuit valves need to stay open at all times.

Note: If dual high head pump package option is

selected, the chiller MUST control the pumps.

2. Heaters (for protection with ambient temperatures down to -20°F)

Note: This option is not applicable for units ordered

with “No Freeze Protection” (model number digit 18 is “X”). Factory mounted heaters are NOT installed on these units, and one of the other forms of freeze protection must be used.

a. For units with freeze protection selected (model

number digit 18is“1”), heaters are factory-installed on the evaporator and water pipingand will protect them from freezing in ambient temperatures down to -20°F (-29°C).

b. Install heat tape on all water piping, pumps, and

other components that maybe damaged if exposed to freezing temperatures. Heat tape must be designed for low ambient temperature applications. Heat tape selection should be based on the lowest expected ambient temperature.

NOTICE:

Equipment Damage!

All heaters have separate power from the unit. All

heaters must be energized or the CH530 must control the pumps when the unit is off (unless the water circuit is drained). In the event of power loss, neither heaters nor CH530 control of the pumps will protect the evaporator from catastrophic damage. In order to provide freeze protection in the event of a power loss you MUST drain the evaporator or use sufficient freeze inhibitor in the evaporator.

3. Freeze inhibitor

• Freeze protection can be accomplished by adding

sufficient glycol to protect against freezing below the lowest ambient expected.

• See “Low Evap Refrigerant Cutout/Percent Glycol

Recommendations,” p. 50.

4. Drain water circuit (for protection with ambients below

-20°F)

a. Shut off the power supply to the unit and to all

heaters.

b. Purge the water circuit.

c. Blow outthe evaporatorto ensureno liquid isleft in

the evaporator.

Note: By default the CH530 freeze protection control is

enabled and will request the start of the chilled water pump with ambient temperatures less than the evaporator low leaving water temperature setpoint.The pump remains ON until the minimum evaporator water temperature is greater than low leaving water temperature setpoint plus 7°C. The minimum on time for the pump is 5 minutes. If you do NOT want the CH530 to start the pump when the ambient temperature drops to freezing, disable this freeze protection control.

Low Evap Refrigerant Cutout/Percent Glycol Recommendations

The table below shows the low evaporator temperature

cutout for different glycol levels.

Additional glycol beyond the recommendations will adversely effect unit performance.The unit efficiency will be reduced and the saturated evaporator temperature will be reduced. For some operating conditions this effect can be significant.

If additional glycol is used, then use the actual percent glycol to establish the low refrigerant cutout setpoint.

Partial Heat Recovery

The partial heat recovery is comprised of an auxiliary heat

exchanger installed in the discharge line between the compressor and the air -cooled condenser.The heat exchangercools compressor dischargegas and rejects the energy to a separate water loop for hot water applications.

The chiller can simultaneously produce chilled and hot

water.

The heating capacity is driven by the cooling demand on

the chiller, the condensing temperature and the flow rate through the heat exchanger.

The partial heat recovery includes:

• Brazed plate heat exchanger

• Units 20-35Tons have a single braze plate heat

exchanger. Units 40-130Tons have two braze plate heat exchangers in parallel arrangement.

• Piping between the heat exchanger(s)

• Insulation of the heat exchanger(s) and water pipe

• Two temperature sensors to read the inlet/outlet hot water temperature information on the unit control display

• Heater on partial heat recovery heat exchanger(s) and water pipe

• Manual air vent

• Drain pipe

Water circulating inside the heat recovery heat exchanger

should never be used for drinking water, it must be used through an indirect loop to heat or preheat hot water.

Important: The installation must comply with the rules

and legislation applicable at the jobsite location regarding the use of drinkable water.The use of the water circulating in the heat recovery exchanger as drinkable water is not recommended. An intermediate heat exchanger should be used.

The partial heat recovery pump must run at least three

minutes after the partial heat recovery fan control is disabled. During thethree minutes, water flow through the brazed plate heat exchanger will gradually be reduced and the unit can be switched to conventional cooling mode without partial heat recovery fan control.

Partial Heat Recovery Piping

A field installed safety or relief valve on the water side is required with the partial heat recovery to prevent risks resulting from a failure of the thermostat.

A 16 mesh strainer must be installed close to the partial heat recovery heat exchanger entering water line to protect the heat exchanger.

The partial heat recovery water temperature should be

controlled via an external devise such as a 3-way valve or variable speed pump. In addition, a water tank and additional heater is suggested in the partial heat recovery loop.

Insulate water lines and other portions of the heatrecovery water loop to prevent heat loss and potential injury due exposure to a hot surface.

For recommended partial heat recovery piping see

Figure 56, p. 55.

NOTICE:

Proper Water Treatment!

The use of untreated or improperly treated water could

NOTICE:

Equipment Damage!

Do not use untreated or improperly treated water in the heat recovery water loop since it will cause inefficient operation and potential damage to the unit such as: reduced heat transfer between water and refrigerant, increased water pressure drop and reduced water flow.

NOTICE:

Equipment Damage!

If the partial heat recovery heat exchanger is drained the heater must be turned off to avoid damaging the partial heater recovery heat exchanger. The heater should only be on when the heat recovery heat exchanger has water in it.

Figure 56. Partial Heat Recovery Piping Recommendations

CGAM Unit

Note: In addition to those recommended for field piping, the CGAM unit includes factory installed manual air vent and

water drain valve with partial heat recovery option. See Figure 81, p. 96 through Figure 83, p. 97 for partial heat recovery component locations.

Partial Heat Recovery Freeze Protection

The heat recovery condenser is insulated and a factory-

installed heater is installed and will protect the heat exchangerfrom freezing in ambienttemperatures down to

-20°F (-29°C).

When the ambient temperature drops to approximately

39°F (3.9°C) the thermostat energizes the heaters.

Note: The inlet and outlet piping should be protected

against freezing by one of the following methods:

• Install heat tape on all field-installed water piping.

• Add freeze inhibit fluid to the partial heat recovery water loop.

Dual High Head Pump Package

Pump package includes: two high head pumps, VFD, expansion vessels, drainage valves, shut-off valves at entering and leaving connections. See Figure 60.

The pump package is single point power integrated into

the chiller unit power with aseparate factorywired control panel.The control of the pump is integrated into the chiller controller.

Important: When pump package is selected, the chiller

MUST control the pumps.

The CH530 displays evaporator pump starts and run-

times. Freeze protection down to an ambient of

-20°F (-29°C) is included as standard.The cold parts of the

pump package will also be insulated. Designed with one redundant pump, the chiller controls both pumps through a lead/lag and failure/recovery functionality.

A variable speed drive is installed in an additional panel to control the pump.The inverter should be adjusted by the customer upon start up to balance the system flow and head requirements.The purpose is to save on wasted pump energy caused by a traditional balancing valve.

Note: Speed command is also available for customer-

provided variable flow input.

General Recommendations

All wiring must comply with local codes and the National Electric Code.Typical field wiring diagrams are included at the end of the manual. Minimum circuit ampacities and other unit electricaldata are on theunit nameplate. See the unit order specifications for actual electrical data. Specific electrical schematics and connection diagrams are shipped with the unit.

WARNING

Hazardous Voltage!

Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/ tagout procedures to ensure the power can not be inadvertently energized. Failure to disconnect power before servicing could result in death or serious injury.

NOTICE:

Use Copper Conductors Only!

Unit terminals are not designed to accept other types of conductors. Failure to use copper conductors could result in equipment damage.

NOTICE:

Equipment Damage!

Do not allow conduit to interfere with other components, structural members or equipment. Control voltage (115V) wiring in conduit must be separate from conduit carrying low voltage (<30V) wiring.To prevent control malfunctions, do not run low voltage wiring (<30V) in conduit with conductors carrying more than 30 volts.

conduits and connected to the terminal blocks or HACR type breakers. Refer to Table 35.

To provide proper phasing of 3-phase input, make

connections as shown in field wiring diagrams and as stated on the WARNING label in the starter panel. For additional information on proper phasing, refer to “Unit

Voltage Phasing,” p. 122. Proper equipment ground must

be provided to each ground connection in the panel (one for each customer-supplied conductor per phase).

The high voltage field-provided connections are made

through knockouts on the right side of the panel.The low voltage connections are made through the left side of the panel (Figure 35). Additional grounds may be required for each 115 volt power supply to the unit. Green lugs are provided for 115V customer wiring.

Control Power Supply

The unit is equipped with a control power transformer; it

is not necessary to provide additional control power voltage to the unit. No other loads should be connected to the control power transformer.

All units are factory-connected for appropriate labeled

voltages.

NOTICE:

Equipment Damage!

Control panel main processor does not check for loss of power to the heat tape nor does it verify thermostat operation. A qualified technician must verify power to the heat tape and confirm operation of the heat tape thermostat to avoid catastrophic damage to the evaporator or partial heat recovery heat exchanger.

Heater Power Supply

For units with freeze protection selected (model number digit 18 is “1”), the evaporator shell is insulated from ambient air and protected from freezing temperatures by a thermostatically-controlled immersion heaters. When the ambient temperature drops to approximately 37°F (2.8°C) the thermostat energizes the heaters.The heaters will provide protection from ambient temperatures down to -20°F (-29°C).

It is required to provide an independent power source (115V 60-Hz-20 amp, 50Hz-15 amp), with a fuseddisconnect to the heaters.The heaters are factory-wired back to the unit control panel.

Note: If evaporator is drained, the heater must be turned

off in order to avoid damaging the evaporator.The heater should only be on when the evaporator has water in it.

Knock-outs for wiring are located on the bottom right side of the control panel.The wiring is passed through these

Installation - Electrical

InterconnectingWiring

Chilled Water Flow (Pump) Interlock

All CGAM model chillers have a factory-installed flow switch. In addition, it isrecommended to usean additional field-supplied control voltage contact input through an auxiliary contact to prove flow. Connect the auxiliary contact to 1X5-3 and 1X5-9. Refer to the field wiring for details.The auxiliary contact can be a BAS signal, starter contactor auxiliary or any signal which indicates the pump is running.

Chilled Water Pump Control

An evaporator water pump output relay closes when the chiller is given a signal to go into the Auto mode of operation from any source.The contact is opened to turn off the pump in the event of most machine level diagnostics to prevent the build up of pump heat.

The relay output from 1A9 is required to operate the

EvaporatorWater Pump (EWP) contactor. Contacts should be compatible with 115/240 VAC control circuit. Normally, the EWP relay follows the AUTO mode of the chiller.

Whenever the chiller has nodiagnostics and is inthe AUTO

mode, regardless of where the auto command is coming from, the normally open relay is energized. When the chiller exits the AUTO mode, the relay is timed to open in an adjustable (usingTechView) 0 to 30 minutes.The nonAUTOmodes in which the pumpis stopped, include Reset, Stop, External Stop, Remote Display Stop, Stopped by

Tracer, Start Inhibited by Low AmbientTemp, and Ice

Building complete.

NOTICE:

Equipment Damage!

If the microprocessor calls for a pump to start and water does not flow, the evaporator may be damaged catastrophically. It is the responsibility of the installing contractor and/or the customer to ensure that a pump will always be running when called upon by the chiller controls.

Table 36. Pump Relay Operation

Chiller Mode Relay Operation

Auto Instant close

Ice Building Instant close

Tracer Override Close

Stop Timed to Open

Ice Complete Instant Open

Diagnostics Instant Open

When going from Stopto Auto, the EWP relay is energized

immediately. If evaporator water flow is not established in 4 minutes and 15 seconds, the CH530 de-energizes the

EWP relay and generates a non-latching diagnostic. If flow returns (e.g. someone else is controlling the pump), the diagnostic is cleared, the EWP relay is re-energized, and normal control resumed.

If evaporator water flow is lost once it has been established, the EWP relay remains energized and a nonlatching diagnostic is generated. If flow returns, the diagnostic is cleared and the chiller returns to normal operation.

NOTICE:

Equipment Damage!

Do NOT enable/disable the chiller by removing water flow or equipment damage can occur.

In general, when there is either a non-latching or latching diagnostic, the EWP relayis turned off as thoughthere was a zero time delay.The relay continues to be energized with:

A Low Chilled WaterTemperature diagnostic (non-

latching) unless also accompanied by an Evap Leaving

WaterTemperature Sensor Diagnostic.

A Loss of EvaporatorWater Flow diagnostic (non-latching)

and the unit is in the AUTO mode, after initially having proven evaporator water flow.

Note: If pump control is used for freeze protection then

the pump MUST be controlled by the CGAM CH530 control. If another method of freeze protection is used (i.e. glycol, heaters, purge, etc) then the pump may be controlled by another system.

Chilled Water Pump Control - Field Supplied Dual Pumps

CH530 can provide pump control for two customersupplied pumps, as long as the pump contactor coils 1A9 and connect the pump fault feedback signals 1A12 are properly connected.

In this situation, the unit will leave the factory with Evaporator Pump Control (EVPC) = No Pump Control (Pump Request Relay) (NPMP) and Evaporator Pump Fault Input (EVFI) = Installed (INST).When the contactors and pumps are set up in the field, the CH530 ServiceTool (TechView) must be used to reconfigure to Evaporator Pump Control = Dual Pump Fixed Speed and Evaporator Pump Fault Input = Not Installed or Installed depending on how the fault feedback wire is connected. It is strongly recommended to install the Fault Input if possible as the controls will “hot-swap” the pumps upon detection of a fault, and may avoid the inevitable Flow Loss diagnostic (and unit shutdown) that will result if there is no fault feedback.

72 CG-SVX17E-EN

Page 73

Installation - Electrical

When configured for Dual Pump Fixed Speed, the CH530

will swap pumps on detection of a fault (if installed), or when a flow loss or overdue event occurs. It will also switch pumps each time the overall pump request is removed and re-engaged,unless a fault is detected on one of the pumps.If faults are detectedon both pumps,the unit will be shut down.

In addition to the factory installed flow switch, a fieldsupplied auxiliary contact is required, so that the chiller will only detect flow if a pump is running and the flow switch says flow is present.

Chilled Water Pump Control - Optional Pump Package

When factory installed pump package option is selected,

the chiller MUST control the pumps. See “Chilled Water

Pump Control,” p. 72.

Alarm and Status Relay Outputs

(Programmable Relays)

A programmable relay concept provides for enunciation of

certain events or states of the chiller, selected from a list of likely needs, while only using four physical output relays, as shown in the field wiring diagram.The four relays are provided (generally witha Quad Relay Output LLID) as part of theAlarm Relay Output Option.The relay’s contacts are isolated Form C (SPDT), suitable for use with 120 VAC circuits drawing up to 2.8 amps inductive, 7.2 amps resistive, or 1/3 HP and for 240VAC circuits drawing up to

0.5 amp resistive.

The list of events/states that can be assigned to the

programmable relays can be found in Table 37.The relay will be energized when the event/state occurs.

. This classification does not include informational diagnostics.

Relay Assignments Using TechView

CH530 ServiceTool (TechView) is used to install the Alarm and Status Relay Option package and assign any of the above list of events or status to each of the four relays provided with the option.The relays to be programmed are referred to by the relay’s terminal numbers on the LLID board 1A18.

The default assignmentsfor the four availablerelays of the

CGAM Alarm and Status Package Option are:

Low VoltageWiring

NOTICE:

WARNING

Proper Field Wiring and Grounding Required!

All field wiring MUST be performed by qualified

The remote devices described below require low voltage

wiring. All wiring to and from these remote input devices to the Control Panel must be made with shielded, twisted pair conductors. Be sure to ground the shielding only at the panel.

Note: To prevent control malfunctions, do not run low

voltage wiring (<30 V) in conduit with conductors carrying more than 30 volts.

Emergency Stop

CH530 provides auxiliary control for a customer specified/ installed latching trip out. When this customer-furnished remote contact 6K5 is provided, the chiller will run normally when the contact is closed. When the contact opens, the unit will trip on a manually resettable diagnostic.This condition requires manual reset at the chiller switch on the front of the control panel.

Connect low voltage leads to terminal strip locations on 1A13, J2-3 and 4. Refer to the field diagrams that are shipped with the unit.

Silver or gold-plated contacts are recommended.These customer-furnished contacts must be compatible with 24

VDC, 12 mA resistive load.

External Auto/Stop

If the unit requires the external Auto/Stop function, the installer must provide leads from the remote contact 6K4 to the proper terminals on 1A13, J2-1 and 2.

The chiller will run normally when the contact is closed. When the contact opens, the compressor(s), if operating,

will go to the RUN:UNLOAD operating mode and cycle off. Unit operation willbe inhibited. Closure of the contact will permit the unit to return to normal operation.

Field-supplied contacts for all low voltage connections must be compatible with dry circuit 24 VDC for a 12 mA resistive load. Refer to the field diagrams that are shipped with the unit.

Equipment Damage!

Do NOT enable/disable the chiller by removing water flow or equipment damage can occur.

Ice Building Option

CH530 provides auxiliary control for a customer specified/ installed contact closure for ice building if so configured and enabled.This output is known as the Ice Building Status Relay. The normally open contact will be closed when ice building is in progress and open when ice building has been normally terminated either through Ice

Termination setpoint being reached or removal of the Ice

Building command. When contact 6K6 is provided, the chiller will run normally when the contact is open.

CH530 will accept either an isolated contact closure (External Ice Building command) or a Remote Communicated input (Tracer) to initiate andcommand the Ice Building mode.

CH530 also provides a “Front Panel IceTermination Setpoint”, settable throughTechView, and adjustable from 20 to 31°F (-6.7 to -0.5°C) in at least 1°F (1°C) increments.

When in the Ice Building mode, and the evaporator

entering water temperature drops below the ice termination setpoint, the chiller terminates the Ice Building mode and changes to the Ice Building Complete Mode.

NOTICE:

Evaporator Damage!

Freeze inhibitor must be adequate for the leaving water temperature. Failure to do so may result in damage to system components.

TechView may also be used to enable or disable Ice

Machine Control.This setting does not prevent theTracer from commanding Ice Building mode.

Upon contact closure, the CH530 will initiate an ice building mode, in which the unit runs fully loaded at all times. Ice building shall be terminated either by opening the contact or based on the entering evaporator water temperature. CH530 will not permit the ice building mode to be reentered until the unit has been switched out of ice building mode (open 5K20 contacts) and then switched back into ice building mode (close 5K20 contacts.)

In ice building, all limits (freeze avoidance, evaporator, condenser, current) will be ignored. All safeties will be enforced.

If, while in ice building mode, the unit gets down to the freeze stat setting (water or refrigerant), the unit will shut down on a manually resettable diagnostic, just as in normal operation.

Installation - Electrical

Connect leads from 6K6 to the proper terminals of 1A16. Refer to the field diagrams which are shipped with the unit.

Silver or gold-plated contacts are recommended.These customer furnished contacts must be compatible with 24

VDC, 12 mA resistive load.

External Chilled Water Setpoint (ECWS) Option

The CH530 provides inputs that accept either 4-20 mA or 2-

10 VDC signals to set the external chilled water setpoint (ECWS).This is not a reset function.The input defines the set point.This input is primarily used with generic BAS (building automation systems).The chilled water setpoint set via the DynaView or through digital communication withTracer.

The chilled water setpoint may be changed from a remote

location by sending either a 2-10VDC or 4-20 mA signal to the 1A14, J2-1 and 2.The 2-10 VDC and 4-20 mA each correspond to a 10 to 65°F (-12 to 18°C) external chilled water setpoint.

The following equations apply:

Voltage Signal

VDC = (8*ECWS

Current Signal

mA = (16*ECWS

Note: To convert ECWS values to °F, use the following

If the ECWS input develops an open or short, the LLID will report either a very high or very low valueback to the main processor.This will generate an informational diagnostic and the unit will default to using the Front Panel (DynaView) Chilled Water Setpoint.

TechView ServiceTool is used to set the input signal type

from the factory default of 2-10 VDC to that of 4-20 mA.

TechView is also used to install or remove the External

ChilledWater Setpoint option aswell asa meansto enable and disable ECWS.

The minimum EDLS will be clamped at the front panel

based on 100% /Total number of Compressors. For input signals beyond the 2-10VDC or 4-20mA range, the end of range value shall be used. For example, if the customer inputs 21 mA, the EDLS shall limit it self to the corresponding 20 mA EDLS.

ECWS and EDLS Analog Input Signal

Wiring Details:

Both the ESWS and EDLS can be connected and setup as either a 2-10 VDC (factory default), 4-20 mA, or resistance input (also a form of 4-20 mA) as indicated below. Depending on the type to be used, theTechView Service

Tool must be used to configure the LLIDand the MPfor the

proper input type that is being used.This is accomplished by a setting change on the Custom Tab of the Configuration View withinTechView.

The J2-3 and J2-6 terminal is chassis grounded and

terminal J2-1 and J2-4 can be used to source 12VDC.The ECLS uses terminals J2-2 and J2-3. EDLS uses terminals

)

J2-5 and J2-6. Both inputs are only compatible with high-side current sources.

Figure 67. Wiring Examples for ECLS and EDLS

External Demand Limit Setpoint (EDLS) Option

CH530 provide a means to limit the capacity of the chiller by limiting the number of compressors or stages that are allowed to run.The maximum number of compressor or stages allowed to run can vary from one to the number of stages on the unit.The staging algorithm is free to decide which compressor or stage shall be turned off or prevented from running to meet this requirement.

CH530 shall accept either a 2-10 VDC or 4-20 mA analog input suitable for customer connection to set the unit external demand limit setpoint (EDLS).

Chilled Water Reset (CWR)

CH530 resets the chilled water temperature set point based on either return water temperature, or outdoor air temperature.

The following shall be selectable:

• One of three ResetTypes: None, Return Water

Temperature Reset, Outdoor AirTemperature Reset, or

Constant Return WaterTemperature Reset.

• Reset Ratio Set Points.

• For outdoor air temperature reset there shall be both positive and negative reset ratio's.

• Start Reset Set Points.

• Maximum Reset Set Points.

The equations for each type of reset are as follows:

Return

CWS' = CWS + RATIO (START RESET - (TWE -TWL))

and CWS' > or = CWS

and CWS' - CWS < or = Maximum Reset

Outdoor

CWS' = CWS + RATIO * (START RESET -TOD)

and CWS' > or = CWS

and CWS' - CWS < or = Maximum Reset

where

CWS' is the new chilled water set point or the "reset CWS"

CWS is the active chilled water set point before any reset has occurred, e.g. normally Front Panel, Tracer, or ECWS

RESET RATIO is a user adjustable gain

START RESET is a user adjustable reference

TOD is the outdoor temperature

TWE is entering evap. water temperature

TWL is leaving evap. water temperature

MAXIMUM RESET is a user adjustable limit providing the maximum amount of reset. For all types of reset, CWS' CWS < or = Maximum Reset.

the same as the Return Reset equation except on selection of Constant Return Reset, the MP will automatically set Ratio, Start Reset, and Maximum Reset to the following.

RATIO = 100%

START RESET = Design DeltaTemp.

MAXIMUM RESET = Design DeltaTemp.

The equation for Constant Return is then as follows:

CWS' = CWS + 100% (Design DeltaTemp. - (TWE -TWL))

and CWS' > or = CWS

and CWS' - CWS < or = Maximum Reset

When any type of CWR is enabled, the MP will step the Active CWS toward the desired CWS' (based on the above

equations and setup parameters) at a rate of 1 degree F every 5 minutes until the Active CWS equals the desired CWS'.This applies when the chiller is running.

When the chiller is not running the CWS is reset

immediately (within one minute) for Return Reset and at a rate of 1 degree F every 5 minutes for Outdoor Reset.The chiller will start at the Differential to Start value above a fully reset CWS or CWS' for both Return and Outdoor Reset.

Percent Capacity Output Option

CH530 provides an optional percent capacity output for those customers without a communicating BAS interface.

The active unit capacity (AUC) is provided through a 2-10

VDC analog output at 1A25 terminals J2-4 andJ2-6 (GND).

The active unit capacity value (in %) can be derived from

the 2-10 VDC output voltage (OV) using the following calculation:

AUC = 100*(OV - 2.0V)/(10.0V - 2.0V)

Note: The percent capacity output is based on the

number and size of compressors energized, and is not adjusted for operating conditions. This value cannot be used as an accurate measure of total unit current, power or cooling capacity.

Object Name Description

Indicates if the chiller is being controlled by local setpoints instead of BAS setpoints.

Indicates if conditions may exist that prevent the chiller from reaching setpoint.

Indicates a request from the chiller to turn on the evaporator water pump.

Indicates a request from the chiller to turn on the condenser water pump.

BCI-C Alarming

The BCI-C unit has three binary input points that are used

for communicating alarms and one binary output point that is used to reset alarms remotely.Those inputs and output points are:

• BI 23; Alarm Present–This object indicates if any alarms are active regardless of severity. A notification will be sent to any recipients of the Information Notification Class object when the point transitions from No Alarm to Alarm.

• BI 24; Shutdown Alarm Present– This object indicates if any alarms that result in the shutdown of the chiller are active. A notification will be sent to any recipients of the Critical Notification Class object when the point transitions from No Alarm to Alarm.

• BI 25; Last Diagnostic–The active text of this object will reflect the description of the last diagnostic to occur on the chiller.

• BO 2; Remote Diagnostic Reset Command–This object is used to remotely reset diagnostics on the chiller. Immediately aftercommanding this point value to 1, the BCI-C will send the reset command to the chiller and set this point value back to 0 and clear the priority array.

Note: Not all diagnostics are able to be reset remotely.

Some will require local reset at the chiller front panel.

The refrigeration cycle of the Model CGAM chiller is

conceptually similar to otherTrane air-cooled chiller products.The CGAM chiller uses a brazed plate evaporator and an air-cooled condenser.The compressors use suction gas cooled motors and an oil management system to provide almost oil-free refrigerant to the condenser and evaporator for maximum heat transfer while lubricating and sealing compressor bearings.The lubrication system helps to assure long compressor life and contributes to quiet operation.

Refrigerant condensers in the air-cooled heat exchanger which is available in three configurations—slant, V and

W—based on the CGAM nominal tonnage cooling

capacity.Liquid refrigerant ismetered intothe brazed plate evaporator using an electronic expansion valve to maximize chiller efficiency at full and part load operation.

The CGAM chiller is equipped with a unit-mounted starter

and control panel. Microprocessor-based unit control

2.) Partial heat recovery option with fan control function.

modules (TraneTracer™CH530) provide accurate chilled water control and provide monitoring, protection and adaptive limit functions.The adaptive nature of the controls intelligently prevent the chiller from operating outside of its limits, or compensates forunusual operating conditions while keeping the chiller running rather than simply shutting off the chiller. If problems do occur, the CH530 controls provide diagnostic messages to help the operator in troubleshooting.

Refrigerant Cycle Description

The CGAM refrigeration cycle is described using the

pressure-enthalpy chart shown in Figure 84 Key State Points 1 through 5 are indicated on the chart. A schematic showing refrigerant components throughout the system is shown in Figure 85.

Refrigerant evaporation occurs in the brazed plate evaporator. Metered refrigerant vaporizes as it cools the chilled water or liquid flowing through the evaporator

passages.The refrigerant vapor leaves the evaporator as superheated gas. State Point 1.

Refrigerant vapor generated in the evaporator flowsto the compressor suction manifold where it enters and flows across the compressormotor windings toprovide cooling.

The vapor is then compressed in the compressor scroll

chambers and discharged. Oil from the compressor sump lubricates the bearings and seals the small clearances between the compressor scrolls. Refrigerant vapor is discharged to the air-cooled condenser at State Point 2.

After the refrigerant vapor condenses into liquid (State Points 3 and 4) it is returned to the evaporator (State Point

5) where the refrigerant again flashes into vapor and the refrigeration cycle repeats.
