WARNING
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.
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 local Trane 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.

General Information
Unit Description
Figure 3.
CGAM “V” 40-70Ton configuration
Figure 4.
CGAM “W” 80-130T configuration
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
Installation Requirements
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.
A list of the contractor responsibilities typically associated
with the unit installation process is provided.
Inspect all exterior components for visible damage. 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 proceed with installation of a damaged unit without
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.
•
Type
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.

Installation - Mechanical
Location Requirements
Lifting Procedure
WARNING
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 be supported 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 service points. 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.
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.
Rigging
Refer to Unit Dimensions/Weights section for typical unit
lifting weights. Refer to the rigging label attached to the
unit for further details.
•
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 the H bar must be adjusted to produce a level
unit lift. See Figure 34, p. 33 for illustration.

Unit Isolation and Leveling
Table 10.
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 the mounting surface, using the
mounting slots in the isolator base plate, as shown in
Figure 38. 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. Level the unit carefully.
Refer to “Leveling”. Fully tighten the isolator mounting
bolts.

isolator centerlines match the submittal drawing. All
isolator base plates (B) must be installed on a level
surface. Shim or grout as required, leveling all 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.
WASHER
Important: These shims MUST be in place when the
equipment is positioned over the isolators.

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

Evaporator Piping
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.
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!
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 piping to bleed air from the chilled water
system. Install necessary pressure gauges to monitor the
entering and leaving chilled water pressures.
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.
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.
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.
Evaporator Piping Components
Piping components include all devices and controls used
to provide proper water system operation and unit
operating safety. See Figure 45, p. 46.These components
are listed below.

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.
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
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.
Indexing Flow Switch
To properly index the flow switch, the following
requirements must be met:
•
The dot must be at a position no greater than 90° off
Index.
•
The torque must be between 22 ft-lb minimum and 74
ft-lb maximum.
•
A minimum distance of 5x pipe diameter must be
maintained between flow switch and any bends,
valves, changes in cross sections, etc.

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 power is applied to the sensor
before evaluating LEDs for flow status. When wired

Freeze Protection
OR
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).
3. Freeze inhibitor
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.
OR
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 18 is “1”), heaters are factory-installed
on the evaporator and water piping and 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 may be 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 or sufficient glycol is used). 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.
50
• 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.
OR
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 out the evaporator to ensure no liquid is left 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.

Installation - Mechanical
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
exchanger cools compressor discharge gas 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.
•
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 heat recovery
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.
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 the three 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.
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.
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 factoryinstalled heater is installed and will protect the heat
exchanger from freezing in ambient temperatures 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.
OR
•
Add freeze inhibit fluid to the partial heat recovery
water loop.

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 electrical data are on the unit 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.

Interconnecting Wiring
Chilled Water Flow (Pump) Interlock
All CGAM model chillers have a factory-installed flow
switch. In addition, it is recommended to use an 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.
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.
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 no diagnostics and is in the 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 nonAUTO modes in which the pump is stopped, include Reset,
Stop, External Stop, Remote Display Stop, Stopped by
Tracer, Start Inhibited by Low AmbientTemp, and Ice
Building complete.
t
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.

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 relay is turned off as though there was
a zero time delay.The relay continues to be energized with:
A Low Chilled WaterTemperature diagnostic (nonlatching) unless also accompanied by an Evap Leaving
WaterTemperature Sensor Diagnostic.
or
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.
CG-SVX17F-EN
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 detected on both pumps, the unit
will be shut down.
Alarm and Status Relay Outputs
(Programmable Relays)
Chilled Water Pump Control - Optional
Pump Package
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 with a Quad Relay Output LLID) as part
of the Alarm 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 240 VAC circuits drawing up to
0.5 amp resistive.
When factory installed pump package option is selected,
the chiller MUST control the pumps. See “Chilled Water
Pump Control,” p. 72.
The list of events/states that can be assigned to the
programmable relays can be found in Table 38.The relay
will be energized when the event/state occurs.
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.

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 will be 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.

NOTICE:
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 and command 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.
CG-SVX17F-EN
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 210 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 2-10 VDC 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°F + 2*ECWSmax - 10*ECWSmin)/(ECWSmax - ECWSmin)
Current Signal
mA =
(16*ECWS°F + 4*ECWSmax - 20*ECWSmin)/ (ECWSmax - ECWSmin)
Note: To convert ECWS values to °F, use the following
formula: °F = 1.8*(°C) + 32
2-10 VDC and 4-20 mA shall each correspond to an EDLS
range with a minimum of 0% and a maximum of 100%.The
following equations exist.
Global Scroll
Voltage Signal
Current Signal
As generated from
external source
Vdc = 8*(EDLS) + 2 mA = 16*(EDLS) + 4
As processed by
CH530
EDLS = (Vdc - 2)/8
EDLS = (mA - 4)/16
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 LLID and the MP for the
proper input type that is being used.This is accomplished
by a setting change on the CustomTab 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 12 VDC.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
If the ECWS input develops an open or short, the LLID will
report either a very high or very low value back 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 as well as a means to enable
and disable ECWS.
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 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%
The following shall be selectable:
START RESET = Design DeltaTemp.
•
MAXIMUM RESET = Design DeltaTemp.
One of three ResetTypes: None, Return Water
Temperature Reset, Outdoor AirTemperature Reset, or
Constant Return WaterTemperature Reset.
The equation for Constant Return is then as follows:
•
Reset Ratio Set Points.
and CWS' > or = CWS
•
For outdoor air temperature reset there shall be both
positive and negative reset ratio's.
and CWS' - CWS < or = Maximum Reset
•
Start Reset Set Points.
•
Maximum Reset Set Points.
The equations for each type of reset are as follows:
Return
CWS' = CWS + 100% (Design DeltaTemp. - (TWE -TWL))
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.
CWS' = CWS + RATIO (START RESET - (TWE -TWL))
and CWS' > or = CWS
and CWS' - CWS < or = Maximum Reset
Outdoor
CWS' = CWS + RATIO * (START RESET -TOD)
Percent Capacity Output Option
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
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 and J2-6 (GND).
The active unit capacity value (in %) can be derived from
the 2-10 VDC output voltage (OV) using the following
calculation:
RESET RATIO is a user adjustable gain
START RESET is a user adjustable reference
AUC = 100*(OV - 2.0V)/(10.0V - 2.0V)
TOD is the outdoor temperature
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.
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 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.

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 for unusual 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
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 is metered into the brazed plate
evaporator using an electronic expansion valve to
maximize chiller efficiency at full and part load operation.
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.
The CGAM chiller is equipped with a unit-mounted starter
and control panel. Microprocessor-based unit control
Refrigerant evaporation occurs in the brazed plate
evaporator. Metered refrigerant vaporizes as it cools the
chilled water or liquid flowing through the evaporator
98
CG-SVX17F-EN
CGAM Operating Principles
Refrigerant vapor generated in the evaporator flows to the
compressor suction manifold where it enters and flows
across the compressor motor windings to provide 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

Oil System Operation (CGAM)
Overview
The oil is efficiently separated inside the scroll compressor
and will remain in the scroll compressor during all run
cycles. Between 1-2% of the oil circulates around with the
refrigerant.

CH530 Communications
Overview
TheTrane CH530 control system that runs the chiller
consists of several elements:
•
•
The main processor collects data, status, and
diagnostic information and communicates commands
to the starter module and the LLID (for Low Level
Intelligent Device) bus.The main processor has an
integral display (DynaView).
DynaView Interface
The DynaView enclosure design is weatherproof and
made of durable plastic for use as a device on the outside
of the unit.
The display on DynaView is a 1/4 VGA display with a
resistive touch screen and an LED backlight.The display
area is approximately 4 inches wide by 3 inches high
(102mm x 60mm).
Key Functions
Low level intelligent device (LLID) bus.The main
processor communicates to each input and output
device (e.g. temperature and pressure sensors, low
voltage binary inputs, analog input/output) all
connected to a four-wire bus, rather than the
conventional control architecture of signal wires for
each device.
In this touch screen application, key functions are
determined completely by software and change
depending upon the subject matter currently being
displayed.The basic touch screen functions are outlined
below.
•
The communication interface to a building automation
system (BAS).
•
A service tool to provide all service/maintenance
capabilities.
Radio buttons show one menu choice among two or more
alternatives, all visible.The radio button model mimics the
buttons used on old-fashioned radios to select stations.
When one is pressed, the one that was previously pressed
“pops out” and the new station is selected. In the
DynaView model the possible selections are each
associated with a button.The selected button is darkened,
presented in reverse video to indicate it is the selected
choice.The full range of possible choices as well as the
current choice is always in view.
Main processor and service tool (TechView) software is
downloadable from www.trane.com.The process is
discussed later in this section underTechView Interface.
DynaView provides bus management. It has the task of
restarting the link, or filling in for what it sees as “missing”
devices when normal communications has been
degraded. Use ofTechView may be required.
The CH530 uses the IPC3 protocol based on RS485 signal
technology and communicating at 19.2 Kbaud to allow 3
rounds of data per second on a 64-device network. A
typical four-compressor CGAM will have around 30
devices.
Most diagnostics are handled by the DynaView. If a
temperature or pressure is reported out of range by a LLID,
the DynaView processes this information and calls out the
diagnostic.The individual LLIDs are not responsible for
any diagnostic functions.
Note: It is imperative that the CH530 ServiceTool
(TechView) be used to facilitate the replacement of
any LLID or reconfigure any chiller component.
TechView is discussed later in this section.
Controls Interface
Each chiller is equipped with a DynaView interface.The
DynaView has the capability to display information to the
operator including the ability to adjust settings. Multiple
screens are available and text is presented in multiple
languages as factory-ordered or can be easily downloaded
from www.trane.com.
TechView can be connected to the DynaView module and
provides further data, adjustment capabilities, diagnostics
information using downloadable software.
CG-SVX17F-EN
Radio Buttons
Spin Value Buttons
Spin values are used to allow a variable setpoint to be
changed, such as leaving water setpoint.The value
increases or decreases by touching the increment (+) or
decrement (-) arrows.
Action Buttons
Action buttons appear temporarily and provide the user
with a choice such as Enter or Cancel.
Hot Links
Hot links are used to navigate from one view to another
view.
File Folder Tabs
File folder tabs are used to select a screen of data. Just like
tabs in a file folder, these serve to title the folder/screen
selected, as well as provide navigation to other screens. In
DynaView, the tabs are in one row across the top of the
display.The folder tabs are separated from the rest of the
display by a horizontal line.Vertical lines separate the tabs
from each other.The folder that is selected has no
horizontal line under its tab, thereby making it look like a
part of the current folder (as would an open folder in a file
cabinet).The user selects a screen of information by
touching the appropriate tab.

The file folder tabs across the top of the screen are used to
select the various display screens.
The Auto and Stop keys will be presented as radio buttons
within the persistent key display area.The selected key
will be black.
The chiller will stop when the Stop key is touched, entering
the Run Unload mode. An informational screen will be
displayed for 5 seconds indicating that a second
depression of an “Immediate Stop” key during this time
period will result in an immediate stop. Pressing the
“Immediate Stop” key while the immediate stop screen is
displayed, will cause the unit to stop immediately,
skipping operational pumpdown.
Scroll arrows are added if more file tabs (choices) are
available. When the tabs are at the left most position, the
left navigator will not show and only navigation to the right
will be possible. Likewise when the right most screen is
selected, only left navigation will be possible.
The main body of the screen is used for description text,
data, setpoints, or keys (touch sensitive areas).The Chiller
Mode is displayed here.
The double up arrows cause a page-by-page scroll either
up or down.The single arrow causes a line by line scroll to
occur. At the end of the page, the appropriate scroll bar will
disappear.
A double arrow pointing to the right indicates more
information is available about the specific item on that
same line. Pressing it will bring you to a subscreen that will
present the information or allow changes to settings.
The bottom of the screen (Fixed Display) is present in all
screens and contains the following functions.The left
circular area is used to reduce the contrast/viewing angle
of the display.The right circular area is used to increase
the contrast/viewing angle of the display.The contrast
may require re-adjustment at ambient temperatures
significantly different from those present at last
adjustment.
The other functions are critical to machine operation.The
AUTO and STOP keys are used to enable or disable the
chiller.The key selected is in black (reverse video).The
chiller will stop when the STOP key is touched and after
completing the Shutting Down mode.
Touching the AUTO key will enable the chiller for active
cooling if no diagnostic is present. (A separate action must
be taken to clear active diagnostics.)
102
NOTICE:
Equipment Damage!
Do NOT enable/disable the chiller by removing water
flow or equipment damage can occur.
Touching the Auto key will arm the chiller for active cooling
if no diagnostic is present. As in UCP2, a separate action
must be taken to clear active diagnostics.
The AUTO and STOP, take precedence over the ENTER and
CANCEL keys. (While a setting is being changed, AUTO
and STOP keys are recognized even if ENTER or CANCEL
has not been pressed.
Diagnostic Annunciation
When an active diagnostic is present, an Alarms key will be
added to the persistent display area.This key will serve
two purposes.The first purpose will be to alert the
CG-SVX17F-EN
Controls Interface
operator that a diagnostic exists.The second purpose is to
provide navigation to a diagnostic display screen.
Run Inhibit, etc.).The “additional info” icon will present a
subscreen that lists in further detail the subsystem modes.
Diagnostic Screen
A complete listing of diagnostics and codes is included in
the Diagnostic Section.
The Main screen shall be the default screen. After an idle
time of 30 minutes the CH530 shall display the Main screen
with the first data fields.
Manual Override Exists
The remaining items (listed in the following table) will be
viewed by selecting the up/down arrow icons.
An indicator to present the presence of a manual override
will share space with the Alarms enunciator key. While a
manual override exists, the space used for the Alarms key
will be occupied by a “Manual” icon, that will display solid
inverse color similar to the appearance of the Alarms
enunciator. An Alarm will take precedence of the Manual,
until the reset of active alarms, at which point the Manual
indicator would re-appear if such an override exists.
If the Manual indicator is pressed, the Manual Control
Settings screen will be displayed.

Active Chilled Water Subscreen
Password-Protected Settings
The active chilled water setpoint is that setpoint to which
the unit is currently controlling. It is the result of arbitration
between the front panel, BAS, schedule, external, and
auxiliary setpoints (schedule and auxiliary not shown in
the following diagram), which in turn may be subjected to
a form of chilled water reset.
The user can change some settings from the DynaView
display on the chiller. Other settings are passwordprotected. In order to change these setting the password is
314.
Settings Screen
The Settings screen provides a user the ability to adjust
settings necessary to support daily tasks.The layout
provides a list of sub-menus, organized by typical
subsystem.This organization allows each subscreen to be
shorter in length which should improve the user's
navigation.
A sample Settings screen is a list of the subsystems as
shown below.
The chilled water reset status area in the right most column
will display one of the following messages
•

The left column text “Front Panel”, “BAS” or “Schedule”,
“External”, “Auxiliary”, “Chilled Water Reset”, and “Active
Chilled Water Setpoint” will always be present regardless
of installation or enabling those optional items. In the
second column “-----” will be shown if that option is Not
Installed, otherwise the current setpoint from that source
will be shown.
Setpoints that are adjustable from the DynaView (Front
Panel Chilled Water Setpoint, Auxiliary Chilled Water
Setpoint) will provide navigation to their respective
setpoint change screen via a double-arrow to the right of
the setpoint source text.The setpoint change screen will
look identical to the one provided in the Chiller Setpoints
screen.The “Back” button on the setpoint change screen
provides navigation back to the setpoint arbitration
screen.
The “Back” button on the setpoint arbitration screen

Controls Interface
are displayed as spin buttons.The lower half of the screen
is reserved for help screens.
Date/Time Subscreen
All setpoint subscreens will execute the equivalent of a
Cancel key if any display activities cause the subscreen to
be left before a new setpoint is entered. E.g. If Alarms key
is pressed before a new setpoint is entered, new setpoint
will be cancelled.The same applies to any time-outs.
The setpoint screen for setting up the CH530 date is shown
below:The user must select Day, Month, orYear and then
use the up/down arrows to adjust.
Pressing the Auto or Stop keys will not cause a cancel
since the setpoint subscreen is not left on this action.
Enumerated Settings Subscreen
The enumerated setpoint subscreen has no cancel or enter
key. Once a radio key is depressed the item is immediately
set to the new enumeration value.
The setpoint screen for setting up the CH530 time with a 12
hour format is shown below. User must select Hour, or
Minute, then use up/down arrows to adjust. Adjusting
hours will also adjust am/pm.

Binding View
Binding View allows you to assess the status of the
network and all the devices connected as a whole, or the
status of individual devices by using status icons and
function buttons.
Binding View is essentially a table depicting what devices
and options are actually discovered on the network bus
(and their communication status) versus what is required
to support the configuration defined by the feature codes
and categories. Binding View allows you to add, remove,
modify, verify, and reassign devices and options in order
to match the configuration requirements.
Whenever a device is installed, it must be correctly
configured to communicate and to function as intended.
This process is called binding. Some features of Binding
View are intended to serve a second purpose; that is
diagnosing problems with communication among the
devices.
Figure 100. Binding view
Replacing or Adding Devices
If a device is communicating but incorrectly configured, it
might not be necessary to replace it. If the problem with
the device is related to communication, attempt to rebind
it, and if the device becomes correctly configured, it will
then communicate properly.
selected; if it is the correct type, it is bound. If the desired
device cannot be selected or if multiple devices are
accidentally selected, you can close the manual selection
window by clicking on No and repeat the bind function.
If a device that needs to be replaced is still communicating,
it should be unbound. Otherwise, it will be necessary to
rebuild the CH530 network image for Binding View to
discover that it has been removed. An unbound device
stops communicating and allows a new device to be
bound in its place.
It is good practice to turn the power off while detaching
and attaching devices to the CH530 network. Be sure to
keep power on the service tool computer. After power is
restored to the CH530 network, the reconnect function in
BindingView restores communication with the network. If
the service tool computer is turned off, you must restart
TechView and Binding View.
If a device is not communicating, the binding function
displays a window to request manual selection of the
device to be bound. Previously-selected devices are
deselected when the function starts. When manual
selection is confirmed, exactly one device must be

WARNING
Live Electrical Components!
During installation, testing, servicing and
troubleshooting of this product, it may be necessary to
work with live electrical components. Have a qualified
licensed electrician or other individual who has been
properly trained in handling live electrical components
perform these tasks. Failure to follow all electrical
safety precautions when exposed to live electrical
components could result in death or serious injury.
Voltage to the unit must meet the criteria given. Measure
each leg of the supply voltage at the unit's main power
fused-disconnect. If the measured voltage on any leg is not
within specified range, notify the supplier of the power
and correct the situation before operating the unit.
NOTICE:
Equipment Damage!
Inadequate voltage to the unit may cause control
components to malfunction and shorten the life of
relay contact, compressor motors and contactors.
Unit Voltage Imbalance
Excessive voltage imbalance between the phases of a
three-phase system can cause motors to overheat and
eventually fail.The maximum allowable imbalance is 2
percent. Voltage imbalance is determined using the
following calculations:
Unit Voltage Phasing
It is important that proper rotation of the compressors be
established before the unit is started. Proper motor
rotation requires confirmation of the electrical phase
sequence of the power supply.The motor is internally
connected for clockwise rotation with the incoming power
supply phased A, B, C.
Basically, voltages generated in each phase of a polyphase
alternator or circuit are called phase voltages. In a threephase circuit, three sine wave voltages are generated,
differing in phase by 120 electrical degrees.The order in
which the three voltages of a three-phase system succeed
one another is called phase sequence or phase rotation.
This is determined by the direction of rotation of the
alternator. When rotation is clockwise, phase sequence is
usually called “ABC”, when counterclockwise, “CBA”.
This direction may be reversed outside the alternator by
interchanging any two of the line wires. It is this possible
interchange of wiring that makes a phase sequence
indicator necessary if the operator is to quickly determine
the phase rotation of the motor.
Proper compressor motor electrical phasing can be quickly
determined and corrected before starting the unit. Use a
quality instrument, such as the Associated Research
Model 45 Phase Sequence Indicator.
8. Press the Stop key on the Clear Language Display.
9. Open the electrical disconnect or circuit protection
switch that provides line power to the line power
terminal block(s) in the starter panel (or to the unit
mounted disconnect).
10. Connect the phase sequence indicator leads to the line
power terminal block, as follows:
1V x = phase with greatest difference from Vave (without
regard to sign)
For example, if the three measured voltages are 221, 230,
and 227 volts, the average would be:
The percentage of imbalance is then:
This exceeds the maximum allowable (2%) by 0.2 percent.
Phase Sequence Lead
Terminal
Black (Phase A)
L1
Red (Phase B)
L2
Yellow (Phase C)
L3
11. Turn power on by closing the unit supply power fuseddisconnect switch.
12. Read phase sequence on indicator.The “ABC” LED on
the face of phase indicator will glow if phase is “ABC”.
13. If the “CBA” indicator glows instead, open the unit
main power disconnect and switch two line leads on
the line power terminal block(s) (or the unit mounted
disconnect). Reclose the main power disconnect and
recheck the phasing.
NOTICE:
Equipment Damage!
Do not interchange any load leads that are from the
unit contactors or the motor terminals.
14. Reopen unit disconnect and disconnect phase
indicator.

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.
Water System
Flow Rates
NOTICE:
Equipment Damage!
Establish a balanced chilled water flow through the
evaporator. The flow rates should fall between the
minimum and maximum values. Flow rates outside the
recommended range could cause evaporator failure.
Establish a balanced chilled water flow through the
evaporator.The flow rates should fall between the
minimum and maximum values. Chilled water flow rates
below the minimum values will result in laminar flow,
which reduces heat transfer and causes either loss of EXV
control or repeated nuisance, low temperature cutouts.
Flow rates that are too high can cause tube erosion.
Pressure Drop
Measure water pressure drop through the evaporator at
the field-installed pressure taps on the system water
piping. Use the same gauge for each measurement.
Measure flow at the field-installed supply and return.This
will include valves, strainers, and fittings in the pressure
drop readings.
Pressure drop readings should be approximately those
shown in the Pressure Drop Charts in the InstallationMechanical section.

Unit Start-Up Procedures
NOTICE:
Compressor Damage!
Catastrophic damage to the compressor will occur if
the oil line shut off valve or the isolation valves are left
closed on unit start-up.
5. Press the AUTO key. If the chiller control calls for
cooling and all safety interlocks are closed, the unit will
start.The compressor(s) will load and unload in
response to the leaving chilled water temperature.
2. Service the auxiliary equipment according to the startup/maintenance instructions provided by the
respective equipment manufacturers.
3. At this point, all air must be removed from the system
(including each pass). Close the vents in the evaporator
chilled water circuits.
4. Open all valves in evaporator chilled water circuits.
5. If the evaporator was previously drained, vent and fill
the evaporator and chilled water circuit. When all air is
removed from the system (including each pass), install
the vent plugs in the evaporator water boxes.
6. Verify that the chilled water pump runs for at least one
minute after the chiller is commanded to stop (for
normal chilled water systems).
NOTICE:
Equipment Damage!
Note: Once the system has been operating for
approximately 30 minutes and has become
stabilized, complete the remaining start-up
procedures, as follows:
Ensure that the oil sump heaters have been operating
for a minimum of 24 hours before starting. Failure to do
so may result in equipment damage.
7.
Check the evaporator refrigerant pressure and the
condenser refrigerant pressure under Refrigerant
Report on the CH530TechView.
Note: The pressures are referenced to sea level (14.6960
psia).This value is adjustable inTechView.
8. Check the EXV sight glasses after sufficient time has
elapsed to stabilize the chiller.The refrigerant flow past
the sight glasses should be clear. Bubbles in the
refrigerant indicate either low refrigerant charge or
excessive pressure drop in the liquid line or a stuck
open expansion valve. A restriction in the line can
sometimes be identified by a noticeable temperature
differential between the two sides of the restriction.
Frost will often form on the line at this point. Proper
refrigerant charges are shown in General Data tables.
Note: Important! A clear sight glass alone does not mean
that the system is properly charged. Also check
system subcooling, liquid level control and unit
operating pressures.
9. Measure the system subcooling.
10. A shortage of refrigerant is indicated if operating
pressures are low and subcooling is also low. If the
operating pressures, sight glass, superheat and
subcooling readings indicate a refrigerant shortage,
gas-charge refrigerant into each circuit, as required.
With the unit running, add refrigerant liquid charge
slowly thought the suction line service valve until
operating conditions become normal.
Print out a Chiller Service Report fromTechView to file a
start-up claim and to keep for reference with the chiller.

Maintenance
Periodic Maintenance
General
Perform all maintenance procedures and inspection at the
recommended intervals.This will prolong the life of the
chiller and minimize the possibility of malfunctions.
Use an “Operator’s Log” to record the unit’s operating
history.The log serves as a valuable diagnostic tool for
service personnel. By observing trends in operating
conditions, an operator can anticipate and prevent
problem situations before they occur.
If the unit is not operating properly during maintenance
inspections, consult the “Diagnostic and
Troubleshooting” section of this manual.
Weekly Maintenance
NOTICE:
Compressor Damage!
Only add liquid in the suction line when the compressor
is running. Use extreme caution to meter liquid
refrigerant into the suction line slowly. If liquid is added
too rapidly, compressor oil dilution and oil pumpout
could occur. Failure to follow the above could result in
compressor failure or reduced compressor life.
Check the system superheat, subcooling, evaporator
temperature drop (Delta-T), evaporator water flow,
evaporator approach temperature, compressor discharge
superheat, condenser approach and compressor RLA.
Normal operating conditions at AHRI Conditions (55-44°,
95° ambient, .0001ffe) are:
Verify that compressor oil sump heaters are connected
tightly around the compressor.
•
Evaporator Pressure: 120 psig
•
Evaporator Approach: 5-10°F
After the chiller has been operating for approximately 30
minutes and the system has stabilized, check the operating
pressures and temperatures and complete the following
checks:
•
Evaporator Superheat: 12°F
•
Electronic Expansion Valve: 40-50 percent open
•
EvaporatorTemperature Drop (Delta-T): 10°F
Check the evaporator and condenser refrigerant pressures
in the Refrigerant Report menu of the CH530 display.
Pressures are referenced at sea level (14.6960 psia).
•
Compressor DischargeTemperature: 63°F or more
•
Compressor SuctionTemperature: 20°F or more
•
Condensing Pressure: 420-440 psig
•
Condensing ApproachTemperature: 25°F
•
System Subcooling: 15-20°F
•
Compressor RLA: 100 percent
Check the electronic expansion valve sight glasses. (Note:
The electronic expansion valve is commanded closed at
unit shutdown and if the unit is off, there will be no
refrigerant flow through the sight glasses. Only when a
circuit is running will refrigerant flow be present.)The
refrigerant flow through the sight glasses should be clear.
Bubbles in the refrigerant indicate either low refrigerant
charge or excessive pressure drop in the liquid line. A
restriction in the line can sometimes be identified by a
noticeable temperature differential between the two sides
of the restriction. Frost may often form on the liquid line at
this point. Correct refrigerant charges are shown in the
General DataTables.
Important: A clear sight glass alone does not mean that
the system is properly charged. Also check
the system superheat, subcooling and unit
operating pressures.
WARNING
R-410A Refrigerant under High Pressure!
Use ONLY R-410A rated service equipment or
components with these units. For specific handling
concerns with R-410A, please contact your local Trane
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.
CG-SVX17F-EN
If operating pressures and sight glass conditions seem to
indicate a refrigerant shortage, measure the system
superheat and subcooling. Refer to “System Superheat”
and “System Subcooling.”
If operating conditions indicate a refrigerant overcharge,
remove refrigerant at the liquid line service valve. Allow
refrigerant to escape slowly to minimize oil loss. Use a
refrigerant recovery cylinder and do not discharge
refrigerant into the atmosphere.
CAUTION
Refrigerant at Freezing Temperature!
Avoid contact with skin. If working with refrigerant is
necessary, you MUST wear all Personal Protective
Equipment (PPE) including eye protection, safety
gloves, long sleeves, and pants. In case of contact, treat
the injury similar to frostbite. Slowly warm the affected
area with lukewarm water and seek immediate medical
attention. Direct contact with liquid refrigerant could
result in minor to moderate injury.
Inspect the entire system for unusual conditions and
inspect the condenser coils for dirt and debris. If the coils
are dirty, refer to “Coil Cleaning” in this manual.

piping is drained of water, the evaporator immersion
heater must be de-energized. Failure to de-energize the
heater will cause it to burn out.
Clean and repaint any components that show corrosion.
Clean the condenser fans. Check the fan assemblies for
proper clearance in the fan shroud openings and for motor
shaft misalignment or abnormal end-play, vibration and
noise.
Compressor Service Information
Compressor Electrical Connections
It is very important that CSHD compressors used inTrane
Model CGAM chillers are wired correctly for proper
rotation.These compressors will not tolerate reverse
rotation. Verify correct rotation/phasing using a rotation
meter. Proper phasing is clockwise, A-B-C. If wired
incorrectly a CSHD compressor will make excessive noise,
will not pump and will draw about half the normal current.
It will also become very hot if allowed to run for an
extended period.
NOTICE:
Compressor Failure!
Do not “bump” the compressor to check rotation as
incorrect rotation could cause compressor motor failure
in as little as 4 to 5 seconds!
It is also very important that CSHN compressors used in
Trane Model CGAM chillers are wired correctly for proper
rotation. Correct rotation of CSHN compressors is also
clockwise, with A-B-C phasing. Improper rotation of the
CSHN compressors is indicated by a compressor module
trip, noisy operation, no pressure difference on manifold
gauges and low amp draw.
Motor Protection
Internal motor protection is provided on model CSHN
compressors (15, 20, 25 and 30T sizes). LED indicators are
as follows:
•
Green — No Fault
•
Red — Fault
See Table 74, p. 133 for fault diagnostic indications on the
protection module. Manual reset is required at the
module.

UseTrane OilTesting Kit KIT06815 only for testing
lubricating oil in the Model CGAM chiller. Note that the
POE oil used in this product is very hygroscopic and easily
absorbs and retains moisture.The acceptable moisture
content is less than 100 ppm and acceptable acid level is
less than 0.5TAN. Note that refrigerant and moisture is
very difficult to remove from this oil using vacuum. Also
note that once the seal on a container of POE oil is opened,
the oil must be used.
Note: Internal motor protection is not available on CHSD
compressors (10 and 13T sizes).
Oil Level
Oil should also be visible in the sight glass when the
compressor is running.When operating, each compressor
in a tandem or trio set may have a different oil level.
To check compressor oil level, refer to the label near the
compressor sight glass.The compressor(s) must be off.
Wait three minutes.With tandem or triple compressors the
oil level will equalize after shutdown. Compressor oil level
should be clearly visible within the sight glass when the
compressors are off.
Oil Fill, Removal and Capacity
The Model CSHN compressors have an oil charging valve
with a dip tube that goes to the bottom of the compressor.
This can be used to add or remove oil from the
compressor.
Model CSHD compressors have a Schrader valve in the
middle of the compressor which is used to add oil.To
remove oil from these compressors, the system
refrigerant charge must be removed and then the oil can
be removed using a suction style hand pump and tube in
the oil equalizer tube fitting. Oil can also be added to these
compressors through the oil equalizer tube fitting. Care
must be taken to prevent moisture from entering the
system when adding oil.
Compressor Oil Capacity
Important:
Table 75.
Use onlyTrane OIL00080 (1 gallon). Do not
use any other POE oil.

Never reuse oil. Reusing oil could cause equipment
damage.
In the event of a compressor failure, always test the oil with
an acid test kit to determine whether the compressor
failure was mechanical or electrical.This is important
because it dictates correct cleanup procedure.
Compressor Operational Pump Down
The operational pump down is used to manage the
refrigerant charge and prevent liquid slugging into the
compressors, oil dilution and oil starvation.The pump
down will be completed by the last operating compressor
in the refrigerant circuit and occurs during normal
shutdown conditions.The electronic expansion valve will
close.
The operational pump down sequence will end when:
•
Saturated evaporator temperature drops below the
operational pump down set point
•
Compressor pressure differential exceeds 348 psid
(Condensing Pressure - (Evaporator Pressure x 2.9)
•
When the operational pump down time expires (60 x
(100/circuit capacity %))
•
An immediate shutdown diagnostic occurs
•
A pressure transducer fails
Compressor Service Pump Down
Procedure
The Service Pump down procedure is used to store the
Model CGAM refrigerant in the condenser.The condenser
is sized to hold the entire refrigerant charge.
Procedure:
•
Select compressor to use for pump down.
•
All chiller safeties remain in effect.
•
Evaporator water flow must be proven
•
Condenser fans operate normally
•
Manually close refrigerant liquid line service valve
133
Maintenance
Note: The service pumpdown algorithm expects the
liquid line service valve to be closed during service
pumpdown.The EXV will open, allowing the
refrigerant between the liquid line service valve
and EXV to be pumped out.
compressor. If the oil is drained below the level of the oil
level sight glass, it will be below the oil equalizer line level.
Pressurize the low side of the compressor using nitrogen
to help drain the oil. No more than 10 psig of pressure will
be needed.
Service pump down is complete when:
CSHD Compressors
•
Service pump down time expires (60 x (100/circuit
capacity %))
•
Saturated evaporator pressure falls below Low
Pressure Cutout x1.15 for one second
After pump down terminates, the MP automatically puts
circuit into lockout. Pump down can also be terminated by
“Abort Pump down” in service tool, an immediate
shutdown diagnostic occurs or a pressure transducer fails.
CSHD compressors do not have an oil drain valve.
Therefore, before removing the oil equalizer line, the
system refrigerant charge must be recovered before
draining the oil. Use a catch pan to catch the oil when the
compressor oil equalizer line is loosened to ensure that oil
does not spill out of the compressor when the equalizer
line is removed.The torque value for the Rotolock fitting
on CSHD compressors is 64 ft.-lbs., plus or minus 2 ft.-lbs.
Oil Equalizer Line
Tandem Compressor Suction Restrictors
CSHN Compressors
Since most tandem compressor sets use unequal size
compressors, these combinations require the use of a
restrictor in the suction line of one or more compressors
in order to provide correct oil level balance between
compressors when they are operating. See Figure 105,
p. 134 for compressor installation locations for various
unit configurations and Table 76, p. 135 for correct
restrictor applications.
The oil equalizer line is equipped with a Rotolock fitting for
easy removal.Torque values for tightening these fitting is
100 ft.-lbs, plus or minus 10 ft. lbs.
Drain the oil to a level below the oil equalizer tube fitting
before removing the oil equalizer line.This must be done
on both compressors. Use the oil drain valve on the

Model CGAM chillers use POE oil and therefore refrigerant
system open time must be kept to a minimum.The
following procedure is recommended:
Leave a new compressor sealed until it is ready to be
installed in the unit. Maximum system open time is
dependent upon ambient conditions, but do not exceed
one hour open time.
Plug the open refrigerant line to minimize moisture
absorption.
1A & 2B
Do not leave POE oil containers open to the atmosphere.
Always keep them sealed.

Mechanical Compressor Failure
1A & 2B
Replace the failed compressor(s) and change the oil in the
remaining compressor(s) along with the refrigerant
system liquid line filter drier.
Compressor Replacement
Electrical Compressor Failure
If the CGAM chiller suffers a failed compressor, use these
steps for replacement:
Replace the failed compressor and change the oil in the
other compressor(s). Also add a suction filter with cleanup
cores and change the liquid line filter drier. Change filters
and oil until the oil no longer test acidic. See “OilTesting.”
Each compressor has lifting eyes. Both lifting eyes must be
used to lift the failed compressor. See Table 77 for
compressor weights.
Important:
DO NOT LIFT A COMPRESSOR USING A
SINGLE LIFTING EYE.
Use proper lifting techniques, a spreader bar and rigging
as for lifting both compressors simultaneously.

After a mechanical failure of a compressor, it is necessary
to change the oil in the remaining compressor and also
replace the liquid line filter drier. After an electrical failure
of a compressor, it will also be necessary to change the oil
in the remaining compressor, replace the liquid line filter
drier and add a suction filter drier with clean-up cores.

Compressor Motor Megging
Motor megging determines the electrical integrity of the
compressor motor winding insulation. Use a 500 volt
megger. A less than 1 meg-ohm reading is acceptable and
1000 ohms per nameplate volts is required to safely start
the compressor.
Compressor Current Imbalance
Normal current imbalance could be 4 to 15 percent with
balanced voltage due to motor design. Each phase should
register 0.3 to 1.0 ohms and each phase should be within
7 percent of the other two phases. Phase to ground
resistance must be infinity.
Note: Maximum allowable voltage imbalance is 2
percent.
Refrigerant Piping
The compressor suction and discharge lines are copper. In
most instances, piping may be reused. If piping is not
reusable, order the correct service parts. Cut all tubing
with a tubing cutter to prevent copper filings from entering
the system. Cut the tubing in a straight length of pipe after
135
Maintenance
the compressor connection has been unsweated.The line
can then be reinstalled using a slip coupling and brazing.
NOTICE:
Equipment Damage!
The compressor suction line configuration must not be
changed in any way. Changing compressor suction line
configuration will compromise proper oil return to the
compressor(s).
Compressor Electrical Terminal Box
Be sure to protect the terminal box when unbrazing or
brazing compressor refrigerant piping connections
Compressor Oil Sump Heaters
Compressor oil sump heaters must be energized at least
24 hours before starting the CGAM chiller.This is required
to boil refrigerant out of the oil before startup. Ambient
temperature is not a factor and the oil sump heaters must
always be energized prior to startup.
Condenser Maintenance
Condenser Coil Cleaning
WARNING
Hazardous Chemicals!
Coil cleaning agents can be either acidic or highly
alkaline and can burn severely if contact with skin
occurs. Handle chemical carefully and avoid contact
with skin. ALWAYS wear Personal Protective Equipment
(PPE) including goggles or face shield, chemical
resistant gloves, boots, apron or suit as required. For
personal safety refer to the cleaning agent
manufacturer’s Materials Safety Data Sheet and follow
all recommended safe handling practices. Failure to
follow all safety instructions could result in death or
serious injury.
Clean the condenser coils at least once a year or more
frequently if the unit is in a “dirty” environment. A clean
condenser coil will help to maintain chiller operating
efficiency. Follow the detergent manufacturer's
instructions to avoid damaging the condenser coils.
To clean the condenser coils use a soft brush and a sprayer
such as a garden pump type or a high-pressure type. A
high quality detergent such asTrane Coil Cleaner (Part No.
CHM-00255) is recommended.
Refer to RTAC-SVG01B-EN for maintenance and cleaning
procedures.
Note: If detergent mixture is strongly alkaline (pH value
greater than 8.5, an inhibitor must be added).
136
Evaporator Maintenance
NOTICE:
Equipment Damage!
The factory-installed immersion heater must be deenergized if the BPHE evaporator is drained of water for
any reason. Failure to de-energize the immersion
heater will cause it to burn out.
TheTrane Model CGAM liquid chiller uses a brazed plate
heat exchanger (BPHE) evaporator with factory-installed
electronic flow switch (IFM efector) that is positioned in the
evaporator water pipe.The evaporator inlet also includes
a factory-installed immersion heater for freeze protection
and a water strainer that must be kept in place to keep
debris out of the evaporator.
Note: Strainer maintenance is critical to proper operation
and reliability. Any particles larger than 1mm
entering the BPHE evaporator may cause the
evaporator to fail, requiring replacement.
Acceptable BPHE evaporator water flow rate is 1.5 to 3.6
GPM per nominal unit ton capacity.To maintain 54-44 F in/
out chilled water temperatures, the nominal water flow
rate is 2.4 GPM per ton.
Minimum water flow rate must be maintained to avoid
laminar flow, potential evaporator freezing, scaling and
poor temperature control.The microprocessor and
capacity control algorithms are designed to take a 10
percent change in water flow rate per minute while
maintaining a ±2°F (1.1°C) leaving water temperature
control accuracy.The chiller tolerates up to 30 percent per
minute water flow variation as long as the flow is equal to
or greater than minimum flow requirements.
Maximum water flow is 18 feet per second. Flow rates
greater than this will cause excessive erosion.
The BPHE evaporator is difficult to clean should it become
plugged with debris. Indications of a plugged BPHE
evaporator include “wet” suction due to lack of heat
exchange, loss of superheat control, depressed discharge
superheat (<63°F), compressor oil dilution and/or
starvation and premature compressor failure.
Evaporator Replacement
If the CGAM evaporator requires replacement, it is very
important that the new evaporator be replaced correctly
and with the correct refrigerant and water piping
connections.The refrigerant inlet/liquid connection is at
the bottom of the evaporator and the refrigerant outlet/
suction connection is at the top of the evaporator and both
are on the same side. Pay particular attention to
evaporators with dual circuits. Avoid cross-circuiting
when installing the new evaporator.
CG-SVX17F-EN
Maintenance
Water Strainer Maintenance
Factory-installed water strainer is aY-type design.The
stainer is equipped with a blow-down valve.The strainer
is a 16 mesh (approximately 1 mm) material.
Figure 106. Water strainer - Y type
Accessing Pump Package Components for
Servicing
To access pump package components for servicing, unlock
the access panel door, and remove. Remove remaining top
panel(s). See Table 107 for location of bleed, drain and
flush valves.
Figure 107. Pump package valve location
For maximum efficiency, a differential pressure gauge
installed across the inlet and outlet will indicate pressure
loss due to clogging and may be used as a guide to
determine when cleaning is required.The taps for the
pressure gauges are included as standard from the factory.
Normally when differential pressure reaches 5-10psi, the
screen must be cleaned.The strainer is equipped with a
blow-down valve on the cover plate.To clean open and

Description/Troubleshooting
A Valid Configuration is Present
A valid configuration is present in the MP’s nonvolatile memory. The configuration is a set of variables and settings
that define the physical makeup of this particular chiller. These include: number/airflow,/and type of fans, number/
and size of compressors, special features, characteristics, and control options.
// Temporary display of this screen is part of the normal power up sequence.
App Present. Running

Selftest Passed
An application has been detected in the Main Processor’s nonvolatile memory and the boot code is proceeding to run
a check on its entirety. 8 seconds later, the boot code had completed and passed the (CRC) test.
// Temporary display of this screen is part of the normal power up sequence.
App Present. Running Selftest
Err3: CRC Failure
An application has been detected in Main Processor’s nonvolatile memory and the boot code is proceeding to run a
check on its entirety. A few seconds later, the boot code had completed but failed the (CRC) test.
//Connect a TechView Service Tool to the MP’s serial port, provide chiller model number (configuration information)
and download the configuration if prompted by TechView. Then proceed to download the most recent RTAC
application or specific version as recommended by Technical Service. Note that this error display may also occur
during the programming process, if the MP never had a valid application any time prior to the download. If problem
persists, replace MP.
Boot Software Part Numbers:
LS Flash --> 6200-0318-XX
MS Flash --> 6200-0319-XX
The “boot code” is the portion of the code that is resident in all MPs regardless of what application code (if any) is
loaded. Its main function is to run power up tests and provide a means for downloading application code via the MP’s
serial connection. The Part numbers for the code are displayed in the lower left hand corner of the DynaView during
the early portion of the power up sequence and during special programming and converter modes. See below. For
the EasyView, the extension of the boot code part number is displayed for approximately 3 immediately following
power up.
// This is normal, but you should provide this information when contacting Technical Service about power up problems.
Converter Mode
A command was received from the Service Tool (Tech View) to stop the running application and run in the “converter
mode”. In this mode the MP acts as a simple gateway and allows the TechView service computer to talk to all the
LLIDS on the IPC3 bus.
Err2: RAM Addr Test #1 Failure There were RAM errors detected in RAM Address Test #1. //Recycle power, if error persists, replace MP.
Err2: RAM Addr Test #2 Failure There were RAM errors detected in RAM Address Test #2. //Recycle power, if the error persists, replace MP.
Err2: RAM Pattern 1 Failure
There were RAM errors detected in RAM Test Pattern #1. // Recycle power, if the error persists, replace MP.
Err2: RAM Pattern 2 Failure
There were RAM errors detected in RAM Test Pattern #2. //Recycle power, if the error persists, replace MP.
Err4: UnHandled Interrupt
Restart Timer:
[3 sec countdown timer]
An unhandled interrupt has occurred while running the application code. This event will normally cause a safe
shutdown of the entire chiller. Once the countdown timer reaches 0, the processor will reset, clear diagnostics, and
attempt to restart the application and allow a normal restart of chiller as appropriate.
// This condition might occur due to a severe electro-magnetic transient such as can be caused by a near lightening
strike. Such events should be rare or isolated and if no damage results to the CH.530 control system, the Chiller
will experience a shutdown and restart. If this occurs more persistently it may be due to an MP hardware problem.
Try replacing the MP. If replacement of the MP proves ineffective, the problem may be a result of extremely high
radiated or conducted EMI. Contact Technical Service.
If this screen occurs immediately after a software download, attempt to reload both the configuration and the
application. Failing this, contact Technical Service.
Err5: Operating System Error
Restart Timer:
[3 sec countdown timer]
An Operating System error has occurred while running the application code. This event will normally cause a safe
shutdown of the entire chiller. Once the countdown timer reaches 0, the processor will reset, clear diagnostics, and
attempt to restart the application and allow a normal restart of chiller as appropriate.
// See Err 4 above
Err6: Watch Dog Timer Error
Restart Timer:
[3 sec countdown timer]
A Watch Dog Timer Error has occurred while running the application code. This event will normally cause a safe
shutdown of the entire chiller. Once the countdown timer reaches 0, the processor will reset, clear diagnostics, and
attempt to restart the application allowing a normal restart of chiller as appropriate.
Err7: Unknown Error
Restart Timer:
[3 sec countdown timer]
An unknown Error has occurred while running the application code. This event will normally cause a safe shutdown
of the entire chiller. Once the countdown timer reaches 0, the processor will reset, clear diagnostics, and attempt to
restart the application allowing a normal restart of chiller as appropriate
Err8: Held in Boot by User Key
A touch was detected during boot indicating the user wanted to stay in boot mode. This mode can be used to recover
Press
from a fatal software error in the application code. Cycle power on the MP to clear this error if it was unintentional.
[3 sec countdown timer]
MP Application Memory CRC
Error
App software inside the MP failed its own checksum test. Possible causes: application software in the MP is not
complete – software download to the MP was not completed successfully - or MP hardware problem. Note: User should
attempt to reprogram the MP if this diagnostic occurs.
MP: Invalid Configuration
MP has an invalid configuration based on the current software installed
No Application Present
Please Load Application...
No Main Processor Application is present – There are no RAM Test Errors.
// Connect a TechView Service Tool to the MP’s serial port, provide chiller model number (configuration information)
and download the configuration if prompted by TechView. Then proceed to download the most recent application or
specific version as recommended by Technical Service.
Programming Mode
A command was received by the MP from the Tech View Service Tool and the MP is in the process of first erasing and
then writing the program code to its internal Flash (nonvolatile) Memory. Note that if the MP never had a prior
application already in memory, the error code “Err3”will be displayed instead of this, during the programming
download process.
