AFDR-SVN001D-EN
Page 2
Introduction
Read this manual thoroughly before operating or servicing
this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as
required. Your personal safety and the proper operation of
this machine depend upon the strict observance of these
precautions.
The three types of advisories are defined as follows:
WARNING
CAUTIONs
NOTICE
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 handli ng of
all refrigerants-including industry replacements for CFCs
and HCFCs such as saturated or unsaturated HFCs and
HCFCs.
Important Responsible Refrigerant
Practices
Trane believes that responsible refrigerant practices are
important to the environment, our customers, and the air
conditioning industry. All technicians who handle
refrigerants must be certified according to local rules. For
the USA, the Federal Clean Air Act (Section 608) sets forth
the requirements for handling, reclaiming, recovering and
recycling of certain refrigerants and the equipment that is
used in these service procedures. In addition, some states
or municipalities may have additional requirements that
must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.
Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.
Indicates a potentially hazardous
situation which, if not avoided, could

unsafe practices.
Indicates a situation that could result in
equipment or property-damage only
accidents.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury. All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes.
WARNING
Personal Protective Equipment (PPE)
Required!
Failure to wear proper PPE for the job being undertaken
could result in death or serious injury. Technicians, in
order to protect themselves from potential electrical,
mechanical, and chemical hazards, MUST follow
precautions in this manual and on the tags, stickers,

and Local Electrical Codes!
Failure to follow all applicable codes could result in an
arc flash event, electrocution, explosion, or fire, which
could result in death or serious injury. Users MUST
conform to all applicable national, state, and local
electrical codes during the electrical installation and
servicing of this product.
NOTICE
Excessive Cable Lengths Between AFDR
Drive and Compressor Motor!
Trane assumes no responsibility for equipment damage
caused by use of improper cable lengths. The variable
frequency drive industry recommends that the length
of the electrical cables connecting a drive unit to a
motor should be kept to less than 250 feet to protect
the motor from reflected voltage waves that can cause
the motor to fail. Cable lengths that exceed 250 feet
between the drive and the motor create the potential
for damage to occur to the motor windings and/or
insulation.

General Information
The step-by-step instructions outlined in this manual
describe the procedures required to successfully install an
AFDR retrofit air-cooled Adaptive Frequency Drive™
package in place of an existing starter on a Trane RTHD
helical rotary liquid chillers. This only applies to chillers
having a Tracer AdaptiView™ controller. If the RTHD chiller
has a CH530, it must be replaced with the Tracer
AdaptiView™ RTHD rotary chiller display upgrade kit
(RCDA; sold separately).
The AFDR can be ordered as a close floor mount, remote
floor mount, or remote wall mount. Voltage options
include 460/480 volts, 380/400 volts, and 575/600 volts.
D-Frame size AFDH drive packages can be ordered in a
unit-mounted, stand-mounted, or remote floor-mounted
cabinet configuration. The AFDR units can be equipped
with a drive having a maximum rating of 190 amps,
240 amps, 302 amps, 361 amps, 443 amps, or 535 amps
for 460V/480V, and 131 amps, 155 amps, 193 amps,
242 amps, 344 amps, or 400 amps for 575V/600V.
Other Literature Required Before Ordering
or Installing an AFDR Retrofit
This manual must be used in conjunction with the
following publications:
For service purposes, Trane model
AFDR air-cooled drive upgrade
packages are assigned a multiple
character alphanumeric model
number that precisely identifies each
unit.
An explanation of the identification
code that appears on the unit
nameplate is shown below. Use of
the service model number will
enable the owner/operator, installing
contractors, and service technicians
to define the operation, components,
and options for any specific unit.
Refer to the model number printed
on the nameplate when ordering
replacement parts or requesting
service.
Important: The location of the AFDR is important if
proper performance and normal operating
life is to be expected. Therefore, unless
designed for special environments, the
controller should be installed in an area
where the following conditions exist.
•Verify that NEMA 1 enclosure is installed where it can
be kept clean and dry, away from oil, coolants, or other
airborne contaminants. The enclosure must be
installed in a non-corrosive location.
•The area chosen should allow the space required for
proper air flow. Adequate clearance for air circulation
around the enclosure is a 6 in. (15.25 cm) minimum
clearance required wherever vents are located in the
cabinet.
•The area chosen should allow for service clearance in
front of the enclosure. Three feet (0.91 m) is
recommended for door swing and working space;
more space may be required by local building codes or
for service equipment, such as hoists used for drive
replacement. Because codes and equipment may vary,
determine the amount of space required for each
specific installation.
•Do not install the drive over 3300 ft (1000 m) above sea
level without derating output power. For every 300 ft
(91.4 m) over 3300 ft (1000 m) above sea level, derate
the output current 1 percent.
•Line frequency is 60 Hz.
•Line voltage options are 460, 480, 575 or 600 volts;
variation must be within +
•Verify that the drive location will meet the
environmental conditions specified in
10 percent.

A nameplate is included for each AFDR air-cooled drive
unit. Always provide the model number and serial number
that is printed on this nameplate when making warranty
inquiries, ordering parts, or ordering literature for the unit.
Figure 1.AFDR nameplate example
The AFDR nameplate label (Trane Motor Controller
Nameplate) is customized for each AFDR order and is
specific to each RTHD unit. The Trane Motor Controller
Nameplate and must be installed on the Trane TR200
drive. Remove the adhesive backing and locate the label
on the TR200 drive next to the AFD nameplate. The
existing nameplate located on the RTHD chiller panel must
also remain in place. When programming the current limit
value into Tracer™ TU, always use the Trane Motor
Controller Nameplate that is place on the TR200 drive.
AFDR Controls
If there is an existing CH530 controller, the Tracer
AdaptiView™ RTHD rotary chiller display upgrade
kit (RCDA) must be installed. Follow the installation
If the RTHD to be retrofitted to AFD already has a UC800
Tracer AdaptiView controller, that can be reused.
Important: Regardless if it is new or existing, the UC800
must have a software upgrade to support
the AFDR. For more information, refer to
“UC800 Software Installation and
Configuration,” p. 52
Installation
.
Output Current
The output current listed on the Trane motor controller
nameplate on the AFD (see
current that the drive will be required to provide when the
compressor motor is operated at a frequency that results
in reduced motor voltage. The output current is used by
the RTHD chiller controller for correctly limiting chiller
capacity under these conditions. The output current listed
on the Trane motor controller nameplate on the AFD
should NOT be confused with the chiller nameplate Rated
Load Amps (RLA), which are unchanged by the retrofit.
The RLA is now to be considered the input current to the
chiller.

Required Parts—NOT Supplied
•Modbus™ cable (for remote or wall mount)
Because the distance varies with each application,
Modbus™ connectors are not provided for remote and
wall mount kits. The Modbus™ connection requires a
unique connection type for the UC800 and a unique
connection type for the AFD (listed above). The Global
Connector Extension is used for spanning the rest of the
wire distance between the panel and the AFD. Maximum
length 250 feet.
NOTICE
Excessive Cable Lengths Between AFDR
Drive and Compressor Motor!
Trane assumes no responsibility for equipment damage
caused by use of improper cable lengths. The variable
frequency drive industry recommends that the length
of the electrical cables connecting a drive unit to a
motor should be kept to less than 250 feet to protect
the motor from reflected voltage waves that can cause
the motor to fail. Cable lengths that exceed 250 feet
between the drive and the motor create the potential
for damage to occur to the motor windings and/or
insulation.

Oil and Refrigerant Removal
WARNING
Refrigerant under High Pressure!
Failure to follow instructions below could result in an
explosion which could result in death or serious injury
or equipment damage. System contains oil and
refrigerant under high pressure. Recover refrigerant to
relieve pressure before opening the system. See unit
nameplate for refrigerant type. Do not use nonapproved refrigerants, refrigerant substitutes, or
refrigerant additives.
RTHD units with an AFD require a lower viscosity oil to
operate. With an AFD installed on an RTHD chiller, a
minimum nominal oil viscosity of 110 cSt must be
attained. The existing oil (OIL00048) must be removed
from the RTHD unit and replaced with the new oil
(OIL00315/317) (not included) before operating with an
AFD.
To attain the minimum nominal viscosity, at least
90 percent of the existing oil must be removed from
the chiller; refer to chiller nameplate for original
chiller oil charge. Both the oil filter (FLR01683) and cold
filter (FLR01682) must be replaced and are not included
with this upgrade. It is acceptable to change the oil to the
new oil and still run the RTHD unit without the AFD
installed, if it is more convenient to change to the new oil
and operate the RTHD unit for a period of time before the
AFD can be installed.
See
Figure 26, p. 30 in the following steps to reference
valves locations by number.
Notes:
•Follow all manufacturer's recommendations for
recovery equipment usage.
•Keep all oil removed to measure the total amount of oil
removed from the unit.
•The replacement oil (OIL00315/317) and oil filters are
NOT supplied with this upgrade and must be
purchased separately.
1. Connect hoses from recovery unit to chiller, configured
to recover liquid refrigerant (Push-Pull/Mechanical
Pump). Use 5/8” access value on the evaporator or
condenser (number 25 or number 19).
2. Open valves on chiller and start recovery machine.
Complete the transfer of the liquid from the unit to the
cylinder(s).
3. Once all of the liquid has been recovered, reconfigure
the recovery unit for vapor by moving hose from liquid
port to a vapor port to separate the refrigerant from the
Solest 68 (OIL00048).
4. Recover vapor down to 0 psi.
5. Weigh and record the total amount of refrigerant
removed from chiller.
6. Pressurize the evaporator to 2 psi nitrogen at the valve
(number 30).
7. Pressurize the condenser to 2 psi nitrogen at the valve
(number 13).
8. Drain the oil at the oil sump valve (number 7).
9. Energize the oil solenoid valve (number 40).
10. Pull the plugs under the gear housing on the
compressor (three plugs total) and drain the oil.
Figure 25.
11. Pull the plugs under the motor housing on the
compressor (one or two plugs total) and drain the oil.
28 AFDR-SVN001D-EN
Page 29
Pre-Installation
Note: C-, D-, and E-frame compressors have two
plugs; B-frame compressors have one plug.
12. De-energize the oil solenoid valve.
13. Change the oil filter (number 38; not insulated).
Change the cold oil filter (number 48; insulation will
need to be removed).
14. Perform pressure test.
15. Evacuate the unit to a minimum of 500 microns and
perform a rise test.
16. Add the total oil charge according to
Table 6. Adding an
AFD to the RTHD chiller requires more oil than the
original factory configuration.
a. Add enough Solest 120 (OIL00315/317) to the oil
filter (number 7) to fill the filter.
b. Add remaining total Solest 120 (OIL00315/317)
charge at the oil sump (number 7).
Important: Be sure to either run the evaporator and
condenser pumps when adding refrigerant
to prevent freezing or verify that the water
has been drained to prevent freezing tubes.
17. Compare amount of refrigerant removed in previous
step to the nameplate charge. Charge appropriately at
evaporator (number 25) according to the table for units
with an AFD. Add refrigerant as needed to ensure the
unit is fully charged.
Important: Oil charges shown in Table 6 are for new
RTHD chillers with AFD; when retrofitting
existing RTHD chillers with AFD, increase oil
charge shown in Table 6 proportionately
based on how much oil was extracted
during oil removal process.
18. At the oil sump, apply provided oil label sticker listing
the new oil, OIL00315.

Recommended Rigging and
Lifting Procedures for AFDR Drive
Units
WARNING
Heavy Objects!
Failure to follow instructions below or properly lift unit
could result in unit dropping and possibly crushing
operator/technician which could result in death or
serious injury, and equipment or property-only damage.
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.
WARNING
Improper Unit Lift!
Failure to properly lift unit could result in unit dropping
and possibly crushing operator/technician which could
result in death or serious injury, and equipment or
property-only damage. An AFDR cabinet assembly is
top heavy. 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.
Unit Lifting Points—Preferred Lifting
Method
•The preferred method for lifting an AFDR drive unit to
position it for installation is to use an identical
individual hoisting device at each lift point.
Figure 57. Preferred lifting method using two identical
individual hoists
Unit Lifting Points—Alternative Lifting
Method
•If it is only possible to use a single hoisting device to lift
an AFDR drive unit to position it for installation, a
spreader bar should be used to allow adjusting the
rigging as necessary to balance the unit around its
center-of-gravity to ensure full control of the unit
during lifting.

NOTICE
Compressor Damage!
Before connecting power wire to the motor terminals,
with the motor terminal jumpers removed, verify
proper phasing between the drive and motor terminals
with an ohmmeter for all connections. Improper
phasing occurs between the drive and motor terminals
can cause compressor damage.
2. After Tracer TU is launched, the Startup Task Panel
dialog box appears; refer to
Figure 78. Select Direct
Connection and then click Connect button.
Important: Tracer TU version 9.0.322 is required. If that
version or newer is not already installed,
refer to
“Pre-Installation,” p. 18 for details
on how to obtain and upgrade Tracer TU.
UC800 Software Installation and
Configuration
Note: The software upgrade process requires that the
UC800 ether have no application code already
installed, or if an application is existing, that the
controller be in the Stop mode and that the
compressor and the pumps have been shut off. TU
will enforce this requirement with pop-up
messages at the appropriate step in the process,
but it is best to Stop the chiller before the software
upgrade process begins.

nameplate's Output Current; refer to
and
Figure 90.
Figure 89
Notes:
•The Compressor Rated Load Amps need to be
increased over the previously set RLA current as this
value now refers to the currents occurring between the
drive and the motor, which are slightly higher (at full
load rating point) than for a Wye Delta Starter Type.
•The new Compressor Rated Load Amps are used to
“calibrate” the UC800 controller so it can provide a
current limit function at the correct current level. Motor
protection becomes a function of the AFD and its
settings.
•Current flowing into the unit (into the drive) remains at
or below the previous RLA stamped on the original
shipped RTHD nameplate; thus, there is no need to
increase the upstream branch wiring or circuit
protection.

this time, all new LLIDs must be bound. If there is a mix
of existing and new LLIDs, Trane recommends that all
existing LLIDs be unbound; then, rebind existing LLIDs
and bind new LLIDs.
Important: For more information about binding LLIDs,
Note: Because the AFDR does not use the IPC link, it
will not appear on the binding list. Instead, the
AFDR uses the new Modbus™ Master
Communication port (labeled IMC on the
UC800). Drive parameters must be set
independently and manually. For more
information about AFDR TR200 setup, refer to
“Drive Settings,” p. 60.
11. After all LLIDs have been properly bound (refer to
Figure 94), navigate to Tracer TU’s Setpoints tab to
check and adjust settings accordingly. Refer to the
existing Chiller Service Report for customer settings
such as Low Refrigerant Temperature Cutout,
Low Water Temperature Cutout, Chilled Water

Troubleshooting
The drive displays three types of faults:
•Warning
A warning or alarm is signaled by the LEDs on the front
of the AFD by a code on the LCP.
A warning indicates a condition that may require
attention or a trend that may eventually require
attention, and will remain active until the cause is no
longer present. Under some circumstances, motor
operation may continue.
•Trip
A trip is the action when an alarm has appeared. The
trip removes power to the motor and, after the
condition has been cleared, can be reset by pressing
the Reset button. The event that caused an alarm
cannot damage the AFD or cause a dangerous
condition.
After its cause has been rectified, an alarm must be
reset to restart operation.
•Trip Lock
A trip lock is an action when an alarm occurs that may
cause damage to the AFD or equipment. Power is
removed from the motor, and a trip lock can only be
reset after the condition is cleared by cycling power.
Once the problem has been rectified, only the alarm
continues flashing until the AFD is reset.
d. In the Binding view of the Tracer TU service tool,
verify there is a green face indicating that the Starter
LLID is bound.
e. Record any drive diagnostics found.
2. Collect Chiller Information.
a. Note the following chiller information:
• Operating mode and any sub-mode (i.e., 100%
or 75% load etc.)
• Number of chiller starts, and hours of operation.
• Time since last diagnostic shutdown (<1 minute,
<1 hour, >1 hour, etc.)
b. What was the chiller state at the time of the failure?
(Chiller starting? Running low load? Running full
load? etc.)
c. Record the chiller’s sales order and serial numbers,
and the drive’s serial and model numbers.
3. Troubleshooting
a. Measure and record the DC bus (via the Local
Control Panel [LCP]).
b. Check ALL wiring (tightness, ribbon cables fully
seated, proper phasing, etc.)
c. Refer to the Danfoss manuals for further
troubleshooting information.
WARNING
Hazardous Voltage w/Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives
or other energy storing components provided by Trane
or others, refer to the appropriate manufacturer’s
literature for allowable waiting periods for discharge of
capacitors. Verify with an appropriate voltmeter that all
capacitors have discharged.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06*-EN.

WARNING
Hazardous Voltage with Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives
or other energy storing components provided by Trane
or others, refer to the appropriate manufacturer’s
literature for allowable waiting periods for discharge of
capacitors. Verify with an appropriate voltmeter that all
capacitors have discharged.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06*-EN.
1. Ensure the door interlocks are present and working.
2. Verify the safety ground connections to the door
panels are securely connected.
3. Inspect power wire cables and devices to assure no
abrasion is occurring from vibrations against chassis
of cabinets, or other edges.
4. Ensure the drive interior and exterior is clear of any
dust or debris. Fans, circuit boards, vents, etc. must be
clean. Only use a vacuum for cleaning. Do NOT use
compressed air.
5. Inspect the interior of the drive for any signs of
moisture entry or leakage.
6. Visually inspect all drive components and wiring. Look
for signs of heat or failure (look for swelled or leaking
capacitors, discolored reactors or inductors, broken
pre-charge resistors, smoke or arc trails on MOVs and
capacitors, etc.)
7. Closely inspect the motor terminal board for any signs
of leakage, arcing, etc.
8. Check ALL cable/lug/terminal connections inside the
drive enclosure. Ensure all are clean and tight, and not
rubbing against each other anywhere.

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.
1. Verify the drive cabinet cooling fans are operati ng. This
should be done from outside the enclosure, by looking
into the cabinet at door and cabinet vents, to avoid
electrical hazards.
Note: The power module fan comes on with power.
Other fans cycle with drive operation.
2. Check historic fault codes using LCP connected to the
AFD.
3. Check configuration settings and confirm all proper
settings are still present in the controls.
4. Review the diagnostic history.
5. Make Chiller Service report to document all setpoints.
6. Check the UC800 alarm histories for any indications of
operational problems.
Do this every 1–12 months depending on
operating environment.
To properly diagnose service issues for Adaptive
Frequency Drives for centrifugal chillers equipped with
AFDR starters, all UC800 chillers will be equipped with the
LCP as standard on the drive power module. This is for
service only and NEVER for machine operation.
