1.1 SAFETY PRECAUTIONS

WARNING
!
SAFETY CONSIDERATIONS: Installation and servicing of refrigeration equipment can be
hazardous due to system pressures, rotating elements and electrical components. Only
trained & qualified service personnel should install, repair or service refrigeration equipment.
When working on refrigeration equipment, observe precautions in all literature including this
manual, the equipment tags and labels attached to the unit, and other safety precautions that
may apply. Follow safe work practices and utilize the appropriate protective equipment at all
times.

Your Carrier Transicold refrigeration unit has been designed with the safety of the operator in mind. During normal
operation, all moving parts are fully enclosed to help prevent injury. During all pre-trip inspections, daily inspec-
tions, and problem troubleshooting, you may be exposed to moving parts. Please stay clear of all moving parts
when the unit is in operation and when the START/RUN-OFF switch (SROS) is in the START/RUN position.

NOTI
CE
Electronic modules MUST be handled with care to prevent accidental damage or degradation
from electrical static discharge (ESD), contamination or abuse. Before touching a module,
touch your body and/or conductive tool being used to the frame to discharge ESD safely. All
electronics should be handled carefully and only held by edges of any exposed board. Care
should be taken when inserting/extracting connectors and components to avoid exerting
excessive stress on the board which could fracture small components nearby, resulting in
future failure of circuit.

NOTI
CE
Under no circumstances should a technician electrically probe the modules at any point,
other than the connector terminals where the harness attaches. Module components operate
at different voltage levels and at extremely low current levels. Improper use of voltmeters,
jumper wires, continuity testers, etc. could permanently damage the module.

Automatic Start-Stop This unit is equipped with Auto-Start in Start-Stop and Continuous Operation. The unit may
start at any time. A buzzer will sound for 5 seconds before the unit is started. When performing any check of the
refrigeration unit (e.g., visually checking the belt, oil, or coolant), place unit in Inspect Mode, unplug the high
voltage connector, and disconnect the starter solenoid connector. Engine Coolant The engine is equipped with a
pressurized cooling system including a pressurized coolant bottle. Under normal operating conditions, the coolant
in the engine and radiator is under high pressure and is very hot. Contact with hot coolant can cause severe
burns. Do not remove the cap from a hot coolant system. If the cap must be removed, cover it with a rag and
remove very slowly in order to release the pressure without spray. Refrigerants The refrigerant contained in the
refrigeration system of this unit can cause frostbite, severe burns, or blindness when in direct contact with the skin
or eyes. For this reason (and because of legislation regarding the handling of refrigerants) we recommend that
you contact your nearest Carrier Transicold authorized repair facility whenever service of the refrigerant system is
required. Battery This unit may be equipped with a lead-acid type battery. The battery normally vents small
amounts of flammable hydrogen gas. Do not smoke when checking the battery. A battery explosion can cause
serious physical harm and/ or blindness.

1–3 62-11640

WARNING
!
Never use air or gases containing oxygen for leak testing or operating refrigerant
compressors. Pressurized mixtures of air or gases containing oxygen can lead to explosion.

WARNING
!
Disconnect batteries before doing any electrical welding on unit or chassis to which unit is
attached (trailer, container, rail car, metal building, etc).

WARNING
!
Inspect battery cables for signs of wear, abrasion or damage at every pre-trip inspection and
replace if necessary. Also check battery cable routing to ensure that clamps are secure and
that cables are not pinched or chafing against any components.

WARNING
!
Use the required protective eye wear and clothing when working with solvents.

WARNING
!
Only a refrigerant cylinder containing R404A should be connected to this refrigeration unit in
order to pressurize the system. However, dry nitrogen may be used to increase pressure. Any
other gas or vapor will contaminate the system and require additional removal and
evacuation.

WARNING
!
Do not use a nitrogen cylinder without a pressure regulator. Cylinder pressure is
approximately 2350 psig (159.9 bar). Do not use oxygen in or near a refrigerant system as an
explosion may occur. (See Figure 8.30)

WARNING
!
Before removal of the compressor, relieve the internal pressure by very carefully loosening
the couplings to break the seal.

WARNING
!

solutions to enter the generator.
62-11640 1–4

WARNING
!
Generators of this type should not be “flashed.” Operation with external voltage source or
momentary shorting of leads will damage the generator and may cause injury.

WARNING
!
A mica shim (Carrier Transicold P/N 54−00630−25) must be installed before removal of the generator.
The generator is to be removed as one piece, with the shim in place. DO NOT attempt to remove the

rotor from the stator. WARNING !

Never disassemble the generator rotor from the stator due to the high force required to do so
and the high magnetic field that will result. The field present when the rotor is disassembled
from the stator may interfere with cardiac implants such as pacemakers and defibrillators.

CAUTION
!
Service Mode MUST be used whenever removing refrigerant charge, refrigerant leak
checking or evacuating.

CAUTION
!
Before connecting a megohmmeter, place the Main Power switch in the OFF position.
Discon- nect the high voltage source, lockout/ tagout the receptacle and disconnect the
negative bat- tery connection. Isolate the microprocessor by disconnecting all connectors
and wires going to it. Observe National Electric Manufacturer’s Association (NEMA) rules and
test equipment manufacturers instructions.

canceled, Technician Mode will be available for 60 minutes after the last key press without
requiring a code, even after placing the SROS in the OFF and then back in the RUN/ STOP
position.

NOTI
CE
Ensure that the clock you are using is accurate. Also, some customers are located in different
time zones from the repair location. If you know the owners desired location time, enter that
time. If you don’t, enter the current time at your location.
 NOTI
CE
DO NOT leave the air intake circuit energized for the full 5 minutes if full amperage is shown,
as the intake air heater element life will be greatly shortened.

NOTI
CE
Unit uses R404A and POE oil. The use of inert gas brazing procedures is mandatory for all
Carrier Transicold refrigeration units; otherwise compressor failure will occur. For more
information Refer to Technical Procedure 98-50553-00 Inert Gas Brazing.

NOTI
CE
Running the engine for an extended period of time with the manual plunger up can cause a
priming pump failure.

NOTI
CE
Torque fuel level sensor mounting screws to 15 to 18 inch/lbs (1.7 to 2.0 Nm). DO NOT over
tighten, as little as 20 inch/pounds (2.3 Nm) will damage the sensor.

NOTI

possible. If the filters are not primed, the engine may operate for a period with no oil supplied
to the bearings.
62-11640 1–6

NOTI
CE
NEVER POUR COLD WATER INTO A HOT ENGINE, however hot water can always be added to
a cold engine.

NOTI
CE
Use only ethylene glycol anti-freeze (with inhibitors) in system as glycol by itself will damage
the cooling system. Always add pre-mixed 50/50 anti-freeze and water to radiator / engine.
Never exceed more than a 60% concentration of anti-freeze. Use a low silicate anti-freeze
meeting GM specifications GM 6038M for standard life coolant or use Texaco Havoline
extended life coolant or any other extended life coolant which is Dexcool approved and has 5/

150 (5 years / 150,000 miles) on the label. NOTICE

The scroll compressor achieves low suction pressure very quickly. Do not use the
compressor to evacuate the system below 0 psig. Never operate the compressor with the
suction or discharge service valves closed (frontseated). Internal damage will result from
operating the compressor in a deep vacuum.

NOTI
CE
When a module is replaced, software should be upgraded before switching the unit on. This
will ensure software compatibility of all modules.

NOTI
CE
Do not vapor charge R404A. Only liquid charging through the liquid line service valve is
acceptable.

NOTI
CE
Do not bend the copper tubing on the condenser coil when installing the new condenser.

ensure any two way communication is disabled in accordance with the manufacturer’s
instruction, ensure the START/ RUN-OFF switch is in OFF position and, whenever practical,
disconnect the high voltage source, lockout/tagout the receptacle and disconnect the
negative battery connection.

This manual contains operating data, electrical data and service instructions for the refrigeration unit listed in
Table 2–1. Additional support manuals are listed in Table 2–2. The unit model/serial number plate is located
inside the unit on the frame as shown in Figure 2.1.

2.2 GENERAL DESCRIPTION

Units described in this manual are hybrid/electric, fully charged, pre-wired, refrigeration/heating “nosemount”
units. The units are used on insulated refrigerated compartments to maintain cargo temperatures within very close
limits. Electrical power is supplied to the unit from an external source, at the power supply receptacle (PSR), or by
the AC generator which is driven by the engine. The generator provides nominal 480V/3ph/60Hz power when the
engine is in high speed and nominal 350V/3ph/45Hz power in low speed. The APX Control System includes a
manual switch, control modules, fuses, and associated wiring. High voltage contactors, fuses and the contactor
control boards are located in the control box while contactors for the optional standby electric power are located in
the standby box (see Figure 2.4). The unit may be equipped with an optional remote light bar which mounts
separately on the front outside corner of the refrigerated compartment. Temperature control is provided by the
Carrier Transicold APX control system (Refer to Section 2.5). Once the desired temperature is set, the unit will
operate automatically to maintain the desired temperature within very close limits. When in Engine Operation, the
APX Control System automatically selects high / low speed cooling or high / low speed heating as necessary to
maintain the desired temperature within the refrigerated compartment. Standard equipment includes an auto start-
stop feature. This feature provides automatic cycling of the diesel engine, which in turn offers an energy efficient
alternative to continuous operation of the engine with control of tem- perature by alternate cooling and heating of
the supply air (evaporator outlet air). The unit may be equipped with AutoFresh Air Exchange which controls air
quality and humidity for fresh produce. The unit is described as having three major sections:
• The condensing section (Figure 2.1 & Figure 2.2), which includes the engine generator drive package
• The evaporator section (Figure 2.3)
• The control system (Figure 2.2)

2.3 CONDENSING SECTION

The condensing section (see Figure 2.1 & Figure 2.2) consists of an engine-generator drive package, compres-
sor, condenser fans, condenser, radiator, economizer, refrigerant controls, defrost air switch, piping, wiring, and
associated components. The condensing section may also be equipped with an AutoFresh Air Exchange. The
engine-generator drive package (see Figure 2.2) includes the engine, generator, air cleaner, muffler, coolant
system, fuel system, engine oil filter system and engine sensors.

2.3.1 Engine The engine is a four cylinder diesel which gives excellent fuel economy. The engine cooling system
consists of the radiator (which is mounted with the condenser coil) and coolant overflow bottle. The engine is
equipped with:
• an engine preheater (EPH), which provides easy starting characteristics.

• spin-on engine oil filter and a spin-on or suction side fuel filter for easier filter changes. The fuel filter may
also be equipped with a thermostatically controlled fuel heater.

• an electronic battery charger which converts generator or standby alternating current to direct current for
battery charging.

Refer to Section 2.7 for engine data.

2.3.2 Engine Air System The air cleaner prolongs the life and performance of the engine by preventing dirt and
grit from getting into the engine and causing excessive wear on all operating parts. It is the responsibility of the
operator to give the air cleaner equipment regular and constant attention in accordance with the instructions. An
air cleaner service indicator is connected at the outlet. Its function is to indicate when the air cleaner filter element
requires replacement. (Refer to Section 8.6.10). The system may be fitted with an intake air temperature sensor
(IAT) and a manifold absolute pressure transducer (MAP). These sensors are installed when Carrier Transicold
factory monitoring of the air system is required.

2.3.3 Engine Controls

a. Fuel/Speed Actuator (FSA) The FSA combines the fuel shutoff solenoid and speed control solenoid into one
component. Fuel supply to the injectors and engine speed is controlled by varying rod position in accordance with
the signal from the control system. In order to ease the load on the system, speed transition (high to low and low
to high) is ramped up or down over a 10 second period. The FSA is located on the front of the gear case cover.

b. Engine Speed Sensor (ENSSN) The ENSSN provides the control system with information on the speed at
which the engine is running. The ENSSN is located in the gear case cover above the engine oil filter.

c. Rack Position Sensor (RPS) The RPS provides the control system with engine fuel rack (throttle) position
information to be used to control the engine and refrigeration system. The sensor is located on the injection pump.

d. Engine Oil Pressure Switch (ENOPS) The ENOPS is normally open and closes on pressure rise to signal to
the control system the engine has sufficient oil pressure for operation. There is a 15 second delay after the engine
starts to allow the oil pressure to build up before the control system looks at the input from this switch. The switch
is located in the oil filter mounting assembly.

e. Engine Coolant Temperature Sensor (ENCT) The ENCT is a thermistor type sensor that provides the control
system with engine coolant temperature information to be displayed, recorded in the DataLink data recorder and
used to control the engine and refrigeration system. The sensor is located on the starter side of the engine near
the #4 injector.

62-11640 2–6
2.3.4 Generator (GEN) The generator is directly bolted to the engine and supplies nominal 460V/3Ø/60Hz power
when the engine is in high speed and nominal 345V/3Ø/45Hz power in low speed. The generator may be fitted
with a generator temperature sensor (GNT). This sensor is installed when Carrier Transicold factory monitoring of
the system is required.

2.3.5 Compressor The unit is fitted with a scroll compressor equipped with suction and discharge service valves
and an economizer connection. The compressor draws refrigerant gas from the evaporator and delivers it to the
condenser at an increased temperature and pressure. The pressure is such that refrigerant heat can be absorbed
by the surround- ing air at ambient temperatures.

2.3.6 Compressor Switches, Transducers and Sensors

a. Compressor Discharge Pressure Transducer (CDP) The CDP provides a signal to the control system
equivalent to pressure leaving the compressor. The reading is displayed, recorded in the DataLink data recorder
and used to control the refrigeration system. It is located in the discharge line leaving the compressor.

b. Compressor Suction Pressure Transducer (CSP) The CSP provides a signal to the control system
equivalent to pressure entering the compressor. The reading is displayed, recorded in the DataLink data recorder
and used to control the refrigeration system. It is located in the suction service valve.

c. High Pressure Switch (HPS) The HPS is normally closed and opens on pressure rise to signal the control
system to shutdown the refrigeration system if the discharge pressure rises above the switch setting. It is located
in the discharge service valve.

d. Compressor Discharge Temperature Sensor (CDT) The CDT is a thermistor type sensor that provides a
signal to the control system equivalent to the temperature of the gas leaving the compressor. The reading is
displayed, recorded in the DataLink data recorder and used to control the refrigeration system. It is located on the
compressor head.

e. Compressor Suction Temperature Sensor (CST) The CST is a thermistor type sensor that provides a signal
to the control system equivalent to the temperature of the gas entering the compressor suction service valve. The
reading is displayed, recorded in the DataLink data recorder and used to control the refrigeration system. It is
located on the line entering the service valve.

2.3.7 Liquid Injection Solenoid Valve (LIV) The LIV is opened during periods of high compressor discharge
temperature to inject refrigerant into the economizer connection to cool the compressor. It is located at the front of
the economizer.

2.3.8 Condenser Coil The condenser coil is a microchannel type and acts as a heat exchanger in which the
compressed refrigerant gas is lowered in temperature and condensed into a liquid. A portion of the condenser coil
is occupied by the subcooler, which removes heat from the refrigerant liquid leaving the receiver. Air movement
over the condenser, subcooler & radiator is provided by the condenser fans.

2.3.9 Economizer Circuit The economizer circuit consists of a compact brazed plate heat exchanger (Figure
2.1) and the economizer expansion valve (ECXV). Both are located above the compressor. In the economized
mode, the frozen and pull down capacity of the unit is increased by subcooling the liquid refrigerant entering the
evaporator expansion valve. Overall efficiency is increased because the gas leaving the economizer enters the
compressor at a higher pressure, therefore requiring less energy to compress it to the required condensing
conditions. To place the unit in the economized mode, the control system energizes (opens) the ECXV. The
ECXV controls the flow of liquid from the main liquid line through the economizer according to changes in
superheat of the refrigerant leaving the economizer.
 2–7 62-11640
2.3.10 Economizer Transducer and Sensor

a. Economizer Outlet Pressure Transducer (ECOP) The ECOP is located in the vapor injection line leaving the
economizer. It provides the control system with econo- mizer outlet pressure information to be displayed,
recorded in DataLink data, and used to determine the required position of the economizer expansion valve.

b. Economizer Outlet Temperature Sensor (ECOT) The ECOT is a thermistor type sensor located on the
suction line leaving the economizer. It provides the control system with economizer outlet temperature information
to be displayed, recorded in the DataLink data recorder and used to determine the required position of the
economizer expansion valve.

2.3.11 Ambient Air Temperature Sensor (AAT) The AAT is a thermistor type sensor that provides the control
system with the temperature of the air entering the condenser. This temperature information is displayed,
recorded in the DataLink data recorder and used to control the refrigeration system. The sensor is located behind
the front grill.

2.3.12 Compressor Suction Modulation Valve (CSMV) The CSMV opens and closes as required for capacity
control of the refrigeration system cooling cycle. It is located in the suction line just above the compressor.

2.3.13 Filter-Drier The filter-drier is a cylindrical shell containing a drying agent and filter screen. It is installed in
the liquid line and functions to keep the system clean and remove moisture from the refrigerant.

2.3.14 Receiver Liquid refrigerant from the condenser flows into the receiver. The receiver serves as a liquid
reservoir when there are surges due to load changes in the system, as a storage space when pumping down the
system and as a liquid seal against the entrance of refrigerant gas into the liquid line. The receiver is provided
with two bulls-eye sight glasses, for the observation of liquid level & moisture content, and a fusible plug.

2.3.15 AutoFresh Air Exchange As perishable products respire, they consume oxygen (O 2) and give off carbon
dioxide (CO2). This will eventually cause the atmosphere in a refrigerated compartment to have higher levels of
CO2 and lower levels of O2. This may adversely affect shelf life of some sensitive perishable products. When
transporting these products, it may be desir- able to maintain normal atmospheric conditions (prevent build up of
CO2 and depletion of O2) by using fresh air exchange, in addition to accurate temperature control. AutoFresh Air
Exchange (Figure 2.2) controls the amount of fresh air entering the refrigerated compartment without manual
intervention while in transit. AutoFresh Air Exchange can also be used to lower humidity level in a refrigerated
compartment if ambient air has a lower humidity level. AutoFresh Air Exchange is a factory-installed option, as it
requires a modified evaporator pod. When air is being exchanged, two air ports open. The upper port allows fresh
ambient air to enter while stale air exits through the lower port.

2.4 EVAPORATOR SECTION

The evaporator (Figure 2.3) fits into a rectangular opening in the upper portion of the front wall of the refrigerated
compartment. When the unit is installed, the evaporator section is located inside the compartment, and the con-
densing section is outside. The evaporator assembly consists of an evaporator coil, evaporator fan, evaporator
expansion valve, evaporator outlet pressure transducer, evaporator outlet temperature sensor, defrost termination
temperature sensor, supply temperature sensor and return air temperature sensor. Heating and defrost is
accomplished by electric heaters mounted on the coil.

2.4.1 Evaporator Coil The evaporator is a tube in fin type. The operation of the compressor maintains a reduced
pressure within the coil. At this reduced pressure, the liquid refrigerant evaporates at a temperature sufficiently
low enough to absorb heat from the air. Air movement over the coil is provided by the evaporator fan and motor
(EVM) assembly. The electric heaters (HTR1 & HTR2) are mounted on the inlet side of the coil and in the drain
pan. Automatic evap- orator coil defrosting is initiated by either a defrost air switch (DAS - which senses the
pressure drop across the coil) or by the control system defrost timer. During defrost the refrigeration system is
shut down and the evaporator fan and heaters operated as required by the defrost mode.

62-11640 2–8
2.4.2 Evaporator Expansion Valve (EVXV) The EVXV is an automatic device which controls the flow of liquid to
the evaporator according to changes in super- heat of the refrigerant leaving the evaporator. The expansion valve
maintains a relatively constant degree of super- heat in the gas leaving the evaporator regardless of suction
pressure. The valve has a dual function - automatic expansion control and prevention of liquid return to the
compressor.

2.4.3 Evaporator Switches, Transducers and Sensors

a. Evaporator Outlet Pressure Transducer (EVOP) The EVOP is located in the suction line near the evaporator
expansion valve. It provides the control system with evaporator outlet pressure information to be displayed,
recorded in the DataLink data recorder and used to deter- mine the required position of the evaporator expansion
valve.

b. Evaporator Outlet Temperature Sensor (EVOT) The EVOT is a thermistor type sensor located on the suction
line near the evaporator expansion valve. It provides the control system with evaporator outlet temperature
information to be displayed, recorded in the DataLink data recorder and used to determine the required position of
the evaporator expansion valve.

c. Evaporator High Temperature Switch (EVHTS) EVHTS is a safety switch which opens on a temperature rise
to de-energize the electric heaters if the temperature reaches the cutout point. It is located on the curbside tube
sheet of the evaporator coil.

d. Defrost Termination Temperature Sensor (1DTT) The defrost termination temperature sensor is located on
the roadside tube sheet of the evaporator coil. It provides the control system with evaporator temperature
information to be displayed, recorded in the DataLink data recorder and used to determine termination of defrost.

e. Return Air Temperature Sensor (1RAT / RAT2) 1RAT & RAT2 (if equipped) are thermistor type temperature
control probe which provides the control system with information on the temperature of the air entering the
evaporator section. The reading is displayed, recorded in the DataLink data recorder and used to control the
refrigeration system. It is located on a bracket behind the center of the return air grille.

f. Supply Air Temperature Sensor (1SAT) The 1SAT is a thermistor type temperature control probe which
provides the control system with information on the temperature of the air leaving the evaporator section. The
reading is displayed, recorded in the DataLink data recorder and used to control the refrigeration system. It is
located in the supply air outlet housing.

2.5 SYSTEM OPERATING CONTROLS & COMPONENTS

2.5.2 Automatic Start-Stop Standard equipment includes an auto start-stop feature. This feature provides
automatic cycling of the diesel engine or compressor, which in turn offers an energy efficient alternative to
continuous operation of the system with control of temperature accomplished by alternate cooling and heating of
the supply air (evaporator outlet air).

a. Power Control Module The power control module (PCM - see Figure 2.5) is responsible for
distribution of power from the battery to the system components, when starting, and then from the battery
charger to the system components and to the battery (for charging) once power is available. The module
houses the system relays, low voltage fuses and the DC current transformer (CT1). The current trans-
former provides a reading of the total 12 VDC system current draw (amps) to the main microprocessor at
terminal 2MM12 (see schematic diagram, Section 10).
2–11 62-11640
b. Main Microprocessor Module The main microprocessor module (MM) houses the main system
microprocessor. The module is totally self con- tained and does not contain any serviceable components.

c. SVM Module The stepper valve module (SVM) houses the CSMV, EVXV & ECXV operating microprocessor.
The module is totally self contained and does not contain any serviceable components.

d. Microprocessor Status LED Microprocessor activity within the main microprocessor SVM Module or
contractor control boards can be deter- mined by observing the status LED’s. Module LED’s are located just to the
right of the module bar code while con- tactor control board LED’S are visible through small openings in the
bottom mounting bracket. An LED will:
• blink, green in color, once per second to indicate that the microprocessor is operating correctly

• be off indicating no power to the module

• be on steadily, green in color, to indicate that the microprocessor is not communicating (check CAN bus)

• be on steadily, red in color, to indicate an internal failure or loss of software.

e. Contactor Control Boards The contactor control boards (1CCB & 2CCB - see Figure 2.4) are slave boards
that contain the necessary soft- ware to control the contactors in accordance with the unit model programmed into
the main microprocessor. The boards communicate with the control system through the CAN network.
f. AC Current Sensor The current sensor (CT2, CT3 & CT4, Figure 2.4) provides a reading of each individual
AC line current draw (amps) to the main microprocessor through the CAN bus from 1CCB at terminals 1CCB-12, -
34, -10 & -31 (see schematic diagram, Section 10).

g. High Voltage Transformer (HVT) The high voltage transformer (Figure 2.4) provides a reading of line voltage
to the main microprocessor through the CAN bus from 1CCB at terminals 1CCB-19 & -35 (see schematic
diagram, Section 10).

h. Engine Control Unit (ENCU) The ENCU (Figure 2.2) is a microprocessor based unit which controls the
operation of the engine. The ENCU communicates with the control system through the CAN network and sends
information on engine speed, oil pres- sure and coolant temperature to the control system to be displayed in the
Advanced User Unit Data and recorded in the DataLink data recorder. The ENCU also communicates with the
main microprocessor to control overall sys- tem balance. The ENCU is mounted on the frame near the fuel filter.

i.Overload Ground Fault Module (OGF) The OGF, LED

see Figure 2.6, is located in the control box (Figure
2.4). The module has two electrical safety fea- tures
which are active in both Engine and Electric Operation:

1. Overload protection.

2. Ground Fault (Leakage).

In each case, the 00100 OVERLOAD/GROUND

FAULT alarm is activated and the unit shuts down.
When ground leakage is detected, the red LED on the
OGF module will be on continuously.

j. Display Module (DM) Display The control system will display the refrigerated compartment
temperature on the left and compartment setpoint on the right. The control system may be configured to
display the setpoint in either whole numbers or with tenths of a degree. The temperature description will
be followed by a letter indicating the information is in degrees Fahrenheit (F) or degrees Centigrade (C).
Message Center Messages generated by the control system are displayed in the MessageCenter.
Details of the messages are described in Section 6. START/RUN-OFF Switch (SROS) - When placed in
the START/RUN position, this switch provides power to start the unit. The main microprocessor performs
a self-test. Then setpoint and compartment temperatures are dis- played. To stop the unit, place the
SROS in the OFF position.

• ALARM - The ALARM key allows viewing of the alarms stored in the system.

• UP ARROW and DOWN ARROW - These keys allow scrolling through the selections presented.

• EQUAL (ENTER) - The EQUAL key is used to confirm a selection and lock it into memory.

• START-STOP/CONTINUOUS - Pressing this key toggles between Start-Stop and Continuous Operation.

• DEFROST - Used to manually initiate a defrost cycle when the required conditions are met.

• MENU - Pressing the MENU key displays the various soft keys in the MessageCenter. The selections offered
are dependent on the operator’s status: Driver, Advanced User or Technician. Refer to Section 3 for Driver &
Advance User mode and Section 5 for Technician mode menu selection descriptions.

• The USB Interface Port - Used for installing software updates, options, configurations, functional parame-
ters and downloading of data from the Data Link data recorder.

2.6 OPTIONS

2.6.1 Light Bar The Light Bar is an external indicator Figure 2.8 Light Bar
light which can be seen in the driver’s rear view mirror
from the cab of the tractor. The green LED indicates
“STATUS OK”. The amber LED indicates “CHECK
UNIT”. The amber light is illuminated when the APX AMBER
Control System illumi- nates the alarm light. Alarms
can be read on the dis- play. For units with EES
installed, the amber light will also be illuminated when
the EES System is in Service Mode. This does not GREEN
affect unit operation.

2.6.2 Remote Switch(es) The unit is provisioned to connect remote switches (DS/REMS1/REMS2) directly to the
control system through the REM connector to the SVM.
• Two types of switches may be used:

1. A switch with contacts that are open when the switch is activated.

2. A switch with contacts that are closed when the switch is activated.
• Four Configurations are available for each switch.

1. Activate an alarm only while the switch is activated. 2. Activate an alarm and shut the unit down while the
switch is activated. The unit will remain shut down for a min-
 imum of 3 minutes under this setting. 3. Activate the alarm and bring the
engine into low speed while the switch is activated. 4. Record the switch activation in
the DataLink data recorder.
• If configured to shut the unit down or bring the engine to low speed an additional choice will be available. The
additional choice allows the unit to be set so that the configured action will always take place OR the
configured action will only take place when the ambient temperature is below a certain temperature. For
example, if the shutdown/low speed temperature choice is set to 77°F (25°C) the unit will only shutdown/ go to
low speed if the ambient temperature is below 77°F (25°C).

• Additionally a Functional Parameter “override” setting will be available for each switch configured to shut the
unit down. The Functional Parameter may be set to “YES” or “NO”. If the Parameter is set to “NO” the config-
ured action will not be overridden. If the Parameter is set to “YES”, the alarm will be activated but the unit will
not shutdown.

62-11640 2–14
2.6.3 Remote Temperature Sensor The unit is provisioned to connect remote temperature sensors (REMSN1,
REMSN2 & REMSN3) through the REM connector to the second contactor control board (2CCB). The system
may be configured to display the sensor reading in the Unit Data and to record the sensor reading in the DataLink
data recorder. A user specified name may be configured for each sensor. This name will be displayed, rather than
the default Remote Sensor #1, #2 or #3, name in the unit data list.

2.6.4 Fuel Level Sensor An optional fuel level sensor (Figure 8.10) supplies an input signal to the control system
as to the percentage of fuel remaining in the fuel tank. The control system will activate alarm 00001 LOW FUEL
LEVEL WARNING when the level reaches 15%, and (if configured to do so) shuts the engine down when the
level reaches 10%. The alarm is automatically cleared when the level is brought above 25%. The fuel tank level is
displayed in Unit Data.

2.6.5 Fuel Heater The optional fuel heater (Figure 2.2) applies heat to fuel in the fuel filter. Heating the fuel
dissolves/prevents paraf- fin wax crystals (and ice) that form when diesel fuel is chilled thus enabling the water
separator to work more effi- ciently and to prevent the filter from plugging with wax and/or ice crystals. When the
ambient air sensor is reading 77°F (25°C) or lower, the control system will enable this circuit. Also, the heater is
fitted with an internal temperature switch (FHTS) which will close on a temperature fall to energize the heater
element, and open on a temperature rise to de-energize the heater element.

2.6.6 Electric Fuel Pump The optional electric fuel pump (Figure 8.8) is mounted at the fuel tank location and
assists the engine mounted mechanical pump in transferring fuel from the tank to the engine. The pump is
activated by the control system whenever engine operation is required.

2.6.7 Remote Panel The unit may be fitted with an optional remote control panel. The remote panel, which is very
similar to the display module, displays compartment setpoints, compartment temperatures and operating modes
(heat, cool or defrost). The setpoint may be modified and the unit may be started and stopped using the remote
panel. This compact remote panel can be mounted to suit the individual operator’s preferences - on the front
bulkhead, or in the compartment (including in the wall itself). Remote Panel keys, soft keys and alarm indicators
are in the same locations as the main APX display module.

2.12 SAFETY DEVICES

The system is protected from high pressure conditions which may occur when exposed to very high temperatures
(such as a fire) by a fusible plug mounted in the receiver. Under very high temperature conditions (refer to
Section 2.9) the plug will melt, releasing the refrigerant pressure. System components are protected from
damage caused by unsafe operating conditions by automatic shut-down of the unit when such conditions occur.
This is accomplished by the safety devices listed in the following table and the fuses shown in Figure 2.4 and
Figure 2.5.

Unsafe Conditions Safety Device Device Setting

Excessive operating pressure High Pressure Switch (HPS) Section 2.9

2.13 REFRIGERATION CIRCUIT DURING COOLING

When cooling, the unit operates as a vapor compression refrigeration system. The main components of the
system are:

• scroll compressor

• air-cooled condenser

• evaporator expansion valve

• direct expansion evaporator

• economizer circuit

The refrigeration system will operate in one of three modes; Standard, Economized or Null. In addition, the
system may also operate in Liquid Injection mode. At start and during periods of high refrigeration system load,
the system will operate in standard mode. This allows the system to place the unit in operation at reduced
capacity and measure actual load. If the microprocessor calculates additional capacity is required and power is
available (periods of high load or during pull-down), the system will transition to economized mode.

2.13.1 Standard Mode In standard mode, (see Figure 2.9), the compressor raises the pressure and the
temperature of the refrigerant and forces it into the condenser channels. The condenser fans circulate
surrounding air over the outside of the condenser. The channels have fins designed to improve the transfer of
heat from the refrigerant gas to the air. This removal of heat causes the refrigerant to condense. Liquid refrigerant
leaves the condenser and flows to the receiver. The receiver stores the additional charge necessary for low
ambient operation. The receiver is equipped with a fusible plug. The refrigerant leaves the receiver and flows
through the liquid line service valve to the subcooler. The subcooler occupies a portion of the main condensing
coil surface and gives off further heat to the passing air. The refrigerant then flows through a filter-drier where an
absorbent keeps the refrigerant clean and dry. The liquid then flows through the economizer (which is not active in
standard mode) and into the evaporator expansion valve (EVXV). The EVXV reduces the pressure of the liquid
and meters the flow of liquid refrigerant to the evaporator to obtain maximum use of the evaporator heat transfer
surface. The refrigerant pressure drop caused by the expansion valve is accompanied by a drop in temperature
so the low pressure, low temperature liquid that flows into the evaporator tubes is colder than the air that is
circulated over the evaporator tubes by the evaporator fan. The evaporator tubes have aluminum fins to increase
heat transfer; therefore heat is removed from the air circulated over the evaporator. This cold air is circulated
throughout the refrigerated compartment to maintain the cargo at the desired temperature. The transfer of heat
from the air to the low temperature liquid refrigerant causes the liquid to vaporize. This low temperature, low
pressure vapor passes the evaporator outlet temperature and pressure sensors (EVOT and EVOP) which aid in
calculation of superheat. The vapor then returns to the compressor through the compressor suction modulation
valve (CSMV). The CSMV controls the flow of refrigerant entering the suction line, thereby matching the load to
the compressor capacity.
 2–19 62-11640
2.13.2 Economized Mode In the economized mode the “main” refrigeration system operates the same as in the
Standard Mode except the control system operates (opens) the economizer expansion valve (ECXV). With the
economizer expansion valve operating (see Figure 2.10), the capacity of the unit is increased by subcooling the
liquid refrigerant entering the evaporator expansion valve. Liquid refrigerant for use in the economizer circuit is
taken from the main liquid line as it leaves the filter drier. This liquid refrigerant flows through the economizer
expansion valve (ECXV) and the economizer heat exchanger internal passages absorbing heat from the liquid
refrigerant flowing to the evaporator expansion valve. Overall efficiency is increased because the gas leaving the
economizer enters the compressor at a higher pressure, therefore requiring less energy to compress it to the
required condensing conditions. There are two levels of economized mode, full economized mode and limited
economized mode. Limited economized mode is entered when the control system requests higher capacity than
standard mode but engine power or system current limit will not allow full economizer superheat control.

2.13.3 Null Mode The system will enter null mode during periods where no cooling or heating is required and
system is in continuous run. In null mode the compressor and heaters are shut down while evaporator fans
continue to operate. Condenser fan will operate if engine cooling is required. The system may also enter the null
mode while in start stop if required time, coolant temperature or battery condition parameters have not been met.

2.13.4 Liquid Injection Mode The control system monitors the signal provided by the compressor discharge
temperature sensor. If compressor temperature rises to the limit (refer to Section 2.9), the system will enter Liquid
Injection Mode. In this mode the normally closed liquid injection valve (LIV) will be pulsed or opened as required
to allow flow of refrigerant into the economizer line, to cool the compressor.

2.14 HEAT AND DEFROST

In Heat and Defrost Modes, the compressor is de-energized. In Heat Mode, the coil mounted heaters and
evaporator fans are energized. Air flowing over the warm coil is circulated throughout the refrigerated
compartment to maintain cargo at desired temperature. If the control system is Configured to allow Natural
Defrost, and the compartment temperature is above freezing defrost may be accomplished using a combination of
coil heaters and return air. If compartment temperature is below freezing or not sufficiently warm enough to
defrost the coil, the evaporator fans are de-energized and the coil mounted heaters energized.

3.6 INTELLISET

Products carried or stored in a refrigerated compartment require a multitude of refrigeration unit settings that must
be checked and, if required, reset each time a new product is loaded. The APX control system offers the settings
necessary to meet these requirements. IntelliSet is a feature that allows pre-selection and naming of the
necessary settings for over 40 different products. The operator may then call up the settings by simply selecting
the assigned IntelliSet name. For example: A load of apples may require setting the APX Control System for
continuous operation at 35°F (1.7°C) with a defrost every 3 hours while a load of cheese may require the same
operation with setpoints ranging from 35°F to 42°F (1.7°C to 5.6°C) and a load of ice cream requires Start-Stop
operation at -22°F (-30°C) with defrost at 12 hour intervals. The settings required for each product may be entered
into the APX Control System and then locked so they cannot be changed. In the case of the load of cheese, the
range of setpoints may be locked, leaving the operator the ability to change the setpoint within the locked range.
When a load of apples is going to be picked up, the operator simply selects “APPLES” from the IntelliSet menu;
 for cheese, “CHEESE” is selected; for ice cream, “ICE CREAM” is selected. With each selection, the APX Control
System automatically re-programs the settings to provide the best temperature control, fuel economy, and
performance for that particular product.
NOTES
• The above settings are examples of possible settings. Factory IntelliSets are available from your authorized
Carrier Transicold Truck/Trailer dealer

• IntelliSet may be pre-programmed as “IntelliSleep” which allows Sleep Mode to be entered by simply
changing to that IntelliSet.

• Range Protect may be applied to as many IntelliSets as desired. Range Protect is designed to prevent
freezing or overheating of non-sensitive cargo by locking the unit in Start-Stop Operation when the
compartment temperature is in the preset range (default range is 35 to 70°F, 1.6 to 21.1°C). Range Protect
offers increased fuel savings over normal Start-Stop Operation.

data can be downloaded from the DataLink data recorder using either the TRU-Tech/TRU-View program or a
Data Transfer USB memory device. The DataLink data recorder reads the same input information as the control
system (Functional Parameters, Con- figurations, and Unit Data) at all times. The DataLink data recorder records
events as they occur, such as setpoint changes and defrost initiation and termination, and also records all data
values including temperature sensors and pressure transducers in either averaged or snapshot format at selected
intervals. The following intervals are available for sensor recording:
• 1 Minute • 15 Minutes
• 30 Minutes
• 2 Minutes
• 1 Hour
• 5 Minutes
• 2 Hours
• 10 Minutes
• 4 Hours

3.11.1 APX Control System Information The APX Control System

information that may be recorded is as follows:
• DataLink data recorder time clock date / time • Controller (main microprocessor) Serial Number
• Setpoint • Controller (main microprocessor) Software
Revision
• DataLink data recorder settings (Logging Inter
vals, Events and Sensors) • Pretrip Start/End
• Trailer (asset or car) ID • Functional Parameters
• Unit Serial Number • Control System Configurations
• Unit Model Number • Current System Operating Mode

3.11.2 Data Recording The DataLink data recorder data comes from four general categories of information: 1.
APX Control System Information as described in the preceding Section 3.11.1 2. Sensor Data This information is
recorded at pre-determined intervals as a snapshot of the sensor at the time of the recording, or an average of the
sensor readings since the last recording based on 1 minute increments. The user can determine which sensor(s)
will be recorded, whether snapshot or averaged readings are preferred and at what time intervals. (Snapshot
readings are also taken at the beginning and end of defrost and at the time of a shutdown alarm.) All of the
sensors and transducers that may be read under Unit Data (refer to Table 3–1) may be included or excluded from
the recordings. 3. Event Occurrences This information is any additional data that is recorded on a “when it occurs”
basis. Events are recorded by the recorder as they occur. An Event is defined as something that happens and
may include:
• Setpoint change • Unit Mode
• Control Mode
• Defrost cycle start/Defrost cycle end
• Door and Remote switch activations
• START/RUN - OFF switch on (START/RUN
position) • Hour Meter readings (Hour meters are recorded
at midnight or the first time of day the START/
• Pretrip start
RUN- OFF switch is toggled from the OFF posi-
• Pretrip end tion. There will be no hour meter readings when the
 switch is in the OFF position.

4. User Area Data The User or service technician may enter a Comment into the DataLink data recorder using the
TRU-Tech pro- gram.

3.11.3 Data Downloading The data within the DataLink data recorder can be downloaded using either the TRU-
Tech/TRU-View program with a PC-USB service cable connected to the USB interface port or with a Data
Transfer USB memory device (refer to Section 5.3.3).

3.11.4 DataLink Data Recorder Power-Up The DataLink data recorder records data the entire time the
START/RUN - OFF switch is in the START/RUN posi- tion. A Configuration exists which allows the user to select
whether an additional 8 hours of sensor data be recorded after the switch is placed in the OFF position, or to stop
recording at the same time the switch is placed in the OFF position. The factory setting is to record the additional
8 hours so the temperatures will be recorded during the unloading, fueling or other times when it may be
necessary to turn the unit off. (Refer to Section 5.2.3.)

the com- pletion of any defrost cycle, the MessageCenter will return to the default display.
3. If the conditions for defrost are not met, the MessageCenter will display “CANNOT START DEFROST
CYCLE” for 5 seconds. This message will be activated when:
• The box temperature is too warm. Defrost may be entered when the defrost termination temperature
sen- sor (1DTT) is below 40°F (4.4°C) or the supply air temperature sensor (1SAT) is below 45°F (7.2°C)
OR
• The engine has not run at least 15 seconds after starting OR
• The unit is in PC Mode OR
• The unit is in Pretrip OR
• There is an active shutdown Alarm.
Defrost may also be initiated automatically at preset intervals by the system defrost timer or by the defrost
air switch. The Defrost Mode terminates when the defrost termination temperature (1DTT) rises higher
than 55°F (12.8°C). Should the defrost cycle not end after a maximum of 45 minutes the defrost cycle is
terminated automatically and alarm 00054 DEFROST NOT COMPLETE will be activated. If the alarm is
activated, the system will wait 1.5 hours of unit running time before attempting an automatic defrost cycle.
Pressing the manual defrost key will override this mode and start a defrost cycle.
TIP The Manual Defrost Key can be used at any time to start a Defrost Cycle as long as the preceding
conditions are met.
