Introduction
There is nothing complicated about operating and maintaining your Thermo King unit, but a few minutes studying this manual will be time well spent.
Performing pre-trip checks and enroute inspections on a regular basis will minimize on-the-road operating problems. A regular maintenance program will also help to keep your unit in top operating condition. If factory recommended procedures are followed, you will find that you have purchased the most efficient and dependable temperature control system available.
All service requirements, major and minor, should be handled by a Thermo King dealer for four very important reasons:
• They are equipped with the factory recommended tools to perform all service functions
• They have factory trained and certified technicians
• They have genuine Thermo King replacement parts
• The warranty on your new unit is valid only when the repair and replacement of component parts is performed by an authorized Thermo King dealer.
IMPORTANT: This manual is published for informational purposes only and the information furnished herein should not be considered as all-inclusive or meant to cover all contingencies. If more information is required, consult your
Thermo King Service Directory for the location and telephone number of the local dealer.

Safety Precautions
Thermo King recommends that all services be performed by a
Thermo King dealer. However, there are several general safety practices which you should be aware of:
WARNING: Always wear goggles or safety glasses when working with or around the refrigeration system or battery. Refrigerant or battery acid can cause permanent damage if it comes in contact with your eyes.
WARNING: Keep hands and loose clothing clear of fans and belts at all times when the unit is operating or when opening or closing compressor service valves.
WARNING: Exposed coil fins can cause painful lacerations. Service work on the evaporator or condenser coils is best left to a certified Thermo King technician.
CAUTION: Use extreme caution when drilling holes in the unit. Drilling into electrical wiring or refrigerant lines could cause a fire. Never drill into structural components.
Automatic Start/Stop Operation
This unit is capable of automatic operation and may start at any time without prior warning.
WARNING: The unit may start at any time when the controller is turned on. The controller display lights up when the controller is turned on.
WARNING: Units equipped with electric standby may start at any time when the unit is connected to live electric power and the controller is turned on.
WARNING: Be sure to press the OFF key to turn the controller off before opening doors or inspecting any part of the unit.
Battery Installation and Cable
Routing
WARNING: Improperly installed battery could result in a fire or explosion! A Thermo King approved battery must be installed and properly secured to the battery tray.
WARNING: Improperly installed battery cables could result in fire or explosion! Battery cables must be installed, routed and secured properly to prevent them from rubbing, chaffing or making contact with hot, sharp or rotating components.
WARNING: Do not attach fuel lines or any additional wiring harnesses to the battery cables as this could cause an electrical fire!
CAUTION: Do not connect other manufacturer’s equipment or accessories to the Thermo King unit.
This could result in severe damage to equipment and void the warranty!
Safety Precautions
CAUTION: Set all unit electrical controls to the
OFF position before connecting battery cables to the battery to prevent unit from starting unexpectedly and causing personal injury.
CAUTION: Always wear protective clothing, gloves and eye wear when handling and installing batteries. Battery acid can cause serious burns when exposed to eyes or skin. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters your eye, immediately flood it with running cold water for at least twenty minutes and get medical attention immediately.
CAUTION: Always cover battery terminals to prevent them from making contact with metal components during battery installation. Battery terminals grounding against metal could cause the battery to explode.
9
Safety Precautions
Electrical Hazard
CAUTION: Be sure to turn off the high voltage power supply, and disconnect the electric cable before working on the unit. Units with electric standby present a potential electrical hazard.
Refrigerant
Although fluorocarbon refrigerants are classified as safe, observe caution when working with refrigerants or around areas where they are being used in the servicing of your unit.
DANGER: Fluorocarbon refrigerants may produce toxic gases. In the presence of an open flame or electrical short, these gases are severe respiratory irritants CAPABLE OF CAUSING DEATH.
DANGER: Fluorocarbon refrigerants tend to displace air and can cause oxygen depletion which could result in DEATH BY SUFFOCATION. Provide adequate ventilation in enclosed or confined areas.
WARNING: Fluorocarbon refrigerants evaporate rapidly, freezing anything they contact if accidentally released into the atmosphere from the liquid state.
Refrigerant Oil
Observe the following precautions when working with or around refrigerant oil:
WARNING: Always wear goggles or safety glasses to protect eyes from refrigerant oil contact.
WARNING: Protect skin and clothing from prolonged or repeated contact with refrigerant oil.
Rubber gloves are recommended.
WARNING: Wash thoroughly immediately after handling refrigerant oil to prevent irritation.
10
Safety Precautions
First Aid
First Aid–Refrigerant
Eyes: For contact with liquid, immediately flush eyes with large amounts of water. Get prompt medical attention.
Skin: Flush areas with large amounts of warm water. Do not apply heat. Wrap burns with dry, sterile, bulky dressing to protect from infection or injury. Get prompt medical attention.
Inhalation: Move victim to fresh air and restore breathing if necessary. Stay with victim until arrival of emergency medical personnel.
First Aid–Refrigerant Oil
Eyes: Immediately flush eyes with large amounts of water for at least 15 minutes while holding the eyelids open. Get prompt medical attention.
Skin: Remove contaminated clothing. Wash thoroughly with soap and water. Get medical attention if irritation persists.
Inhalation: Move victim to fresh air and restore breathing if necessary. Stay with victim until arrival of emergency personnel.

CYCLE-SENTRY
™
Start/Stop
System
The CYCLE-SENTRY Start/Stop fuel saving system provides optimum operating economy.
WARNING: Turn the unit off by pressing the OFF key before opening doors or inspecting any part of the unit. The unit can start at any time without warning if it has been turned on by pressing the ON key.
The CYCLE-SENTRY system automatically starts the unit on microprocessor demand and shuts down the unit when all demands are satisfied.
The system monitors and maintains the compartment temperature, the engine block temperature, and battery charge levels at a point where quick, easy starts are possible.
Defrost
Frost will gradually build up on the evaporator coils as a result of normal operation. Periodically this frost must be melted to prevent a loss of cooling and airflow.
Defrost is accomplished by passing hot refrigerant gas through the evaporator coil, thus melting the frost (or ice). Melted frost drains out of the unit onto the ground through the drain tubes.
The defrost damper closes during defrost to prevent warm air from entering the cargo area. The optional electric heater strips are also energized in defrost during electric standby operation.
Defrost can be initiated at any time the evaporator coil temperature is below 42 F (5.5 C).
There are two methods of defrost initiation:
SR-3 Microprocessor Controller: The Microprocessor
Controller is programmed to automatically initiate timed and forced defrost cycles. The SR-3 uses temperature sensors to determine if forced defrost is required.
Manual Defrost: Manual Defrost allows the operator to initiate a defrost cycle by pressing the D
EFROST key. See
“Initiating a Manual Defrost Cycle.”
30
Unit Description
DAS - Data Acquisition System
(Optional)
The DAS (Data Acquisition System) monitors and records the temperatures of (up to) six additional sensors. The sensors are independent from the microprocessor controller and are normally located in the truck box to monitor load temperatures.
DAS data can be downloaded through a serial port to an IBM ®
PC compatible computer. WinTrac™ 4.0 (or higher) software is used to view and analyze the data. Brief reports can be printed on a microprinter connected to the serial port.
CargoLink™ (Optional)
CargoLink is a wireless sensor system. The main components are the coordinator module, interconnect harness, antenna, and wireless sensors. The coordinator module receives information from the wireless sensors through the antenna, and communicates with the controller through the interconnect harness. Currently, only wireless door switches are available.
Other wireless sensors will be available in the future. Refer to
TK 55151 the Truck and Trailer Edition CargoLink Installation
Manual for information about installing the CargoLink system and sensors, and troubleshooting problems with the system.
Electric Standby (Model 50 Units
Only)
The Electric Standby option allows the unit to be operated on either the diesel engine or external electric power.
DANGER: High voltage AC power is present whenever the unit is operating in the Electric mode and whenever the unit is connected to external standby power. Voltages of this magnitude can be lethal. Exercise extreme caution when working on the unit.
31
Unit Description
Standard Model 50 Features
The following features are standard equipment on units equipped with Electric Standby.
Automatic Diesel/Electric Selection: The unit will automatically switch to electric operation when a power cord is connected and the standby power is switched On.
Overload Relay: The overload relay is self-resetting.
Hot Gas Heat: Hot gas heat is utilized on all units.
Automatic Phase Correction: The control system features two motor contactors. This allows correct motor rotation regardless of phase rotation on the incoming power.
Optional Model 50 Features
The following features are available as options on units equipped with Electric Standby.
• Electric Heater Strips
• Auto Switching
Engine Compartment
Components
Coolant Expansion Tank: The coolant level and temperature inside the expansion tank are monitored by the base controller. If the coolant temperature becomes too high or the level becomes too low, an alarm will occur. The expansion tank must always be completely full of coolant when cool.
Coolant Overflow Bottle: The overflow bottle captures coolant expelled from the expansion tank during normal diesel operation. Coolant returns to expansion tank when the unit is off and coolant has cooled. Coolant level in the overflow bottle must always be at or above the FULL COLD mark of the bottle when cool.
The engine must have antifreeze protection to –30 F (–34 C).
Check and add coolant in the expansion tank and overflow bottle as needed.
CAUTION: Do not remove expansion tank cap while the coolant is hot.
CAUTION: Do not add Green or Blue-Green coolants to cooling systems that use Red Extended
Life Coolants.
32
Unit Description
Engine Oil Dipstick: Use the engine oil dipstick to check the engine oil level.
Receiver Tank Sight Glass: The receiver tank sight glass is used to assist in checking the amount of refrigerant in the system.
Compressor Oil Sight Glass: The compressor oil sight glass is used to check the relative level of compressor oil in the compressor sump.
Unit Protection Devices
High Pressure Cutout Switch (HPCO): This normally closed switch monitors the discharge pressure at the compressor. It opens on high discharge pressure to shut the unit down to prevent damage.
Suction Pressure Regulator (SPR): This component is a mechanical control device used to limit the suction pressure to the compressor. The valve controls suction pressure based on the actual system pressure. (Scroll compressor units: The SPR is not used if the unit is equipped with an ETV.)
Electronic Throttling Valve (ETV): (Scroll compressor units only.) This component is an electromechanical control device used to limit the suction pressure to the compressor. The valve is controlled by the microprocessor controller.
Engine Oil Pressure Switch/Sensor: The engine oil pressure switch/sensor is located on the filter head above the bypass oil filter. Engine oil pressure should rise immediately on starting. If engine oil pressure drops below 10 ± 2 psig (69 ±
14 kPa), the switch/sensor signals the microprocessor to stop the engine.
Preheat Buzzer: The preheat buzzer sounds when the
CYCLE-SENTRY system energizes the glow plugs. This should warn anyone near the unit that the CYCLE-SENTRY system is about to start the diesel engine.
Coolant Temperature Sensor: This sensor provides an engine coolant temperature input to the microprocessor. If the engine coolant temperature is too high, the controller stops the unit and records an alarm.
Electric Motor Overload Relay (Model 50): The overload relay protects the electric standby motor. The overload relay opens the circuit from the contactor to the electric motor if the motor overloads for any reason and an alarm will occur. The relay resets when the alarm code is cleared.
Fuses: Sizes and functions are described in the Specifications section of this manual.

Unit Operation
Log Alarms
Log Alarms are indicated for 60 seconds each time the unit is turned on. This level of alarm serves as a notice to take corrective action before the condition impacts unit performance. Maintenance items such as maintenance hourmeter time-outs are log alarms.
When the unit is turned on the display will show the Thermo
King Logo and then the "Configuring System" message. If log alarm(s) are present the Log Alarm notice will appear on the display for 60 seconds as shown. The amber K symbol of the remote indicator alarm light (if installed) will also be on during this period. The Standard Display will appear and the remote indicator alarm light will go to the white T symbol after 60 seconds.
NOTE: The Alarm Icon does not appear on startup with log alarms present.

Check Alarms
Check Alarms are indicated by an Alarm Icon in the display.
The amber K symbol of the remote indicator alarm light (if installed) will be on. This level of alarm serves as a notice to take corrective action before a problem becomes severe. The unit will run with check alarms but some features and functions may be inhibited.
63
Unit Operation
Shutdown Alarms
Shutdown alarms will be set if continued operation could cause damage to the unit or the load. Shutdown Alarms are indicated by the following:
• The Alarm Icon will appear in the display.
• The display and backlight will flash on and off.
• The display will switch from normal video to reverse video and back to normal video. (Light areas become dark and dark areas become light.)
• The remote indicator alarm light (if installed) will display only a row of LEDs at the bottom.
Shutdown alarms will force the unit into shutdown to prevent potential damage to the unit or load. The unit will remain in shutdown until the shutdown alarm is manually cleared.
Exceptions are some engine and electric shutdown alarms that become log alarms when switched to the alternate operating mode (diesel to electric or electric to diesel).
Prevent Alarms
Prevent Alarms are also indicated by a steady Alarm Icon in the display. The remote indicator alarm light (if installed) will be on. The unit will attempt to resolve the situation as shown below.
• The unit will be temporarily shut down if a Prevent Alarm is active.
• The unit will remain shut down for a timed restart interval or until the fault conditions are corrected.
• If the unit is in a temporary shutdown, Alarm Code 84
Restart Null will be present along with the associated
Prevent Alarm.
• The unit will restart and run (in most cases with forced reduced performance) to determine if continued operation is possible. The unit will run in this manner for a timed interval. If the unit is running with forced reduced performance, Alarm Code 85 Forced Unit Operation will also be present under some conditions.
• If the alarm does not reoccur during the timed running interval with reduced performance, the unit will return to full performance to determine if continued operation is
64
Unit Operation possible. The unit will run in this manner for a timed interval. If the unit is successfully able to return to full performance for the timed interval without the alarm re-occurring, the alarm is auto cleared and the unit will run normally.
• All Prevent Alarm events and conditions are logged by the
ServiceWatch Data Logger.
• In general, if the alarm condition re-occurs a defined number of times, the alarm is set as a shutdown alarm and no further restarts are possible.
NOTE: If the Restart After Shutdown feature in the Guarded
Access Menu is set for CONTINUOUS, then an unlimited number of restart attempts are allowed.
Pretrip Alarm Codes
If an alarm occurs during a Pretrip Test the alarm code will be displayed as Pretrip Alarm XX, where XX is the alarm code.
Alarm Codes When Switching Between
Diesel and Electric
If a shutdown alarm occurs that affects only diesel mode operation and the unit is switched to electric, the diesel mode shutdown alarm becomes an electric mode log alarm. This allows the unit to run in electric mode without clearing the shutdown alarm that is preventing diesel mode operation. If the unit is switched back to diesel mode, the alarm again become a diesel mode shutdown alarm and prevents unit operation.
In the same manner, if a shutdown alarm occurs that affects only electric mode operation and the unit is switched to diesel, the electric mode shutdown alarm becomes a diesel mode log alarm to allow diesel mode operation. If the unit is switched back to electric mode, the alarm reverts to an electric mode shutdown alarm and prevents unit operation. If the unit is configured for electric to diesel autoswitch, it automatically starts and runs in diesel mode if an electric shutdown occurs.
Alarm Code Notification
The Alarm Icon used in previous Thermo King controllers has been incorporated. If a Check alarm condition occurs the
Alarm Icon will appear in the display as shown in Figure 69.
65

Test with device amp checks will be performed. If the Pretrip
Test is entered with the unit running in either diesel or electric mode a Running Pretrip Test is performed, but the device amps checks are not performed. Test results are reported as PASS,
CHECK or FAIL when the Pretrip Test is completed. If an alarm occurs during a Pretrip Test the alarm code will be displayed as Pretrip Alarm XX, where XX is the alarm code.
Pretrip Test Conditions
• Current unit settings are saved and restored at the end of the Pretrip Test or if the unit is turned off and back on.
• Pretrip Test can be run in either Diesel or Electric Mode.
• The unit will auto switch from Diesel Mode to Electric
Mode or from Electric Mode to Diesel Mode during a
Pretrip Test if these features are enabled and the auto switch conditions occur.
Conditions where Pretrip Tests are not allowed
• If any shutdown alarms are present. Pretrip tests are allowed with some Check and Log alarms.
• If the unit is in Sleep Mode.
• If the unit is in Service Test Mode, Interface Board Test
Mode or Evacuation Mode.
89
Unit Operation
Pretrip Test Sequence
Pretrip tests proceed in the order shown below. A Full Pretrip
Test includes all tests. A Running Pretrip Test is started with the engine or motor running and does not include the Amp
Checks or Engine Start Check.
• Amp Checks - Each electrical control component is energized and the current drawn is confirmed as within specification.
• Engine Start - The Engine will start automatically.
• Defrost - If the coil temperature is below 45 F (7 C), a defrost cycle is initiated.
• RPM Check - The engine RPM in high and low speed is checked during the Cool Check.
• Cool Check - The ability of the unit to cool in low speed is checked.
• Heat Check - The ability of the unit to heat in low speed is checked.
• Report Test Results - The test results are reported as PASS,
CHECK or FAIL when the Pretrip Test is completed. If test results are CHECK or FAIL alarm codes will exist to direct the technician to the source of the problem.
Pretrip Test Considerations
When performing a Pretrip Test, the following issues should be considered.
• If running a Pretrip Test on a truck or trailer loaded with dry cargo, insure that proper airflow can occur around the load. If the load restricts airflow, false test results may occur. Also, SR-3 units have high refrigeration capacity which results in rapid temperature changes. Sensitive dry cargo may be damaged as a result.
• If running a Pretrip Test on a truck or trailer that has just been washed down, the extremely high humidity inside the truck or trailer may result in false test results.
• If running a Pretrip Test on a truck or trailer loaded with sensitive cargo, monitor the load temperature during the test as normal temperature control is suspended during a
Pretrip Test.
• Always perform Pretrip Tests with the truck or trailer cargo doors closed to prevent false test failures.
90
Unit Operation
Performing a Pretrip Test
If a Pretrip Test is initiated with the engine shut down a Full
Pretrip Test will be performed. If a Pretrip Test is initiated with the engine or motor running a Running Pretrip Test is performed.
• Before initiating a Pretrip Test, clear all alarm codes.
• To stop a Pretrip Test at any time, turn the unit off. Alarm
Code 28 Pretrip Abort will be set. Other alarms may also be set, depending upon test in progress when the test was terminated.

Loading and Enroute Inspections
Thermo King refrigeration units are designed to maintain the required temperature for the product being carried during its time in transit. Because of the unit’s unique design, special care is required during loading to prevent cargo spoilage.
Pre-Loading Inspection
1.
Inspect all door seals, including vent doors, for condition and a tight seal with no air leakage.
2.
Inspect the cargo compartment inside and out for damaged or loose skin and insulation.
3.
Inspect the inside of the cargo compartment for damaged walls, air ducts, floor channels or “T” flooring, clogged defrost drain tubes, and clogged or damaged floor channels which could block the air return, creating isolated areas in the load that are warmer than the desired temperature.
4.
Pre-cool the cargo compartment. Adjust the setpoint to the desired cargo temperature and allow the unit to run a minimum of 30 to 60 minutes (longer if possible) before loading. Check to be certain the setpoint temperature is correct for the cargo.
Pre-cooling before loading will remove residual heat and moisture from the cargo compartment and prepare it to receive the refrigerated load. Pre-cooling also provides a good test of the refrigeration system.
5.
Make sure products are pre-cooled to the proper temperature before loading. Any variance should be noted on the manifest.
6.
Supervise product loading to make sure that there is sufficient air space around and through the load so air flow is not restricted.
98
Loading and Enroute Inspections
Inspecting the Load
Never assume that the product has been loaded properly. Watch for and perform the following tasks. It takes only a few minutes and could save you or your employer considerable time and money later on.
1.
Make sure the unit is off before opening the cargo compartment doors. During operation, the unit blows out refrigerated air, and draws in outside air.
NOTE: The unit can be run with the doors open if the truck is backed into a refrigerated warehouse with tight door seals.
2.
Perform a final check of the load temperature. If the load is too hot or too cold, make a final notation on the manifest.
CAUTION: Make sure cargo is pre-cooled to the proper temperature before loading. The unit is designed to maintain temperature, not cool an above-temperature load.
3.
While inspecting to see that the cargo is loaded properly, make sure the evaporator inlets and outlets are not blocked.
4.
Close or supervise the closing of the cargo compartment doors. Make sure they are securely locked.
5.
Check to make sure the unit setpoint is set at the desired temperature as listed on the manifest.
6.
If the unit was stopped, restart using the appropriate starting procedure outlined in this manual.
7.
Repeat the after-start inspection.
8.
Defrost the unit 30 minutes after loading by starting a manual defrost cycle.
99
Loading and Enroute Inspections
Enroute Inspections
NOTE: Enroute inspections are recommended every four hours for the prevention of damage to the cargo.
1.
Note the setpoint to make certain no one has altered the setting since picking up the load.
2.
Note the return air temperature reading. It should be within the desired temperature range. If the return air temperature reading is not within the desired temperature range, it indicates one of the following: a.
The unit has not had sufficient time to pull down the temperature. Refer to log, if possible, for history of load (for example, above temperature load, properly pre-cooled cargo compartment, length of time on road).
b.
The unit is in defrost or has just completed defrost.
NOTE: You can cancel defrost by turning the unit off, then restarting the unit. c.
The evaporator is plugged with frost. Initiate a manual defrost cycle. The defrost cycle will be automatically terminated. d.
Improper air circulation within the cargo compartment. Inspect the cargo compartment (if possible) to determine if the evaporator fans are working and properly circulating the air. Poor air circulation can be due to improper loading of the cargo or shifting of the load, or the fan belt slipping.
WARNING: The unit may START automatically AT
ANY TIME while it is turned ON. Make sure to turn the unit OFF before opening unit doors or inspecting any part of the unit.
e.
The unit did not start automatically. If the unit cranked without starting, determine and correct the cause for not starting.
100
Loading and Enroute Inspections f.
The unit may have a low refrigerant charge. If liquid is not showing in the unit receiver tank sight glass, the refrigerant charge may be low. Adding refrigerant or repairing the refrigeration system requires a competent mechanic. Refer such problems to the nearest Thermo King dealer or authorized Service
Center, or call the Thermo King Cold Line telephone number shown on the inside back cover of this manual for referral.
NOTE: If the temperature in the compartment is not within the desired temperature range, repeat the Enroute
Inspection every 30 minutes until the compartment temperature comes within the desired temperature range.
CAUTION: Stop the unit if the compartment temperature remains outside the desired temperature range from the setpoint on two consecutive 30 minute inspections. Contact the nearest Thermo King
Service Center or your company office immediately.
Take all necessary steps to protect and maintain proper load temperature.
3.
Initiate a Manual Defrost cycle after each Enroute
Inspection.
