Unit Description
OptiSet Plus
OptiSet Plus is a group of programmable functions that control how the unit will operate with specific setpoints or named products. This assures that when a particular setpoint or named product is selected, the unit will always operate the same way.
This allows an entire fleet to be configured to match the customers’ needs. Contact your Thermo King dealer for information about programming OptiSet Plus.
FreshSet
FreshSet is included in OptiSet Plus. FreshSet is a demand base temperature control for fresh products. FreshSet modifies and adjusts unit airflow operation to control temperature and to maximize protection of cargo, while keeping operating costs to a minimum. Contact your Thermo King dealer for information about programming FreshSet.
ECO Pulldown Mode
This programmable feature allows the unit to operate in low speed during initial pulldown until the temperature in any one zone inside the trailer reaches 30F. At this point, it automatically switches the unit to high speed operation. For set points above 30F, the unit will operate in ECO Pulldown mode until set point is achieved, possibly never operating in high speed mode.
Operating the unit in low speed pulldown can save up to 15% fuel during the initial pulldown without significantly increasing the overall unit run time.
All Thermo King Multi-Temperature units come factory set with the ECO Pulldown Mode enabled. Contact your Thermo
King dealer for further information about ECO Pulldown
Mode.
Defrost
Frost gradually builds-up on evaporator coils as a result of normal operation. The unit uses hot refrigerant to defrost the evaporator coil. Hot refrigerant gas passes through the evaporator coil and melts the frost. The water flows through collection drain tubes onto the ground. The methods of defrost initiation are Automatic, and Manual.
Automatic Defrost:
The SR-4 MT automatically initiates timed or demand defrost cycles. The SR-4 MT microprocessor can be programmed to initiate timed defrost cycles at intervals of 2, 4, 6, 8, or 12 hours. Demand defrost cycles occur if the
22
Unit Description
differences between the return air temperature, discharge air temperature, and coil temperature exceed certain limits. The unit can enter defrost cycles as often as every 30 minutes if required.
Manual Defrost:
In Manual Defrost Mode, the operator initiates a defrost cycle. See “Initiating a Manual Defrost
Cycle.”
NOTE: The unit will not perform a Manual Defrost Cycle unless the unit has been turned on with the
O
N
key, the unit is running in Continuous or CYCLE-SENTRY Mode (or shut down in CYCLE-SENTRY Null Mode), and the coil temperature is below 45 F (7 C).

Main Menu Features
Pretrip
A Pretrip Test verifies unit operation. This display allows a
Pretrip Test to be selected and initiated by the operator. If the
Pretrip Test is entered with the unit shut down a Full Pretrip
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. Test results are reported as PASS, CHECK or FAIL when the Pretrip Test is completed.
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.
Pretrip Test Considerations
When performing a Pretrip Test, the following issues should be considered.
• If running a Pretrip Test on a 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-4 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 trailer that has just been washed down, the extremely high humidity inside the trailer may result in false test results.
57
Operating Instructions
• If running a Pretrip Test on a trailer loaded with sensitive cargo, monitor the load temperature during the test as normal temperature control is suspended during pre-trip operation.
• Always perform Pretrip Tests with the trailer cargo doors closed to prevent false test failures.
Pretrip Test Sequence
Pretrip tests proceed in the order shown below. A Full Pretrip
Test is started with the engine or motor not running and 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.
• Zone 1 Cool Check - The ability of the unit to cool in low speed is checked.
• Zone 1 Heat Check - The ability of the unit to heat in low speed is checked.
• Zone 1 Return to Cool Check - The ability of the unit to return to cool mode is checked
• Zone 2 Cool Check - The ability of the unit to cool in low speed is checked.
• Zone 2 Heat Check - The ability of the unit to heat in low speed is checked.
• Zone 2 Return to Cool Check - The ability of the unit to return to cool mode is checked
• Zone 3 Cool Check - The ability of the unit to cool in low speed is checked.
• Zone 3 Heat Check - The ability of the unit to heat in low speed is checked.
• Zone 3 Return to Cool Check - The ability of the unit to return to cool mode is checked
58
Operating Instructions
• Report Test Results - When the Pretrip Test is completed the test results are reported as PASS, CHECK or FAIL. If test results are CHECK or FAIL alarm codes will exist to direct the technician to the source of the problem.
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.

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. The
TemperatureWatch screen is disabled if a Check Alarm is active.
70
Operating Instructions
Unit Level Check Alarms
If the alarm is unit specific, the Alarm Icon will appear at the
right side of the display as shown in Figure 79. Both Zone
Specific and Unit Specific Alarms can exist at the same time.
Figure 79: Alarm Icon
Zone Level Check Alarms
If the alarm is zone specific, the Alarm Icon will appear in the
offending zone as shown in Figure 80. An alarm exists in
Zone 2.
Unit Level Prevent Alarms
Prevent Alarms are also indicated by a steady alarm icon at the side of the display. 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 and then restart. If the unit is in a temporary shutdown, Alarm
Code 84 Restart Null will be present along with the associated
Prevent Alarm. In most cases the unit will restart with reduced performance to determine if continued operation is possible. If the alarm does not reoccur with reduced performance then the unit will then return to full performance. If the unit is operating with reduced performance Alarm Code 85 Forced Unit
Operation may also be present under some conditions. In general, if the alarm condition re-occurs a defined number of times then the alarm is set as a Shutdown Alarm and no further restarts are possible. The TemperatureWatch screen is disabled if a Unit Level Prevent Alarm is active.
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.

Operating Instructions
Zone Level Shutdown Alarms
A zone Shutd2own Alarm will force the affected zone to shutdown, but allow the unit to continue to run as required by the host unit or other zones. A small alarm icon will appear next to the affected zone and blink with a period of ½ second on - ½ second off. If zone Shutdown Alarms occur in all zones then the unit will shut down and Alarm Code 114 Multiple
Alarms - Can Not Run will be set.
Pretrip Alarms
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.

Loading and Enroute Inspections
This chapter describes pre-loading inspection procedures, single temperature loading procedures, post loading, and enroute inspection procedures for multi-temperature units.
Thermo King refrigeration units are designed to maintain the required product load temperature during transit. Follow these recommended loading and enroute procedures to help minimize temperature related problems.
NOTE: When in doubt as to the correct refrigeration requirements and/or loading procedures, call your company office for instructions.
Pre-Loading Inspection
1.
Make sure the unit is turned off before opening the doors to minimize frost accumulation on the evaporator coil and heat gain in the trailer. (Unit may be running when loading the trailer from a warehouse with door seals.)
2.
Spot check and record load temperature while loading.
Especially note any off-temperature product.
3.
Load the product so that there is adequate space for air circulation completely around the load. DO NOT block the evaporator inlets or outlets.
4.
Products should be pre-cooled before loading. Thermo
King transport refrigeration units are designed to maintain loads at the temperature at which they were loaded.
Transport refrigeration units are not designed to pull hot loads down to temperature.Verify that the setpoint temperatures are correct for your cargo. Pre-cool the trailer as required.
CAUTION: Cargo must be pre-cooled to the proper temperature before loading. The unit is designed to maintain temperature, not to bring a product to temperature.
CAUTION: Push the controller access door firmly closed after each use. Unit damage can occur in transit if the door is not properly closed.

Loading and Enroute Inspections
Single Temperature Loading
Procedures
Additional steps must be taken to insure load temperature requirements are implemented and maintained when a multi-temp unit is used to refrigerate a single-temperature load.
Trailer loading procedure will be different depending on how temperature control has established for each trailer compartment Zone. See “Operating the Unit in Single Zone
Mode” in the Operating Instructions chapter in this manual.
In the example in Figure 136, each Zone could be individually
set to 35 F. The evaporator in each compartment will then control the temperature in that compartment to the same 35 F setpoint.
NOTE: Using the above method, it is recommended that the bulkheads that separate each compartment be in place to isolate the compartments.
Figure 137 shows two Zones that have the same setpoint. The
bulkhead separating the compartments has been removed. The
Host evaporator senses temperature and controls both evaporators to the temperature setpoint.

111
Loading and Enroute Inspections
NOTE: Using Method 2, it is recommended that all bulkheads be removed to create one large compartment.
Post-Loading Inspection
1.
Make sure all the doors are closed and locked.
2.
Start the unit if it was shut off to load.
3.
Make sure the setpoints are at the desired settings.
4.
One-half hour after loading, manually initiate a Defrost cycle. If the evaporator coil sensor temperature is below
45 F (7 C), the unit will Defrost. The microprocessor will terminate Defrost automatically when the evaporator coil temperature reaches 58 F (14.5 C) or the unit has been in the Defrost mode for 30 or 45 minutes (depending on setting).
Post Trip Checks
1.
Wash the unit.
2.
Check for leaks.
3.
Check for loose or missing hardware.
4.
Check for physical damage to the unit.
Inspection Troubleshooting
1.
If a temperature reading is not within desired temperature range, refer to the troubleshooting table on the following pages. Correct problem as required.
2.
Repeat the Enroute Inspection every 30 minutes until the compartment temperature is within desired temperature range. Stop the unit if the compartment temperature is not within desired temperature range on two consecutive 30 minute inspections, especially if the compartment temperature appears to be moving away from the setpoint.
3.
Immediately contact the nearest Thermo King Service
Center or your company office.
4.
Take all necessary steps to protect and maintain proper load temperature.
CAUTION: Stop the unit if the compartment temperature remains more than 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.
112
Loading and Enroute Inspections
Inspection Troubleshooting
Problem
A return air temperature reading is not within desired temperature range of the setpoint.
Cause Remedy
The unit has not had time to cool down to correct temperature.
The unit may have a low refrigerant charge.
Refer to the load log history. Look for above temperature load records, properly pre-cooled cargo compartment, length of time on road, etc. Correct as required. Continue monitoring return air temperature until reading is within desired temperature range of the setpoint.
Check the receiver tank sight glass for refrigerant level. If liquid is not showing in the receiver tank sight glass, the refrigerant charge may be low.
A competent refrigeration technician is required to add refrigerant or repair the system. Contact the nearest Thermo King dealer, authorized Service
Center, or call the Thermo King Cold Line for referral. Consult the Table of
Contents for Cold Line information.
The unit is in defrost or has just completed a defrost cycle.
Monitor the return air temperature after the defrost cycle is completed to see if the temperature returns to the desired temperature range of the setpoint.
The evaporator is plugged with frost.
Initiate a manual defrost cycle. The defrost cycle will automatically terminate when complete. Continue monitoring return air temperature until reading is within desired temperature range of the setpoint.
113
Loading and Enroute Inspections
Problem
A return air temperature reading is not within desired temperature range of the setpoint
(continued)
Cause Remedy
Improper air circulation in the cargo compartment.
Inspect the unit and cargo compartment to determine if the evaporator fan(s) are working and properly circulating the air. Poor air circulation may be due to improper loading of the cargo, shifting of the load, or fan belt slippage.
Correct as required. Continue monitoring return air temperature until problem is corrected.
The unit did not start automatically.
Determine the cause for not starting. Correct as required. Continue monitoring return air temperature until reading is within desired temperature range of the setpoint.
The unit is being used to cool/heat a single temperature load and does not have the capacity to cool the entire trailer.
A multi-temperature unit may not have the cooling or heating capacity to maintain a specific temperature range throughout an entire trailer. Refer to
the “Single Temperature Loading Considerations” on page 111 for
instructions.
114
Alarm Codes
Introduction
An alarm code is generated when the microprocessor senses an abnormal condition. Alarms direct an operator or service technician to the source of a problem.
Multiple alarms can be present at one time. All generated alarms will be stored in memory until cleared by the operator.
Document all alarm occurrences and report them to the service technician.
See “Alarms Menu” in the Operation Instructions Chapter for information about viewing and clearing alarms.
NOTE: Some alarms (3, 4, 74, 203, and 204) cannot be cleared in the Alarms Menu, they must be cleared in the
Maintenance Menu or the Guarded Access Menu. Contact your supervisor or a Thermo King dealer about clearing those alarms.
IMPORTANT: Always record any Alarm Codes that occur - in the order that they occur - as well as any other pertinent information. This information is extremely valuable to service personnel.
NOTE: In some cases alarms cannot be cleared, or cannot be cleared after they have occurred a specified number of times.
If such is the case, these alarms must be cleared by service
personnel. See “Clearing Alarm Codes” on page 118.
Alarm Types
The four types of alarms are described below.
Log Alarms:
Log Alarms are indicated by the Log Alarms screen, which appears for approximately 30 seconds (just before the Standard Display appears) each time the unit is turned on. The Alarm Display must be used to view the existing alarms. This level of alarm serves as a notice to take corrective action before a problem becomes severe.
Maintenance items such as a maintenance reminder hour meter reaching its time limit are log alarms.

Check Alarms:
Check Alarms are indicated by the Alarm
Display in which the large Alarm Icon will appears on the
Standard Display as shown below in Figure 139. The Alarm
Menu must be used to view the existing alarms. 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.
Figure 139: Alarm Display
Prevent Alarms:
Prevent Alarms are also indicated by the
Alarm Display as shown in Figure 139. The Alarm Menu must
be used to view the existing alarms. The unit may stop running and wait a timed interval or until conditions allow and then restart. If the unit is waiting to restart, Alarm Code 84 Restart
Null will be present along with the Prevent Alarm. In other cases the unit may restart or run with reduced performance to determine if continued operation is possible. If the alarm does not reoccur with reduced performance the unit will then return to full performance. If the unit is operating with reduced performance Alarm Code 85 Forced Unit Operation will also be present.
116
Alarm Codes
Shutdown Alarms:
Shutdown Alarms are indicated by the
Alarm Display. Shutdown alarms also cause the display and backlight to flash on and off, and the display will switch from normal video to reverse video and back to normal video (light areas become dark and dark areas become light as shown in
Figure 140). Shutdown alarms force the unit into shutdown.
The unit will remain in shutdown and will not restart until the shutdown alarm is cleared. Exceptions are some engine and electric shutdown alarms become that log alarms when switched to the alternate operating mode (diesel to electric or electric to diesel).
If a shutdown alarm occurs that affects only Diesel Mode operation and the unit is switched to electric (either manually or automatically), 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 becomes a Diesel 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.
In the same manner, if a shutdown alarm occurs that affects only Electric Mode operation and the unit is switched to diesel
(either manually or automatically), 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.

Clearing Alarm Codes
Most alarm codes can be cleared conventionally from the
Alarm Menu using the CLEAR Key. See the Operating
Instructions chapter for procedures.
The operator should contact a supervisor or a Thermo King dealer about clearing alarms using the Guarded Access Menu.
Refer to the table on the following pages for alarm corrective action.
NOTE: Document all alarm faults and report them to the service technician.
There are three levels of corrective action that can be taken when an alarm condition occurs.
OK To Run:
An alarm condition exists but does not affect unit operation. Corrective action can occur at a later date.
Check As Specified:
An alarm condition exists that could affect unit operation. Follow directions in the Corrective
Action column on the following chart.
Take Immediate Action:
An alarm condition exists that will damage the unit or load. Take immediate action to correct the problem.
NOTE: The corrective actions listed in the Operating

Jump Starting
If the battery in a unit is discharged or run down, the unit may be jump started using jumper cables and another battery or vehicle. Consider the following precautions and be careful when jump starting a unit.
WARNING: A battery can be dangerous. A battery contains a flammable gas that can ignite or explode. A battery stores enough electricity to burn you if it discharges quickly. A battery contains battery acid that can burn you. Always wear goggles or safety glasses and personal protective equipment when working with a battery. If you get battery acid on you, immediately flush it with water and get medical attention.
CAUTION: Unhook the semi tractor from the trailer before using the tractor to jump start the unit on the trailer. The negative ground circuit is complete when the tractor is hooked to the trailer.
This can cause dangerous sparks when the positive connection is made at the battery.
IMPORTANT: Make sure to use a 12-volt battery to jump start the unit. If you are using a vehicle, make sure it has a
12-volt battery with a negative ground system. Do not use a
“hot shot” booster device or a 24-volt source.
Read and understand the following procedure completely before connecting any jumper cables. Use good jumper cables made with #2 gauge (or larger) cables.
1.
Make sure the unit is turned off. If you are using a vehicle, make sure its ignition is also turned off.
2.
Open the front doors on the unit. The battery is located to the right of the engine.
3.
Check the discharged battery to make sure it is not damaged or frozen. Do not jump start a damaged or frozen battery. Check the vent caps to make sure they are tight.
4.
Identify the positive (+) and negative (–) battery terminals.
5.
Remove the red cover from the positive (+) battery terminal on the unit’s battery.

6.
Connect the red positive (+) jumper cable to the positive
(+) battery terminal on the unit’s battery. Do not let the other end of the jumper cable touch anything that conducts electricity.
CAUTION: Allowing the positive (+) jumper cable to short can produce dangerous sparks.
7.
Connect the other end of the red positive (+) jumper cable to the positive (+) battery terminal on the good battery.
8.
Connect the black negative (–) jumper cable to the negative (–) battery terminal on the good battery. Do not let the other end of the jumper cable touch anything that conducts electricity.
9.
Connect the black negative (–) jumper cable to the lower starter mounting bolt on the unit’s engine.
10. If you are using a vehicle to jump start the unit, start the vehicle and let it run for a few minutes. This will help charge the discharged battery.
142
Jump Starting
CAUTION: Be careful around fans and belts.
Keep your hands away from moving parts when an engine is running.
11. Turn the unit on and let it start automatically or start it manually. If the unit will not crank or start, contact a qualified technician.
NOTE: Some units with microprocessors will show an alarm code and will not try to start until the battery voltage is above 10 volts.
12. After the unit starts, remove the jumper cables in reverse order: black negative (–) from the unit starter mounting bolt, black negative (–) from the good battery, red positive
(+) from the good battery, and red positive (+) from the unit battery (that was discharged).
