2.10: 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.

2.11: 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 H.M.I. automatically initiates timed or demand defrost cycles. The H.M.I. can be programmed to initiate timed defrost cycles at intervals of 2, 4, 6, 8, or 12 hours. Demand defrost cycles occur if the 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. Refer to (Initiating a Manual Defrost Cycle).

Note The unit will not perform a Manual Defrost Cycle unless the unit has been turned on with the ON 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 7°C (45°F).

Note All truck and trailer units will have a small battery drain when the unit is off. The battery can be drained even quicker if there are Aftermarket options or third party devices connected to the unit which consume battery power.

This will cause the battery to become discharged over time.

Apart from the obvious inconvenience of having to charge the battery, it is also liable to damage battery cell material and cause the life of the battery to be shorter than acceptable.

Therefore, to ensure the battery remains in optimum condition during periods when the unit is not being used, Thermo King strongly recommends to switch on the unit at least once each week and run for 30 minutes or longer to keep the battery safe.

If the EnergyONE battery is drained after a long idle period, it will need to be recharged using an automatic programmable battery charger (Thermo King does not recommend the use of manual battery chargers on dry cell batteries).

Failure to do so may result in warranty for the battery being rejected.

Alternatively, Thermo King offer a solar panel option from aftermarket which would negate the requirement to switch off the microprocessor switch during long unit idle periods. For more information, please contact your local Thermo King dealership.

Compressor:

Important To maintain the integrity of the compressor shaft seal and to prevent loss of refrigerant, it is recommended to run the unit at least once each week for 30 minutes or longer.

Belts: Verify belts are in good condition and adjusted to the proper tension. For more information about belt tension, see the Specifications chapter.

Electrical: Check the electrical connections to verify they are securely fastened. Wires and terminals should be free of corrosion, cracks, and moisture.

Structural: Visually inspect the unit for leaks, loose or broken parts, and other damage.

Coils: Verify condenser and evaporator coils are clean and free of debris.

  • Washing with clean water should be sufficient.

  • The use of cleaning agents or detergents is strongly discouraged due to the possibility of degradation of the construction.

  • If using a power washer, the nozzle pressure should not exceed 600 psi (41 bar). For the best results, spray the coil perpendicular to the face of the coil. The spray nozzle should be kept between 1 inch and 3 inches (25 to 75 millimeters) from the coil surface.

  • If necessary to use a chemical cleaner or detergent, use a cleaner that does not contain any hydrofluoric acids and is between 7 and 8 on the pH scale. Verify dilution instructions provided by the detergent supplier are followed. In case of doubt about the compatibility of the detergent with the type of materials listed above, always ask the supplier a written confirmation of the compatibility.

  • Should a chemical cleaner be required, it is MANDATORY that all components are thoroughly rinsed with water even if the instructions of the cleaner specify that it is a “no rinse” cleaner.

    Notice
  • Equipment Damage
  • Failure to comply with above mentioned guidelines will lead to a shortened life of the equipment to an indeterminable degree and also may void your warranty.
Note The repeated transportation of meat and fish waste can cause extensive corrosion to the evaporator coils and evaporator section tubing over time due to ammonia formation and can reduce the lifespan of the coils. Appropriate additional measures should be taken to protect the coils against the aggressive corrosion that can result from transportation of such products.

Cargo Box: Check the interior and exterior of the cargo box for damage. Any damage to the walls or insulation must be repaired.

Note On trailers equipped with units qualified for pharmaceutical applications - under ThermoKing protocol inspect the integrity of the air chute.

Cargo Doors: Verify the cargo doors and weather seals are in good condition. The doors should latch securely and the weather seals should fit tightly.

Damper Door: The damper door in the evaporator air outlet must move freely with no sticking or binding.

Defrost Drains: Check the defrost drain hoses to verify they are open.

TracKing Module:

  • Check that the module is turned on and communicating.

  • For Whisper™ Pro Enabled TracKing, it is recommended to check at some stage throughout your journey if the SR-3 unit automatically switches to “High Speed Lock Out” in an area designated for this - i.e., PIEK assigned Zone.

Chapter 5: 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.

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

  1. Please refer to Profeesor Kool and the “TK Tutor Series” App for step by step instructions and training on Alarm types and how to clear alarms. Please refer to “TK Alarm Codes” App for the most up to date alarms list. These apps can be found at the following link: http://www.europe.thermoking.com/tools/

  2. 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.

  3. 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. These are all explained in your Alarm Codes App.

Chapter 6: Loading and Inspection Procedures

This chapter describes pre-loading inspections, loading procedures, post-loading procedures, post-loading inspections, and enroute inspections. 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.

6.1: Pre-Loading Inspection

  1. Pre-cool products before loading. Note any variances on the manifest.

  2. Inspect door seals and vent doors for condition and a tight seal with no air leakage.

  3. Inspect the trailer inside and out. Look for:

    • Damaged or loose trailer skin and insulation

    • Damaged walls, air ducts, floor channels, or “T” flooring

    • Clogged defrost drain tubes

    • Blocked return air bulkhead

  4. Verify that the setpoint temperature is correct for your cargo. Pre-cool the trailer as required.

  5. Supervise product loading to ensure sufficient air space around and through the load.

    Note If the warehouse is not refrigerated, operate the unit with the doors closed until cargo is ready to be loaded. Then turn off the unit, open the cargo doors and load cargo. When cargo is loaded, close trailer doors and restart the unit. The unit can be operated with the cargo box doors open if the truck is backed into a refrigerated warehouse and the dock door seals fit tightly around the trailer.

    Loading Considerations
    1. Correct load height (trailers without chutes) 6. Clear defrost drains
    2. Tight doors and seals 7. Good outside air circulation
    3. Good air circulation around load 8. Unit inspection
    4. Proper cargo temperature (prior to loading) 9. Tight seals
    5. Interior/exterior walls and insulation in good condition 10. Maximum load height followed

    6.2: Post-Loading Inspection

    Post-loading inspections verify the cargo has been loaded properly. To perform a post-load inspection:

    1. Inspect the evaporator outlets for blockage.

    2. Turn the unit off before opening the cargo box doors to maintain efficient operation.

      Note The unit can be operated with the cargo box doors open if the truck is backed into a refrigerated warehouse and the dock door seals fit tightly around the trailer.

    3. Perform a final check of the load temperature. If the load is above or below temperature, make a final notation on the manifest.

      Important Cargo must be pre-cooled to proper temperature before loading. The unit is designed to maintain temperature, not cool an above-temperature load.

    4. Close or supervise the closing of the cargo box doors. Verify they are securely locked.

    5. Verify the setpoint is at the temperature listed on the manifest.

    6. If the unit was stopped, restart using the correct starting procedure. See the Operating Instruction chapter in this manual.

    7. Start a manual defrost cycle 30 minutes after loading. See the Manual Defrost procedure in the manual.

    6.3: Enroute Inspections

    Complete the following enroute inspection every four hours. This will help minimize temperature related problems.

    Inspection Procedure

    1. Verify setpoint is correct.

    2. Check the return air temperature reading. It should be within the desired temperature range.

    3. Initiate a manual defrost cycle after each enroute inspection.

    Inspection Troubleshooting

    1. If a temperature reading is not within the desired temperature range, refer to the troubleshooting table ( Inspection Troubleshooting). Correct problem as required.

    2. Repeat the Enroute Inspection every 30 minutes until the compartment temperature is within the desired temperature range. Stop the unit if the compartment temperature is not within the 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 or FRIGOBLOCK Dealer or your company office.

    4. Take all necessary steps to protect and maintain proper load temperature.

        5. Notice
      • Cargo Loss
      • Stop the unit if the compartment temperature remains higher than the desired temperature range from the setpoint on two consecutive 30 minute inspections. Contact the nearest Thermo King or FRIGOBLOCK Dealer or your company office immediately. Take all necessary steps to protect and maintain proper load temperature.
    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. 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 the reading is within the desired temperature range of the setpoint.
    Note Ensure cargo is properly pre-cooled prior to loading onto trailer. If 'warm cargo' is loaded onto trailer and reefer is used to cool to setpoint this will result in longer time required to cool down to correct temperature and possibly plugging of evaporator with frost due to increased humidity in trailer compartment.
    The unit may have a low refrigerant charge. Check the receiver tank sight glass for refrigerant level. If fluid 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 dealer, authorized Service Center, or refer to Emergency Assistance section for contact 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 the return air temperature until the reading is within the desired temperature range of the setpoint.
    Improper air circulation in the cargo compartment. Inspect the unit and cargo compartment to determine if the evaporator fan (3) are working properly circulation the air. Poor air circulation may be due to improper loading of the cargo, shifting of the load, or depending on unit, fan belt slippage or faulty electrical fans. 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.
       

    Chapter 7: Connecting to a Third Party Device

    All SLXi trailer units come fitted as standard from factory with a Low Voltage Disconnect (LVD) switch to accommodate for 3rd party device connections. The LVD switch ensures that all SLXi units provide a dedicated device connection point for external devices, while also preventing battery discharge/depletion of the EnergyONE battery during unit idle periods.

    Important All external device connections must be connected through the LVD switch as per instructions detailed in the SLXi Installation Manual/External Device Connection with LVD (Click in the following location to download - www.emea-user-manuals.thermoking.com). Failure to connect external devices through the LVD switch may result controller and/or battery related failures being rejected by warranty. The LVD switch acts as a protective medium between the SLXi unit electrical system and external device(s).

    Connecting a Third Party Device

    LVD Switch

    The function of the LVD switch is as follows:

    • Disconnects power to external devices when battery voltage drops below 12.1V (for longer than five minutes).

    • Automatically resets when system voltage rises above 13V (for longer than 10 seconds).

    • Provides connection point in control box for up to three external devices.

    • Recommended total maximum current draw from all connected devices combined (At all times, not just when the unit is power down): 2 Amps.

      • Excessive current draw due to external devices when unit is powered down will result in the LVD switch disconnecting the output after a short period of time (possibly within hours - depending on total current draw).

    Chapter 8: Jump Starting

    If unit battery is discharged or run down, 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
    • Personal Protective Equipment (PPE) Required
    • 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
    • Hazard of Explosion
    • 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 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 and jumper cables. Use good jumper cables made with #2 gauge (or larger) cables.

    1. Verify unit is turned off. If you are using a vehicle, verify its ignition is also turned off.

    2. Open front doors on unit. Battery is located to the left of engine.

    3. Check discharged battery to verify it is not damaged or frozen. Do not jump start a damaged or frozen battery. Check vent caps to verify they are tight.

    4. Identify positive (+) and negative (–) battery terminals.

    5. Remove red cover from positive (+) battery terminal on the unit’s battery.

      Sequence for Connecting Jumper Cables
      1. Positive (+) Terminal on Unit Battery
      2. Positive (+) Terminal on Good Battery
      3. Negative (–)Terminal on Good Battery
      4. Starter Mounting Bolt on Unit Engine

    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.

        Warning
      • Hazard of Explosion
      • Allowing the positive (+) jumper cable to short to ground can produce dangerous sparks.

    1. Connect the other end of the red positive (+) jumper cable to the positive (+) battery terminal on the good battery.

    2. Connect the black negative (–) jumper cable to the negative (–) battery terminal on a good battery. Do not let the other end of the jumper cable touch anything that conducts electricity.

        Warning
      • Hazardous Voltage
      • DO NOT connect to the positive connection on the starter motor, which is located on the top right of the starter motor.

    3. Connect the black negative (–) jumper cable to the lower starter mounting bolt on the unit’s engine.

    4. 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.

        5. Danger
      • Risk of Injury
      • Keep your hands, clothing, and tools clear of fans and/or belts when working on a unit that is running or when opening or closing compressor service valves. Loose clothing might entangle moving pulleys or belts, causing serious injury or possible death.

    5. 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 the unit until battery voltage is above 10 volts.

    1. 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).

      Sequence for Disconnecting Jumper Cables
      1. Starter Mounting Bolt on Unit Engine
      2. Negative (–)Terminal on Good Battery
      3. Positive (+) Terminal on Good Battery
