Important Information Before starting the installation, be aware of the following requirements: 1. The Thermo King wireless sensors advertise information via Bluetooth low energy. It is required to have a Thermo King telematics device (i.e TK BlueBox) which will receive the information. 2. Make sure that the vehicle is active in TracKing before installing the sensor. 3. Make sure that the application version is TK Technician Alpha Release V13.apk or above. 4.
Installation Best Practices I m p o r t a n t : BEFORE beginning the installation disconnect all power to the refrigeration unit including standby power (if equipped). • Familiarize yourself with the components to be installed. • Plan the layout and wire routing prior to permanently mounting any components. • Make sure wire routes are free from abrasive materials and have adequate clearance from hot surfaces.
Wireless Sensor Activation using TK Technician Application Activation of Temperature and Humidity Sensor, and Door Sensor in SLXi/A-Series 1. Open the TK Technician Application & click on the "WIRELESS SENSORS" option. N o t e : Make sure that the BlueBox is powered (LEDs on).
2. Enter or scan the reefer serial number or enter the TK BlueBox phone number using the TK technician application. 3. Click on the "GET DETAILS" option.
4. Scan the QR code on the rear side of the sensor to capture the Mac address. 5. Once application retrieves the data from the sensor, enter the sensor name, zone and position of the sensor, and then click on the “CONFIRM” to add the sensor to the bottom. 6. When all temperature and door sensors are confirmed, then click on “ACTIVATE”. N o t e : Make sure that the installer is near to the BlueBox at this moment.
7. If the Bluetooth activation is correct, you will receive a message at the bottom of the phone. 8. The temperature and humidity sensor, and door sensor are well installed and activated now.
Mounting Locations for Temperature/Humidity Sensor The temperature and humidity sensor shall be mounted under the roof, at the Return Air Grille (RAG) or Discharge Air Grille (DAG) positions inside the refrigerated compartment. N o t e : For installation at return air or discharge air, bracket is not required and the sensor can be tied with tie wraps. Use sensor PN 425484.
Temperature and Humidity Sensor Installation Installing the sensor under the roof: 1. Install the sensor on the bracket using screws.
2. Locate the sensor mounting position on the roof. Refer the below illustration for the recommended position and direction from the host. N o t e : Always Install the sensor on the left side of roof to avoid the interference with forklifts. N o t e : Make sure that the sensor is facing towards the reefer. This is important to ensure the signal reaches the TK BlueBox when the trailer is loaded.
3. Mark the mounting holes position of the sensor bracket. 4. Drill the pilot holes on the roof. 5. Install the bracket assembly to the roof using screws.
Door Sensor Installation N o t e : For proper operation, there must be no metal item(s) between the sensor and magnet. 1. Locate the magnet mounting position on the door. 2. Mark the holes position of the sensor magnet on the door. N o t e : Use the provided template to make sure the distance between the sensor and the magnet is appropriate. 3. Drill the pilot holes on the doors. 4. Install the magnet on the door using screws.
5. Locate the sensor mounting position on the roof. 6. Mark the holes position of the sensor on the roof. N o t e : Make sure that the magnet is align with the sensor. 7. Drill the pilot holes on the roof. 8. Install the bracket & sensor assembly on the roof using screws 9. Test the door sensor is reporting correctly door open and door closed.

Troubleshooting 1. Application Diagnostic Menu N o t e : This functionality is only usable with android phones. IOS filters the MAC address of the sensor so it is recommended to use android phones. a. Open the TK Technician Application & click on the "DIAGNOSTIC" option. b. Enter the reefer serial number or the TK BlueBox phone number and click “GET DETAILS” option.
c. The application will retrieve the sensors associated to the TK BlueBox. 2. To edit a temperature and humidity sensor or door sensor a. Open the TK Technician Application & click on the "DIAGNOSTIC" option.
b. Enter the reefer serial number or TK bluebox phone number and click on “GET DETAILS”. c. Slide the sensor from RIGHT to LEFT direction to select the EDIT option. d. Update the sensor information: name, position etc. and click on the ACTIVATE.
e. The “Bluetooth Configuration” message will indicate the sensor is being updated. 3. If the application does not recognize the serial number of the unit a. If you get the message, “it cannot detect the serial number of the unit in TracKing”, Please enter the phone number of the BlueBox, starting +353xxxxxxx.
4. If the label of sensor is damaged, to generate the QR code to scan using TK Technician Application a. Open online QR generator website in the laptop. b. Enter MAC ADDRESS + SPACE + SERIAL NUMBER to generate the QR code. c. Scan the generated OR code using TK Technician Application.
Battery Replacement 1. To replace the sensor battery N o t e : The door and temperature sensors use battery TK PN 2030998 / CR3677X. This special battery is qualified to work at temperatures from -40ºC to 85ºC. See images to understand how to replace the battery. • Remove the label (1). • Remove the screws (2). • Replace the battery. • Torque the screws to xx N.m. • Dispose the used battery in a suitable container.
