Dimensions (units are in mm)
A. Bluetooth Adapter
B. QR code chip
C. TTL port for connection with controller
Procedure for adapter installation
- Detach the QR code chip from the Bluetooth Adapter by breaking. The QR code chip is used for pairing with mobile application.
- Attach the QR code chip to the door or any clean part of the cabinet that can be easily accessed for the pairing procedure.
- Secure the Bluetooth Adapter in a convenient location using double sided tape (Fig. 4-5) or by screw mounting (Fig. 6)
- Power off the controller by switching off the main supply to the controller.
5. Connect the Bluetooth Adapter to communication port of controller using interface cable (Fig. 7)
– TTL port in ERC21x and EETa
– DI port in ERC11x
Warnings/note:
- The installation of Bluetooth Adapter should be performed while the Cooler is switched off.
- Ensure the Bluetooth Adapter is installed away from heating source, direct sunlight, dripping water, dusty environment.
- Do not mount the adapter directly in food compartment in case of cold space installation.
- Avoid any obstruction around the adapter that impacts Bluetooth communication.
- Interface cable ordered separately for the respective controller to be used for connecting Bluetooth Adapter to Controller.
- Ensure that cables are always strain relieved and tied up by other means to cabinet.
Power up sequence and connection with mobile application:
| Function | Description | Illustration | LED info |
|---|---|---|---|
| Power-up | Power up the controller connected with Bluetooth Adapter. |
Bluetooth Adapter starts power up initialization (it gets power from connected
controller).| | •White – Blue – Red – Green LED blinking in sequence indicates
power up initialization.
•After few seconds, Green LED rapid flashes indicating controller detection is
in progress.
Established communication with controller and broadcasting.| After power up
initialization, the adapter establishes communication with connected
controller and start broadcasting.| | •Green LED slow flashes (1s/1s)
Unsuccessful identification/communication with controller.| | •Red LED rapid
flashes.
Connection with mobile app and Real time clock (RTC) update| Search and
connect broadcasting adapter using KoolConnect companion app. Click on “Set
time when mobile app shows alert message to synchronize the adapter time with
mobile time))| | •LED turns to constant Blue indicating Bluetooth is
connected.
- Note:
1. Ensure that the module is connected to the mobile app after final power up and installation to finalize the setup properly. If the module is not connected after final power up at customer’s site, the module will log the data without the correct time stamp.
2. If the Bluetooth Adapter is changed from one controller model to another (ex: ERC112C to ERC112D or EETa 3W), all the logged data from previous controller are erased and start logging afresh from new controller. The data from previous controller is retained if one code no. is changed to another code no. within the same controller model.
