Installation
- Unpack the product and open the top cover.
- Make cable connections accordingly.
- If the product will be mounted on the wall, you can use the screws and dowels in the package.
- It starts measuring 30 seconds after the product is energized. It is recommended that the product remains in the environment for at least 5 minutes to get healthy measurement values.
- It is recommended to use shielded cable as communication cable as it will prevent communication signals from being affected by external influences.
- Since the communication cable will create resistance, check the measurement values again after cable installation.
Modbus RTU Communication Structure
Slave ID and Baud rate can be changed via Modbus communication. For this, the desired Slave ID is written to the register with address 0 (40001), where the Slave ID is located. Likewise, if the Baud rate is to be changed, the Baud rate can be changed by writing the value for the desired Baud rate according to the table below in the register with address 1 (40002).
Press and hold the "Calibration" button to reset the changes made to the Slave ID or Baud rate to the default values. Wait until the Status (green) LED turns off (approx. 30 seconds). After the LED turns off, the button is released. Thus, Slave ID and Baud rate are returned to their default values.
| Min. Value | Max. Value | Slave ID and Baud Rate Value |
|---|---|---|
| 1 | 0 | 1200 |
| 2 | 4800 | |
| 3 | 9600 | |
| 4 | 14400 | |
| 5 | 19200 | |
| 6 | 38400 | |
| 7 | 57600 | |
| 8 | 115200 |
LED Meanings
| Power (Red) | Measurement Status (Green) | |
|---|---|---|
| Normal Operating | On | On |
| No Energy (Error) | Off | Off |
| Preparation | On | Off |
| Normal | On | On |
| Error - Fault | On | Off |
Before Calibration
- The product is sold as calibrated. Please do not calibrate unless necessary.
- Perform calibration only when it is certain that the product is measuring incorrectly.
- Compare the measurement value of the device with another device or with a clean and open air control.
- If the device measures values outside the range of 350 ppm - 450 ppm in clean and open air, calibration can be performed.
Calibration
- A clean and open area away from any carbon dioxide source should be selected for carbon dioxide calibration.
- The amount of carbon dioxide in clean and open area varies between 350 ppm - 450 ppm. When calibration is done, the product takes the value at the time of calibration as 400 ppm.
- When the "Calibration" button in the product is pressed, the Status (green) LED starts blinking. When the LED is fully lit (approx. 10 seconds), the calibration process starts if the button is released. The Status LED starts blinking rapidly. When the blinking process is over, the calibration process is completed.
