Wiring Diagrams
0-10 V / 4-20 mA Wiring:
- Terminal A: CO₂ Signal Output and GND.
- Terminal B: 24 VDC Power Input.
Modbus RTU Wiring:
- Terminal A: RS485 Data (+).
- Terminal B: RS485 Data (-).
- Terminal C: 24 VDC Power Input (+ and -).
Installation
- Unpack the product and open the top cover.
- Make cable connections accordingly.
- If the product will be mounted on the wall, use the screws and dowels provided in the package.
- The device starts measuring 30 seconds after being energized. It is recommended that the product remains in the environment for at least 5 minutes to obtain stable measurement values.
- It is recommended to use shielded cable as the communication cable to prevent communication signals from being affected by external influences.
- Since the communication cable will create resistance, check the measurement values again after cable installation.
LED Meanings
LED | Status | Meaning |
---|---|---|
Power (Red) | On | Normal Operation |
Power (Red) | Off | No Power / Error |
Status (Green) | On | Measurement in Progress / Normal |
Status (Green) | Off | Preparation / Idle |
Status (Green) | Blinking | Calibration Active |
Status (Green) | Rapid Blinking | Calibration Process Started |
Modbus RTU Communication Structure
The RS485 Baud rate in Modbus communication is 9600 by default. Stop bit: 1, Parity: NONE. Default Slave ID is 83. The Carbon Dioxide value is stored in the holding register at address 2 (40003). Carbon Dioxide information can be obtained by reading these registers.
Register Map and Default Values:
Register Address | Default Value | Read/Write | Min. Value | Max. Value |
---|---|---|---|---|
Slave ID 0 (40001) | 83 | R/W | 1 | 247 |
Baud rate 1 (40002) | 3 | R/W | 0 | 8 |
CO2 Value 2 (40003) | - | R | - | - |
Slave ID and Baud rate can be changed via Modbus communication. To change the Slave ID, write the desired value to the register with address 0 (40001). To change the Baud rate, write the value for the desired Baud rate according to the table below into the register with address 1 (40002).
Baud Rate Settings:
Min. Value | Max. Value |
---|---|
0 (1200) | 8 (115200) |
1 (2400) | |
2 (4800) | |
3 (9600) | |
4 (14400) | |
5 (19200) | |
6 (38400) | |
7 (57600) |
Press and hold the "Calibration" button to reset changes made to the Slave ID or Baud rate to their default values. Wait until the Status (green) LED turns off (approximately 30 seconds). After the LED turns off, release the button. The Slave ID and Baud rate will be returned to their default values.
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 environment for control.
- If the device measures values outside the range of 350 ppm - 450 ppm in clean and open air, calibration can be performed.
Calibration
- Select a clean and open area away from any carbon dioxide source for calibration.
- The amount of carbon dioxide in clean and open air varies between 350 ppm - 450 ppm. When calibration is done, the product sets the value at the time of calibration to 400 ppm.
- When the "Calibration" button on the product is pressed, the Status (green) LED starts blinking. Release the button when the LED is fully lit (approximately 10 seconds) to start the calibration process. The Status LED will then blink rapidly. The calibration process is completed when the blinking stops.
