EMS Kontrol OXYGEN O₂ TRANSMITTER

WHAT IS IT?

The Oxygen Transmitter measures the oxygen value precisely and outputs it as an analog signal.

HOW DOES IT WORK?

It operates with a supply voltage between 12 V DC and 24 V DC. Measurement values are taken from the analog output terminals and transferred to the desired location.

RULES TO BE CONSIDERED FOR SAFETY

1. Always read the user manual before using the device and its apparatus.
2. Damages caused by opening, breaking, or misuse of the plastic parts of the device and its apparatus are considered out of warranty.
3. Keep the device and its apparatus away from external influences such as liquids, high dust, high temperatures, etc., and protect them.
4. Do not expose the device cables to any jamming or pressure.
5. Disconnect the electrical power when your device is not used for a long time.
6. EMS Kontrol devices and apparatus should be used by paying attention to the points in the user manual. In case of damages and malfunctions arising from external use (liquid contact, falling to the ground, etc.), ask for help from the service.
7. Failures due to electrical connection errors and electrical voltage or current errors are not covered by the warranty.

Technical Data

INSTALLATION

1. Unpack the product and open the top cover.
2. Make cable connections accordingly.

Wiring Diagrams:

• 0-10 V Wiring Diagram: Connect '+' and '-' terminals for O₂ input, 'GND' and '24 VDC' for power (12-24V DC).
• 4-20 mA Wiring Diagram: Connect '+' and '-' terminals for O₂ input, 'GND' and '24 VDC' for power (12-24V DC).
• Modbus RTU Wiring Diagram: Connect 'A' and 'B' terminals for O₂ communication, 'GND' and '24 VDC' for power (12-24V DC).

3. If the product will be mounted on the wall, use the screws and dowels provided in the package.
4. The product 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.
5. It is recommended to use a shielded cable as the communication cable to prevent communication signals from being affected by external influences.
6. Since the communication cable will create resistance, check the measurement values again after cable installation.

MODBUS RTU COMMUNICATION STRUCTURE

The default RS485 Baud rate for Modbus communication is 9600. Stop bit: 1, Parity: NONE. The default Slave ID is 85. The Oxygen value is stored in the holding register at address 2 (40003). Oxygen information can be obtained by reading these registers.

Slave ID and Baud rate can be changed via Modbus communication. To change the Slave ID, write the desired ID to the register at address 0 (40001). To change the Baud rate, write the value corresponding to the desired Baud rate from the table below to the register at address 1 (40002).

To reset changes made to the Slave ID or Baud rate to their default values, press and hold the "Calibration" button until the Status (green) LED turns off (approximately 30 seconds). After the LED turns off, release the button. This will restore the Slave ID and Baud rate to their default settings.

LED Meanings

BEFORE CALIBRATION

1. The product is sold calibrated. Please do not calibrate unless necessary.
2. Perform calibration only when it is certain that the product is measuring incorrectly.
3. Calibration is only carried out at the production facilities. Please contact EMS Kontrol for calibration.

SENSOR LIFE - IMPORTANT CRITERIA

1. Sensor life is 2 years. After 2 years, sensor replacement is required. Sensor replacement can be done easily in the area of use.
2. Do not expose the sensor to high volumes of natural gases, as it may cause the sensor to malfunction.
3. The sensor power connection must not be repeatedly switched on and off.
