    4. Connecting the sensor via RS485 to the controller DEGA UPA III/UDA III 1. Installation of wiring for RS485 Wiring must be done using bus topology and according to the RS485 principles. Maximum number of connected transmitters per controler channel is 16 (may be less depending on the configuration of the controller), while the total length of the connecting cable (electrical distance between the controller and the last transmitter) should not exceed 1200 meters.

    2. Gas detection The transmitter continuously measures the detected gas concentration in the atmoshpere and converts it's current value into a 4-20 mA signal or transmits it's value to the evaluation unit via DEGA protocol. 3. Malfunction If a malfunction of the electronics or the sensor is found during operation, the transmitter will continue transmitting via current loop 0,5mA.
