3.3 Interfaces
The chlorine sensor with digital signal processing has a digital Modbus RTU interface (RS-485). The pin assignment has already
been explained in more detail in chapter 3.
The interface must be configured as follows:
• Baud rate: 9600 bps
• Data bits: 8
• Stop bits: 1
• Parity: none
• Flow control: none
A detailed description of the Modbus protocol commands can be found in the Annex.
3.4 Measurement
The sensor must be used for measurements in the flow cell type FLC (see chapter 4). The use of the sensor in other flow cells
must be approved by TriOS GmbH. Otherwise, no warranty will be given for the proper functioning of the sensor or for resulting
damage to property or personal injury.
The maximum permissible operating pressure of the sensor is 3.0 bar (with retaining ring). The permitted operating tempera-
ture of the sensor is 0...45 °C water temperature and 0...55 °C ambient temperature. The sensor may only be used to determine
and control the concentration of free chlorine.
As soon as the sensor is supplied with power, it starts measuring automatically. The measured values can be displayed, conver-
ted or stored using a TriOS controller.
Please also refer to the corresponding controller manuals! If the sensor is not recognized by the controller, the configuration of
the interface (see chapter 3.3) should be checked directly.
