Commissioning
3.3 Interfaces
The chlorine dioxide 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 1.0 bar (with retaining ring). The permissible temperature ope-
rating range of the sensor is 0 to <50 °C. The sensor may only be used to determine and control the chlorine dioxide concen-
tration.
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 should be checked directly (see chapter 3.3).
