Commissioning // TpH
3 Commissioning
This chapter deals with the commissioning of the sensor. Please pay particular attention to this section and follow the safety
precautions to protect the sensor from damage and yourself from injury.
Before the sensor is put into operation, it is important to ensure that it is securely attached and all connections are connected
correctly.
3.1 Electrical installation
3.1.1 Fixed Cable with M12 Industrial Plug
The sensor can be operated with 12...24 VDC.
1. RS-485 A
2. RS-485 B
3. Not assigned
4. Not assigned
5. Not assigned
6. Not assigned
7. Ground (Power + Ser. Interface)
8. Power 12...24 VDC
Ensure correct polarity of the supply voltage, because otherwise the sensor may be damaged.
The sensor is ready for commissioning as soon as the installation of accessories is complete, it is connected to your control
device and the conguration is complete.
3.2 Electric
3.2.1 Serial Interface
The serial interface of the sensor is RS-485 (9600/8-N-1).
With RS-485, voltages from -5 V to +5 V to ground are possible. RS-485 uses a dierential signal with the sign-negative potential
of the A line is put on the B line. The dierential value between lines A and B is the decisive factor for the transmission robust-
ness against conducted noise signals.
The protocol used is Modbus RTU. A detailed description of the Modbus RTU protocol for TpH can be found in the annex.
