Process value (circular plug M8, continuation)

For line compensation reasons, connect sensor Pt-100 via three conductors. PIN3 and 4
must be bridged at the sensor.

NOTE

Termination connection for DeviceNet systems

On installing a DeviceNet system, it is important to have the correct termination circuit for the data lines.
The circuit avoids the occurrence of faults through signal reflections on the data lines. For this purpose
the main line is to be terminated at both ends with resistors of respectively 120

Ω and 1 / 4 W power

loss.

Actual process value for the fluid flow controller option (2 M8 round
plugs), or optionally: with temperature sensor input (3 M8 round
plugs)

* With external supply of the sensors the mass of the standard

signal must be connected with the mass of supply voltage.
