Flow temperature with an active signal of DC 0…10 V = 0…100 °C:
Lower limit value: 0 °C
Upper limit value: 100 °C
With passive temperature sensors, the measured value can be readjusted by
−3.0…+3.0 K to compensate for line resistance. It is thus possible to make onsite
calibrations with a reference instrument.

When the Commissioning menu is quit, a check is made to see which sensors are
connected. If, later, one of the sensors connected at this point in time is missing, or if
there is a short-circuit, a fault status message […] sensor error will be delivered.
If there is an error on the measuring line, the operator unit will display the measured
value as follows:
• Open-circuit = ----
• Short-circuit =
oooo
Potential-free contacts for control functions can be connected to the digital inputs.

The input identifier can only be set for the configured inputs (display inputs and fault
inputs).
Fault inputs can also be configured to terminals that are already used. In that case, the
automatically set input identifier is always given priority.
The normal position can be predefined for each digital input.
