8.15 Linking to an external pressure transducer
If the air system is operated with an air receiver, the pressure in the receiver can be regulated by
an external pressure transducer.
Transmitting a pressure transducer value
Assignment to an input
The external pressure transducer is connected to
SIGMA CONTROL 2.
AII assign
Pressure transducer characteristics:
■ 4–20 mA
■ 0–16.0 bar
Tab. 80 Transmitting a pressure transducer value
The controller processes the options in the following sequence:
■ Pressure according to the assigned external transducer
■ The local system pressure transducer (pNloc) remains active.
Overview
Example: The external pressure transducer is connected to SIGMA CONTROL 2.
