AUMA SA 07.1 - SA 30.1 - Setting Type of Signal

21.2.1 Setting type of signal (option)
The signal type (current/voltage signal) of nominal value E1 and actual
value E2 is set in the factory and marked with a label on the cover plate of
the positioner (refer to figure 47).
For split range version (page 38) and for versions with a setpoint
E1 ≠ 0/4 – 20 mA, it is possible to change the type of signalling. For these
versions, the positioner board is equipped with an additional switch S1-7:
If the setting is subject to subsequent change, the marking also has to be
changed. Furthermore, the wiring diagram indicated on the name plate of
the actuator controls also changes (see page 56).
