AUMA Electric multi-turn actuators SA 07.1 - 16.1_SAR 07.1 - 16.1 MATIC AM 01.1 - 02.1 - Manual (Page 38)

Prior to setting, it must be ensured that the circuit for the position
feedback E2 (see wiring diagram) is closed (measuring device or
link). In case of missing signal E2, the LED (V10) “E1/E2 < 4 mA”
(figure AE) is illuminated and the positioner shows no reaction.
21.2.1 Setting type of signal
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 AE).
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 ver-
sions, the positioner board is equipped with an additional switch S1-7.
