in case of a signal loss, a misinterpretation might be made for 0 – 20 mA, 0 – 5 V or 0 – 10 V, due
to the fact that E1 or E2 could take the value 0 mA even without loss of signal (end position CLOSED
= 0 mA or 0 V).

Adjustment in end positions
The setting described below applies to the standard positioner version, i.e. maximum
setpoint E1 (20 mA) triggers a travel to end position OPEN, minimum setpoint (0/4
mA) triggers a travel to end position CLOSED.
