DIP 1 2 3 4 Actual value E2 Setpoint E1 E2 E1
0 – 5 V 4 – 20 mA Fail open Fail as is
0 – 5 V 4 – 20 mA Fail open Fail close
4 – 20 mA 0 – 20 mA
0 – 20 mA
0 – 5 V 0 – 20 mA
0 – 5 V
0 – 10 V
4 – 20 mA 0 – 20 mA
0 – 5 V Fail close
4 – 20 mA 0 – 20 mA
0 – 10 V Fail as is
0 – 20 mA
0 – 5 V 4 – 20 mA Fail open
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). 1)
10.6.3. 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.

End position CLOSED
1. Set selector switch to position Local control (LOCAL).
2. Move valve to end position CLOSED.
