Information When changing the setting, a new label [5] indicating the set signal type must be
provided. Furthermore, the wiring diagram indicated on the name plate of the actuator
controls also changes.
10.6.2. Behaviour on loss of signal (actuator reaction)
In case of a loss of signal of setpoint E1 or actual value E2, the reaction of the actuator
can be programmed via switch [S2-7]. The complete selection range, however, is
only available for signals 4 – 20 mA.
The following reactions are possible:
Fail as is:
Actuator stops immediately and remains in this position.
Fail close:
Actuator moves the valve to end position CLOSED.
Fail open:
Actuator moves the valve to end position OPEN.
