Information For actuators equipped with positioner, it is possible to optionally select between
open-close duty (REMOTE OPEN-CLOSE) and modulating duty (REMOTE
SETPOINT). Selection is made via REMOTE MANUAL input, e.g. based on a 24 V
DC signal (refer to wiring diagram).
Behaviour in modulating duty for version with positioner:
In case of signal loss of setpoint E1 or actual value E2, the actuator moves to a
preset position. 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.
The behaviour on loss of signal can be set via a switch in the controls.
