6.2.2. Actuator operation from remote
→
Set selector switch to position Remote control (REMOTE).
➥
Now, it is possible to operate the actuator via remote control, via operation
commands (OPEN, STOP, CLOSE) or analogue setpoints (e.g. 0 – 20 mA).
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.
