Functional description
The actuator opens or closes the damper blade.
Minimum and maximum positions can be set using mechanical stops.
1-wire control or 2-wire control (3-point) can be used.
1-wire control is actually an open/close control.
A spring return actuator moves the damper blade to the safe position in case of a power failure. Define the safe position with the order code: NC (normally closed) or NO (normally open). The spring return actuator is factory set according to the safe position.
The normal position of the damper blade is only achieved with 1-wire control (control voltage).
