Mounting sets are available for use with butterfly

manual adjuster is held firm in this mode, there
is no transmission of power to the gear train.
When pushing the manual adjuster down (1), it
engages and the actuator can be manually
operated.
Stroke actuator: When turning the manual
adjuster in clockwise / counterclockwise
direction (2), the actuator's stem retracts /
extends.
Rotary actuator: The actuator spindle turns in
the same direction.
An overload protection prevents damage to the

Upon actuation and locking the slide switch, the
manual adjuster remains engaged.
When in this mode, do not turn the manual
adjuster.
When resetting the slide switch, the manual
adjuster returns to automatic mode.
