DANGER
!
Risk of electric shock from exposed live
parts.
Do not touch live parts on operating the
manual override.
1. Unscrew front cover and place a 4 mm
Allen key on the red actuating shaft.
NOTICE
!
Risk of damage to the actuator by turning it
too far.
Only retract the actuator stem as far as the
final travel value.
2. Turn the Allen key:
Î Turn it counterclockwise only for a ver-
sion with fail-safe action "actuator stem
extends".
Î Turn it clockwise only for a version with
fail-safe action "actuator stem retracts".
3. Turn the Allen key only as far as the final
travel value, which is at the point where
the torque-dependent limit switch is acti-
vated.
Once the magnet has been released, the
spring mechanism pushes the actuator
stem back to the fail-safe position.
4. Remove Allen key and carefully refasten
the front cover.
