6.1 Emergency Manual Override

Assembly

1.   Pull the crank (1) out of the bracket
2.   Remove cover screw (2) with the provided crank (1)
3.   Insert the crank in the hexagon shaft in the opening

Function

Push the crank down to the stop. This activates a micro 
switch that disconnects the actuator from the current. When 
letting go the crank, the actuator is energized again.
With 9 revolutions, the actuator EA21 turns by 90°
With 27 revolutions the actuator EA31 turns by 90°
With 41 revolutions the actuator EA42 turns by 90°

Direction of rotation
Clockwise 

= CW 

= close

Counterclockwise 

= CCW  = open

 

Note the “open” and “closed” position on 
the optical indicator

 

Disconnect the connector plug.

 

If that is not possible, after usage pull the 
crank rapidly out of the opening. (Actuator 
might start turning)
