2-point control signal 

continuous voltage

 is required at the valve for operation with a 2-point control signal. This 

causes the motor to be rotated 

clockwise

 into its end position. 

The 

Y control phase

 uses an integrated relay to switch the rotational direction to 

anti-

clockwise

 and the motor rotates to its other end position. If this 

Y control phase

 is switched 

off again, the motor rotates 

clockwise

 back to the other end position ("virtual return spring"). 

Normally, a wire jumper needs to be established from above across the neutral connection 
and the second terminal. 

No earth connection is required, because the drive unit is safety insulated. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

An 

external voltage

 may also be used for switching, if it cannot be ensured that the 

Y

 control 

phase has the same phase angle (L1, L2, L3) as the continuous phase or originates from the 
same electrical circuit:
