Switch on operating voltage:

  • Actuator opens (counter-clockwise)

Switch off operating voltage:

  • Actuator closes with spring return (clockwise)

Positioning signal on Y1

  • – rotation counter-clockwise
  • – ball valve opens

Positioning signal on Y2

  • – rotation clockwise
  • – ball valve closes

0…10 V "counter-clockwise"
Flow = 0% at Y = 0 V
Flow = 100% at Y = 0 V

 

See mounting instructions M4659 for other switchings.

Emergency position
(Spring return)

On power failure or when the operating voltage is switched off, the spring moves the rotary actuator to its mechanical zero position.

Position indication:
Mechanical

Rotary angle position indication with manual lever as position indicator.1)

1)Using the position indicator as a manual lever can lead to damage to the gear.
