Function of Normally Closed Version (NC)

  • When applying the operating voltage, the expansion system of the actuator will be heated. After passing the dead time a uniform procedure will follow.
  • When the voltage supply is cut off, the actuator will automatically close after passing the dead time due to calling of the expansion system.

Note: in case of any functional testing, be aware of the dead time behaviour and take this into consideration. The opening and closing ties will depend upon the ambient temperature.
