Features

 

  • Mode of operation The actuator moves the damper to the operating position at the same time as tensioning the return spring. The damper is turned back to the emergency position by spring force if the supply voltage is interrupted.

  • Pre-charging time (start up) The capacitor actuators require a pre-charging time. This time is used for charging the capacitors up to a usable voltage level. This ensures that, in the event of an electricity interruption, the actuator can be moved at any time from its current position into the preset emergency setting position (POP).
    The duration of the pre-charging time depends mainly on how long the power was interrupted.

  • Simple direct mounting Simple direct mounting on the damper spindle with a universal spindle clamp, supplied with ananti-rotation strap to prevent the
    actuator from rotating.

  • Delivery condition (capacitors) The actuator is completely discharged after delivery from the factory, which is why the actuator requires approximately 20 s pre-charging time before initial commissioning in order to bring the capacitors up to the required voltage level.
     
  • Parameterisable actuators The factory settings cover the most common applications. Input and output signals and other parameters can be altered with the BELIMO service tool MFT-P or with the ZTH-GEN adjustment and diagnostic tool.

  • Manual override Manual operation of the damper with the hand crank, locking in any position with the interlocking switch.
     
  • High operational reliability The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.

  • Home position / Start The spindle clamp of the actuator is set ex-works to 0°. eingestellt.
    After the supply voltage has been applied, the actuator moves into the selected position.

  • Direction of rotation switch When actuated, the direction of rotation switch changes the running direction in normal operation.
    The direction of rotation switch has no influence on the emergency setting position (POP) which has been set.

  • Emergency setting position (POP)rotary button The «Emergency setting position» rotary button can be used to adjust the desired emergency setting position (POP). The POP range is in reference to the maximum angle of rotation of the actuator.
    The rotary button is always in reference to an angle of rotation of 95° and does not take into consideration any end stops which were set retroactively.
    In the event of an voltage interruption, the actuator will move into the selected emergency setting position, taking into account the bridging time (PF) of 2 s which was set ex-works.

  • Bridging time (PF) Voltage interruptions can be bridged up to a maximum of 10 s.In the event of a voltage interruption, the actuator will remain stationary in accordance with the set bridging time. If the voltage interruption is greater than the set bridging time, then the actuator will move into the selected emergency setting position (POP).

    The bridging time set ex-works is 2 s. This can be modified at the site of operations with the use of the BELIMO service tool MFT-P.
  • Settings The rotary button must not be set to the «Tool» position!Only the values need to be entered for retroactive adjustments of the bridging time with the BELIMO service tool MFT-P.
