Description

Features
 

  • Mode of operation The actuator is controlled with a standard modulating signal of 2 ... 20 V phase cut and travels to the position defined by the control signal. Measuring voltage U serves for the electrical display of the damper position 0 ... 100% and as slave control signal for other actuators.

  • Parameterisable actuators The factory settings cover the most common applications. The output signal and other parameters can be altered with the MFT-H parameterising device or the BELIMO Service Tool, MFT-P.

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

  • Manual override Manual operation with self-resetting pushbutton possible (the gear is disengaged for as long as the button is pressed).

  • Adjustable angle of rotation Adjustable angle of rotation with mechanical end stops.

  • High functional reliability The actuator is overload-proof, requires no limit switches and automatically stops when the end stop is reached.

  • Home position When the supply voltage is switched on for the first time, i.e. at commissioning or after pressing the «gear disengagement» switch, the actuator travels to the home position.
