ELEKTRIC ACTUATOR
M24-S, M230-S, M24-S-ST
INSTALLATION
Damper is delivered in closed position. When electric actuator is connected to the power
supply, damper blade will open. When the damper reaches the end position (damper
open), the electro motor will stop. Closing fire damper takes place automatically when a
power failure occurs. Thermal tripping device that comes with fire damper causes power
circuit break at a temperature of 72 °C. If checking is needed for proper functioning of
fire damper, pushing the switch on the thermal tripping device will close damper. When
switch on tripping device is released, the damper will open.
CONTROL
Damper can be opened without connecting to a voltage with enclosed handle by turning
it in the direction of the arrow on electric actuator (clockwise). Damper can be locked
in the desired position by fast turning handle a quarter of a turn (counterclockwise) for
Belimo BF, and by puling brake on Belimo BFL and BFN.
To unlock the electro motor, turn handle clockwise for a quarter of a turn for Belimo BF,
or release brake for Belimo BFL and BFN. After release, damper will be closed by return
spring. When damper is opened manually, electric actuator will not move the damper
into closed position in case of power failure.
