Note: 

Using Belimo Damper Actuators: 

The actuators listed in this catalogue are intended for the 

operation of air dampers in HVAC systems. 

The damper actuator is not allowed to be used outside the 

specified field of application, especially in aircraft. 

• The enclosure of the actuator equipment may only be 

opened by the manufacturer. It contains no components 

which the user can replace or repair. 

• The device contains electrical and electronic components 

and is not allowed to be disposed of as household refuse. 

All locally valid regulations and requirements must be 

observed. 

Torque requirements: 

When 

calculating the torque required to operate dampers, 

it is essential to take into account all the data supplied by 

the damper manufacturer concerning cross sectional area, 

design, mounting and air flow condition.

Auxiliary switch adjustment 

Auxiliary switch adjustment for General Damper Actuators 

1. Press the pushbutton, manually operate the universal clamp to 

desired switch position. 

2. Turn switch pointer to the middle line.

3. When actuator moves clockwise (counter clockwise) to switch 

position, switch indicator passes the middle line counter clockwise 

(clockwise), the contact between S1 and S3 is disconnected 

(connected) and the contact between S1 and S2 is connected 

(disconnected). 

Note: The switching point should be about 5° from the mechanical 

end stops (1 short step on the scale).

Auxiliary switch adjustment for Mechanical Fail-Safe Damper Actuators 

LF..-S (Mounting side R); NFU-S2, SFU-S2, EFU..-S2 (Mounting side L) 

Starting point: Actuator in safe position 

Procedure 

Turn the knob of the auxiliary switch until the 

tip of the arrow is pointing to the required 

switching position (see right). Example: 

Switching point setting = 4 corresponds to 

40% angle of rotation. 

When the actuator runs to the operating 

position (ccw ), the switch knob will also 

rotate counter-clockwise (ccw ) and the 

auxiliary switch will operate as the tip of the 

arrow passes the scale zero (S1–S3 linked).
