Air damper actuators
GIB13...1
GIB33...1
Rotary version three-position control
AC 24 V or AC 230 V
Electromotive rotary actuators for three-position control, nominal torque 35 Nm,
operating voltage AC 24 V or AC 230 V, for three-position control, span
mechanically adjustable between 0...90°, pre-wired with 0.9 m long connection
cables.
Type-specific variations with adjustable auxiliary switches for supplementary
functions and potentiometer for position indication.
To control air dampers in ventilating and air conditioning plants
•
using a nominal torque of 35 Nm for damper surfaces up to 6 m
2
, friction-dependent
•
Ideal with modulating three-position controllers or ON/OFF-controls (e.g., outside air
dampers, flue gas dampers, etc.)
The actuator's rotational movement (clockwise or counterclockwise) depends on the
electrical control.
As soon as the operating voltage AC 24 V or AC 230 V is applied, the actuator starts to
turn.
The connected damper can be operated as follows via the respective actuator control:
•
Damper opens (0°
⇒
90°)
•
Damper closes (90°
⇒
0°)
•
Damper remains in the current position
After uninterrupted runtime of approximately 200 s, the actuator turns off in the same
direction.
The position indicator located on the shaft adapter displays the rotational angle position
of the damper blade.
To manually adjust the actuator or the air dampers, the gear train must be disengaged
using the button PUSH". Refer to "Operating and setting elements" in the chapter
"Mechanical design".
