Design and device parts
2.2.1 Design
The VAV compact controllers consist of a differential pressure sensor, actuator and
digitally configurable control electronics. They are intended for mounting on damper
shafts of a minimum length of 30 mm. They consist of base and 2-sectional housing.
Components contained in the
base
:
Steel base plate with damper drive shaft fixing for different drive shaft
diameters / cross-sectional areas (cf. section
) and angular rotation limiter,
maintenance-free, low-noise gear train,
magnetic hysteresis clutch with practically contact-free force transmission; this
means that the actuator is locking- and overload-proof.
Components contained in the
housing
(Note: Housing cover must not be removed):
Controller electronics,
differential pressure sensor, and
synchronous motor for the damper actuator.
