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 2.3) 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.

Manual control of the air dampers is possible by gear train disengagement (7)
when the VAV compact controller is disconnected from the power supply.
