2 Non-spring return actuators
This chapter provides information on application, functions, and equipment
combinations. Furthermore, it contains a type summary and explains the actuator
design including setting and operating elements for this family of actuators.
2.1 Application
The actuators are used in ventilation and air conditioning plants to operate air dampers
and air throttles:
· For damper areas up to 4 m
2
, friction-dependent
· Suitable for modulating controllers (DC 0...10 V) or three-position controllers
(e.g. for outside air dampers)
· It is recommended to switch off the power during two-position control when the
actuator has reached the open or close position, in order to enhance life span and
reduce power consumption.
· For dampers having two actuators on the same damper shaft (tandem-mounted
actuators or Powerpack)
