Features
The brushless DC motor ensures accurate speed control, torque monitoring for protecting
the actuator and the damper, and provides a reliable failsafe function.
In the case of a power failure, the mechanical spring ensures the failsafe function.
Use
For the control of fire and smoke protection dampers.
● Nominal torque of 9 Nm for damper surfaces up to about 1.0 m
2
(friction dependent)
● In fire protection sections of plants where, in the event that the thermal fuse cuts out at a
duct or ambient temperature of 72 °C, or in the case of a power failure, the actuator must
travel travel to the failsafe position (zero position)
Functions
Control type Modulating control
Positioning signal,
with adjustable characteristic function
DC 0…35 V at
● Offset: Uo = DC 0...5 V
● Span: ∆U = 2…30 V
Direction of rotation Clockwise or counter-clockwise movement depends on the mounting
position of the damper shaft.
Spring return On power failure or when the operating voltage is switched off, the spring
return moves the actuator to its mechanical zero position.
Position indication: Mechanical Rotation angle position indication by using a position indicator.
Auxiliary switches The switching points for auxiliary switches A and B can be set independent
of each other in increments of 5…90°
Powerpack
(2 actuators, tandem mounted)
Not permitted.
Rotation angle limitation The rotation angle of the shaft adapter can be limited mechanically at
increments of 5°.
Technical design
Basic components
Housing Robust, lightweight all metal housing made from die-cast aluminium which
guarantees a long service life even under extreme environmental conditions.
Gear train Maintenance- and noise-free gear train with stall and overload protection for the life
of the actuator.
Spring preload The spring has a factory-set preload of 5° to ensure tight shutoff fort he fire and
smoke protection dampers.
Manual adjustment A hole with a screw in the center of the actuator allows manual setting of the gears.
A hex wrench is supplied.
Mounting bracket A perforated bracket with pin available, depending on the way the actuator is fixed.
Electrical connection The actuator comes with prewired 0.9 long connecting cables.
The actuators can be mounted on either side depending on the required direction of
rotation. All setting and operating elements are available on both sides of the actuator.
