Use
The rotary actuators are used in ventilation and air conditioning plants to regulate and shut
off air dampers:
● GDD..1E for damper areas up to 0.8 m
2
, GLD.1E for damper areas up to 1.2 m
2
(guide-
line, always observe damper manufacturer’s data).
● Suitable for use with modulating controllers (DC 0/2...10 V), open-close or three-position
controllers for air dampers or air throttles.
● We recommend a minimum pulse length of 500 ms on rotary actuators operated with
3-point control to ensure continuous and accurate operation.

Power supply
AC 24 V ~ / DC 24…48 V ⎓
Control type
Open-close / three-position
Modulating control (0/2…10 V)
Rotary direction
Clockwise or counter-clockwise direction depends …
… on the type of control
… on the setting of the rotary direction
switch.
With no power applied, the actuator
remains in the respective position.
… on the setting of the rotary direction DIL
switch
… on the positioning signal.
The actuator remains in the achieved
position:
… if the control signal is maintained at a
constant value
… for loss of operating voltage.
Position indication:
Mechanical
Rotary angle position indication by using a position indicator.
Position indication:
Electrical
Output voltage U = DC 0/2...10 V is
generated proportional to the rotary angle.
U depends on the rotary direction of the
DIL switch setting.
Auxiliary switch
The switching points for auxiliary switches A and B can be set independent of each
other in increments of 5° within 0° to 90°.
Manual adjustment
The actuator can be manually adjusted by pressing the gear train disengagement
button.
Rotary angle limitation
The rotary angle of the shaft adapter can be limited mechanically with a set screw.
Technical design
Housing
The housing consists essentially of flame retardant, non brominated, non chlorinated glass
fiber reinforced plastic.
Actuator motor / Gears
● Brushless, robust DC motors ensure reliable operation regardless of load. The damper
actuators do not require an end position switch, are overload proof, and remain in place
upon reaching the end stop.
● The gears are maintenance free and low noise.
