Rotary version, three-position control,
AC 24 V or AC 230 V
Electromotive rotary actuators for three-position control, nominal torque 20 Nm,
operating voltage AC 24 V or AC 230 V, for three-position control, span
mechanically adjustable between 0...90°, pre-wired with 0.9 m long connection
cables.
Type-specific variations with adjustable auxiliary switches for supplementary
functions and potentiometer for position indication.
To control air dampers in ventilating and air conditioning plants
• using a nominal torque of 20 Nm for damper surfaces up to 4 m2, friction-dependent
• Ideal with modulating three-position controllers or ON/OFF-controls (e.g., outside air
dampers, flue gas dampers, etc.)
The actuator's rotational movement (clockwise or counterclockwise) depends on the
electrical control.
As soon as the operating voltage AC 24 V or AC 230 V is applied, the actuator starts to
turn.
The connected damper can be operated as follows via the respective actuator control:
• Damper opens (0° ⇒90°)
• Damper closes (90° ⇒0°)
• Damper remains in the current position
After uninterrupted runtime of approximately 200 s, the actuator turns off in the same
direction.

The position indicator located on the shaft adapter displays the rotational angle position
of the damper blade.
To manually adjust the actuator or the air dampers, the gear train must be disengaged
using the button PUSH". Refer to "Operating and setting elements" in the chapter
"Mechanical design".
The rotational angle of the shaft adapter can be limited to 5°increments between 0°
and 90°.
Auxiliary switches provide supplementary functions. The switching points for switches A
and B (one changeover switch each) can be set independently in increments of 5°within
the 0°...90°rotational angle.
Refer to "Technical design", "Commissioning notes" and "Internal diagram".
The integrated potentiometer can be connect to voltage as a positioner; refer to
"Technical data". The voltage applied is proportional to the actuator's rotational angle.

The basic system data for the control systems in use contains all engineering notes.
Read all the engineering notes before mounting, wiring, and commissioning the actuator
and pay special attention to all safety information.
These actuators must be used in a system only for applications as described in the
basic system data documents for the applied control systems. Additionally, all actuator
specific features and rules must be observed as described in the brief description on the
title page of this data sheet (bold print) and in the chapters "Use", "Engineering notes",
and "Technical data".
All paragraphs marked with the special warning triangle as illustrated on the left contain
additional safety information and limitations that must be observed under any
circumstances to avoid physical injuries or damages to equipment.
These actuators must only be used with safety extra-low voltage (SELV) or protection
by extra-low voltage (PELV) in accordance with HD 384.
The actuators are double-insulated and do not provide a connection for the protective
ground.
Use either line voltage or safety extra-low voltage for auxiliary switches A and B. Do
not mix the two for operation. Howerver, operation using various phases is permissible.
Do not open the actuator!
The actuator is maintenance-free. Maintenance work may only be conducted by the
manufacturer.
• Electric: Electric parallel connection for the same actuator types is permissible
provided the operating voltage is within the required tolerance. Voltage drops at the
feed lines must be included. Electric parallel connection of these actuators is possible
only via relay if used with types GDB..3..1, GLB..3..1, SQE...1 or SQR...1.
• Mechanical: Do not mechanically couple the actuators.
The quantity of actuators required depends on several torque factors. After obtaining
the damper torque rating (Nm/m2) from the manufacturer and determining the damper
area, calculate the torque required to move the damper as follows:
Total Torque = Torque Rating ×Damper Area
Number of actuators = Total Damper Torque required
SF x Actuator Torque (Refer to Specifications)
1
1Safety Factor: When calculating the number of actuators required, a safety factor should be included for
unaccountable variables such as slight misalignments, aging of the damper, etc. A suggested safety factor
is 0.80 (or 80% of the rated torque).
If the calculated number of actuators is greater than 1,
• the actuator type GIB…1E must be used
• or the damper construction must be adjusted accordingly
• Use safety insulating transformers with double insulation in accordance with
EN 60 742; the transformers must be made for 100% runtime.
• Observe all local safety rules and regulations pertaining to sizing and protecting
transformers.
• Determine the transformer’s power consumption by adding the power consumption
in VA for all actuators used.
Refer to "Commissioning notes" and "Internal diagram" in this data sheet as well as to
the HVAC job drawings.

All information and steps to properly prepare and mount the actuator are listed in the
Mounting Instruction guide M4626 delivered with the actuator. The shaft adapter as well
as all other individual parts are not pre-mounted as the actuator components are put
together differently depending the damper shaft length. Refer to "Mechanical design" in
this data sheet.
Select the mounting position so that you can easily access the cables as well as the
setting dials on the front of the actuator. Refer to "Dimensions".
In order to satisfy the requirements as per IP54, the following mounting conditions must
be fulfilled:
• Mount the actuators only vertically (cabling see below) for air dampers with horizontal
shafts.
• When the actuator is mounted directly on the damper shaft, the mounting angle my be
a maximum of +/- 45 °.
• Use the ASK75.1 weather shield for mounting in any other position.
If you mount the actuator directly on the damper shaft, the mounting bracket must be
used. The insertion depth for the shaft into the housing must be sufficient and
guaranteed.
Information on minimum length and diameter for the damper shaft is listed in "Technical
data".
The actuator comes with a factory setting of + 2 mm which ensures a tight close-off for
the air dampers.
To ensure a tight close-off function for the dampers and the exact switching position for
switches A and B, the actuator can only be adjusted with a mounted shaft adapter and
position indicator in accordance with the mounting instructions.
If necessary, you can limit the rotational angle in increments of 5°for the entire span by
positioning the shaft adapter in the respective position.
The mounting sets which are used to change the rotational movement into a linear
stroke as described in "Type summary" are mounted separately.
All information necessary for commissioning is contained in the following:
• This data sheet 4626
• Mounting instructions M4626
• Job diagram
Check to ensure that all permissible values as contained in "Technical data" are
observed.
• Check for proper mounting and to ensure that all mechanical settings are in
accordance with the plant-specific requirements. Additionally, ensure that the
dampers are shut tight when in the closed position.
• Fasten the actuator securely to avoid side load.
• Check the rotation direction: The dampers must be able to be moved by pushing the
button "PUSH".
• Check to ensure that the cables are connected in accordance with the plant wiring
diagram (see "Diagrams").
• The operating voltage AC 24 V (SELV/PELV) or AC 230 V must be within the
tolerance values.
