Description of functions for GEB...1

The functions are listed in a table and are assigned to the respective control types.
GEB13..1 / GEB33..1
Three-position control
-
Clockwise or counter-clockwise direction depends:
On the type of control.
With no power applied, the actuator
remains in the respective position.
Rotary angle position indication by using a position indicator.
Connecting the feedback
potentiometer to an external voltage
source results in voltage supply
proportional to the rotary angle.
-
The switching points for auxiliary switches A and B can be set independent of each other in
.-
Mounting two actuators of the same
type on the same damper shaft
doubles the torque.
The actuator can be manually adjusted by pushing the gear train disengagement button.
The rotary angle for the shaft adapter can be limited mechanically
Actuators without spring return GEB...1
GEB16..1
Modulating control.
Y = DC 0...35 V with
offset Uo = 0...5 V and
ΧU = 2...30 V
span
∂
On the direction of the DIL
rotary direction switch.
∂
On the positioning signal.
The actuator stays in the
position reached:
∂
If the positioning signal is
maintained at a constant
value.
∂
If the operating voltage is
interrupted.
∂
Position indicator: Output
voltage U = DC 0...10 V is
generated proportional to
the rotary angle.
∂
Only for GEB16..1:
The direction of action
(inverted or not inverted)
of output voltage U
depends on the rotary
direction of the DIL switch.
∂
The actuator automatically
determines the
mechanical end of range
for the rotational angle.
∂
The characteristic function
(Uo, ΧU) is mapped to the
determined rotary angle
range.
increments of 5° within 5° to 90°.
The actuator is equipped with an automatic switch-off
mechanism.
by inserting the shaft adapter in 5° increments.
GEB161.1E/MO
Modbus RTU
-
On the setting of the
respective parameter
By Modbus register value
When self-adaption is active,
the actuator automatically
detects mechanical end of the
rotary angle range.
Not permitted.
