2.3 Description of functions
2.3.1 Description of functions for GEB...1
The functions are listed in a table and are assigned to the respective control types.
Type
GEB13..1 / GEB33..1
GEB16..1
GEB161.1E/MO
Control type
Three-position control
Modulating control.
Modbus RTU
Positioning signal with adjustable
characteristic function
-
Y = DC 0...35 V with
offset Uo = 0...5 V and
span
Χ
U = 2...30 V
-
Rotary movement,
rotary direction
Clockwise or counter-clockwise direction depends:
On the type of control.
With no power applied, the actuator
remains in the respective position.
∂
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.
On the setting of the
respective parameter
Position indication:
Mechanical
Rotary angle position indication by using a position indicator.
Position indication:
Electrical
Connecting the feedback
potentiometer to an external voltage
source results in voltage supply
proportional to the rotary angle.
∂
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.
By Modbus register value
Self-adaptation of rotary angle
range
-
∂
The actuator automatically
determines the
mechanical end of range
for the rotational angle.
∂
The characteristic function
(Uo,
Χ
U) is mapped to the
determined rotary angle
range.
When self-adaption is active,
the actuator automatically
detects mechanical end of the
rotary angle range.
Auxiliary switch
The switching points for auxiliary switches A and B can be set independent of each other in
increments of 5° within 5° to 90°.
Response on damper blocking
.-
The actuator is equipped with an automatic switch-off
mechanism.
Powerpack (two actuators,
tandem-mounted)
Mounting two actuators of the same
type on the same damper shaft
doubles the torque.
Not permitted.
Manual adjustment
The actuator can be manually adjusted by pushing the gear train disengagement button.
Rotary angle limitation
The rotary angle for the shaft adapter can be limited mechanically
by inserting the shaft adapter in 5° increments.
