2.3 Description of functions
2.3.1 Description of functions for GBB/GIB..1
The functions are listed in a table and are assigned to the respective modes of control.
Type
GBB/GIB13..1 / GBB/GIB33..1 GBB/GIB16..1 GIB161.1E/MO
Mode of control
Three-position
(see section 2.1 “Application”)
Modulating Modbus RTU
Positioning signal with
adjustable characteristic
function
-
Y = DC 0...35 V with
offset Uo = 0...5 V and
span
D
U = 2...30 V
-
Rotary movement,
direction of rotation
Clockwise or counter-clockwise direction depends:
On the mode of control.
With no power applied, the actuator
remains in the respective position.
·
On the position of the 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 supply voltage is
interrupted
On the setting of the respective
parameter
Position indication:
Mechanically
Rotary angle position indication by using a position indicator.
Position indication:
Electrically
Connecting the feedback
potentiometer to an external voltage
source results in voltage supply
proportional to the angular rotation.
·
Position indicator: Output
voltage
U = DC 0...10 V is
generated proportional to
the angular rotation.
·
The direction of action
(inverted or not inverted) of
output voltage U depends
on the position of the rotary
direction switch.
By Modbus register value
Self-adaptation of rotary
angle range
-
When self-adaption is active,
the actuator automatically
detects mechanical end of the
rotary angle range.
Auxiliary switches
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)
Mounting two of the same actuator
types on the same damper shaft will
result in a double torque.(with
accessories ASK73.1) Mounting two of the same
actuator types on the same
damper shaft will result in a
double torque.(with accessories
ASK73.2) Not permitted.
Manual adjustment The actuator can be manually adjusted by pressing the gear train disengagement button.
Limitation of angular rotation
The angular rotation for the shaft adapter can be limited mechanically
by inserting the shaft adapter in 5° increments.
