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.
GBB/GIB13..1 / GBB/GIB33..1
Three-position
(see section 2.1 "Application")
-
Clockwise or counter-clockwise direction depends:
On the mode 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 angular rotation.
The switching points for auxiliary switches A and B can be set independent of each other in increments
-
Mounting two of the same actuator
types on the same damper shaft will
result in a double torque.(with
accessories ASK73.1)
The actuator can be manually adjusted by pressing the gear train disengagement button.
The angular rotation for the shaft adapter can be limited mechanically
by inserting the shaft adapter in 5° increments.
Rotary actuators without spring return GBB/GIB..1
Non-spring return actuators
GBB/GIB16..1
Modulating
Y = DC 0...35 V with
offset
Uo = 0...5 V and
DU = 2...30 V
span
·
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
·
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.
-
of 5° within 5° to 90°.
The actuator is equipped with an automatic switch-off mechanism.
Mounting two of the same
actuator types on the same
damper shaft will result in a
double torque.(with accessories
ASK73.2)
GIB161.1E/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.
