2.3.2 Supplementary information on the description of
functions for GBB/GIB16..1
The following information applies to modulating actuators.
D
Offset Uo and span U can be adjusted using two potentiometers (see section 3.4
"Adjustable characteristic function"). The maximum permissible input voltage (Uo +
is DC 35 V.
Actuators featuring this function can be used for the following applications:
· Dampers with a rotary angle limitation, for instance in the 0°...45° range, can be
controlled using the full positioning signal range DC 0...10 V.
· As a sequencing actuator in control loops that can only apply a DC 0...10 V
positioning signal to control more than one sequence.
· In control systems with a positioning signal deviating from DC 0...10 V such as
DC 2...10 V or DC 0...35 V.
All process values (setpoints and actual values) and all parameters are implemented as
Modbus RTU registers.
The actuator automatically determines the effective rotary angle range when the
respective parameter is set to "on". In that case the actuator performs a calibration run
at first startup to determine its actual opening range and adjusts the 0..100% feedback
signal to this opening range.
The table shows the different effects of the characteristic function's mapping to the
rotary angle range for "inactive self-adaptation" and "active self-adaption":
Inactive self-adaption
· The actuator calibrates the position
indication with Actual Position =
0..100% for rotary angle = 90°

Controllers

The actuators can be connected to all controllers having the following outputs.
All safety-related requirements must be met (see chapter 4 "Engineering notes").
