Position recording
If the actuator is equipped with a signaling gear, position recording is performed via precision film potentiometer with microcontroller assessment.
The signaling gear reduces the revolutions required for travel to the permissible rotation angle of the precision film potentiometer.
For "non-intrusive – commissioning without opening the actuator" (without signaling gear), the position is recorded with utmost precision and is transmitted to the
microcontroller.
Positioner
Defining an analog position setpoint (0/4–20mA) for the positioner results in precise control of the position corresponding to this value.
The positioner works adaptively. This leads to a continuous automatic adaptation of the threshold value to the controlled system:
hysteresis 0.4% of the travel
response threshold (dead band) adjustable, default setting: 0.2 to 2.5 % of the travel
upward adaptation response threshold is enlarged by 0.1 %, if an OPEN ==> CLOSE ==> OPEN command sequence occurs within 6 seconds
downward adaptation response threshold is reduced by 0.01 %, when no control has taken place within 10.8 seconds
