The 

operating range

 is given by the overall resistance range of the feedback potentiometer. Defining the

control range places a maximum limit on the 

control range

 used.

IMPORTANT

• The servomotor must be actuated with the same care as for the calibration of a measuring

sensor.

• To ensure correct function, the control duration of the servomotor must be at least

25 seconds for 0...100 % of the control range.

NOTE

• When the wide bar is as far right as it will go, the servomotor is fully open.

• The permanent display shows to what degree the motor has opened in % (the greater the

percentage, the farther open the servomotor).
