7.10 Changing the preset signal range for the set point
The positioning electronics can be preset using measurement points without the need for an input signal. For ad-
justment to the actuator, refer to chapter 7.5 Calibrating the positioning electronics to the travel.
Adjusting the 4...20 mA or 2...10 V signal
Conguration of DIP switches S1:
Figure 20: Set point 4-20mA, 2-10V
● Apply voltage to terminals 54 and 55 of the positioning electronics
● Measure the voltage between measurement points 3 and 6
● Use potentiometer P1 to adjust the voltage to 2.0 V
● Measure the voltage between measurement points 3 and 4
● Use potentiometer P2 to adjust the voltage to 10.0 V
Adjusting the 0...20 mA or 0...10 V signal
Conguration of DIP switches S1:
Figure 21: Set point 0-20mA, 0-10V
● Apply voltage to terminals 54 and 55 of the positioning electronics
