3.4 Adjustable characteristic function
A modulating positioning signal DC 0..35 V from a controller drives the actuator. The
angular rotation is proportional to the positioning signal. Using potentiometer "Uo", you
can set the offset for DC 0...5 V, and with potentiometer "
D
U", you can set the span for
DC 2...30 V.

The Y input is limited to max. DC 35 V
·
The adjustable span
D
U is max. 30 V
Define the adjustable span
D
U if the actuator is to open from 0...50 % at a positioning
signal of Y = DC 2…10 V. The offset Uo thus amounts to 2 V. The angle of rotation is
90°.
