Mounting
The electric actuator must not be operated in manual mode with the hand wheel moving out of its
factory setting/swivel range. It is used a rotating potentiometer. By the gear ratio the zero point will
shift when turning over the working angel. If you have deadjusted the zero point, as long as the
actuator is to twist in the manual mode with 360 ° turns, until the measured value is the same as the
origin value. The potentiometer output signal is an ohmic value which varies in a range between 0 K
Ohm and the specified maximum value. The minimum and maximum value can not be shown,
caused by the design. It is simply a sector. The ohmic values can vary from actuator to actuator, for
the same position. Each actuator is individually to calibrate during installation and put into operation.
For the corresponding positions you can either tap the ascending or descending value of the
potentiometer.
The potentiometer must be specified in the order, as subsequent conversion is not possible.
The electric quarter turn actuator has two adjustable, potential- / volt- free signals for the position
confirmation.

The potentiometer output signal shows the actual position of the valve shafts. The signal is shown in
an ohmic value. This can be evaluated by an appropriate control and then processed. The following
three potentiometer values are available:
Reference
If it is desired that the actuator stops in intermediate positions without major effort, the model with
positioner DPS is to choose. The model is available in versions 0 - 10 V, 4 - 20 mA or 0 - 20 mA / Input
and output signal.
