Function
● The electropneumatic positioner, in combination with the drive, forms a regulation system. The current position of the drive is detected using a servo potentiometer and is sent back as actual value x. The actual and target values are simultaneously displayed
on the digital display.
● The setpoint w forms a current applied to the positioner, which in two-wire mode is also used to power the positioner. In 3- and 4-wire mode, power is supplied through a 24-V power input.
● The positioner works as a predictive five-point positioner, through whose output value ±Δy the integrated valves can be controlled by pulse length modulation. 

● These positioning signals cause pressure changes in the drive chamber(s) and thus a repositioning of the drive until the regulation deviation returns to zero. 

● Using three buttons and a digital display with the housing cover removed, operation (manual mode) and configuration (structuring, initialization, and parameterization) can be performed.
● By default, the basic unit has a binary input (BE1). This binary input can be individually configured and used e.g. to block the control levels.
● To be able to use the positioner in a variety of mechanically different rotational and linear actuators, it has a friction clutch and a switchable gear.
