3.1 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.
3.2 Structure
3.2.1 Overview of structure
The following chapters describe the mechanical and electrical structure, components, and
principle functionality of the positioner.
The positioner is available in the following configurations:
● SIPART PS2 without explosion protection in metal or plastic housing
● SIPART PS2 with EEx ia/ib protection in metal or plastic housing
● SIPART PS2 with EEx d protection in explosion-proof housing
