External Position Detection; Installing Option Modules - Siemens SIPART PS2 Compact Operating Instructions

External position detection

WARNING
External position detection system
Versions with flameproof enclosures may not be operated with an external position detection system.
The aforementioned measures are not adequate in some applications. For example, continuous and strong vibrations, high
or too low ambient temperatures and nuclear radiation.
The position detection system and the control unit are mounted separately for these applications. A universal component is
available for this purpose. It is suitable for part-turn and linear actuators. You will require the following:
● An external position detection system with the order number C73451-A430-D78 comprising a positioner enclosure with
an integrated friction clutch, potentiometer as well as different blanking plugs and seals.
● Or a contactless explosion-proof non contacting system (e.g.6DR4004-6N).
● A positioner
● A three-pole cable to connect components.
● An EMC filter module with the order number C73451-A430–D23 is provided in a set along with cable clamps and M20
cable glands.
The EMC filter module is always used for the control unit whenever an external position detection system is used instead of
the internal position sensor. An external position detection system is, for example, a potentiometer with a 10 kΩ resistance
or a non contacting system.
