4.6 External position detection

4.6 External position detection
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 controller 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 article 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 article 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 controller unit whenever an external position
detection system is used instead of the internal sensor. An external position detection
system is, for example, a potentiometer with a 10 kΩ resistance or an NCS.
