3.6 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 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.
3.7 Installing option modules
A number of option modules are provided for the positioner. Different option modules are available depending on the version
of the device. Only the available option modules are listed below.
For additional information and the corresponding safety notes to be observed when installing the option modules, refer to the
detailed operating instructions for your respective device version.
Option modules in standard and intrinsically safe versions
The following option modules are available:
● Position feedback module
● Alarm module
● SIA module
● Mechanical limit switch module
● EMC filter module
● Internal NCS module
