Applications in which the measures described above are inadequate
are also conceivable. This applies for instance with continuous and
heavy vibration, increased or too low ambient temperatures and in the
case of nuclear radiation.
The separate attachment of position displacement sensor and
controller unit can help here. A universal component is available which
is suitable both for linear and part-turn actuators.
You require the following:
The external position detection system (order no.

C73451-A430-D78). This consists of a SIPART-PS2-housing with
integrated friction clutch, built-in potentiometer and various dummy
plugs and seals.
or a Non-Contacting Position Sensor (e.g. 6DR4004-6N).
S
The controller unit, any positioner version.

The EMC filter module, this is is a set together with cable clips
S
and M-20 screw-type cable gland and has the order number
C73451-A430-D23. The EMC filter module must be installed in the
positioner. The installation instructions enclosed with the EMC filter
module explain how to assemble the components.
A 3-wire cable for connecting the components.
S
This EMC filter module should always be used for the controller unit
when any actuator-mounted potentiometer (resistance 10 kΩ) is to
be used instead of the position detection system C73451-A430-D78.
WARNING
The explosion-proof version may not be run together with the external
position detection system.
