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 position detection system (order no. C73451--A430--D78). This
S
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.
S
The EMC filter module, this is a set together with cable clips and
S
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 always has to be used for the controller unit
whenever the external position detection unit C73451-A430-D78 is to
be replaced by a random drive--mounted potentiometer (resistance va-
lue 10 kOhm) or if a NCS sensor is to be installed.
WARNING
The explosion proof version may not be run together with the external
position detection system.
