2.4

Conformity with European directives

The CE marking on the device shows conformity with the regulations of the following European guidelines:
Electromagnetic Compatibility
EMC
2004/108/EC
Atmosphère explosible ATEX
94/9/EC
The applied standards can be found in the EC conformity declaration of the device.
2.5 Loss of safety of device with type of protection "Intrinsic safety Ex i"
WARNING
Loss of safety of device with type of protection "Intrinsic safety Ex i"
If the device has already been operated in non-intrinsically safe circuits or the electrical specifications have not been
observed, the safety of the device is no longer ensured for use in hazardous areas. There is a danger of explosion.
● Connect the device with type of protection "Intrinsic safety" solely to an intrinsically safe circuit.
● Observe the specifications for the electrical data in the certificate and in Technical data (Page 31).
WARNING
Unsuitable device for the hazardous area
Danger of explosion.
● Only use equipment that is approved for use in the intended hazardous area and labelled accordingly.
3 Description
3.1 Function
The positioner facilitates the separate installation of the position acquisition system. The stroke or rotary angle is registered
directly at the drive by means of a non-contacting position sensor. It is therefore possible to install the controller unit at some
distance away, e.g. on an assembly pipe or similar. The positioner is wired to the position sensing system by means of
electrical cable. The positioner is connected to the drive via one or two pneumatic lines.
Such a separate installation is useful whenever the ambient conditions at the fitting exceed the specified positioner values.
The NCS consists of a molded sensor for fixed installation and a magnet. The magnet is mounted to the spindle on linear
actuators, or to the stub shaft on rotary actuators. The sensor housing is mounted onto the console on rotary actuators and
to the bracket on linear actuators. The bracket can be a NAMUR type, or any other mounting bracket.
Auxiliary power is supplied to the NCS via the EMC filter module C73451-A430-D23 and EMC-compatibility is ensured at the
same time.
EMC filter module ordering options:
● Installed in the positioner; see Catalog FI 01
● For retrofitting in the positioner; order number C73451-A430-D23. For information on retrofitting the EMC filter module,
refer to the positioner operating instructions, chapter "Installation/Mounting".
