Correct use

The FT 50 C...S1 is a colour sensor for the detection of objects in varying colours in proximity mode (for
opaque objects) and reflector mode (for transparent objects).
WARNING
The product is not approved for the protection of personnel (no safety component according to
Machinery Directive).

Performance

The colour sensors of the FT 50 C...S1 series are ideal for on-line colour detection in industrial procedures and
processes.
• Reference colours are easily stored using a teach-in process – either by pressing a button on the sensor or via
an external input cable.
• Colour selectivity (colour and intensity) can be individually adapted to the particular application during the
teach-in process.
• With inhomogeneous colour surfaces, a colour range / colour spectrum can be scanned.
• It is possible to add reference colours or extend the colour range by up to 4 steps using the „Teach +" / „Scan
+" function without spanning too large a colour range. A high colour selectivity is thus also achieved via a larger
colour range with up to 5 colour characteristics.
• In operating conditions, the colour of the object is compared with the reference values which have been taught
and the result is indicated via the integrated switching output.
All FT 50 C ...S1 sensors are equipped with a bus-compatible, serial interface (RS485) for bi-directional transmission
of colour values as well as the setting of sensor functions. The overriding control system controls data exchange.
Data transfer occurs through an exchange of short telegrams.
• This makes it possible to teach-in any number of colours and store them as colour vectors (reference value incl.
tolerances) in the control system via the interface.
• Before beginning the process, the relevant reference colour is transferred back to the sensor. In operating con-
ditions, the sensor compares the actual colour with the reference colour and signals the result to the switching
output. Repeated teaching of colours is unnecessary.
• During on-line access via the RS485 interface, there are 2 further possibilities:
- The internally stored colours / colour ranges (max. 5) can be evaluated separately.
- The actual values can be transferred via the interface. In this case comparison between
the actual colour and the reference colour is carried out via the control system.
Other sensor performances at a glance:
• Colour detection possible even in transmitted light (on reflector)
• High colour selectivity, insensitive to variations in scanning distance
• Adjustable signal mode (N.O. / N.C)
• Choice of operating mode - either permanent or triggered (blanked out)
• Connector plug can be rotated by 270°
• Maintenance-free
