Functional Description DLS2
The DLS2 sensor is a digital line and edge sensor for web guiding applications. The
sensor recognizes different lines and can be setup to follow either the middle of a line,
the edge of a line or the edge of web. DLS2 can handle intermittent lines and also lines
that are being touched or crossed by a pattern.
The sensor works with a LED CCD-array with different colours for best illumination
and maximum contrast on the material. It is able to choose the best illumination by
means of powerful Digital Signal Processing algorithm.
The parameters for optimal contrast, control mode, line parameters, etc. will be stored
fail-safely after a calibrations process and are the reference for the following web
guiding process.
A LED-Display shows the position of the line as a moving point according to its
position within the detection range of the sensor. An edge is being displayed as a
moving bar from either side (depending on contrast polarity).
The sensor can easily and accurately be positioned with a light spot and the focussing
function. The line position can be optimised and made visible on the LED display.
Note
The DLS2 sensor cannot be combined with the web guiding controller for motorized
traverses BKS309.W.M
