1Safety Instructions
1.1 Description Conditions
a) Danger of health injury or loss of life
Danger
This symbol refers to high risk for persons to get health injury or loss life. It has to be
followed strictly.
b) Risk of damage of machines
Caution
This symbol refers to information, that, if ignored, could cause heavy mechanical
damage. This warning has to be followed absolutely.
c) Note for proper function
Note
This symbol refers to an important information about proper use. If not followed,
malfunction can be the result.
1.2 List of Safety Instructions
If a Digital Line Sensor DLS2 is used in combination with older web guide
controllers of the types BKS110C and BKS309 V1.63 or older, a wire bridge
needs to be added in the 24 V controller supply. Consult the wiring diagram and
wire terminal arrangement in the operation manual of the respective controller to
apply the bridge.
With special web guide controllers e.g. of the type BKS020.xxx.480.75.D.582339
(ABG) the DLS2 sensor must be mounted on the right side of the steering frame.
In web guiding systems all equipped with FMS components and a DLS2 sensor it
may happen that the web guide controller blocks the steering frame. This
protective function is activated when the line is interrupted and impossible to be
detected. It avoids the steering frame from skittering away and material loses.
In addition the DLS2 generates at permanent line interruption an alarm signal
that can be used to shutdown the production line

2Functional 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
