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

5Installation
5.1 Mounting the Sensor
The sensor requires a square 20x20mm fixation bar that is mounted on the steering
frame according to picture (Fig. 2). The sensor itself is fixed by four M4 screws on the
fixation bracket which is attached to the square bar.
Fig. 2: Mounting of sensor on the square bar, view of tilting device DLS200005
The distance between DLS2 and material web should be 16 mm [0.62”].
The 4 screws on the side of the sensor allow tilting the sensor around the focus point.
This can be required with reflective materials.
5.2 Right or left hand position of the sensor
Definition of Left and Right
Left and right are always seen in direction of
the running web (Fig. 3).
The DLS2 line sensor can be used on both
sides of the steering frame. The line sensor
can replace an ultrasonic sensor US01/ 04B
or an optical sensor AZS01/04A. No
reconfiguration of the web guide controller
is necessary after the replacement.

Note
Regardless of the mounting side, the DLS2 line sensor must always be connected to the socket
for the RIGHT material sensor.
5.3 Wiring
Electrical connections:
If the sensor is used with a web guide
controller built-in in a FMS steering frame
of the webMASTER series, the sensor is
connected with a cable 4x0.14mm2 of
the respective length. We recommend
using FMS original cables. The cables can be
ordered at FMS.
Fig. 4 shows the sensor connector in
front view with its pin assignment. The
table lists the wire colour corresponding to
the signal names.
5.4 Using the DLS2 with FMS Web Guide Controllers
If using the DLS2 sensor with older web guide controllers of the types BKS110C and
BKS309, it may be necessary to adapt the driver strength of the 24 VDC supply of the
controller to the new sensor requirements. This is achieved by adding a wire bridge in
the 24V supply. The table below indicates in which cases this modification is necessary
and where the bridge has to be applied.

Caution
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.

6.1 Operational Parameters
(SW) Sensing Width: 8mm
(FD) Focal Distance: 16mm typical
(14mm min., 18mm max.)
(LW) Line Width: min. 0.5mm, max. 5.0mm
(LL) Line Location: Minimum 8mm from the
material edge (or from
adjacent printing that may
cause interference)
Line Break: DLS2 recognizes unintentionally
interrupted lines. With a break in the line the sensor
provides a square wave output signal. This alarm
signal can be used to shutdown the production line
and prevent material loses (ref. to 8.6 Normal
Operation).
Line Contrast: High contrast between the line
colour and the background colour (for example a
black line on a white background) will provide for optimum operation of the sensor.
The DLS2 sees colours differently as the human eye. Colour combinations (red and
brownish colours) are under certain circumstances not easily recognized. In particular, if
there is little contrast between the background printing and the printed line, a
disturbance can occur. For optimum performance where low contrast is a factor, the
line location (distance between background printing and the line) can be increased e.g.
from 8 to 10mm. This will benefit the operation of the sensor.
Clear Material: Tracking a line of sufficient contrast on clear material is typically
straightforward provided that a background is utilized with good contrast to the line
colour (e.g. black line – white background, white line – black background). A distance
of approximately 3mm between clear film and background (behind the film) is
recommended.
Reflective Material: It may be beneficial to adjust the sensor at an angle to the
material in order to reduce reflections.
Note
FMS will evaluate your product in order to confirm suitability with the Digital Line
Sensor. Please contact your local FMS Representative or FMS directly for further
information.

6.2 Operation Panel
The operation panel (Fig. 6) consist of a foil type key pad and a LED-Display. The later
is used to display the actual line or edge position or status information of the sensor e.g.
in form of a LED pattern. A small green LED is assigned to all keys that own an
operation. These LEDs confirm the function that was activated
