Page 3: Safety Instructions
BKS020.xxx.480.75.D.582339 With (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. -
Page 4: Functional Description Dls2
DLS2 can handle intermittent lines and also lines that are being touched or crossed by a pattern. -

• Sensor DLS2 • Mounting bracket (BKS.W.V.A.20x20.DLS2) • Operation Manual Not in the scope of delivery are: • Connection cable (length according to customer specification). • Sensor adjustment / mounting (BKS.W.DLS2.020.2.XXX.YYY) Length of guiding rod depends from the webMASTER type. -
Page 6: Installation
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. -
Page 7: Wiring
Operating Manual DLS2 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... -
Page 8: Operational Parameters
(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. -
Page 9: Operation Panel
Operating Manual DLS2 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. -

Page 11: Commissioning Of The Dls2
7 Commissioning of the DLS2 7.1 Initialisation Phase Note If you retrofit a DLS2 sensor to an existing controller you have to restart the controller after the installation of the sensor. This will allow the controller to detect the DLS2 sensor correctly. -
Page 12: Horizontal Positioning
Operating Manual DLS2 7.3 Horizontal Positioning In Normal Operation Mode an adjustment add can be called up by pressing three times key. The two small green LEDs above the key will light indicating that the adjustment mode was activated. The sensor will project two small red light dots which are vertically staggered. -
Page 13: Contrast Measuring
Operating Manual DLS2 7.5 Contrast Measuring The contrast describes the transition of the printed line and its background (dark - bright intersection). The higher the contrast the better will be the detection of the line. The contrast can be measured by pressing once the key. -
Page 14: Sensor Calibration
The Calibration Procedure can be considered as a learning and optimisation process of the sensor. The DLS2 gathers the characteristics of the line. Properties like line width, contrast on left line edges, contrast on the right line edge and line colour are measured and stored. -
Page 15: Different Operation Modes
● Holographic pattern • Material edges ● Printed pattern In order to optimise the detection of above objects the DLS2 sensor must be set in the right operation mode. There are 5 operation modes: • Line Detection ● Hologram Detection •... -
Page 16: Material Edge Or Line Detection Mode
LED above the key will light to confirm that the mode was activated. The switch to Hologram Detection requires a re-calibration of the DLS2, if no profile for such a material-object combination exists. The calibration in the Hologram Detection Mode is carried out analogous to the procedure described in section 7.6 “Sensor... -
Page 17: Normal Operation
8.3. If the line or edge is missing none LED will shine. Longer unintended line interruptions are recognised by the DLS2 and it sends a special signal to the web guide controller. In such a case the controller blocks the steering frame at the actual position until the line is recognised again. -
Page 18: Profile Management
Fig. 7: Profile Management Panel DLS2010 Each of the 9 elements on the LED-Display represents a profile. Hence the DLS2 can store 9 different profiles. The status of the profiles are visualised by the manner the LED-Element is shining. Following table shows the different profile states. -

LED. 3. Press the key for longer than 3 sec. to adopt the selected profile. This action terminates the Profile Management mode and brings the DLS2 to normal operation. 9.3 Save Profile 1. Calibrate DLS2 with material-reference-combination. 2. Check calibration with a test run. -
