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.
When powered up the DLS2 will initialise all parameters and will load the last profile
used. If no profiles or calibration data are available (e.g. when used the first time), the
sensor can’t go to Detection Mode and it needs to be calibrated. In this case the LED
display will indicate un-calibrated status with a light pattern with even and odd LEDs
flashing in alternation.
All even LEDs shining
All odd LEDs shining
In order to enter the Detection Mode the DLS2 needs to be calibrated. The following
section 7.2
describes how to initialise and calibrate the DLS2 sensor. If an existing
profile with calibration data was loaded the sensor will change to the Detection Mode.
The LED line will in this case display the position of the line or edge depending of the
used mode.

Quick Installation Guide / Initialisation Procedure
The following procedure deals with commissioning the DLS2 sensor in line detection
mode. The initialisation in other modes (e.g. edge detection) is carried out analogous.
Instructions and information for the other modes can be found in
section 8
„Different
Operation Modes“.
Initialisation Procedure:
1.
Mount the sensor on the steering frame (see
section 5.1
and
5.2
)
2.
Wiring the sensor (see
section
5.3)
3.
Choice of material: Choose a white paper web with a printed black line of 2 mm
[0.08“]
4.
Perform Horizontal Positioning of DLS2 (see
section
7.3
)
5.
Perform Focus Adjustment Procedure (see
section 7.4
)
6.
Do Contrast Measuring (see
section 7.5
)
7.
Perform Calibration Procedure (see
section 7.6
)
8.
If necessary store profile of calibration (see
section
9.3)
