Horizontal Positioning
In Normal Operation Mode an adjustment add can be called up by pressing
three times
the
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. The sensor can be positioned by moving it along the rail until
the dots cover the object (line or edge) it has to recognise on the material. Once aligned,
the sensor can be locked by a corrugated-head screw.
The horizontal adjustment mode can be terminated by either pressing the
key once
or waiting 30 sec.

Adjustment of Focus
The quality of the line or edge detection depends form several parameters. The focus is
an important parameter for proper functioning of the sensor. The focus is given by the
correct distance between sensor and material web. The best way of adjusting the focus
distance is by using a suitable material with a printed straight line with good contrast.
There is a procedure to set the correct focus distance. The procedure is started by
pressing
twice
the
key. The small green LED on the right side of the key will
light. The focus quality can be influenced by moving the sensor closer or farther away
from the material. The improvement of the focus is indicated by the LED pattern as
follows:

The focus adjustment procedure can be terminated by either pressing the
