Mount the unit so that the mounting position cannot change (in
particular avoid high vibrations!). Laser units with a very small
light spot diameter are highly focussed; the slightest change in
the mounting position will result in misalignment.
Adjustment aid
To make alignment easier the intensity of the light spot is increased
during the setting until it becomes clearly visible. In the operating
mode (after step 3 of the setting) the transmitted light is set to normal
intensity.
NB: Commissioning
The retro-reflective sensor is supplied ready to operate (plug and play)
set at the max. sensing range. This is sufficient if the retro-reflective
sensor can operate with maximum excess gain (highest contrast). The
following setting procedures should only be necessary in less straight-
forward applications, for example if partly transparent objects must be
detected.
Setting of the sensitivity with stationary objects
Press for about 2s until the red LED flashes.
Activate the programming mode of the unit.
The red LED goes out; the yellow and green LEDs flash alternately.
The unit is in the programming mode.
