POSITIONING AND ADJUSTMENT OF SENSOR ELEMENTS FOR SLG 415 L AND SLG 415 T
As already mentioned, the pre-assembled systems SLG 415 L and SLG 415 T kits consist of a
vertical light grid and of one (SLG 415 L series) or two (SLG 415 T series) horizontal sensor
element in which the Muting sensors are integrated.
The system is equipped with a VERTICAL adjustment of the sensor elements to solve the
following problems:
•
Incorrect and non-continuous sensor beam interception by the material in movement.
• Need to reduce the beam intensity when transparent objects (i.e. glass, plastic, etc)
are detected.
At the operating range limits (1 ÷ 2,5m) or in dusty environments, it would be necessary to use
the ANGULAR adjustment to reach the maximum signal intensity. (SCHMERSAL advises against
this operation with transparent materials).
The following figure shows the two axes (horizontal and vertical) on which to operate.
To make the adjustment:
•
loosen the Allen screws;
•
operate on the arms to make the adjustments;
•
tighten the Allen screws.

For installations that do not require any particular adjustments, the SLG 415 L and SLG 415 T
systems are pre-aligned and do not require further regulation.
