INSPECTION AND MAINTENANCE
Verification of safety light curtain / light grid efficiency
Before each work shift or before switching on, check the correct operation of the safety light
curtain / light grid.
For a correct functional testing, the right test object must be used, depending on the resolution of
the light curtain.
•
Introduce the test object into the protected area and move it slowly downward (or
upward), first in the center, then near Emitter and Receiver.
•
For light grids: Intercept one beam or all beams with an opaque object, first in the
center of the detection zone and then close to the Emitter and the Receiver.
•
Make sure that during each stage of the test object’s movements the red LED on the
Receiver is permanently on.

The light curtains / light grids do not require any specific maintenance operations. However,
periodic cleaning of the front surfaces is recommended. Wipe with a clean damp cloth. In
particularly dusty environments, use an anti-static spray after cleaning.
Never use abrasive or corrosive products, solvents or alcohol,
which could damage the
surfaces. Do not use woollen cloths, that would electrify the surfaces.
If the orange LED on the Receiver switches on („weak signal“), check that:
-
the front surfaces are clean;
-
Emitter and Receiver are aligned correctly.
If the LED stays on, please contact
