CHAPTER 10

DEVICE MAINTENANCE

DATALOGIC safety light curtains do not require special maintenance operations.

To avoid the reduction of the operating distance, optic protective front surfaces must be 
cleaned at regular intervals.

Use soft cotton cloths damped in water.

Do not apply too much pressure on the surface in order to avoid making it opaque.

Please do not use on plastic surfaces or on light curtain painted surfaces:

•

alcohol or solvents

•

wool or synthetic cloths

•

paper or other abrasive materials

PRODUCT DISPOSAL

Under current Italian and European laws, DATALOGIC is not obliged to take care of prod-
uct disposal at the end of its life.

DATALOGIC recommends disposing of the product in compliance with local laws or con-
tact authorized waste collection centers.
