14 Maintenance, repair and disposal
• Maintain the optoelectronic protective equipment in accordance with the
applicable national regulations in effect within the requested intervals. The tests
must be performed by qualified persons.
• It is recommended to regularly clean the front panes of the transmitter and the
receiver.
• Clean the unit with a clean, damp cloth. In particularly dusty environments we
recommend to spray the cleaned front pane with an antistatic product.
• Do not use any aggressive or abrasion-developing cleaning agents since they
could attack the surfaces. To avoid electrostatic charging on the front do not
use any woollen cloths.
Scratches on the front panes of the photoelectric safety sensors can deviate
the light beams and impair the protective function.
• Only the manufacturer is allowed to repair the unit.
• After use dispose of the unit in an environmentally friendly way in accordance
with the applicable national regulations.
