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�
