9 FINAL
CHECKS
•
Check that the area protected by the SLC is free of obstacles.
•
Check that the safety outputs open correctly by interrupting the
protection beams (BREAK LED lit, machinery under control stops).
10 ROUTINE CONTROLS AND MAINTENANCE
These checks are recommended and should be carried out on a
regular basis by qualified personnel:
•
Check that the SLC remains blocked by inserting an object that
intercepts the beams along the entire length of the protected area.
•
Check via the opening of the
TEST/RESTART
contact, that the
safety relays open (red LED lit and controller machinery stopped).
•
Check that it is not possible to access the danger areas of the
machinery from any area that is not protected and that the
minimum distance between the dangerous areas and the SLC is
no less than that calculated as per formulas 4.1 and 4.2.)
•
Check that it is not possible for a person to get between the SLC
and the dangerous parts of the machinery.
•
Check that there is no external damage to the SLC and/or to the
external electrical connections.
The interval between the above actions depends on the individual
application and the conditions in the environment where the SLC is used.
