11 FINAL CONTROLS
Control that the area protected by the barrier is free of obstacles; check
that the safety outputs open correctly by interrupting the protection rays
(BREAK
led lit, machinery under control stops).
12 ROUTINE CONTROLS AND MAINTENANCE
There follows the list of recommended controls that should be carried out
on a regular basis by qualified personnel:
x Check that the barrier remains blocked by inserting an object that
intercepts the rays along the entire length of the protected area.
x Check via the opening of the TEST/RESTART contact, that the
safety relays open (red led lit and controller machinery stopped).
x 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 barrier is
no less than that calculated as per formulas 4.1 and 4.2.)
x Check that it is not possible for a person to get between the barrier
and the dangerous parts of the machinery.
x Check that there is no external damage to the barrier 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 barrier is used.
