9 FINAL CHECKS.
Check that the area protected by the barrier is free from any obstacle; check
the correct triggering of the safety relay opening by interrupting the protection
rays (red LED switched on, controlled machine stopped). CAUTION! If the
red LED switches on and off, check the correct mechanical assembly.
NOTE.
This check must be repeated each time you move or
mechanically re-align the photocells.
10 ROUTINE MAINTENANCE OPERATIONS.
Here is a list of checks recommended to the user to be carried out
periodically by skilled workers:
•
Check that the barrier locks by inserting an object detecting the single
elements of each photocell.
•
By opening the test contact, check that the safety relays are opened
(red LED switched on and machine under test stopped).
•
Make sure that the access to the machine dangerous areas is not
possible from any non-protected area and that the minimum distance
from the barrier dangerous parts is not lower than the one calculated
with reference to the formula reported at paragraph 4.1
.
•
Check that it is not possible for a person to stop between the barrier
and the dangerous parts of the machine.
•
Make sure that there is no outer damage to the barrier and/or the outer
electrical connections.
•
Make sure that the response time - including the barrier and the
machine ones - does not exceed the established limits.
The frequency of these operations depends on the special applications and
operative conditions according to which the barrier is working.
