PREVENTIVE PERIODIC INSPECTIONS
The EU directive on the use of machinery equipment stipulates the
regular inspection of safety devices. Light curtains and access control
barriers must be periodically tested by qualified and trained person-
nel. This allows early detection of new hazards and helps maintain the
necessary level of safety. At the same time, it should be checked that
the protective devices operate in accordance with the current use of
the machine. Periodic inspections give the opportunity to ensure that
the type of protective device corresponds to the hazards actually en-
countered, that the user cannot bypass it and that nothing hinders its
functionality.
Please use a form such as the one on table 8 of this manual. It will help
keep track of periodic testing.
CLEANING
In order to keep the protective device in full operating condition and
prevent potentially biased results, the active screens on the sender and
receiver units must be regularly cleaned. The cleaning frequency de-
pends on the ambient air pollution and the presence of dust and dirt on
the screen. Use a mild and non-abrasive detergent to remove dirt from
these surfaces, then dry the screen with a soft cloth. After cleaning, the
daily functional test, as described above, must be performed in order to
detect potential position changes of the protective devices.
DAILY TESTING LOG FILE
The following tests must be carried out every day the protective device
is in operation.
The tests must be conducted by authorized and trained personnel, and
entered in a log file as printed on table 8 of this manual.
–
Check for signs of external damage, particularly to the front screen,
the mounting or the electrical connections.
–
Check that it is not possible to access the machine’s danger zone
from any unprotected area.
–
Test the protective field: Perform the daily functional test as de-
scribed above.
If any of the above tests have failed, block the machine immediately to
prevent its use and notify the supervisor.
