8. REGULAR CHECKS AND MAINTENANCE

Qualified personnel must carry out the following checks regularly.
Ensure that:
•
The SAFEasy device switches to an OFF state when the check with
the test rod is carried out, and remains in the BREAK condition as
the rod is passed across the whole protected field.
•
The SAFEasy device switches to an OFF state when the TEST
button is operated (red LED BREAK is lit – signal at the OSSD
outputs switches from High to Low - monitored machine switches to
a safe condition).
•
The reaction time at a machine stop, incl. ESPE reaction time and
machine overrun time, is within the limits defined through the
calculation of the safety distance (see Ch. 2 "Installation").
•
The minimum safety distance between the danger zone and the
protected field on the PSEN op2H is in accordance with the details
stated in Ch. 2 "Installation".
•
Nobody can access and remain in the danger zone between the
SAFEasy device and the hazardous machine parts.
•
The danger zone cannot be accessed from any unprotected area.
•

external electrical connections.
•
The interval between such checks depends on the respective
application and on the conditions under which the light curtain is
operated.
