12.4.3 Checklist for access guarding
For a SOLID-4 Safety Light Curtain with normal approach to the protective field
This checklist is intended as a help tool. It supports but does not replace the inspection
before first startup or the respective regular inspections by an expert.
• Has the safety distance been calculated in accordance with the applicable
regulations, and has this minimum distance between protective field and the
point of operation been observed?
Yes No
• Are the required beam heights of the lowest and the highest beam complied
with (see Chapter 6.1.3)?
Yes No
• If access to the point of operation is possible through routes other than the
protective field of the AOPD, are the other access options suitably secured
by other means?
Yes No
• Are the protective device and the control devices in good, fault-free
condition?
Yes No
• Are transmitter and receiver fixed against displacement/turning after the
alignment?
Yes No
• Are all connectors and connecting cables in fault-free conditions? Yes No
• Is the start/restart button for resetting the AOPD positioned outside of the
danger zone in line with specifications so that it cannot be reached from
inside? Is there a complete overview of the danger zone from the start/
restart button position?
Yes No
• Are both safety-related switching outputs (OSSDs) linked into the down-
stream machine control unit in accordance with the required safety cate-
gory?
Yes No
• Are the subsequent switching elements controlled by the AOPD, e.g.
contactors with positive-guided contacts or safety valves monitored via the
feedback circuit (EDM)?
Yes No
• Does the actual integration of the AOPD into the machine control unit match
the circuit diagrams?
Yes No
• Does the AOPD respond correctly when any beam is interrupted and does
the start/restart interlock lock when the beam is interrupted? This is
absolutely necessary, as the access, not the presence in the danger zone is
recorded.
Yes No
• Does the dangerous movement stop immediately if the supply voltage of the
AOPD is interrupted and is the start/restart button required to reset the opto-
electronic protective device again after the supply voltage returns?
Yes No
