12.4.2 Checklist for danger zone guarding
For a SOLID-4 Safety Light Curtain with parallel 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.
• The minimum height of the protective field above the reference plane relates
to the resolution of the AOPD. Was the resolution used when calculating the
minimum height and is this height ensured?
Yes No
• Is the safety distance calculated in accordance with the applicable formulas
for danger zone guarding and is this minimum distance between the most
distant effective beam and the point of operation observed?
Yes No
• During risk assessment, has it been ensured that only protective field
heights less than 300 mm above the floor are regarded as low enough not to
be crawled under (EN 999)?
Yes No
• Is the access to the point of operation only possible through the protective
field of the AOPD and are other access possibilities, especially from the
sides, protected by suitable hard guards or other means?
Yes No
• Is unprotected presence between the next beam and the point of operation
definitively excluded?
Yes No
• Are transmitter and receiver fixed against displacement/turning after the
alignment?
Yes No
• Are the protective device and the control devices in good, fault-free
condition?
Yes No
• Are all connectors and connecting cables in fault-free conditions? Yes No
• Is the start/restart button for starting/restarting the AOPD positioned outside
the danger zone and is it effective?
Yes No
• Are the safety outputs (OSSDs) linked into the downstream machine control
unit in accordance with the required safety category?
Yes No
• Are the downstream circuit elements controlled by the AOPD monitored by
the feedback circuit (EDM), e.g. contactors with positive-guided contacts or
safety valves?
Yes No
• Does the actual integration of the AOPD into the machine control unit match
the circuit diagrams?
Yes No
• Is the AOPD effective during the entire dangerous movement of the
machine?
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
machine again after the supply voltage returns?
Yes No
