11.4.2 Checklist for safeguarding danger areas
For SOLID-2 Safety Light Curtain, parallel approach to the protective field
This checklist represents a help tool. It supports but does not serve for the inspection
before initial operation or the 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 during the calculation of the minimum height and is this result
considered?
yes no
• Has the safety distance been calculated according to the valid
formula for
safeguarding danger areas
and has this minimum
distance between the most distant beam and the danger point
been 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 danger point 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 danger
point 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 condi-
tion?
yes no
• Are all connectors and connection cables in fault-free conditions? yes no
• Is the start/restart button for starting/restarting the AOPD positi-
oned outside the danger zone and is it effective?
yes no
• Are the safety outputs (OSSDs), linked into the downstream
machine control in accordance with the required safety category?
yes no
• Are the downstream circuit elements controlled by the AOPD, e.g.
contactors with positive-guided contacts or safety valves, monito-
red by the feedback circuit (EDM)?
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
• Is a possibly connected Section Emergency STOP button effective
and after its resetting, is pressing and releasing of the start/restart
button required to start the machine again?
yes no
