11.4.1 Checklist for safeguarding danger points
SOLID-2 Safety Light Curtains (resolution 20 to 40 mm),
normal 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.
• Is the safety distance calculated accordingly to the valid formula
for
safeguarding danger points
, considering the resolution and
the effective response time of the AOPD, the response time of a
possibly used safety interface and the stopping time of the
machine? Is this minimum distance between the protective field
and danger points considered?
yes no
• Is access to the danger point only possible through the protective
field of the AOPD and are other possible accesses protected by
suitable safety components?
yes no
• Is the protective field effective at each position and positively
checked according to Chapter 8.3?
yes no
• Is reaching-over, reaching-under or reaching-around the protec-
tive field effectively prevented, e.g. by mechanical measures
(welded or screwed)?
yes no
• Is unprotected presence between the protective field and danger
point safely excluded?
yes no
• Are transmitter and receiver fixed against displacement 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 resetting the AOPD positioned outside
the danger zone and is it effective?
yes no
• Are the safety outputs (OSSDs), linked into the subsequent ma-
chine control unit in accordance with the required safety category?
yes no
• Are the subsequent 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
• Is the dangerous movement stopped immediately if the supply
voltage of the AOPD is interrupted and is the start/restart button
required to start the machine again after the supply voltage
returns?
yes no
