Checklists

The test before initial commissioning ensures the safety-related fault-free integration of the active opto-
electronic protective device (AOPD) into the machine and its control. The results of the test must be written
down and kept with the machine documents. They can then be used as a reference during subsequent
regular testing.

10.4.1 Checklist for access guarding

NOTE
This checklist is intended as a help tool. It supports but does not replace the test before initial
commissioning or regular testing by qualified persons.
Only with general applications, i.e. in cases in which SOLID-2SF is not used for
guarding the sheet delivery of a sheet-fed printing machine:
Was the safety distance calculated according to the applicable formula and specifica-
tions and is this minimum distance observed between the protective field and the point
of operation?
Are the required beam heights of the lowest and the highest beam complied with?
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 safety
components?
Is the external condition of the protective device and command devices fault-free?
Are transmitter and receiver fixed against displacement/turning after alignment?
Are all connectors and connection cables in fault-free condition?
Is the start/restart button for resetting the AOPD mounted outside of the danger zone
in accordance with specifications in such a way that it cannot be reached from within
the danger zone? Can the entire danger zone be seen from the place at which the
start/restart button is installed?
Are the safety-related switching outputs (OSSDs) integrated in the downstream
machine control acc. to the required safety category?
Does the actual integration of the AOPD into the machine control comply with the
circuit diagrams?
Does the AOPD respond correctly when any beam* is interrupted and does the
system lock (inevitable with activated start/restart interlock as only the access not the
presence of a person in the danger zone is detected)?
When the AOPD is separated from its supply voltage, does the dangerous movement
stop, and, after the supply voltage has been restored, is it necessary to actuate the
start/restart button to reset the machine?
