Safety
For mounting, operating and testing, this document, the original operating instruc-
tions as well as all applicable national and international standards, regulations,
rules and directives must be observed. Relevant and supplied documents must be
observed, printed and handed to the affected personnel.
Before working with the product, completely read and understand the documents
applicable to your task.
The protective function is only ensured if the safety sensor is mounted appropri-
ately and properly for the intended area of application.
Ä
Only allow competent personnel to install the safety sensor.
Ä
Maintain the necessary safety distances. Also observe the minimum distance
to reflective surfaces.
Ä
Prevent optical crosstalk between adjacent systems.
Ä
Make sure that stepping behind, crawling under or stepping over the protec-
tive device is reliably ruled out and reaching under, over or around is taken
into account in the safety distance, if applicable with additional distance CRO
corresponding to EN ISO 13855.
Ä
Take measures to prevent that the safety sensor can be used to gain access
to the danger zone, e.g. by stepping or climbing into it.
Ä
Clean the devices regularly.
Ä
For access guarding, activate the start/restart interlock as only entry into the
danger zone is detected and not whether a person is located within the dan-
ger zone.
Ä
The acknowledgment unit for unlocking the start/restart interlock must not be
reachable from the danger zone, and the entire danger zone must be clearly
visible from the location at which the acknowledgment unit is installed.
Ä
After mounting, check the safety sensor for proper function.
Ä
Automatic operation of the machine without suitable protective device is not
permitted. Before performing maintenance work, e.g. conversion, setup or
testing, shut down the system safely and/or take other measures to mitigate
risks.
