•
The device must be affixed so that no small objects (e.g. cables) are in the
protective field, even if the safety outputs do not switch to the OFF state as a
result.
•
The device must be affixed so that no obstacles disrupt the safety sensor’s field
of view. Take additional protective measures if a risk arises due to unavoidable
obstacles.
•
If people can stay between the protective device and the hazardous point without
being detected, check if additional protective measures (e.g. restart interlock) are
required.
•
Reaching under, over and around, crawling beneath and stepping over the device,
as well as moving it, must be prevented.
WARNING
Risk of ineffectiveness of the protective device!
Persons and parts of the body to be protected may not recognized in case of non-obser‐
vance.
The optical beam path must not be disrupted, e.g. if the system is incorporated into
paneling.
•
Do not attach an additional front screen.
8.5
Response time of the device
The device’s response time must be taken into account, among other things, so that
the device can be positioned in a suitable location and the protective fields can be
sized correctly.
The response times are specified in the technical data.
8.6 Contour as Reference field
The contour as reference field monitors a contour of the environment. The device
switches all safety outputs to the OFF state if a contour does not match the set
parameters, because, for example, the mounting of the device has been changed.
The contour as reference field detects unintentional and intentional changes to the
position or alignment of the device. Unintentional changes may be caused, for example,
by vibrations. An example of an intentional change is deliberate tampering to disable
the device’s functionality.
National and international standards require or recommend that a contour as reference
is monitored, if the safety sensor is used in vertical operation for hazardous point
protection or for access protection.
WARNING
Risk of ineffectiveness of the protective device!
Persons and parts of the body to be protected may not be recognized in case of
non-observance.
•
Use a contour from the environment as a reference to protect the protective device
from inadvertent adjustment or tampering.
