General information related to determining detection zone contours
•
Shadow effects (e.g. surfaces or areas located behind stationary objects) must be
considered. As a rule, insufficient safeguarding must be adequately supplemented
by further safety measures such as guard fences, light curtains, and the like!
•
Access to the detection zone in the dangerous area is not permitted.
•
When setting the dimensions of the detection zone, you must comply with the
formulas cited in Chapters 5.4.8 and 5.7.9 ! Be sure to comply with higher-level
machine standards (e.g. DIN EN 1525) if applicable.
These contain individual specifications, for example, on points of access to the
danger zone and, if applicable, detection zone additions that must be given special
consideration.
They also provide information on how to measure safety distances at machines.
•
Detection zones with a radius smaller than 20 cm (at or close to the scanner) are
not admissible. 20 cm is the preset minimum contour.
•
When setting the dimensions of the detection zones, please comply with the
maximum angle error stated in the technical specifications (Chapter 14.11).
•
Needle-shaped detection zone contours are not permitted, since they do not
ensure any protective effect. For additional information, please refer to the
SIMATIC FS600 Parameterization Software LS4soft user software (Chapter
entitled “Definition of Detection Zones”).
•
Due to possible measurement errors, every detection zone has an additions area
in which detection is not guaranteed under all conditions. Please consider as well
Chapter 5.3.5. Read Chapter 5.4.6 and 5.7.7 for information on optimizing system
availability.
•
The required safety distances must be taken into account when making detection
zone configurations. Safety distances are calculated according to formulas found in
either the machine-specific C standards or the general B standards IEC 61496-3 in
combination with DIN EN 999 (see Section 2 and 5 of the standard). Tolerance
fields and/or additions
(make sure to consider Chapter 5.4 and 5.7).
•
After the detection zones have been set, make a printout of the following
information:
-
Detection zone contour with the X and Y coordinates
-
Date
-
Serial number of the scanner
-
Name of the safety official
•
When calculating the additions, be sure to consider whether the dust algorithm is
deactivated or activated (see Chapter 5.3.5).
