Configuration of blanking
Blanked areas require a separate risk analysis!
A blanked area is in principle a hole in the protective field. Check in detail whether and
where blanking is actually required. You must protect the blanked area in another way, e.g.
mechanically. Otherwise you must take the blanked area into consideration in the calcula-
tion of the safety distance and mount the safety light curtain appropriately.
After modifying the blanking, check the protective field with the test rod. Instructions
can be found in chapter 8.3.3 on page 86.
Also pay attention to the warnings in the related chapter.
You can configure blanking of fixed areas in the CDS on the C4000 (receiver).
For blanking fixed areas, you configure:
the maximum number of objects (1 to 5)
a key-operated pushbutton for teach-in (see section 7.11 “Key-operated pushbutton for
teach-in” on page 82).
The C4000 switches to red, if …
more objects or fewer objects than taught-in enter the protective field.
the taught-in object size changes by more than the tolerance allowed.
the object leaves the taught-in position by more than the tolerance allowed.
Limits for teach-in operation
Objects are only reliably taught-in if the objects to be taught-in have a size of at least
20 mm. With objects <20 mm, no blanking may be taught-in in certain circumstances.
This situation can result in shutdowns in the event of vibration of the object. In this
case, slight re-adjustment and/or teaching-in the areas again may rectify the problem.
At least one beam must remain without interruption between the objects.
The first or the last beam of the protective field must remain free.
At variance with the operating instructions for the SICK UE402 switching amplifier, you do
not need a reset button for the teach-in function and will need a key-operated pushbutton
for teach-in instead of a key-operated switch for teach-in.
