Configurable functions
For floating blanking with partial object monitoring and for fixed blanking with increased
s
ize tolerance, a hole is produced in the protective field for technical reasons. With the
aid of Tab. 12 you can determine the effective resolution of the safety light curtain at this
point and the minimum size of an object to ensure that the safety light curtain reliably
switches to red.

Warning: During operation with “Reduced resolution” or “Blanking” the minimum
distance that corresponds to the modified resolution is to be observed.
