Configuration
When floating blanking has been implemented with a C4000 Select device, a hole is pro-
d
uced in the protective field. With the aid of Tab. 14 you can determine the effective
resolution of the safety light curtain at this point and the corresponding minimum object
size that ensures that the C4000 Select safety outputs switch to inactive (low) (i.e. red
state).
