beam channels receive lights / are blocked.
Ɣ Manual setting : Each beam channel can be set to “effective / ineffective” in the fixed blanking
function respectively.
When the fixed blanking function is used, the safety output 1 / 2 of SF-C14EX are not
turned OFF even if the particular beam channels of SF4B / SF4B<V2> series are blocked.
By using a protection structure etc., make the dangerous parts of the machine inacces-
sible to personnel through the sensing area of the particular beam channels of SF4B /
SF4B<V2> series.
