Manual setting : Each beam channel can be set to “effective / ineffective” in the fixed blanking
function respectively.
3-1 Functional Descriptions <When Using with Light Curtain
SF4B / SF4B<V2> Series Only>
This section describes each function when using with
SF4B

series only.
When using with
SF-C14EX
, refer to “
3-2 Functional Descriptions <When Using in Combina-
tion with Application Expansion Unit SF-C14EX>
.”
When the fixed blanking function is used, the control output (OSSD 1 / 2) of
SF4B
/
SF4B<V2>
series is not turned OFF even if the particular beam channels are blocked.
By using a protection structure etc., make the dangerous parts of the machine inaccessible
to personnel through the sensing area of the particular beam channels.
