3-2 Functional Descriptions <When Using in Combination with
Application Expansion Unit SF-C14EX>
This section describes each function.
3-2-1 Fixed Blanking Function
This is a function that the safety output 1 / 2 of
SF-C14EX

beam channel(s) is blocked OFF.
~;;%|}}${Y
There are “Clear,” “Auto” and “Manual” for the setting method.
G& ~*&"{%&Y
Auto setting
: The currently blocked OFF beam channels are set as “effective beam channels”
*&;
emitter emits light. Furthermore, this function cannot be set in the state where all
beam channels receive lights / are blocked.
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

series.
