 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 / SF4B<V2> 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.

3-1-2 Floating Blanking Function
This function is set in each SF4B / SF4B<V2> series.
If the number of the blocked beam channels is less than the set number of the beam channels, the
control output (OSSD 1 / 2) of SF4B / SF4B<V2> series is not turned “OFF.”
This function is useful when an obstacle moves within the sensing area.

Setting of the muting function on each beam channel
 Each beam channel can be set to “effective / ineffective” in the muting function respectively. (Note)
 The factory setting of this function is effective for all beam channels.
Note: If the beam channel set to ineffective in the muting function is blocked, the control output (OSSD 1 / 2) becomes “OFF” and
the muting function is canceled.
 There are two setting methods, “Auto” and “Manual” to set muting beam channel.
 Auto setting : The beam channel which is currently blocked is set as the “effective” beam
channel. When all beam channels are in light receiving condition, the setting is
not accepted. Furthermore, in the state where emission is halted or all beam
channels are blocked, the all beam channels become “effective” in the muting
function.
 Manual setting : Each beam channel can be set to “effective / ineffective” in the muting function.
ON: The muting function is effective
OFF: The muting function is ineffective

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-

3-2-2 Floating Blanking Function
This function is set in each SF4B / SF4B<V2> series.
If the number of the blocked beam channels is less than the set number of the beam channels, the
safety output 1 / 2 of SF-C14EX are not turned “OFF.”
This function is useful when an obstacle moves within the sensing area of SF4B / SF4B<V2> series.
The factory setting of this function is “ineffective.”

3-2-3 Auxiliary Output Switching Function
This function changes the operation state of the auxiliary output (AUX4) of SF-C14EX. It is useful
when desired to make an indicator to operate or inform the operation state of the SF4B / SF4B<V2>
series to PLC.
The following settings are selectable.
