● Override function
WARNING
Design the system such that the test input and the override input can
be manually operated from outside the dangerous area, and also
where the operators can see the entire dangerous area.
This function forcibly turns the safety function into invalid. This func-
tion is used for the following cases: when the customer who uses
the muting function needs to start the product with safety output 2 be
OFF status, when the product is required to continue operating even
though the muting sensor becomes valid after the muting sensor is
turned ON at the starting of line.
The override function becomes valid when all the conditions listed
below are satisfied:
• The incandescent lamp with 3.6 to 30W shall be connected to ei-
ther muting lamp output 1 or 2, or to both of the inputs.
• The signal shall be input to either muting sensor 1 or 2, or to both
of the inputs.
• The override input terminal O1 and O2 shall be short-circuited
and the test input terminal T1 / T2 shall be opened within 1 sec.
(3 sec. continuously). The override function turns ON either short-
circuiting the override input terminal, or opening the test input ter-
minal, whichever operates first.
If one of the three conditions above becomes invalid or timing ex-
ceeds 60 sec., the override function becomes invalid.
● Auxiliary output 1
Muting operation state is outputted.
When the muting function is invalid: ON
When the muting function is valid: OFF
● Auxiliary output 2
Override operation state is outputted.
When the override function is invalid: ON
When the override function is valid: OFF
● Auxiliary output 3
Blown lamp is outputted.
(When the two lamps are connected, the signal is outputted if one of
them blows.)
When the muting lamp is normal: ON
When the muting lamp is in error: OFF
(Always OFF when only one lamp is used.)
● Auxiliary output 4
The auxiliary output of the light curtain.
When the light curtain is in the light blocked status: ON
When the light curtain is in the light received status: OFF
● Interference prevention function
Max. three sets (total 192 beam channels) of the light curtain can be
connected in parallel by using the interference prevention terminals
(IE+, IE-, IR+ and IR-).

Notes: 1) The interference prevention wire for connection between SF-C14EXs should
be 0.5m or less. If the length is 0.5m or more, use ø0.2mm
twisted pair cable.
2) The interference prevention wire for connection with a unit of light curtain
should be 12-core cable.
3) Refer to the instruction manual enclosed with the light curtain for details of the
connection with a unit of light curtain.

FUNCTIONS USING HANDY CONTROLLER
SFB-HC (OPTIONAL)
● The following settings can be done with the handy-controller
SFB-HC (Ver. 2 or later) (optional).
Note that the SFB-HC (Ver. 1) cannot be used for those settings.
(Refer to the name plate affixed on the product.)
● Refer to the instruction manual enclosed with the handy controller for
details of the function settings.
WARNING
Among the functions, the contents related to the safety distance such
as the size of the minimum sensing object and response time are var-
ied depending on the setting condition. When setting each function, re-
calculate the safety distance, and make enough space larger than the
calculated safety distance. Failure to do so might cause the accident that
the machine cannot stop quickly before reaching the dangerous area of
the machine, resulting in death or serious injury.
● The information of the connected SF4B / SF4B<V2> series is stored when
the muting setting changing function / the fixed blanking function / the float-
ing blanking function is set (the number of sensors / beam channels). If the
different configured SF4B / SF4B<V2> series from that stored at the last
setting is connected, "
" is displayed in the digital display (red).
● When the muting function and the fixed blanking function / the float-
ing blanking function are set, the fixed blanking function / the float-
ing blanking function are prioritized.
● Fixed blanking function
This function enables to protect the control output (OSSD 1 / 2) from
turning into OFF even though the specific beam channel is blocked.
The factory setting is set to be invalid for the fixed blanking function.
● Floating blanking function
This function enables to protect the control output (OSSD 1 / 2) from
turning into OFF even though the number of the blocked beam chan-
nels are lower than that of the setting beam channels. One, two or
three beam channels are settable as the blocking beam channels.
The factory setting is set to be invalid for the floating blanking function.
Both fixed blanking function and floating blanking function are settable
simultaneously.
● Emission intensity control function
Emission intensity is the set value of the connected SF4B / SF4B<V2> series.
The factory setting of SF4B / SF4B<V2> series is normal mode.
● Auxiliary output 4 switching function (non-safety output)
The following outputs are switchable as the auxiliary output 4 switching function.
• Negative logic of the control output (OSSD 1) (factory setting)
• Positive logic of the control output (OSSD 1)
• For unstable incident light: OFF (Note 1)
• For unstable incident light: ON (Note 1)
• For emission: ON (Note 2)
• For emission: OFF (Note 2)
• For light reception: ON, For light blocked: OFF (Note 3)
• For light reception: OFF, For light blocked: ON (Note 3)
Notes: 1) The output cannot be used while the fix blanking function, floating blanking
function or the muting function is activated.
2) Emission halt cannot be done by using the emission halt input wire of the
SF4B / SF4B<V2> series.
3) This product outputs the light received / blocked state under activating the
auxiliary output switching function using the handy controller irrespective of
activating other functions: fixed blanking function, floating blanking function
and muting function.
<e.g.>
In case of activating the fixed blanking function, the control output (OSSD 1 /
2) becomes ON with the shielded object existed in the setting range and other
ranges are in light received state. If the auxiliary output 4 switching function
activates in No. 4 output, this product becomes OFF because the SF4B /
SF4B<V2> series itself detects the object.
● Muting setting changing function
• The setting of the muting function is changeable.
1. Output order of the muting sensor 1 and 2 can be specified so that the
muting function will be valid. When the output order of the muting sen-
sor 1 / 2 is designated, the time-lag for inputting requires 30ms or more.
The muting function will be valid either the muting sensor 1 or 2
comes first to output at the time of factory setting.
2. Select either to validate or invalidate the muting function per
beam channel. (Note 1)
The muting function is valid in all beam channels at the time of
factory setting.
3. Select either to validate or invalidate the muting lamp diagnosis
function. When the setting is invalid, the auxiliary output 3 (Blown
lamp output) (Terminal: AUX3) stays ON state.
The factory setting is valid for this.
Notes: 1) When the light is blocked on the beam channel set as the muting function
invalid while the muting function is active, the control output (OSSD 1 / 2) is
turned OFF and the muting function becomes invalid.
2) If the muting lamp diagnosis function is set to be invalid, the muting function is
maintained even if a lamp blows or a lamp is not connected.
● Protective function
Unless the password is inputted, any change in setting of the SF4B /
SF4B<V2> series is not allowed.
The factory setting is set to be invalid for the protective function.
