ANNEX1 INDEX
Terms Explanation
Auto reset mode
[F3SN,
F3SH]
Interlock function is invalid in this mode. This mode can be
selected with wiring interlock selection input and reset input.
This mode voids all, despite the setting value of start/restart
interlock function.
A
Auxiliary output
[F3SN,
F3SH]
Non-safety related output used to display a status.
This output cannot be used for the purpose of safety.
Blanking monitoring
output
(Auxiliary output, output2)
Output ON when the blanked beam becomes light
reception-state, when the fixed blanking function is valid.
B
Blanking setting
(Ext. indicator)
Output ON when fixed blanking function or floating blanking
function is effective.
D Dark ON
(Auxiliary output, output2,
Ext. indicator)
Output ON when sensor detects objects. In case series
connected, output ON when one or more sensors detects
objects.
External indicator output Non-safety related output which can be connected to an
optional indicator.
Applicable only to the models which can be connected in series.
E
External device
monitoring
[F3SN, F3SH]
This function can detect malfunction of external device which
controls hazardous area of machine. (e.g. contact welding)
Fixed blanking function
[F3SN,
F3ZN]
Partly voids detection zone of sensor. Entrance of object into
blanked detection zone does not change output condition.
F3SN: 1. Fixed blanking function becomes invalid when blanked
zone becomes clear, or lockout condition. Fixed
blanking function becomes valid again, after power has
reset.
2. It becomes lockout condition when blanked zone
becomes clear. Fixed blanking function becomes valid
again, after power has reset, or reset input.
F3ZN: Fixed blanking function is valid even after blanked zone
becomes light reception-state.
F
Floating blanking function [F3SN,
F3ZN]
This function allows the output to remain ON when beams of
the sensor are interrupted anywhere in the field.
Floating can be set for 1 to 3 beams.
I ID
Indicates numbers 0000 to 9999 which can be set specific to
each sensor.
L Light
diagnosis
(Auxiliary output, output2,
Ext. indicator)
Output ON when unstable condition lasts for 3 seconds or
more.
Can detect deterioration of optical performance caused by dirty
optical surface, displacement of beams or deterioration of LED.
“Unstable condition” indicates that the light level remains within
+/-20% of threshold value.

Terms Explanation
Light ON
(Auxiliary output, output2,
Ext. indicator)
Output ON when detection area is clear. In case series
connected, output ON when all sensors’ detection area is clear.
Lockout output
(Auxiliary output, output2,
Ext. indicator)
Output ON when the sensor is in lockout condition (i.e. mode
which detects abnormality and stop the sensing function).
Lighting pattern setup
The lighting pattern of external indicator is set up. A default is
"lighting." The blink cycle can set up 0.5 seconds, 1 second,
and 2 seconds.
Manual reset mode
[F3SN,
F3SH]
Interlock function is valid in this mode.
This mode can be selected by wiring interlock selection input
and reset input.
Max. number of fixed
beams
(Protect)
Maximum number of beams which can be blanked by fixed
blanking function. Beams exceeding this number cannot be set
blanked.
Max. number of fixed
zones
(Protect)
Maximum number of set of beam(s) which can be blanked by
fixed blanking function.
One zone is defined as blanked beam(s) which is surrounded
by not-blanked beams.
M
Max. number of floating
beams
(Protect)
Maximum number of beams which can be set by floating
blanking function. Floating beams exceeding this number
cannot be set.
Outermost beam invalid
(Floating blanking)
This mode excludes outermost beams from floating blanking.
When this mode is valid, the output will turn OFF if one of the
outermost beams is blocked, even if floating blanking is active.
Outermost beam
monitoring output
(Auxiliary output, output2)
Output ON when only outermost beam(s) is/are interrupted.
O
Output2 [F3ZN]
Output of F3ZN used to display a status.
R Restart interlock function [F3SN,
F3SH]
Outputs remain in the OFF-state (i.e. interlock state) when
sensor is interrupted. Interlock state can be released by a
manual reset when there are no obstructions in the detection
zone.
This function is valid only when using manual reset mode.
Sequential beam mode
(Floating blanking)
If this mode is valid, output becomes OFF when consecutive
blocked beams exceeds floating beams.
If this mode is invalid, output becomes OFF when sum of
blocked beams exceeds floating beams.
S
Specified Beam
(Auxiliary output, output2)
Output ON when any of specified beams are blocked.
When this signal is selected, it is necessary to specify beam.
