Summary
Notes
1 External test
This function stops light emission of an
emitter.
2 Start interlock
After power ON, the OSSD outputs keep in
the OFF-state even if no beam is inter-
rupted. Resetting makes the OSSD outputs
go to the ON-state when all beams are in
light reception state.
3 Restart interlock
Once a beam is interrupted, the OSSD out-
puts keep in the OFF-state even if all beams
become free. Resetting makes the OSSD
outputs go to the ON-state when all beams
are in light reception state.
Wiring for manual
reset mode is
necessary.
4 Fixed blanking
This function makes detection capability of
one or more beams invalid. Even if the
specified beams are interrupted, the OSSD
outputs keeps in the OFF-state.
5 Floating blanking
When more beams are interrupted than the
specified number, the OSSD outputs go to
the OFF-state. Up to three beams can be
specified as floating.
6 EDM
(External device
monitoring)
This function detects a failure of an external
device such as a relay or contactor. If the
feedback signal from the external device is
not correct, the F3SN enters lockout condi-
tion.
7 Dark-ON output mode
(Auxiliary output)
The ON/OFF-state is inverted from the
OSSD outputs state. This mode is the de-
fault of the auxiliary output.
8 Light-ON output mode
(Auxiliary output)
The ON/OFF-state is the same as the OSSD
outputs state.
9 Outermost-beam
monitoring mode
(Auxiliary output)
When only either outermost beam is inter-
rupted, the output goes to the ON-state.
10 Lockout
mode
(Auxiliary output)
When the F3SN enters lockout condition,
the output goes to the ON-state.
11 Light diagnosis mode
(Auxiliary output)
When unstable light reception state or un-
stable interrupted state lasts for three sec-
onds or longer, the output goes to the
ON-state.
12 Specified-beam
mode
(Auxiliary output)
When any of specified beams is interrupted,
the output goes to the ON-state.
13 Blanking monitoring
mode
(Auxiliary output)
In case that the fixed blanking function is
valid, the output goes to the ON-state when
a blanked beam becomes light reception
state.
