Safety-related Functions
Interlock Function
The auto-reset mode and the manual reset mode are wire selectable
features of the F3SN-A/F3SN-B/F3SH-A.
Auto-reset Mode
After the power is turned ON and none of the beams are interrupted,
the OSSD (Output Signal Switching Device) outputs will go to their
ON-state.
Manual Reset Mode
For the factory setting, the start/restart interlock is selected in the
manual reset mode. When the light curtain enters the interlock
condition, it keeps the OSSD outputs in the OFF-state. Even if all
beams become free, the OSSD outputs will not go to the ON-state.
When none of the beams are interrupted in the detection zone,
applying the reset input resets the interlock condition and the OSSD
outputs go to the ON-state.
Diagnostic Functions
Self-test
After power ON, the F3SN-A/F3SN-B/F3SH-A performs a complete
self-test within 1 second. In addition, it performs a self-test (within
response time) periodically during operation.
External Test
This function stops the emission of light from the light curtain using an
external signal and checks that the light curtain operates properly.
Lockout Condition
If an error is detected by the self-test, the light curtain enters the
lockout condition, keeps the OSSD outputs in their OFF state and
displays the error mode. Lockout condition can be cleared either by
resetting the power or by changing the setting of the reset switch from
closed to open (open to closed for auto-reset). (With some errors, the
lockout condition is automatically reset when the light curtain confirms
that the cause of the error has been removed.)
• Start/restart interlock
• Start interlock
• Restart interlock
After the power is turned ON, or when at least one beam is
interrupted, the light curtain enters the interlock condition.
Only after power ON, the light curtain enters the interlock condition.
Only when at least one beam is interrupted, the light curtain enters
the interlock condition.
Fixed Blanking Function (F3SN-A only)
This function is set with the F39-MC11 setting console.
This is a function provided to disable a specific area of the light
curtain’s detection zone. Fixed blanking can be set for any desired
number of beams. If an object enters the disabled detection zone, the
OSSD outputs status will not change. This function is used when
there is a stationary object in the detection zone that needs to be
ignored.
Floating Blanking Function (F3SN-A only)
This function is set with the F39-MC11 setting console.
During normal operation when floating blanking is disabled, and at
least one beam is interrupted, the light curtain will go to the OFF-state.
However, using this function prevents the light curtain from going to
the OFF-state until multiple beams (*1, *2, and *3) are interrupted.
*1. The number of the floating blanking beams can be selected in the
*2. This function can be set to be active only if the interrupted beams
*3. This function can be set so that the top and bottom beams cannot
EDM (External Device Monitoring)
This function monitors the state of the NC contacts. Connect the NC
contact of the MPCEs to the EDM input line of the receiver. If the
correct logical relationship between the OSSD outputs and the EDM
input is not kept, the light curtain immediately enters the lockout
condition and the OSSD outputs will go to their OFF-state.
The light curtain’s normal operation is up to 300 ms max. (*), this
allows for the delay time caused by the release of the MPCEs.
To ensure the correct usage of this function, the MPCEs must be
safety-certified types with forcibly guided contacts.
When the EDM is not used
In the case the EDM input is not used, connect the auxiliary output in
the Dark-ON output mode to the EDM input line, or disable the EDM
with the F39-MC11 setting console.
* The value can be changed by the F39-MC11.
(It is impossible to connect the F39-MC11 to the F3SN-B.)
