Two Types of Blanking Functions
Blanking functions change the Safety Light Curtain detection patterns.
Basic Pattern 2: Fixed Blanking
Uses a teaching technique to mask and disable
specific beams. Ideal for applications where part of a
machine or jig is always inside the fixed detection
zone of the Safety Light Curtain.
Basic Pattern 1: Floating Blanking
Disables detection for 1, 2, or 3 non-specific beams.
Output is turned OFF if more than the specified
number of beams are obstructed. Ideal for applications
where a robot arm for removing workpieces passes
through the Safety Light Curtain detection zone at
irregular intervals.
Auxiliary Output:
Can select outputs such as Dark-ON,
Light-ON, Light diagnosis, and Lockout.
External Indicator Output:
Can select external indicator output from Dark-ON,
Light-ON, Light diagnosis, and Lockout.
EDM (External Device Monitoring) function:
Monitors for external relay contact welding.
Interlock Function:
Sets interlock for when power is turned ON or the system is restarted.
Copy Settings Function:
Copies Sensor settings to another Sensor.
Protect Function:
Prohibits or limits changes to Sensor settings.

Other Function Settings from the Setting Console
There is a danger if fixed blanking
is not used because a hand
could enter under the
light curtain if the work
bench shifts out of
the zone.
If fixed blanking is used and the work
bench is removed, fixed blanking
will be canceled. If, for example,
a hand enters the area,
it will be detected and the
output will be turned OFF
for safety.
A protruding part fixed on a moving
die moves up and down within the
detection zone.
