Auto Blanking - (AB) Option
Triad's advanced "Auto-Blank" option is unique because it will
automatically blank out only the required number of beams needed to accept an obstruction such as a conveyor,
bracket or fixture. The unit is easily programmed by a supervisory controlled four position keyed selector
switch located on the front panel of the receiver pylon.The "Auto-Blank" method of blanking is much safer
than DIP switch or master/slave blanking systems because only the area of the obstruction will be blanked.
This feature prohibits unsafe oversizing of the blanked area commonly found throughout industry on manually
blanked systems. "Auto- Blank" also eliminates the need to count beams and to locate where
and what beams are to be shut off to obtain the correct beam elevation to accept an obstruction. "Auto-Blank"
will also watch the obstruction and, if it moves or is removed, will go into a "machine stop mode" to prevent
further machine operation. This is an additional safety feature not available on manually blanked units.
These features truly enhance production while providing the ultimate in
When the key switch is turned to the
"Auto-Blank" function, the "Quickview Diagnostic Display" will show the number of blocked beams for two seconds,
then verify that the obstruction is being monitored. This is required information for the depth penetration factor
and for proper installation of any safety light curtain.
