Blanking
4-1-2
Beam tolerance setting
!WARNING
There are two limitations for the Blanking function:
1. Maximum percentage of blanked beams out of total beams is 30%
2. Maximum number of blanked beams is 21.
The Blanking function is active as long as the beams obstructed during the
teach-in remain blocked. If the number of beams obstructed is higher or lower,
the F3S-TGR-CL system will change to ERROR state with the "LOWER" and
"BREAK" LEDs blinking. To reset this error, press and release the TEST/
RESTART pushbutton when the object is in the detection zone again.
Different pattern tolerances influence the resolution of the system and require
an increase in the safety distance. Read the following section carefully.
Machine parts or the objects that obscure the detection zone can move or
vibrate. This causes tolerances in the beam pattern.
The F3S-TGR-CL system includes different beam tolerance settings via the
selector switches to cover these requirements:
Object that can obscure one beam more than the blanked area
Object that can move along the sensing area
