Possible Blanking scenarios

!WARNING
6
Use of Blanking will make a F3S-TGR-CL system less sensitive to objects in
the detection zone. Improper use of this feature can result in severe injury to
personnel.
Blanking may require an additional hard barrier guard.
Blanking may require an increase in the safety distance. Read the following
section carefully.
A selectable number of optical channels can be obstructed at any location in
the detection zone as long as the optical synchronization is maintained. The
beam opposite side to the connector end-cap is used for optical synchroniza-
tion and cannot be blanked.
An object can freely float from one end of the protective field to the other with-
out the F3S-TGR-CL system entering the MACHINE STOP state. The
obstructed channels are not fixed at a single location but "float" through the
detection zone. It is possible to have multiple blanked areas of different sizes.
Setting of Blanking is done by a teach-in.
Example using additional mechanical guarding:
Where
A = additional mechanical guard
B = machine part that permanently blocks 3 beams, eg. a support table
All three situations will lead to a valid Blanking condition. Please check your
application carefully. Failure to do so may result in serious injury.
The F3S-TGR-CL system is monitoring the number of blocked beams. The
position of the object(s) is not monitored.
