Configuration Options
On the configuration window, blanking has three types that can be selected
when the Connected Components Workbench software is disconnected from
the safety light curtain:
•
Disable – blanking is not used
•
Software configuration – configure for fixed, floating, or reduced
resolution
•
Push Button Teach-in – use the Teach command button on the Diagnose
Window
Fixed Blanking
A fixed blanking zone is a set of lenses that has been configured to always
expect an object to block the beams. The beams must always be blocked. A fixed
zone that becomes unblocked causes the OSSD outputs of the light curtain
receiver to turn OFF.
The Bulletin 450L-E safety light curtain accommodates changes in the set of
lenses that can be blocked; this change is the object tolerance. The object
tolerance can be set to zero (no lens tolerance) or to a negative number. The
fixed blanking range can only be smaller by the tolerance number. A positive
shift in the object size or location causes the OSSD outputs to turn OFF.
The Bulletin 450L-E safety light curtain uses the first or last beams for
synchronization. If the first beam is blocked, then the last beam cannot be
blocked. In contrast, if the last beam is blocked then the first beam cannot be
blocked.
