Fixed Blanking Rules
Tabl e 62 shows the rules for fixed blanking within a zone. The Connected
Components Workbench software automatically enforces these blanking rules.
Since the transceiver sticks are synchronized with either the first or last lens, only
one end of the stick can be blocked (not both ends).

Teach Blanking Zones
The Connected Components Workbench software can learn new arrangements
of fixed blanking. It learns by reading the beams, storing the new setting in a
project, and then transfering the new settings down to the light curtain. Follow
this process:
1. Set up the fixed object within the light curtain field.
2. Connect the Connected Components Workbench software to the light
curtain.
3. Teach the Connected Components Workbench software the new settings.
4. Download the new settings to the light curtain
5. Upload and confirm (lock) the new settings.
