System Operation and Functions
 Fixed Blanking Monitoring Function
For safety reasons, F3SG-RA transitions to lockout state* if part of a fixed blanking zone is unblocked.
(Factory default setting.)
When the F3SG-RA is set to Blanking Zone Cancelled, the fixed blanking function is cancelled if part of
a fixed blanking zone is unblocked.
In this case, power cycle enables the fixed blanking function again with the same setting as previous
one.
Turn off the power and on again while all fixed blanking zones are blocked.
Setting to Monitoring disabled disables the blanking monitoring.
* Allowable beams configured on both ends of fixed blanking zone are not monitored.
 Allowable Beam
Allowable beam represents a beam out of the target of fixed blanking monitoring. This should be
configured for a fixed blanking beam that is irregularly blocked and unblocked due to an interrupting
object's oscillation. An allowable beam can be assigned to the beams on both ends or one end of a
fixed blanking zone.
If a fixed blanking zone is configured by teach-in with DIP Switch, the 2 upper and 2 lower beams of
the fixed blanking zone are configured as allowable beams.
For allowable beam setting with the Configuration Tool, refer to the user's manual of the Configuration Tool.
Safety Light Curtain Configuration Tool for Model F3SG (SD Manager 2) User's Manual
See below for an example.
In this case, 5th, 6th, and 10th beams are set as allowable beams. These beams is repeatedly blocked
and unblocked due to an interrupting object's oscillation. But because these beams are not the target
of the monitoring, the F3SG-RA keeps the safety outputs in the ON state.
