2-22. Area Beam Indicator (ABI)
2-22-1. Overview
The unblocked/blocked state of beams, internal state of the sensor, and the state of external wiring are
displayed on the Area Beam Indicator (or ABI indicators) located on the beam face according to the
setting below.
When the wired synchronization setting is applied, the ABI indicators of the emitter and receiver display synchronously.
When the optical synchronization setting is applied, the ABI indicators of the emitter always holds OFF.
Unblocked/Blocked State
The ABI indicators located near each beam is illuminated according to the unblocked/blocked state of
the beam.
The basic operation is as follows.
In the Optical Synchronization, the ABI indicators are illuminated based on the table above after synchronization is
established between the emitter and receiver. If synchronization is not established yet, the ABI indicators are not
illuminated.
For example on the figure above, if even one of the beams in beam group 1 is blocked, the ABI
indicators of that group are illuminated in red. When all the beams in that group are unblocked, the ABI
indicators are turned OFF.
After the control output is turned ON, if even one of the beams in a group enters the unstable state, the
the ABI indicators of that group are illuminated in orange.
[ABI indication in beam alignment]
For the installation of the F3SG-SR, you can use the ABI indicators to display that beam alignment is
successful.
After the F3SG-SR is powered up and synchronization between the emitter and receiver is established, if
stable unblocked state cannot be confirmed, the ABI indicators are illuminated as follows.
However, the F3SG-SR does not monitor all beams like in normal operation but monitors the
unblocked/blocked state of only some beams in the group (hereinafter those beams are called
