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.
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.
 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.
Beam unblocked/blocked state
Unblocked (stably unblocked or unstably unblocked) and safety
outputs OFF.
Stable state and safety outputs ON
Unstable state and safety outputs ON
Blocked
[F3SG-SRA ABI placement example]
Beam group 1
[F3SG-PG ABI placement example]
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.
