5-4
Optical Synchronization
The synchronization between the MS2800 system transmitter and receiver is
optical, so the system does not use one specific beam. To establish synchro-
nization the system needs to have a certain number of consecutive clear
beams (see following table) within the first master segment. If they are not sat-
isfied, the system will enter a MACHINE STOP state and every other Individ-
ual Beam Indicator will light. When the beams are cleared, the system will re-
synchronize itself and enter a state consistent with its operating mode. Once
the synchronization is established, it can be maintained as long as the
required number of consecutive clear beams can be satisfied anywhere in the
system (including flex segments).
Because of these restrictions, when programming a fixed blanking object(s),
the size of the fixed or monitored blanking object(s) must comply with the
number of consecutive clear beams stated in the previous table within the first
master segment.
In addition to that, any fixed or monitored blanking programming must be done
with at least one (1) clear beam on each flex segment.
