Optical Synchronization

Section 5-4

5-4

Optical Synchronization

The synchronization between the MS4800 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) (8 beams +/- 1 beam

tolerance) 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.

Example:

A MS48000S-EA-014-1320 has 132 beams. In blanking application,

10 consecutive beams have to be free for optical synchronization. The

remaining 122 beams can be used for fixed blanking applications (max

8±1 beams).
