Because of this restrictions, when programming a fixed or monitored blanking object(s), the size of the
fixed or monitored b lanking object(s) must comply with the number of consecutive clear beams stated
in
Table 4-9
within the first segment.
In addition to that, there must be at least one (2) clear beams on each flex segment.

All MS4800 systems have a visible, red, Individual Beam Indicator (IBI) adjacent to each infrared
beam. These IBIs are located on the receiver. The IBI will light when the infrared beam fails to meet
the conditions necessary for the system to remain in the MACHINE RUN state. When less than 10
consecutive beams are clear, every other IBI will light indicating that the MS4800 is not synchronized.
IBIs are not a safety critical component. An IBI failure will not cause an alarm condition and the
system will continue to operate.

EDM is not available on the 5-pin version of the MS4800. If external device monitoring is required,
OMRON STI recommends the use of a safety monitoring relay in conjunction with the MS4800 light
curtain.

The MS4800 offers operating range selection: short range is 8m and long range is 20m. This function is
useful when there are many light curtains operating within a small space and the possibility of cross-
talk is likely.
