9.3.3
When two or more MS4800 systems with the same scan code are mounted in close proximity and in
alignment with each other, precautions should be taken to avoid one system interfering with another.
This can be corrected by mounting the transmitters and receivers back-to-back or stacked.

Figure 9-8 Multiple Light Curtain Installation Configurations

The scan coding feature of the MS4800 system allows for placement of systems in close proximity and
in line with each other. The distinctive coding of the beams provide for unique operation of a system
while in view of another system with a different scan code. Two unique codes are available on the
MS4800.

The system detection zone is delineated by the inside edge of the transmitter and receiver endcaps. The
area outside these marks is not protected. Position the system so that it is only possible to access the
danger point through the detection zone.
A
9.3.5
Physical alignment of the transmitter and receiver is easiest when the system is in the automatic start
operating mode with Fixed Blanking inactive. The units should be in the same plane and at equal
height.
The Individual Beam Indicators will light when a beam is out of alignment. See Section 5.1 --
Individual Beam Indicators for details.

9.3.6
The system operates directly from 24 VDC ±20%. Power to the system must come from a 24VDC
SELV power supply which meets the voltage interruptions and dip requirements of IEC 61496-1 (per
section 4.3.22 and 5.4.3.2) and IEC 60204-1 (per section 4.3.3) , Omron STI part number 42992 or
equivalent.
