General Mounting Considerations
Section 10-3
10-3-3 Installation of Multiple Systems
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 mount-
ing the transmitters and receivers back-to-back or stacked.
The scan code 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 sys-
tem with a different scan code. Two unique codes are available on the
MS4800.
10-3-4 Detection Zone
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.
10-3-5 Alignment
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 part of the Safety Light Cur-
tain is out of alignment.
10-3-6 Input Power Requirements
The system operates directly from 24 VDC ±20%. Power to the system must
come from a power supply which meets the requirements of EN/IEC60204-1
and EN/IEC 61496-1.
The power supply must guarantee safe insulation from the mains voltage in
accordance with IEC60742 and be able to cover a drop of supply voltage of at
least 20 ms. Omron offers suitable power supplies. The power supply must
not supply any other parts of the machine with power other than the safety
components connected. Transmitters and receivers must be supplied from a
shared power supply and must be fused against overcurrent.
