Electronics housing
The sensor unit of the measuring system (excluding AMSA 3L) has a separate electronics
housing. The electronics housing is mounted near the read head at the machine slide
and has an LED display on its front for indicating various operating states.
The electronics housing should be installed in accordance with the following points:
• Fit the electronics housing so that the front of the housing and the diagnostic LED
(in the case of AMSD 3B/4B, AMSABS 3B) are easily accessible for servicing.
• Do not lay cables from and to the housing under tension.
• Do not fall below the minimum bending radii (see „12.4 Cable bending radii" on
page 76).
Cables
Shielded cables are used as KAO extension and connecting cables between
the measuring system and controller.
When laying cables for the measuring system, the following points must be observed:
NOTE: Do not lay cables next to interference sources, e.g. magnetic fields from voltage
supplies, mains electricity lines, motors, valves, relays and their feeds.
• For cable conduits, ensure that the dimensions of the mounting base comply with
the catalogue or connector diameter.
• Ensure an adequate distance from cables carrying interference sources: 0.1 m.
• Employ a grounded separation screen if metal cable ducts are used.
• Ensure a minimum distance of 0.2 m from storage chokes in switched mode
power supplies.
• Separate hydraulic hoses and electrical cables.
• Lay the read head cable (4) as statically as possible, e.g. not in a cable carrier (6).
• Use an extension cable (5) as a cable carrier (6).
• Do not use sharp-edged ducts.
• Lay cables without any tensile load.
• Do not fall below the minimum bending radii (see „12.4 Cable bending radii" on
page 76).
