Minimizing interference from radiated electrical noise:
•
Isolate signal wiring (such as LVDT input cables) from power lines and
sources of electrical noise (such as motors and proportional amplifiers).
•
Use shielded twisted pairs for all input and output connections.
•
Make cables and unshielded leads as short as possible.
•
Connect the shields of LVDT input cables and drive-output cables to earth
ground at the I/O chassis at the nearest chassis mounting bolt.
•
Ground cable shields at one end only.
•
Connect all of the following to earth ground:
– power supply cable shields
– LDT flange, frame, and machine
– I/O chassis
– a/c ground
•
Place the SLC processor and I/O chassis in a suitable enclosure.
