APPENDIX A: TROUBLESHOOTING ELECTRICAL INTERFERENCE
PROBLEMS
Electrical interference problems are common with today's computer -
based controls, and such problems are often difficult to diagnose and
cure. If such a problem occurs with your system, the following checks
should be made to locate the cause of the problem.
1.
Check the quality of the ac line voltage using an oscilloscope and
a line monitor, such as the Superior Electric VMS series. If line
voltage problems exist, use appropriate line conditioning, such as
line filters or isolation transformers.
2.
Be certain proper wiring practices are followed for location, groun-
ding, wiring and relay suppression.
3.
Double check the grounding connections to be sure they are good
electrical connections and are as short and direct as possible.
4.
Try operating the drive with all suspected noise sources switched
off. If the drive functions properly, switch the noise sources on
again, one at a time, and isolate which ones are causing the inter-
ference problems. When a noise source is located, try rerouting
wiring, suppressing relays or other measures to eliminate the
problem.
