I have a situation where a number of Micromint Domino 1A (8052 based) CPUs just stop while otherwise operating perfectly normally. They start up correctly after being power cycled. Units that work fine in one area of the plant stop when placed in certain trouble areas of the plant. Conversely, units that keep stopping work fine in the good areas of the plant. We have tried simulating noise with flourescent lights, universal motors, and soleniods in parallel with the input power. We have also looked at grounding issues but find nothing remarkable. The units are not near noise makers such as VFD drives, or high horsepower motors. Any troubleshooting ideas are much appreciated.
Thanks,
