I'm having trouble with a TAC 50 car intermittently tripping NTS and ETS faults. The faults happen at the terminal floors about two or three times a day. So far the DSP Board, and NTS/ETS sensor, and modules have been replaced. The NTS/ETS sensors have also been switched to shielded wire from regular traveler wire. The hoistway has been relearned and NTS/ETS switches have been relearned after all items were replaced. Does anyone have any other ideas to try to fix this issue. Thanks.

Just incase any one was interested, it ended up being the PMI 1 board. Of course, it was the last thing to replace.
