I have a tac 50 elevator that takes itself
out of service on the bottom
terminal level producing 813 & 690 faults.
It also faults the DSP board out and red solid red light stays on.

Only way to get it to reset is
to power down then power back up then run car to next floor up on insp service.

Then it can stay in service for as little as the next day or as long as 3 weeks.

Has anyone else have had this problem?
