Thanks in advance. Otis 211 Phase 2, it is in fault fslr, the selector signals are good in the I/O board, i need to change some parameters but when i reset the controller the parameters go to preview number.
No Service Tool can talk with the elevator ( i dont know why) i have tested four diferent Service Tool in both elevators.
So, how to put in off the write protection from the controller, i suppose it is what avoid to change the parameters.
