New member here- Thanks for having me! So long story short we have a TAC 32 in a school - 3 floor, single cab system that suffered a power outage. Initial symptoms - motor would not energize, no hall call or in car response to any buttons (not even a momentary light). Checked all the fuses, pulled power and the 3v battery, restarted it, reloaded the USB flash. After that things improved a bit. Motor energized, we could move it on inspection mode-but not through the tool. No response from cab buttons (reset board in cab) WE could manually open the door and when it would close the curtain would stop the door, but not open it back up...

Fast forward a bit Reinitialized some things using the RemoteFAST and now here we are... can go to all floors in the cab now, doors work properly, main floor with Up and down call buttons works properly-- lights up, calls the cab... However on the top floor- no call call light at all when pushing the button, same on bottom floor- no call light and the car stays put. Not seeing any power at the HC button, but we are getting power to the key switch (green LED)


Checked the boards in the chaseway and reset all 3, and still the same issue We are getting a green light on the boards and the fuses check out. On the UIT we are pulling errors 1125-1128. They pop back up right after clearing them. I personally think it is one of the boards in the chaseway, but with 2 seperate floors out it makes it a little odd.

Any thoughts on this?--Or questions.
