I have a tac 20 2 stop with some Lon trouble. Bottom floor push button not working. Spi loop says ok in Lon explorer LN board in hoistways has a slow steady blink. Swapped the top and bottom L24 boards and still same problem. Both l24 cards worked at the top floor but neither work at the bottom. Tried putting car on fire service elevator recalled but now won’t reset off of fire service? Tried I/o injection to memic the phase 1 key switch but car seems to be stuck on fire service.
Any ideas on how to get it of phase 1 so I can continue troubleshooting my button problem. It seems like the controller is not seeing all the I/0s at the main landing?
