new install accenta 8SP399A. Constantly gives tamper lockout though wiring is correct. Message reads on top line 1-8 followed by TP, and the bottom line is 8 zero'es followed by FO.
I can get into engineer mode and change things but on exit lockout still exists. Comms not used so wonder if terminals should be linked out in some way though the book doesn't mention that.
I am looking stupid here so hope you can help.

and check the tamper strech springs on the main panel and on the keypad make sure tamper is wired correctly
