Schindler 330a problems

This 330a is stuck in AST mode. I can run the elevator on inspection but it will return back to ast every time as soon as I switch it to automotic. When I reset the elevator controlls it also goes back into ast mode before it even tries to run. I checked the emergency terminal limits and everything is ok. The faults are a 107 pit oil switch, which this elevator does not have and a 1209, missing node. I checked the nodes on the smlcd and they all test out ok. Does anyone have any ideas why this elevator will not come out of ast mode?

Did you do the double re-boot? If that doesn't work, you may need to drain the super-cap.

I had similar problems and it was bad mother board

I did not do a double re-boot. How is this done and what does it do?

Push button on the perpendicular board to the right of mother board ... push once then lights will flash then push again while lights are flashing.

The double re-boot worked! Thanks guys for your help.

Had a similar situation that would repeat once a week at first then every day after a while. Turned out the be a bad t cable wired in a shielded pair.
