Hi everyone

I got a 3 stop front and rear opening Schindler 2007 hydro .. I think Its a 330a or EIB.

After a double reset it will accept a call and take off. It will land and the doors will open and close but it will be shut down on a 0121 extra info all 0 until 7B at the end. I don’t see 7B extra info on my fault list. But i do see 78. Any help on this would be great. Also if I stop the car mid flight with controller inspection it will also throw the 0121 fault after I turn it back on normal operation

Note .. top of car switches look good. All lights go on and off as I wave my hand through the horseshoes . KLU AND KLD both are lit back on controller as it stops at the floor

look like 7B is wrong should 78 (maybe-maybe not)

Thanks no time. I see the leveling zone relay clicking on the crip board. But maybe it needs to be replaced. It’s not removable. So I guess I will bring in the whole board to repair shop

Does any body have any input on this. I wish my extra info made sense. 7B??

Do you have the books for this? PM me if you need them

If your getting your crip board sent out, have your sdoor, spoor 20, cdoor, and cdoor 20relays replaced too. Those are a pretty common failure point

I have the books. But my extra info is 7B. I don’t have 7B on my list

121 78 is level zone relay in wrong state after car stops. So your original thoughts are correct. Get a new relay on the board. I'd recommend changing the CD1,CD2 SD1 and SD2 as well while they have it

It really looks like a B. Not an 8. That’s what’s confusing me. It’s def 7B. Not 78
