Local the 1078 is a low RAM battery fault. The other 2 faults are MCD and MCE contactor faults. CPU could be the culprit here with that bad battery. Start there, the MCD and MCE are both on the first or second page of the prints, 2 AC relays I believe, EPEN I think is the one I would start with.

Also worth noting, the Siemens starter board has a very short life span. I give those boards to service guys as soon as I get them, the 7-8 normally closed ready, and 9-10 normally open ready fail. TKE used to repair them, bad resistor if I remember correctly, but has found its actually just cheaper to swap for new.

Holler back if this didn't help you get on the right page to fix it, I am on TAC 32's now for new installs, but I can swing by an old 20 and look some stuff up if you need it.

Forgot to ask, does this elevator have UPS for the battery backup? I have heard of a few ghost faults when these batteries begin to go bad.
