Hello guys!
My favorite lift in my warehouse is now broken. Everything happened while I was driving thru small speed bump on the parking lot and speeding pretty much cause in hurry it feels like whole lift jumped in the air for a second. Then power supply went off for a second and came back again with many fault codes on the display...
I spent almost whole week of my free time to investigate what could be the problem but I can't find anything wrong with hardware... I checked fuses, switches, main contactor, cables, sensors and battery but everything looks fine. On all three CPU boards AS4812/14 red diode is flashing but I could't see any damages on it. I measured transistors as well all looks fine...
I'm getting ALARM 39 with different infos:
- ALARM 39 LIFT
- TRUCKTYP
- ALARM 39 INT3
- ALARM 39 TRACT
and sometimes:
- INTERFACE/CAN
I know we have experts with large knowledge here so I'm begging for help.
Found someone with same problem somewhere on this forum and it seems to looks like configuration lost that need to be done with Jungheinrich JUDIT interface but nothing I'm sure about.
Thank you for your time!
