Thank you !
I know one is the multipilot.
one is main board (motor is OK).
one I exchange the multipilot frome another,it's OK.(the cable to the valve is break)
One exchange the main board,also OK


Could you give me this type the error list?
if next time they will display another error.

Best regards

Kun

Hello.
"Electrodrive" is right. It is the older mosfet combi controller.
Error:
42. Shortcircuit on output stage
43. Error in multipilot/joystick. Centervoltage not OK. Wiring or
poti broken.
46. No field current. Bad/burned controller.
47. Minimum field current not OK.
38. Check main contactor. This error is normally related to
other errors. Safety !!!
34. No communication with controller....
27. Unknown to me. Is not in my error list.
10. Multipilot activated during start up. It is proberly a bad
poti inside multipilot (or broken wire to multipilot)

All this errors seems a litle strange since they are not related. Check for humidity and dirt on all pcb's. Check connections on hydraulic controller (top pcb on power-steering) and use LISA to check if multipilot is OK.

Sounds like the MP616 or 614K controller. Jungheinrich soon moved away from these i have been told, due to the problems with them. I would guess due to the number of error codes that are being displayed, its a good chance the problem is in the main pcb which covers both traction and lift.

Hi Trevb

it have a larger printed board of steering,above it it is the hydraulic valve controle board.Tractor and pump in a larger board,under it is some FET model.

what type of controllers do you have
