Still EXU 20 AC

Hello,

problems with EXU 20 AC Curtis controller (error flashes 4-2 times).
Vehicel moves very slowly,
Replaced controller some months ago and everything worked fine.
Now same problem.

Any body how can help me with the Curtis flashcodes? They are not in the Still service manual.

thanks for the reply,
@nemanja: te 1243 controler is a DC Sepex controller, not a AC controller.
The controller in the truck somthing like he 1222 controller on the Curtis website but the big connection is on ront of the controller, not on top (special made for Still i think)
Should the faultcodes always be te same on the Curtis controllers?

@elektrodrive: Thanks for the info, but the AC controller have only product info, no faultcodes :(

Regards Fritz
