Looking for information or solution to getting "normal" operation from Premium display.

I installed a new Controller (GE) and premium display unit on this hyster E50XM2 and now I can only get a very limited amount of information from the display "BATT ADJUSTMENTS NOT ALLOWED" and ACTIVATE FAULTS.

Customer would like to have the normal display with power settings, BDI and hours read out.

Any ideas on how to make this happen??
