You need to re-program Drop the front panel, flick switch on the board to program. You will then be able to drive the lift (stop the lift when both copper charge plungers are central on the charge point) to the top charge point, this will reset the datum
Drive the lift off the charge point, flick the program switch off and now the lift will remember its old program
This will get the lift running but I recommend you get an engineer in to check final limits etc are programmed
