Hi Everyone

The problem is the display when switched on just shows the letters Pin, and nothing happens. We know its a display problem as we have replaced the display off another truck and the truck works.
What I wanted to know is has someone come across this problem before where a display just shows these letters and locks the truck out from being operated? The truck was working fine until one day they came to switch it on and this is what appeared on the display. Linde dont seem to know what it stands for according to the linde engineers.
