Discussion:
Error 31 - Potentiometer ?

Hello,

I have a problem with a Linde L12 - 379.
Everytime you start the truck an drive forward, the machine will operat normal. But if you want to drive back, it could happen that machine won`t drive. But only sometimes, it also could be that the truck works normal.

I have seen the Error 31 with Truck Doctor. I Changed the potentiomter (only the poti, not the hole unit) but it isn“t better. Sometimes it works, sometimes not.

Somebody any ideas?

Thanks a lot. Tom

Marco, i have a L12 364 battery light shows full power, key works and micro switch at the bottom of the handle just onto the drive motor works. I have no power or it seems to have no power to function anything from here, so i can not move or lift or anything. Seems like a emergency STOP switch somewhere, i am new to the machine so is there one on the grab handle? I have a multimeter just not sure where to start.
Thanks!!

I assume your trouble consumer call of windows, we see equal trouble whilst pc consumer call set turkish characters. Exactly this indicates the communique among consumer and server is lost. Is the consumer supervisor strolling on equal PC with server?

Hi !

Check your tension in the middle of your potentiometer: 4.6 Volt is exatly to calibrate correctly.
