Message E1514 indicates faulty display, however it could be that the CANbus system is open, and the display is the first component. Check the “T” which should be moved to the load pin . In this case the pins were bent on the Anemometer, and needed replaced.

Liebherr 81k.1 Radio Remote Receiver
The cord for the antenna got cut and we could not get the receiver to send out a signal. It has power but on the front of the receiver, there are LED lights. We had power but not the second light down. It is red until it hooks up with the remote then it goes green. We called HBC and they had us remove the cover and check all the fuses there is a very small 1 AMP fuse shown in the picture. It had a red led next to it which meant it was blown. We soldered a jumper with a 5 amp fuse around it and it all worked.
It doesn’t matter what length the antenna cable is for connecting to the remote.
Liebherr 81k.1 won’t swing or trolley
The operator called and said the crane would not swing or the trolley have him send a picture of the remote. IT had E 39 on it. Looked it up and found that it was in the forbidden zone. Had to turn key for zoning in the side panel to override the zoning and drive the crane out of the zone then switch the key back to make sure the zoning was back on.
