C5 control panel problem
Suddenly green lights on height control panel turn off.
I check and it is error whit communicating with the control panel.
01776 - Control Head for Level Regulation
37-00
I replaced the driver, the error is still.
I replaced the control panel, the error is still.
I checked electrical conductors from the control panel to the controller and everything is OK.
someone has an idea where to look for solution ???
(sorry for my English)
