I'am trying to repairing a controller DR90-A01 and one issues error code or what I think is an error code. Can not see in the manual what the error code is?
Are there any special codes that anyone here recognizes?
The direct thing I know is wrong is the 15 volt rail does not provide output voltage. It may also explain why it is not possible to connect to the wizard program.
Sends with a video showing the LED.
