[Elecraft] [KPA500] 270V ERR

[LA7NO]

Hello,

We are constantly getting the "270V ERR" when switching over to OPER.
We have checked that the micro-switch is working properly and is correctly
operated by the lid.
We have also tried the power reset, but still the same.

We know there is a problem with the I/O card, since we are not able to get a
PC connected to the serial port - RS232 (PC).
So, we can not use the KPA500 Utility Program.

Is it in any way possible that a fault on the I/O-card can cause the "270V
ERR" message?
