You can either mask it or look at it as an EMI issue and see if you can trace the source Those error messages look like somehow turning off the power has generated enough EMI to generate a false character in the serial link. My first suspect would be arc/contact HF noise from the main contactor. A snubber across the contacts may help this Stopping the sserial channel on estop should mask this > > ------------------------------------------------------------------------------ > Live Security Virtual Conference > Exclusive live event will cover all the ways today's security and > threat landscape has changed and how IT managers can respond.
