With all of the Beckhoff attempted repair work this morning, the ETMy ESD "railed" with all 5 channels reading ~-15k.   I went down to EY and did the Push RED ON/OFF button, unplug far right DAQ cable, Push RED ON/OFF back ON button, replug DAQ cable in procedure.  This worked - the DC bias channel is back to ~-32k while the other 4 channels are near zero at ~-200 as viewed on the lower right of the ETMY SUS screen.
