    keyword=Electron Arm VDC power supplies.

    I looked at the Electron Arm VDC Slow Controls. After restoring all the power
    supplies to their original configuration I verified the EPICS DAC control is not
    functional. It seems to be a problem in the EPICS driver for the DAC. Further
    investigation is ongoing. The threshold supplies are in local control mode and
    set to about 4.0 volts. The high voltage supplies are in local control and set to
    about 4.0kV. The voltage readbacks through the ADC in the Slow Controls are
    hooked up and working. The Electron Arm VDC high voltages should not be
    reset, in the event of a current trip, without first contacting Jack Segal or Bogdan W.
