Attached is a 5 minute plot of the monitor signal for the current of diode box 3.  The initial reported value of 50.14 A is
corrected.  ~44 seconds after the start of the plot, the monitor signal hits 100 A.  Whilst the switching from the true value
to the false value was going on, the error bit on the corresponding Beckhoff terminal did not change state from 0 to 1.  The
output value changed from ~12460 to ~24880 counts.

    Since an ADC most likely does not change its reported value unless the signal it is monitoring changes, the problem would
seem to lay with the output monitoring signal of the power supply.  Without knowing what is in the output monitoring circuit of
the power supply, the problem I have is explaining why it resets itself after a period of inactivity unless it is a temperature
related fault.  The evidence for it being temperature related is purely circumstantial at this stage.

    I would suggest that the power supply be switched out.
