Getting the channels sensed and in the frames show noisy pressure sensors at EndX.  Comparing the same channels to EndY I see about 6x more swing of the data signal.  I moved the EndX controller to manual and the pressure noise remained constant.  See the first plot where the drive to the motor goes flat when placed in manual but the diff_Press signal remains noisy when compared to the EndY signals (graphs 3 & 4.)  Under WP 4040, Kyle shut down the Purge Air System in the mechanical room (that was a relief) but it had no affect on the signal noise, see second plot.
All the pressure sensors (there are four) on the pump station are noisy.  The Pump/Motor of this Pump Station is especially noisy and this may be the source.  It needs a bearing or something job. Whether the HEPI system cares about this we'll have to see.
