A summary screen is displayed while the WCU controller is on. This display shows
a bar graph of the copper concentration relative to the set point, a digital display of
the copper concentration, and the current operating conditions.
Towards the center of the bar graph is an (S), which represents the set point. For
each 1% rise above the set point a vertical line appears to the right of the (S). For
each 1% drop below the set point a vertical bar appears to the left of the (S). There
are small breaks in the bars at each 5%. If high or low alarm limits are reached, then
either an (H) or (L) will appear.
The operating conditions which may be displayed on the bottom line of the display
are: Control Delay 30* (number counts down), Sensor Error, Light Bulb Out, No
Sample, Plate Out, Manual Output* Interlock, Output Disabled*, Pump Overrun,
High/Low Alarm, Turnover Limit, Calibration Time, Outputs On* and Normal*
*These messages do not activate the diagnostic alarm relay.
