5.4 Displays Overview
Viewing the Displays
To view display screens, push the
Display
key. Pushing the Display key repeatedly scrolls through
screens which show the current status of pH/ORP, Conductivity, or Dissolved Oxygen
Concentration. There are displays for PID, Auto Cycle, and Pharma. It also lets you view a Status
Display and an Event History Display.
Displays Shown
One Input - When only one input board is installed, the online screen displays one PV and its
units in a larger font size (Section 5.5).
Two Inputs - When two input boards are installed, the online screen displays two PVs and its
units in a smaller font size. Press
to see single PV screens (Section 5.5).
PID - When PID 1 or 2 is active (Section 5.6 ), there is a display screen for each. There is a sub-
screen that allows editing of the Setpoint value, Setpoint Source, Control Mode, and Output
value. You can also enable or disable Accutune and Tune set.
Auto Cycle – When Auto Cycle 1 or 2 is active (Section 5.7), there is a display screen for each.
There is a sub-screen that allows you to start or stop the Cycle.
Pharma – Enabled in Conductivity inputs. Each Pharma screen monitors standard procedure

When viewing a PV or Control display, you can adjust the contrast by pressing the or key.
Bargraphs Overview
Output Bargraphs will represent up to three current output values. On the display, the Bargraphs
are the output in Engineering Units. The corner annunciators are the physical relay states (light –
de-energized, dark – energized). The third output and the 3 and 4 relays are shown only when the
source other than NONE is selected.
Menu Indicators
An upward-pointing arrow indicator above the menu at the left end of the header appears when
