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 stages for determining Purified Water. There is a sub-screen that allows you to change the Pharma Test Stage and adjust the Pct Warning value (Stage 1), Test µS/cm value (Stage 2) and the Test pH (Stage 3). (See Section 5.8 for details)

Cation Calc – When cation Calc 1 or 2 is active there is a display screen for either cation or degassed CO2 measurement. (Section 5.9)

Status Display - of Alarms Status, PID Alarms Status, Logic Status, Input Status, Output Levels, Relay States, Monitor Status, Math Values, Aux Values, Variables, Comm Status, System Status, and Calculated Values. (Section 5.10)

Event History - Event History records events with timestamp. (Section 5.11) Events recorded include setup change, power on, calibrations (no values) and alarms with detail available on alarm type and source by scrolling and selecting event name. Status warns of event history at 50% and 90% and when erasing old records.

Contrast Adjustment

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 there are currently menu items above the screen accessible by moving the cursor up.

A downward-pointing arrow indicator below the menu at the left end of the status footer appears when there are currently menu items below the screen accessible by moving the cursor down.
