Main Overview Screen

Using the operator interface shown below you can configure the Model 9120.

 

 

The Main Overview screen will be the initial screen that is displayed when the Touchscreen is first started up.  The Main Overview screen will display each loop’s: type, setpoint, current value, output mode, output, the activated/deactivated inputs and outputs, any messages, as well as the Menu button and the Chart button.  Any activated inputs or outputs will be lit up.  In the picture above, no inputs are activated, and outputs 0 and 7 are activated.  Note on Inputs and Outputs – The numbering on the display starts at 0 instead of 1, so input 2 shown above is actually input 3, and output 4 is actually output 5.  Any activated output will also be lit up on the Touchscreen unit.    The red bar will display any messages. 

 

The list of runtime messages displayed depends on the setup of the 9120 instrument.

  • H2 cell communications failure – There is a problem with the communications with the H2 cell

    • Selection n forced by digital input – Indicates that the selected probe has been forced by digital input.  Digital input 1 selects probe 1; input 2 selects probe 2.

    • User controlled – Indicates that the probe has been manually selected by the operator.

  • Both inputs over 1300 mV – Both inputs are over range.

  • Probe Deviation – The selected alarm is active.  See the alarms section for instructions on setting up the alarms.

     

The list of error conditions is:
