PLC Calibration

 

This menu is only used with the Nitrider Control system when the PLC is handling the gas flow readings and control.  Contact SSI at 513-772-0060 for assistance with this feature. Press the appropriate button to select that gas valve – i.e., press H2 for the H2 valve.  The selected valve will be displayed at the top of the screen. 

 

The first section is for the Setpoint Output.  All of the buttons in both sections function identically.  Press the Zero button to set the zero value.  The text above the buttons will read “Enter measured Zero value (mA) and press calibrate”.  Press the Span button to set the span value.  The text above the buttons will read “Enter measured Span value (mA) and press calibrate”.  Press the Cancel button to cancel the zero or span process.  Press the Nominal button to set nominal values for the Setpoint Output.  This will display a message box: “Set nominal zero values.  Are you sure?”  Press the Yes button to set the nominal values, or press the No button to cancel the nominal value set.  Press the Edit button to display a numeric keypad that will allow the user to edit the zero or span value.  This can range from 0.00 to 32767.00.  Press the Calibrate button to begin the calibration process.  This will display a message: “Begin Calibration.  Are you sure?”  Press the Yes button to begin the calibration process, or press the No button to cancel the calibration process. 

 

The second section is for the Flow Input.  Press the Zero button to set the zero value.  The text above the buttons will read “Enter observed Zero flow value and press calibrate”.  Press the Span button to set the span value.  The text above the buttons will read “Enter observed Span flow value and press calibrate”.  Press the Cancel button to cancel the zero or span process.  Press the Nominal button to set nominal values for the Setpoint Output.  This will display a message box: “Set nominal zero values.  Are you sure?”  Press the Yes button to set the nominal values, or press the No button to cancel the nominal value set.  Press the Edit button to display a numeric keypad that will allow the user to edit the zero or span value.  This can range from 0.00 to 32767.00.  Press the Calibrate button to begin the calibration process.  This will display a message: “Begin Calibration.  Are you sure?”  Press the Yes button to begin the calibration process, or press the No button to cancel the calibration process.
