Flow Detail

This screen is displayed by pressing the NH3 Detail button.

The operator can change the gas flow setpoint by touching the setpoint on the screen next to the words “Flow Setpoint”.  When pressing the setpoint box, a numeric keypad is displayed, showing the current value and allowing you to enter a new setpoint by simply pressing on the appropriate numeric keys. Once the correct setpoint has been entered, press the Enter key to make the change. When the Enter key is pressed, the display returns to the “NH3 detail” screen.  The other active buttons - Trim Enable and Trim Range - are used in the same way. Pressing the Trim Enable button allows the user to enable or disable trim adjustment of the gas flow.  Depending on the current Login, the screen may prompt for the Supervisor or Administrator password before the Trim mode can be changed. Pressing the Trim Range button displays an alphanumeric keypad that allows the operator to change the trim range. 

The flow detail screen has a Close Valve button that allows you to manually close the flow valve.  Pressing the Close Valve button sets the Flow setpoint to zero (0) and causes the valve to drive close for two minutes.

The NH3, N2, DA, and AUX detail screens are used in the manner discussed above.
