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.
