The state of the valve can be:
1. Closed (Remember that the SmartTrak is not a positive shut-off device).
2. Purge--Maximum Open (recommended 120% of the calibrated full scale value, but
can be much more and can be dangerous)
3. Automatic (the normal position, where the controller responds to a setpoint signal).
WARNING: The flow rate in Purge is muchgreater than the calibrated
full scale value and as a result can be dangerous.
For normal operation of the flow controller, this screen should display:
Valve
Automatic
Normal
If this is visible, the instrument will automatically control flow as soon as a setpoint is
given to it. If this screen displays Closed or Purge, the instrument has been placed into an
override position and it will not respond to any setpoint signal. The valve state may be
changed using the “Change Valve Operation” as described on page 4-16.
Full Scale Screen
Pressing the right arrow again takes you to the Full Scale Screen. This screen displays the
current full scale value of the instrument with engineering units. It also displays the gas.
Note that this is not necessarily the factory calibrated full scale value. The screen will
display:
Full Scale
10.00
sl/m
Nitrogen
To change the full scale value, see the section below titled “Change Full Scale Screen.”
Pressing the right arrow again takes you back to the Mass Flow Screen.
