Figure 18 - ITV Device Control and Status web page
On this web page, the current ITV pressure or vacuum value will be displayed dynamically based on
the pressure unit selected. The page also shows ITV system status and ITV supply voltage
dynamically. This page allows the user to override PLC control, change pressure units, enable or
disable the pressure engineering unit mode, and change user gain and user sensitivity:
Pressure Unit
–
Used to display the pressure in counts or the engineering unit desired. If
Engineering Unit Mode enable this will also select the engineering unit type.
Current Pressure
–
This is the current feedback pressure from the ITV in the unit type selected
above.
Pressure Setpoint
–
Shows the current setpoint set via the PLC unless the Override PLC Control is
enabled. If the pressure setpoint value entered is legitimate, the ITV will regulate to this new
pressure or vacuum. The pressure displayed on the Current Pressure box will change to the new
regulated pressure value.
If the pressure setpoint value is out of range, the entered data and the title of “
Pressure Setpoint
”
will be displayed in red and a note in red on the right side of the data entry will be displayed to
indicate the data of the legitimate range. When the pressure setpoint value is out of range, the user
cannot submit the pressure setpoint and will get an error message
“
Parameter setup error. Please
correct the error and submit it again”
on the web page.
