FRICK®QUANTUM™ LX COMPRESSOR CONTROL PANEL
OPERATION - SERVICE
WEB BROWSER
The web browser interface can be viewed from any
desktop or laptop computer, which has access to the
network that the compressor panel is attached to. To
change screens, setpoints, etc., you simply use a mouse
and the keyboard to view and change data.
All screens that are shown will have a several buttons on
the right hand side of the screen. Most screens will have
four buttons, and one setpoint box. The three buttons are:
[Menu] – Clicking on this button will cause the main
menu to appear on the left side of the screen. Clicking
a second time will cause the menu to disappear.
[Start Refresh] [Stop Refresh] – This button(s) appears
immediately below the [Menu] button. This is actually a
toggle button, as it changes function from Start Refresh
to Stop Refresh each time it is clicked on. When the
button shows as Start Refresh, a setpoint box will
appear below it, with a time value displayed. The time
value determines how often the display screen will
refresh, or update its values. This time value is
defaulted to 5 seconds, which means that the display
will update all values shown every 5 seconds.
Depending on the network connection speed, this
updating may interfere with your ability to change data
setpoints, because the screen will refresh while you are
entering the data. To solve this, simply increase the
refresh time. The other alternative is to toggle the
Refresh Button. By pressing [Stop Refresh],screen
refreshing will terminate, and the time setpoint box will
reappear. In this state, the particular screen that you
are viewing will never update the displayed values.
Changing to another screen will show the most recent
values on the new screen, and then will not update
again. So in the Stop Refresh state, screens will only be
updated when new screens are accessed. This feature
should not be used when monitoring for data. Try to
find an acceptable refresh time for the Start Refresh
state.
[Submit] – After having made changes to any
information, the [Submit] button must be pressed for
the controller to accept the new changes. This button
performs the same function as the physical [Submit]
button on the panel keypad.
NOTE: One screen that DOES NOT show any of these
buttons is:
Software Maintenance
– To leave this screen,
click on the [Exit] button. Note: Using the [Exit]
button takes several seconds, and it will force the
password level back to zero.
[Help] – This button will appear on all screens with
the exception of the
Documentation
screen. When
pressed, the appropriate page(s) of the Operators
Manual will be shown to help describe the functions
of the applicable screen.
There are numerous screens that have additional buttons
to those mentioned here. These additional buttons are
self-intuitive, and as such, are not discussed here.
CHANGING SETPOINTS
The setpoints define the operation and limits of the
compressor. These setpoints can be changed by operators
in the field and are stored on the compact Flash card.
NOTE: Setpoints are not lost after power is interrupted.
However, we suggest that a list of Setpoints be recorded
and stored safely to facilitate reentry, in case there is a
need to return to the original settings.
1. The data entry fields are identified by a black box
with a white interior. The data is shown in black
text. When on a screen that has adjustable
setpoints, tab to the setpoint box that you wish to
modify (or select it on a web browser). Once the
data field has been selected, the background turns
blue, and the text turns white.
2. The current value of that setpoint is shown. Use
the keypad to enter the new value. Typing a new
value will completely erase the old value.
3. Press the keypad [ENTER] key to input the new
data in the data entry field and to move to the
next data entry field.
4. Once all entries/changes have been made, pressing
the [SUBMIT] button will save the setpoint changes
to memory.
5. If the value is out of bounds, an error message
box displays the proper range of values. Press
the [OK] button to acknowledge the error
message. Re-enter a correct value.
