FRICK QUANTUM™ CONDENSER/VESSEL CONTROL PANEL S90-555 M
MAINTENANCE Page 5
WHAT TO DO BEFORE CALLING THE FACTORY
The “Home” screen is shown.
When someone calls in to the factory with a Quantum™
related problem, many times there isn't enough
information provided. An example of this is the statement
that the Panel is not “booting” (the main processor board
is not starting). Unfortunately, this description is usually
vague and only means that there is nothing on the display.
A blank screen could be the result of many different
problems. Following is a list of possible reasons for no
display:
No power
Loose or Faulty Display Cable or Inverter Cable
Bad Display
Bad Backlight Inverter
Bad Backlight Fluorescent Tube
Faulty CPU Board
Wrong Combination of Display, Cable, Inverter,
or Software
Before calling the factory for assistance, review the
following information and try to discover what the problem
is, and resolve it.
WHAT SHOULD OCCUR WHEN POWERING UP
THE PANEL
The first thing that should be checked when
troubleshooting the Quantum™ is it’s powering up
sequence.
When powering up the Quantum™ the following sequence
of events are indicative of a properly working main
processor board:
Quantum™ 3
The LED’s for +5V, +12V, and –12V will turn
on solid. (Lower left corner of Main PCB)
LED KB will begin to blink. (Left side of Main
PCB)
Several initialization screens will appear
(these will look very similar to the way the
screen of a desktop computer appears when
it is booting.
The last of the initialization screens is the
“System Configuration” screen.
The screen will go blank for several seconds.
The “Home” screen is shown.
After the Quantum™ has properly powered up,
the following sequence of events is indicative of
proper communication to the GCU board:
The TX/RX LED’s near the white connector
will begin to blink.
The GCU board TX/RX lights should be
blinking.
Each GCU board should have the power
LED (next to the white connector) lighted
and the “Status” LED (next to the blue DIP
switch) should be blinking.
Quantum™ 4
Green PWR (Power) LED will turn on solid
(upper right corner of main PCB).
Red FLASH LED will begin to intermittently
during the Boot process. It will then go out
once the “Home” screen appears.
LED D8 (on the smaller board) will start to
blink at the rate of about once per second. It
will continue to blink after the Quantum™
has booted.
Once the screen displays “Loading…”, LED's
D4 , D5, D7 and D8 will be on solid.
The “Home” screen will appear.
After the Quantum™ has properly powered up,
the following sequence of events is indicative of
proper communication to the analog and digital
boards:
The TX/RX LED’s near the white connector
will begin to blink.
The GCU board TX/RX lights should be
blinking.
Each GCU board should have the power
LED (next to the white connector) lighted
and the “Status” LED (next to the blue DIP
switch) should be blinking.
WHAT IF THE “HOME” SCREEN IS NOT SHOWN
If the “Home” screen is not shown, check the following
items:
Quantum™ 3
1. If no LED’s are lighted, then check power AC
and DC.
2. Check if the lighting of the LED’s is occurring
as described in the “What Should Occur
When Powering Up The Panel” section.
If the powering up sequence continues
to repeat without displaying the “Home”
screen, then there is a booting problem.
3. Check if an error message is displayed when
booting.
Be sure to write down any error
messages that appear.
4. Check that the software is OK:
Is the correct software installed?
Did you just install new software?
If you need to clear the numerical
setpoint and calibration areas of
memory for any reason, clear the
memory as described in the S90-555
FSI publication. NOTE: This
information will be replaced by
factory default values, so any
setpoint and calibration data values
that need to be customized must be
reentered.
