WHAT TO DO BEFORE CALLING THE FACTORY
When someone calls in to the factory with a suspected
Quantum™ problem, sometimes the person calling doesn't
provide enough information. This is because they most
likely are not aware of the type of information that would
be useful to factory personnel in helping to identify and
correct the problem. An example of this is the statement
that the Quantum™ 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
• Wrong Combination of Display, Cable, Inverter,
or Software
• Faulty CPU Board
Before calling the factory for assistance, review the
information on the following pages and try to discover and
resolve your Quantum™ problem. The actual cause of
most problems is usually not with the Quantum™ itself,
but with something external to the Quantum™. However,
on the rare occasion that the problem has been identified
as being the Quantum™ controller, use the following
section as a guideline for replacing it.
REPLACING THE QUANTUM™ BOARD
The Flash Card memory load is done prior to the board to
the board shipping. The customer will still need to either
have their settings manually recorded, or saved to a Flash
Crad, so that the new board can be setup the same as the
old one. It is suggested that the operator first record all
control setpoints prior to board replacement. Factory
Setup settings will also be lost. The setpoint data
sheets are useful for recording this information. A
Maintenance Flashcard may also be purchased that will
allow these setpoints to be saved electronically, and may
be downloaded at a later time. Make sure that the operator
can access Factory Setup to restore all compressor
specific settings.
The procedure to replace the main board is outlined
below:
1. Shut off control power.
2. Remove the old board from the machine and the
new board from its packing and place both on an
anti-static surface.
3. Ensure that the jumpers on the new board are set
the same as those on the old board.
4. Install the modified replacement board into the
panel.
5. If program changes are necessary through a
Flash Card download, then follow the directions
in the Factory Setup manual (S90-010 FSI) for
the procedure to reload a program Flash Card.
