Operator Interface Panel. The following is a list of
possible reasons for the Quantum™ 4 not to boot:
No power (AC or DC)
Loose or faulty cables
Faulty CPU Board
Tripped circuit breaker
Before calling the factory for assistance, review the
information on the following pages and try to discover
and resolve your Quantum™ 4 problem. The actual
cause of most problems is usually not with the
Quantum™ 4 itself, but with something external.
However, on the rare occasion that the problem has
been identified as being the controller, use the
following section as a guideline for replacing it.
REPLACING THE QUANTUM™ 4 BOARD
The Flash Card memory load is done prior to the
board shipping. The customer needs to have their
settings manually recorded, or saved to a Flash Card,
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.
A
Maintenance Flashcard may be purchased that will
allow these setpoints to be saved electronically, and
may be restored at a later time. Make sure that the
operator can access Security Level 2 to restore all
compressor specific settings.
The procedure to replace the Quantum™ 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 flash card from the old board to
the replacement board.
5.
Install the modified replacement board into
the panel.
6.
If program changes are necessary through
the USB port download, then follow the
directions in the Software Maintenance
section of this manual for the procedure to
reload a program Flash Card (see the
section entitled
Software Maintenance
).
WHAT SHOULD OCCUR WHEN APPLYING POWER
The first thing that should be checked when
troubleshooting the Quantum™ 4 is it’s powering up
sequence.
When powering up the Quantum™ 4 the following
sequence of events are indicative of a properly
working main processor board:
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.
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™ 4
has booted.
LED's D4, D5, D7 and D9 will turn on solid.
LED D11 and 12 will turn on solid. D4, D5,
D7, D9, D10 and D13 will be flashing in
random patterns. The flashing of the RX/TX
lights of the Analog and Digital boards will
also prove a successful boot.
After the Quantum™ 4 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 Analog and Digital I/O boards TX/RX
lights should be blinking.
Each I/O board should have the power LED
(next to the white connector) lighted and the
Active
LED (next to the blue Dipswitch)
should be blinking.
