trollers used with the Quantum HD Unity System Controller.
One controller for each major system component:
Condenser/Vessel, Engine Room, and Evaporator.

on board areas such as power, communications, and
Ethernet connectivity.

Power Up Sequence
When powering up, the following sequence of events are
indicative of a properly working main processor board:
1. The six LEDs in the lower left corner light up solid.
2. The on-board “beeper” will beep once.
3. Several different screens will be shown through the
booting up process.
4. Just before fully booting, a Screen Calibration page
appears. It is best practice to calibrated when commis-
sioning a new system. It not necessary to calibrate the
screen after this unless the screen response appears to
be off.
5. After booting, the System Overview page appears.
After the Q5 processor board has completely powered up,
the following sequence of events indicatives proper com-
munication to the analog and digital boards:
1. The Analog and Digital I/O boards TX/RX lights will
blink.
2. The power LED for each I/O board will be on and the
Active LED will be pulsing.
The first thing to check when troubleshooting the Q5 pro -
cessor board is its powering up sequence.
Troubleshooting
If the System Overview screen is not shown, check the
following items:
1. If no LEDs are lit, then check AC and DC power. See the
Power Supply section.
2. Check if the lighting of the LEDs is occurring as de-
scribed in the Power Up Sequence section.
• If the powering up sequence continues to repeat
without displaying the System Overview screen, then
there is a booting problem.
3. Check all plugged connectors for proper seating.
4. Check if an error message is displayed when booting.
• Be sure to write down or take digital pictures of any
error messages exactly as they appear, as well as the
top line on the screen where the message appears.
5. Check that the software is OK:
• Is the correct software installed?
• Did you just install new software?
6. Check the display. If the Q5 processor board is booting
but you have no display, check the following:
• Check the backlight operation. Inspect the display
very closely to see if anything is visible in the dark
screen. Using a beam-type source of good lighting,
such as a flashlight, look for any ghost-type image. If
it appears that there is something on the screen but
very dark, the problem may be with the backlight.
• Verify that both the display cable and the inverter
cable are firmly seated at both the processor and
display connection points. It may be necessary to
remove the video cable from the back of the display
and re-seat it to be sure it is connected properly.
NOTICE
Power down the controller before performing these
tasks.
NOTICE
This is a small connector and caution should be
observed so that it is not damaged due to excessive
force.
