General Information
Introduction To The Quantum™HD Unity
System Controller
The Quantum HD Unity System Controller consists of two
major components. The main system control panel houses
the controllers for condenser, vessel, engine room, and
evaporator control. It also houses the digital and analog
I/O for the condenser, vessel, and engine room control.
The digital and analog I/O for the evaporator control is
housed in multiple remote I/O panels that control up to 3
zones each. Up to 10 of the remote I/O panels (30 zones)
can be controlled by one Unity System Controller.
The Quantum HD Unity System Controller is designed with
best refrigeration control practices in mind for the control
of Condensers, Vessels, Evaporators and Engine Room
items such as ventilation and refrigerant detection. There
are many combinations of how the controller can be con-
gured as a result of the numerous options and features.
This manual provides information on the most common/
standard congurations.
Components
• Power supplies - Provide the necessary operating volt-
ages for proper operation of all control Components.
• Ethernet switch - Connects the various controllers to a
network.
• Q6 Processor board - The Q6 processor board is the
principal controller for the Quantum HD Unity System
Controller. There is a Q6 processor board for each of
the following controls:
–Condenser/Vessel
–Evaporator
–Engine Room
• The Q6 processor board runs software that communi-
cates with the analog and digital boards. From the status
of the data pulled from these boards along with the con-
troller conguration, the processor operates the system
by communicating commands to the analog and digital
boards. If operation moves outside of what is deemed
good operation the processor takes appropriate action.
• Digital input/output boards - The digital boards for
condenser, vessel, and engine room control are mount-
ed in the main Unity System Control enclosure. The
digital boards for the evaporator control are mounted
in smaller enclosures that can be mounted where it
makes the installation easier or better ts the mainte-
nance model for the facility.
• Digital on/off signals are sent and received by these
boards. The output modules are used to energize and
de-energize system components as commanded by
the Q6 processor board. The input modules sense the
status of the system components and communicates
that status to the Q6 processor board.
• Additional information on the digital I/O boards is found
in the Digital Board section for each control section
(condenser, vessel, evaporator, and engine room) of
this manual.
• The number of digital inputs and outputs varies from
board to board and from control to control based on
the operation.
• Analog Input / Output Boards - The analog boards
for condenser, vessel, and engine room control are
mounted in the main Unity System Control enclosure.
The analog boards for the evaporator control are
mounted in smaller enclosures that can be mounted
where it makes the installation easier, or better ts the
maintenance model for the facility.
• The analog inputs read pressures, temperatures, levels,
and other analog devices and communicates those
values back to the processor. The processor evaluates
these values to properly control the system.
• The analog outputs are controlled by the processor in
order to maintain the system in proper operating order
based on the status of the analog and digital inputs.
Each analog board has 24 analog input channels and 8
analog output channels.
NOTICE
The components within the control panel can be
inadvertently damaged by static electricity or mis-
handling. Only qualied technicians should directly
handle these components.
Basic troubleshooting
Most problems encountered with the microprocessor and
control circuits are the result of a wiring fault, a blown
fuse, faulty I/O module, or failure of a peripheral control
such as a solenoid coil or a pressure transducer. If a fault
develops in the computer, the probability is that all func-
tions will cease and the display screen will go blank. The
control system consists of an AC (high voltage) side, which
can be either 120 V, or 230 V, and a DC (low voltage) side.
The AC side actuates solenoids, relays, alarms, and other
electromechanical functions. The DC side operates the
computer and its various sensors.
CAUTION
DO NOT attempt to make corrections to the power
supply without shutting off the power to the control
panel. Accidental shorts can irreparably damage the
processor boards or the display screen.
CAUTION
DO NOT HANDLE the panel boards when their cables
are disconnected without rst attaching a properly
grounded wrist ground strap to prevent static electri-
cal discharge from your body.
DANGER
When working within the panel, inadvertent contact
on the AC high voltage side, which can be either
nominal 120 VAC or nominal 230 VAC, CAN CAUSE
INJURY OR DEATH.

MAINTENANCE
090.670-M (APR 2020)
Page 7
To troubleshoot the low-voltage side of the control cir-
cuits, it is necessary to have the following tools:
• Accurate digital multimeter, capable of reading to DC/
AC, mA to the hundreds place
• Small wire stripper
• Small screwdriver, with insulated shaft
• Small snip nose pliers
• Wrist Grounding strap
• Static free grounded work surface
NOTICE
Proper panel voltage refers to the AC voltage that
has been supplied to the panel, which could be either
nominal 120 VAC or nominal 230 VAC.
What to do before calling the factory
Many times when a suspected controller problem is called
in to the factory, not enough information is provided for
the service personnel to assist in solving the problem. This
is because the caller most likely is not aware of the type of
information that would be useful to factory personnel.
System Controller Drawings
Check the Product Drawings tab at
www.frickcontrols.com for the latest drawings.
An example of this is the statement that the Quantum™
HD Unity is not booting (the main processor board is not
starting). However, this description may only mean that
there is nothing on the display. A blank screen could be
the result of many different problems. The following is a
list of possible reasons for no display:
• No power
• Loose or faulty display cable or inverter cable
• Bad display
• Faulty processor board
Before calling the factory for assistance, review the in-
formation on the following pages and try to discover and
resolve the problem. The actual cause of most problems
is usually not with the Q6 processor board itself, but with
something external. However, on the rare occasion that
the problem has been identied as being the Q6 processor
board, use the information in Section 2 as a guideline for
replacing it.

Q5 Processor Board
Preface
The Q5 processor board is the latest in a series of indus-
trial controllers used in FRICK®by Johnson Controls control
products since 1997. There can be up to three of these con-
trollers used with the Quantum HD Unity System Controller.
One controller for each major system component:
Condenser/Vessel, Engine Room, and Evaporator.
Figure 3: Q5 processor board
Features
The Q5 processor board includes the following features:
• 6 total USB ports (2 are dedicated, 4 are available)
• 10/100/1000 Mbps Ethernet Connection
• 2 RS-422 ports
• 2 RS-485 ports
• External Video monitor connection
• LED indicators to verify proper operation of various
on board areas such as power, communications, and
Ethernet connectivity.
• 2 GB RAM memory
• Battery to maintain date and time
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 rst 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 ashlight, 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 rmly 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.

Battery Function
The processor board uses a battery to maintain cor-
rect date and time for the purpose of stamping warnings
and shutdowns as they occur. If the date and time are
not being maintained properly, this may indicate that the
battery is not functioning, and needs replacement. Order
the battery through Baltimore Parts (P/N 333Q0001786)
or purchase at most electronic shops (manufacturers P/N
CR-2032).
Battery Replacement
The battery is fully accessible but is surrounded by sensi-
tive electronic components, so take care when changing.
Replace the battery using the following procedure:
1. Power off the panel.
2. Put on an anti-static wrist band and connect it to the
ground wire in the lower left corner of the processor
board.
3. Locate the battery socket.
Figure 4: Battery
4. There are two small retainer clips along the right side
edge of the battery. Carefully insert a small screwdriver
into the slot along the left side edge of the battery.
Carefully apply a small amount of pressure to right and
then up to remove the battery.
5. Place the new battery into the socket in the same ori-
entation as the old battery, the side with writing facing
out, so that it is beneath the retainer clips on the right.
6. Carefully apply pressure down and to the right to seat
the new battery.
7. Power up the panel and wait until the Quantum HD ap-
plication has loaded.
8. After the Q5 processor board has rebooted, navigate to
Sys Cong > Panel to set the correct date and time.
Q5 Interface Board
FRICK has developed an interface board which allows the
user to interface exterior connections to the Q5 processor
board:

Power Supplies
Description
Three power supplies are used in the Quantum HD Unity
System Controller:
+5 VDC (25W/5A) 5.1 VDC to 5.2 VDC
+12 VDC (72W/6A) 12.2 VDC to 12.5 VDC
+24 VDC (72W/3A) 24.2 VDC to 24.6 VDC
The 5 VDC is used primarily for the digital boards.
The 12 VDC is used primarily for the processor and interface
boards. The display is powered from the processor board.
The 24 VDC is primarily used for the analog boards, ether-
net switch, and other ancillary items.
It may be necessary to add additional power supplies for
system components so as to not overload these power
supplies.

Measuring voltages CAUTION
Measuring and adjusting the power supply volt-
age requires the control power switch to be ener-
gized. Extreme care must be observed when taking
any readings, as 120 VAC or 230 VAC (depending on
incoming system voltage) will be present next to the
DC voltage connector.
Adjusting the supply requires the use of a small Phillips
screwdriver inserted into the supply to access an adjusting
potentiometer. Note that the tip and shaft of the screw-
driver must be non-metallic.
WARNING
It is possible for the screwdriver, and the person
making the adjustment, to come into contact with
potentially lethal voltages. Proper Personal Protective
Equipment (PPE) measures need to be observed.
All circuit boards within the Quantum HD Unity System
Controller require accurately adjusted DC voltages in order
to function properly. Periodically measure and adjust the
DC power system for optimum system operation. Over
time, it is possible for temperature, humidity, vibration,
and component age, to degrade the accuracy of these
voltages. When any of the DC voltages begin to stray from
their optimum range, abnormalities or problems may arise.
To perform measurements and adjustments on the power
supply voltage, use a reliable, calibrated digital volt meter
(DVM). Check the voltage only after the controller is fully
booted and the System Overview page is viewable. If the
screen never appears however, possibly due to a voltage
problem, you need to proceed regardless of what is or is
not displayed.
In order to properly measure the DC power system, rst
check at the DC power supply.
Adjustment
Ensure that the meter is set to the proper range (DC,
0 V to 50 V or equivalent), as well as observing proper
wire polarity. The power supply image shown below ap-
plies to all three power supplies. The adjustment access
hole for each supply is located on the lower left of the
front of the supplies. If an adjustment is required, use a
thin Phillips screwdriver and insert the tip into the access
hole for the appropriate voltage potentiometer. See the
power supply image for adjustment location.
NOTICE
Extreme care must be used when adjusting the po-
tentiometer. Adjustment should only be performed by
qualied personnel. Use a non-conductive device.
The 24 VDC power supply is the same as the 12 VDC
power supply with regard to terminal location, test point,
and adjustment potentiometer

Power supply replacement
If the power supply is found to be bad, or not capable of
acceptable adjustment, the failing supply needs replace-
ment. See the Replacement Parts section for the appropri-
ate part number.

Preface
Frick Controls has released the latest version of the Quan-
tum HD Unity Control System. The redesigned micro-
processor, referred to as the Q6 Processor Board, is the
brains of the system. The Q6 Processor Board combines
the functions of the Q5 Processor Board and the Interface
Board into a single board.
Features
The Q6 Processor Board includes the following features:
• 4 USB ports
• 10/100/1000 Mbps Ethernet port
• 1 RS-422 port
• 3 RS-485 ports (2 dedicated, 1 available)
• External HDMI video monitor port
• LED indicators to verify proper operation of onboard
systems such as power, serial communication, and
Ethernet.
• 4 GB of RAM memory
• Battery to maintain date and time
External serial communications previously made possible
through the Frick Controls Interface Board are now directly
supported by the Q6 processor board.
Power up Sequence
When powering up, the following sequence of events are
indicative of a functioning Q6 Processor Board:
• All LEDs turn on solid, excluding the CFast, SATA, and
SATA Host LEDs
• Active, User 1, User 2, and SD Card LEDs turn off
• Rx and Tx LEDs for COM1-COM4 turn off
• CFast and SATA Host LEDs will blink rapidly to indicate
activity
• The display shows a black screen with a graphic
• The display changes to a white screen with the text
“Open Embedded” and a loading bar
• The display changes to a blue screen with the text
“Quantum HD Loading”
• The Active LED (blue) begins to blink slowly
• Ethernet port LEDs turn on to indicate network link
speed (if used)
• The display now shows the Operating Status (Home)
screen
After the Q6 Processor Board has completely powered up,
the following sequence of events is indicative of proper
communication to the analog and digital boards:
• Rx and Tx LEDs for COM4 on the Q6 Processor Board
will blink rapidly to indicate activity
• Analog and Digital I/O board’s Rx and Tx lights will blink
rapidly to indicate activity
• The Power LED on each I/O board will be on solid, and
the Active LED will blink slowly
This power-up sequence is the rst thing that needs
checked when troubleshooting the Q6 Processor Board.
Troubleshooting
If the Operating Status screen is not shown, check the fol-
lowing items:
1. If no LEDs are turned on, check AC and DC power (re-
fer to the Power Supply section of this manual)
2. Check if the lighting of LEDs is occurring as described
in the What Occurs When Applying Power section
• If the power-up sequence continues to repeat with-
out displaying the Operating Status (Home) screen,
there is a booting problem
3. Check all plugged connectors for proper seating
4. Check for any error messages that are displayed while
booting
• Write down any error messages exactly as they ap-
pear (taking a picture with a mobile device is useful
as well)
5. Check that the software is OK:
• Is the correct software installed?
• Was new software just installed?
6. Check the display (if the Q6 Processor Board appears
to be booting properly and the display is not illumi-
nated)
• If only a portion of the display looks darkened, one
of the backlights has failed
• If the entire display is dark, use a beam-type light
source such as a ashlight to look for a ghost-type
image (something is displayed on the screen but it is
very dark)
• If a ghost-type image is present, the display back-
light cable is improperly seated, the display backlight
has failed, or the Q6 Processor Board has failed
• Verify that both the LVDS display cable and the
backlight cable are rmly seated (it may be neces-
sary to remove the LVDS display cable from the back
of the display and re-seat it to ensure it is connected
properly)
WARNING
This is a small connector. Observe caution when
unplugging and re-plugging this cable to avoid any
damage due to excessive force.
Battery Function
The processor board uses a battery to maintain the cor-
rect date and time for the purpose of stamping warnings
and shutdowns as they occur. If the date and time are
not being maintained properly, this may indicate that the
battery is not functioning, and needs replacement. Order
the battery through Baltimore Parts (P/N 333Q0001786)
or purchase at most electronic shops (manufacturers P/N
CR-2032).
