The Operator Interface Panel (we will call it the In-
terface Panel throughout the rest of this guide) is the
central point of the system, whereby all Remote Zone
Interface Panels are attached. It can easily be identi-
ed by the presence of a display screen and a keypad.
The Interface Panel monitors and controls all of the
Remote panels that are attached to it, through RS-
485 serial communications (to be explained later).
The Interface Panel runs the actual program that
provides the control for the entire system. Through
communications, it monitors the status of each
attached Remote Zone Interface Panel, and provides
the necessary control instructions for each Remote
Zone Interface Panel to perform. Additionally, all
setpoints are stored in the Interface Panel.
Status of the entire system may be monitored form
here, and appropriate changes made to system
operation.
THE REMOTE I/O PANEL
Each complete Evaporator system will have from one
to ten Remote I/O Panels, and each panel is capable
of controlling up to 3 Evaporator zones:
Quantum LX Evaporator
Remote PanelNumber: ___________
Notice that there is a yellow sticker on the front
of the door for each Remote I/O Panel. This sticker
will identify the Remote Panel number and the
Zones it will control. This will all be explained in
greater detail later, but it is an important fact to
note.
The Remote Panels do not have a display or keypad. Each
Remote Panel can control three independent Zones. Each
Quantum™ LX Evaporator system can manage up to 10
Remote I/O Panels, providing the ability to control as
many as 30 Evaporator zones.
SETUP DESCRIPTION
The following Setup Guide is meant to assist the installation
technician in making all necessary electrical power, control and
communications connections to a Quantum™ LX Evaporator
system. They will be provided also with the basic information
necessary to login and congure the system. It will then aid in
troubleshooting the system should problems arise. This Guide
will help to ensure:
WIRING
• Location of incoming AC source power to all
panels (Interface and Remote)
• Basic installation guidelines are followed.
• Location, polarity and grounding of
communications wiring.
• Location of all control (I/O) wiring.
• Proper powering up of all panels.
CONFIGURATION
• Logging into the system.
• Verifying communications.
• Conguring the Zones.
• Calibrating sensors.
• Setting up operating Setpoints.
OPERATION
• Setting the operating Mode.
• Verifying the data being returned to the Interface
panel from all remote panels (Zones).
• Checking and clearing of alarms.
• Zone overview
• Ammonia Conguration
IDENTIFYING AN EVAPORATOR SYSTEM
A minimum Evaporator system will include one Operator
Interface Panel and one Remote I/O Panel.
THE OPERATOR INTERFACE PANEL
Each complete Evaporator system will have a single
Operator Interface Panel, as shown below:

SYSTEM INSTALLATION
An in depth installation setup is beyond the scope of this guide,
however some basic rules can be observed:
▯ Pay particular attention to the yellow sticker on the
front of each Remote I/O Panel. It will have been lled
in at the factory, as to which panel will control which
zone. This is a close-up of the sticker:
Quantum LX Evaporator
Remote Panel Number: ___________
Zone: ___________
Zone: ___________
Zone: ___________
▯ Maintain a total distance of 2000 feet or less between
the Operator Interface Panel, and the very last Re-
mote I/O Panel on any one communications cable
run. As will be explained later, it is possible to have
two separate communications cable runs, depending
upon the total number of Remote I/O Panels. Keep
in mind that neither of these cable runs can exceed
2000 feet in length.
▯ Remote I/O Panels should be mounted in close prox-
imity to the zones that they will be controlling. In
some instances, there may be fan motor starters lo-
cated in a separate area from the zone, so it may
be more convenient to locate the Remote I/O Panels
near the starters, than the actual Evaporator unit. The
idea is to minimize the length of the control wiring, so
if there is less wiring to the zone than to the starters,
then install close to the starters or vice-versa.
▯ The system is capable of Ethernet communications,
this may be something to consider when placing In-
terface Panels, as you would want a nearby Ethernet
connection to be available.
▯ Keep all communications wiring in a separate conduit
from control wiring.
▯ When wiring for communications, it is important to
ground only one end of the communications cable.
This ground will be located in the very last Remote
Panel of each communications cable run. If the com-
munications were to be grounded at both ends, then
it would be possible for ground loops to develop,
which could impair communications between panels.
▯ Interface Panels should be located in easy access ar-
eas, and should be mounted at eye level for screen
viewing.
▯ Remote Panels are rated for both indoor and outdoor
use. Although access to the Remote Panels will be
rare after installation and setup, it is still advanta-
geous to keep them accessible for potential mainte-
nance situations (reasonable lighting, sufcient door
swing, etc.).
▯ Install all panels within a convenient distance of a
power source.
▯ Refer to the Zone Conguration Chart for additional
information.

CHECKING THE AC POWER
Interface Panel
▯ Ensure that the Control Power switch is in the
OFF position.
▯ Energize the 120 Volt circuit at its source.
▯ Using a DVM, measure the voltage at the AC
power terminal strip. Ensure that you read ap-
proximately 120 VAC between Hot and Neutral,
and Hot and Ground. There must not be voltage
between Neutral and Ground.
▯ Once the incoming voltage has been veried,
turn the Control Power switch to ON.
▯ On the enclosure door, and watch the Quantum™
LX controller (on the backside of the door). You
should notice various LED’s blinking or ashing.
▯ Watch the display on the front of the door. Af-
ter a short period of time, you should notice the
display showing a boot sequence. Various text
messages will be shown as it proceeds with the
boot-up process. When nished, a screen similar
to the following image should be visible:
▯ If the panel has reached the point of showing the
above screen, the boot process was successful.
Turn OFF the Control Power switch, and De-en-
ergize the 120 Volt circuit at its source.
▯ If the panel does not reach to the point of show-
ing the above screen, then troubleshooting will
be required. Refer to end of this guide entitled
Troubleshooting.
Remote Panel(s)
▯ Unlike the Interface Panel, the Remote panels
do not have an external power switch. Instead,
the enclosure will contain two HOA (Hand-Off
Automatic Modules). These modules allow the
technician to override control signals, by manu-
ally energizing components. An example of one
of these modules is shown here:
Red, power OFF
tab
Black, power ON
plunger
▯ Notice in the above pictorial, there is a Red pow-
er OFF tab, and a black power ON plunger. These
items are located on a circuit breaker for each of
the two HOA modules. Together, they act as the
Control Power switch.
▯ Push each of the Red power OFF tabs down. The
Black power ON plunger should pop up. If the
plunger does not pop up, then the power was
already off. Do this to both HOA modules.
▯ Energize the 120 Volt circuit at its source.
▯ Using a DVM, measure the voltage at the AC
power terminals (1, 2 and PE). Ensure that you
read approximately 120 VAC between Hot and
Neutral, and Hot and Ground. There must not be
voltage between Neutral and Ground.
▯ Once the incoming voltage has been veried,
push in the Black power ON plungers of both
HOA modules.
▯ To the right of the HOA modules are several I/O
boards. There will be at least one Digital board
(recognizable by the plug-in I/O modules), and
one Analog board. Inspect all boards for the
presence of ashing, blinking or steadily lit
LED’s. If LED’s are lit on all boards, then power
has been properly applied.
▯ If LED’s are not lit on all boards, then refer to the
section entitled Troubleshooting.

WIRING FOR COMMUNICATIONS
NOTE: Refer to the next sections entitled ZONE CON-
FIGURATION CHART and EVAPORATOR SYSTEM COM-
MUNICATIONS WIRING DIAGRAM, for additional infor-
mation about how the system is congured.
Interface Panel
Depending upon the number of Remote Panels that
have been installed, there could be up to two dif-
ferent communications cables run to the Interface
Panel. One of these cables would feed Remote I/O
Panels 1 through 5, and a second cable would feed
Panels 6 through 10. The incoming RS-485 commu-
nications cable(s) will be a two-conductor, shielded
type. Frick Controls recommends the use of Belden
#9841 or equal.
Wiring for 1 to 5 Remote Panels
For systems that have between 1 and 5 Remote
Panels, use the following wiring procedure:
▯ Open the panel door.
▯ On the inside of the enclosure door, you
will nd the Quantum™ controller, and
a communications terminal block. No-
tice that there are two wires that con-
nect from the left side of the terminal
block, to the Quantum™ (Comm. 4).
These are the internal TX / RX commu-
nications wires. You will be connect-
ing the external eld communications
wires to the other (right) side of these
terminals.
▯ Take the end of the incoming commu-
nications cable, and strip about 2 inches
of insulation from the end.
▯ Clip the shield wire back even with the
insulation, and either use heat shrink
tubing to cover the area, or electrical
tape. This will help to ensure that any
strands of the shield that may be ex-
posed don’t come into contact with any
live voltage areas of the panel.
▯ Strip the end of each of the two re-
maining conductors back about ¼ of
an inch. Generally there are only three
color combinations available depending
on the type of cable used. There will be
either a black and white/clear insulated
wire, a red and white/clear insulated
wire, or a red and black. Either way,
one of the wires should be black. Take
the black wire and insert it into the top
position of the terminal block (labeled
as –TX/RX).
▯ Take the remaining wire (white/clear or
red) and insert it into the second posi-
tion down from the top of the terminal
block (labeled as +TX/RX).
▯ It is very important that the colors of
these wires follow this same polarity
scheme throughout the daisy-chaining
process to all panels.
▯ Refer to the Zone Conguration Chart
later in this guide to verify dipswitch
settings.
Wiring for 6 to 10 Remote Panels
For systems that have Remote I/O Panels 6
through 10, use the following wiring procedure:
▯ Open the panel door.
▯ Follow the same guidelines for insu-
lation and wire stripping as described
earlier.
▯ For Q5 board installation, skip this step.
On controllers that have the Q4 board,
there is a DIN rail mounted below the
incoming power strip. On the DIN rail
is mounted a RS-232 to RS-485 com-
munications converter module (Comm.
3), and a power supply. Both of these
components have been pre-wired at
the factory. All that is left to do is con-
nect the eld connections. Refer to the
following pictorial for connections:
TX/RX+
TX/RX-
▯ For Q5 board units, skip this step. For
Q4 board units, Insert the black wire
into the top of the module in terminal
position 4, and the white/clear or red
wire into position 6, as shown above.

QUANTUM™ LX EVAPORATOR CONTROL PANEL
OPERATION
090.610-O (MAR 2016)
Page 12
▯ For Q5 units, connect the Comm-3
communications wires directly to the
appropriatly labled Comm-3 terminal
strip.
▯ This should complete the Interface
Panel communications wiring.
▯ This should complete the Interface
Panel communications wiring.
▯ Refer to the Zone Conguration Chart
later in this guide to verify dipswitch
settings.
Remote Panel(s)
Follow the same description for wire stripping as with
the Interface Panel, with the exception that the shield
wire does NOT get trimmed off.
▯ On Evaporator systems with only one Re-
mote Panel, the only communications cable
that you will have is that which comes di-
rectly from the Interface Panel.
▯ Insert the stripped end of the black wire into
the terminal marked TX/RX-, and the white/
clear or red stripped wire into the terminal
marked TX/RX+, and the shield wire into
the Ground terminal as shown (the Ground
terminals may be identied by their Green/
Yellow color).
TX/RX-
TX/RX+
Shield
▯ On Evaporator systems with more than one
Remote panel, the rst Remote panel will
have two communications cables; the rst
will be from the Interface Panel, and the sec-
ond will be going to the next remote panel.
Functionally, it does not matter which cable
is which, as long as the polarity of both is
observed. NOTE: It would be a good idea at
this time however to label each of the two
cables as to where they are going for future
maintenance / troubleshooting use (refer to
the yellow sticker on the front of each Re-
mote Panel for the panel numbers).
▯ Insert the black stripped wires from both
cables to the TX/RX-, and the white/clear or
red stripped wires into the terminal marked
TX/RX+. Both shield wires should be twisted
together, and then taped to prevent them
from touching any live surfaces. The shield
wires DO NOT get connected to any termi-
nals.
▯ Follow this procedure for all Remote Panels,
except for the very last one. This panel will
have only one communications cable (label
it also), which will be coming from the pre-
vious panel. The connections for this cable
are the same as that for a single Remote
Panel, that is, the shield wire must be at-
tached to one of the Ground terminals.
▯
NOTE: Only the last Remote Panel
should have the shield wire grounded
(terminated).

ZONE CONFIGURATION CHART
The following table is to be used to set the System congura-
tion. The following page then shows a pictorial representa-
tion of how this chart applies to a full system. The columns
indicate:
• INTERFACE COMMUNICATIONS PORT
• COMM. 4 – This is an RS-485 serial port physi-
cally located on the Q4 controller, or on the Q5
Interface (within the Operator Interface Panel).
This signal can directly feed all attached Remote
Panels (up to 2000 feet total distance). This port
provides communications to the digital and an-
alog boards within Remote Panels 1 through 5
(zones 1 through 15)
• COMM. 3 - On the Q4 controller, this is an RS-
232 serial port physically located on the Q4 con-
troller (within the Operator Interface Panel). This
signal requires conversion to RS-485 to meet
the distance requirements of the system, so a
converter module has been installed to provide
this conversion (provides up to 2000 feet total
distance). On the Q5 controller, this port is lo-
cated on the Interface board. This port provides
communications to the digital and analog boards
within Remote Panels 6 through 10 (zones 16
through 30)
• PANEL # - This number identies each Remote
Panel as a discrete device, similar to an address.
Each Panel can control up to 3 zones.
• ZONE # - This number identies each individual
zone in the system. It is this value that will ap-
pear on many of the Interface Panel screens to
describe the zone that is being viewed.
• BOARD # - This lists the available analog and
digital boards within each zone.
• DIPSWITCH # - This shows the settings of how
each dipswitch must be congured to recognize
the appropriate I/O board.

VERIFYING COMMUNICATIONS
The rst step in verifying communications is to view what I/O
boards have been detected by the Interface Panel. This infor-
mation will appear on the About screen, shown here:
Review the information that is shown in the Analog and Digital
Board areas of the screen. Compare what is shown against
what is actually installed.
NOTE: This screen does not update (refresh) automati-
cally. To see any new or different information that may
occur, you must access a different screen, then come
back to this one to see any new data.
The analog board area of the screen can list up to the ten
possible analog boards that are allowed, and they are listed
in a single column. In the digital board area, you will notice
that there are two columns. The left hand column represents
Panels 1 through 5 (and digital boards 1 – 10), and the right
hand column represents Panels 6 – 10 (and Digital boards 1 -
10). Refer to the Zone Conguration Chart and the Evaporator
System Communications Wiring Diagram for clarication.
Compare what is displayed here with what is actually installed
in your system. If a board is physically installed in a Remote
Panel, yet does not show up on this screen, then nd the Panel
that the board is located in, and visually check the RX and TX
LED’s on the board. These LEDs should be ashing. The RX
LED will be ashing much faster than the TX LED, but neither
should be off completely, as this indicates a potential wiring
problem.
Start by verifying that the boards within Remote Panel 1 are
correctly being detected. Then move on to the next panel, and
so on, for each of the two potential communications branches
(Comm. 3 and Comm. 4). If Remote Panel 1 shows correctly,
but there is a problem with Remote Panel 2, then do nothing
with the wiring up to and including Panel 1. Inspect instead
Panel 2 for proper communications polarity and connections.
A good indication that you have wires backwards (reversed)
would be that the RX LED is on solid within the suspect panel.
If wiring WAS found to be incorrect, make the correction, and
then access the Communications screen by selecting Congu-
ration from the Main Menu, then Communications.
On the Communications screen shown above, use the [Tab]
key to select Redetect IO Comms and press [Enter]. This
will cause the Quantum™ LX controller to reinitiate all com-
munications with the system. After Redetecting IO Comms,
wait about 30 seconds, then access the About screen once
again. If the wiring issue has been corrected, the questionable
I/O board should now be listed, and the RX/TX LED’s for that
board should be ashing normally.
If the boards for Remote Panel 2 are now properly detected,
then move on to Panel 3, etc.
When all installed boards have been detected, then the basic
setup is complete. You can now move on to conguring the
system operating parameters.

The Alpha screen shows a graphic representation of the
numerical keypad. The symbols that appear above each
key on this screen are the possible combinations of sym-
bols that are associated with the digital portion of the key.
As an example, suppose that you wanted to modify the
text line in the screen example shown. You want to
change the line from reading Auxiliary Analog 1, to Zone
1. The rst thing you would do, is to use the [Backspace]
key on the keypad to position the cursor (blinking vertical
line), to the far left side of the text. Notice as the cursor
backspaces, it erases the current line of text.
Press the number [3] key (notice that the capital Z is one
of the symbols in the line right above the [3] key). A capi-
tal Y will appear in the Current Character box. Continue to
press the [3] until the capital Z appears there. Now press
the [Up Arrow] key, and notice that the Z has been placed
on the text line in the rst position.
Next press the [6] key on the keypad, and continue press-
ing it until the small o appears in the Current Character
box. Press the [Up Arrow] key to place the o on to the
text line. Continue entering text until you are satised
with the changes that you have made, press the [Enter]
key to accept them, and you will be returned to the pre-
vious screen. Once all zones names have been entered,
press the [Submit] key.
NOTE: If many elds need to be renamed, the user
can plug a computer keyboard into the following
locations:
• For the Q4 controller - Use PS2 style plug,
and use the socket labeled PL7.
• For the Q5 controller - Use a USB compat-
ible keyboard, and plug it into one of the
two available USB connections.
ZONE CONFIGURATION
Zone Conguration is the process of setting the operating pa-
rameters of each of the installed zones.
• Global Zone Conguration – Use this screen to enable
or disable each independent zone. NOTE: If a zone is
installed, it MUST be enabled before it can be setup
and accessed. The screen also allows you to custom
name each zone.
• Current Zone Conguration –Once the Global Zone
Conguration has been setup, use this screen to set-
up the parameters for each of the individual zones (1
-30).
Global Zone Conguration
Access this screen from the Main Menu. Select Congura-
tion, then Global Zone Conguration. The following screen
will appear:
Each Evaporator zone that is in use should be set to En-
abled. The Global Zone conguration screen also provides
the ability to supply a unique name for each zone. After
moving the cursor to one of the Name elds, press the Up
Arrow key to access an alpha/numeric data entry screen,
as shown here:

Current Zone Conguration
Access this screen from the Main Menu. Select Conguration,
then Current Zone Conguration. The following screen will
appear:
Notice in the upper right hand corner of this screen is a set-
point box that contains a value. You may change the value in
this box to the number of the zone that you wish to congure.
You must then press the [Submit] button for the screen to dis-
play that zone. In the above example, the number 1 is shown
on the box. Notice that right below the setpoint box, the words
ZONE #1 is displayed, so Zone 1 is the zone parameters that
are being shown.
Many other screens also show the Zone selection box in the
upper right corner. Any screen that displays this box presents
data that pertains exclusively to the selected zone. The selec-
tions on the Current Zone Conguration page must be made
for each Evaporator zone that has been enabled on the Global
Zone Conguration page.
The Current Zone Conguration page permits the user to en-
able any four control functions:
• Cooling
• Defrost
• Dehumidication
• Heating
The Options section allows the user to congure various me-
chanical aspects of the system, which include the type and
operation of valves as well as the fan type.
CALIBRATING SENSORS
Each temperature or humidity sensor in the Evaporator should
be calibrated before the system is put into operation.
Access this screen from the Main Menu. Select Calibration,
then Analog Inputs:
The process used for establishing calibration values is rela-
tively simple. It will however require a container of ice water
or an infrared digital temperature probe.
First, establish the temperature for a specic zone’s tempera-
ture sensor. If a digital infrared measurement device is used,
simply enter the calibrated temperature into the Current Value
box and press [Submit]. The system will automatically cal-
culate the correct offset value to use. If an ice bath is used,
simply allow the temperature of the sensor to stabilize, and
then enter 32 into the Current Value box and press [Submit].
This process should be repeated for each sensor in the system.
ESTABLISHING SETPOINTS
Cooling Setpoints
Access this screen from the Main Menu. Select Set-
points, then Cooling, and nally Mode (1-4):

Zone Active / Off – This drop down menu must be
set to Active for the zone to be able to run.
Mode Control – Set this based upon whether you
would prefer Manual, Mode Schedule or Digital Input
operation. Allows the user to manually set the active
mode:
• Manual - Allows the zone to follow which-
ever Mode (1-4) setpoints have been setup,
based upon the Active Mode.
• Mode Schedule – The zone will follow the
Mode Schedule.
Active Mode – If Mode Control is set to Manual, the
user can set the active Evaporator mode.
A Defrost can be initiated at anytime be pressing the
[Start Defrost] button.
THE HOME SCREEN
This screen will appear each time the Interface Panel has
been powered up (default). It can also be accessed from
the main menu by selecting Home.
Many of the operating characteristics for each zone can
be viewed from here. The upper left hand corner of the
screen tells you which zone is currently being viewed, and
the zone setpoint box allows you to enter the number of
any other enabled zone that you may wish to view.
The square grey box in the lower left hand corner will
contain a red blinking dot if any zone being viewed has an
active alarm condition, or a yellow blinking dot if any zone
has an active warning..
This screen will display basic alarm information for the se-
lected zone, as well as the current temperature and zone
setpoint. At the bottom of this screen, basic status infor-
mation is provided about valves and the fan. The Defrost
box provides information when a defrost is underway.
The four Cooling Mode screens allow each zone to
operate with four separate groups of setpoints. This
screen shows the setpoints available for congura-
tion based upon the selecting mode on the Current
Zone Conguration page. Most importantly, the Liq-
uid On and Off temperatures should be set, as well as
the Fan On and Off temperatures. It is also recom-
mended to set the Alarm High and Low temperatures
for each Mode.
Defrost Setpoints
Access this screen from the Main Menu. Select Set-
points, then Defrost, and nally Defrost Setpoints:
The Defrost Setpoints screen permits the user to
specify the duration of each defrost step. Addition-
ally, the Defrost Initiation should be set for each zone.
During the conguration process, it is possible to
start a defrost via the Mode Setup screen (see next
section). The Next Stage button on the Defrost Set-
points screen can then be used to advance through
the defrost in order to validate valve operation.
THE MODE SCREEN
Access this screen from the Main Menu. Select Modes:
This screen is used to set each of the individual zones as
to which Mode (1-4) they will perform. As described ear-
lier, set the Zone number to the zone you which to setup.
