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 Condenser/
Vessel system. They will be provided also with the basic in-
formation necessary to login and confi 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 communica-
tions wiring.
• Location of all control (I/O) wiring.
• Proper powering up of all panels.
CONFIGURATION
• Verifying communications.
• Calibrating sensors.
• Setting up operating Setpoints.
OPERATION
• Verifying the data being returned to the Inter-
face panel from all remote panels.
• Checking and clearing of alarms.
• Ammonia Confi guration
IDENTIFYING A CONDENSER/VESSEL SYSTEM
A system will include one Operator Interface Panel and
one Condenser I/O Panel and/or possibly a Vessel I/O
Panel.
THE OPERATOR INTERFACE PANEL
Each system will have an Operator Interface Panel, as
shown below:
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 any I/O panels
are attached. It can easily be identifi ed by the pres-
ence of a display screen and a keypad. The Interface
Panel monitors and controls all of the I/O panels that
are attached to it, through RS-485 serial communica-
tions (to be explained later).
The Interface Panel runs the actual program that
provides the control for the system. Through com-
munications, it monitors the status of each attached
I/O panel, and provides the necessary control instruc-
tions for each panel to perform. Additionally, all set-
points are stored in the Interface Panel.
Status of the system may be monitored form here,
and appropriate changes made to system operation.
THE CONDENSER I/O PANEL
Each system may have one Condenser panel:
The panel does not have a display or keypad.
THE VESSEL I/O PANEL
Each system may have one Vessel panel:
The panel does not have a display or keypad. A Ves-
sel panel can control up to three separate vessels.

CONDENSER/VESSEL SYSTEM CONFIGURATIONS
As stated before, each complete Condenser/Vessel sys-
tem will consist of one Interface Panel, and may have a
Condenser panel and/or a Vessel panel (a Vessel Panel can
control up to three vessels).
See the example below of a system:

operates independently of one another yet they may all be
monitored and controlled through a common computer.
Such a system would include the Quantum™ LX Con-
denser/Vessel Interface Panel, an Ethernet Hub or Switch,
Condenser/Vessel panels and a computer running a Web
Browser. A simplifi ed example of such a system (with
three Condenser/Vessel systems) is shown here:

SYSTEM INSTALLATION
An in depth installation setup is beyond the scope of this
guide, however some basic rules can be observed:
• Maintain a total distance of 2000 feet or less be-
tween the Operator Interface Panel, and the very
last Remote I/O Panel on any one communica-
tions 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.
• The system is capable of Ethernet communica-
tions, this may be something to consider when
placing Interface 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 communications were to be grounded at
both ends, then it would be possible for ground
loops to develop, which could impair communi-
cations between panels.
• Interface Panels should be located in easy access
areas, and should be mounted at eye level for
screen viewing.
• I/O 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 ad-
vantageous to keep them accessible for potential
maintenance situations (reasonable lighting, suf-
fi cient door swing, etc.).
• Install all panels within a convenient distance of
a power source.
WIRING FOR AC POWER
Interface Panel
The incoming AC power will consist of three 14 AWG
wires (hot, neutral and ground).
• Unlatch the two ¼ turn cover latches to the
Interface panel, and open the door.
• Inside the enclosure, you will fi nd a power
supply and a terminal strip, as shown here:
• Connect the three incoming AC wires to the
terminal screws as shown previously.
• Proceed to the section entitled Checking the
AC Power.
Condenser/Vessel Panel
As with the Interface panel, the incoming AC power
will consist of three 14 AWG wires (hot, neutral and
ground).
• Unlatch the two ¼ turn cover latches to the
Interface panel, and open the door.
• Inside the enclosure, you will fi nd a long DIN
rail at the left side of the panel. At the top
of the DIN rail is a terminal strip (if the unit
is equipped with an optional panel heat-
er, there will also be a circuit breaker), as
shown here:
• Connect the three incoming AC wires to the
terminal screws shown above.
• Notice that there are multiple number 2 ter-
minals, connection may be made to any of
them.
• Proceed to the section entitled Checking the
AC Power.
QUANTUM™ LX CONDENSER/VESSEL CONTROL PANEL
OPERATION 090.560-O (APRIL 13)
Page 11
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 verifi 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 fl 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 fi 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.
Condenser/Vessel Panel
• Unlike the Interface Panel, the Condenser/Vessel
panel(s) 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 manually energizing components. An example
of one of these modules is shown here:
• 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 verifi 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 fl 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 section entitled CONDENSER/VESSEL
SYSTEM COMMUNICATIONS WIRING DIAGRAM, for addi-
tional information about how the system is confi gured.
Interface Panel
Depending upon the confi guration of the system,
there may be a Condenser panel, and/or a Vessel
panel. A common communications cable needs to be
run from the Quantum™ LX panel to each of these.
Refer to the section entitled Condenser/Vessel Sys-
tem Communications Wiring Diagram. The incoming
RS-485 communications cable to the interface panel
will be a two-conductor, shielded type. Frick Controls
recommends the use of Belden #9841 or equal.
Wiring the Quantum™ LX Panel
Use the following wiring procedure:
• Open the Quantum™ LX panel door.
• On the inside of the enclosure door, you will
fi nd the Q4/Q5 controller, and a three po-
sition terminal block. Notice that there are
two wires that connect from the left side of
the terminal block, to the Q4/Q5 at Comm.
4. These are the internal TX / RX commu-
nications wires. You will be connecting the
external fi eld communications wires to the
other (right) side of these terminals.
• Take the end of the incoming communica-
tions cable, and strip about 2 inches of insu-
lation from the end.
• Clip the shield wire back even with the insu-
lation, 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 exposed don’t come into con-
tact with any live voltage areas of the panel.
• Strip the end of each of the two remaining
conductors back about ¼ of an inch. Gener-
ally 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 po-
sition of the terminal block (labeled as –TX/
RX).
• Take the remaining wire (white/clear or red)
and insert it into the second position 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 CONDENSER/VESSEL SYSTEM
COMMUNICATIONS WIRING DIAGRAM in
this guide to verify dipswitch settings.

VERIFYING COMMUNICATIONS
The fi rst step in verifying communications is to view what
I/O boards have been detected by the Quantum™ LX In-
terface Panel. This information 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) auto-
matically. 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 two
possible analog boards that are allowed (one for Con-
denser and one for Vessel). In the digital board area, Up
to four total boards may be listed:
• A Condenser panel will have one standard digital
board, and can have one optional digital board.
• A Vessel panel will have one standard digital
board, and can have one optional digital board.
Compare what is displayed here with what is actually in-
stalled in your system. If a board is physically installed in
a panel, yet does not show up on this screen, then fi 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 fl ashing. The RX LED will be fl 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 the fi rst panel
in the communications line are correctly being detected.
Then move on to the next panel. If the fi rst panel in the
communications daisy chain shows correctly, but there is
a problem with the second panel, then do nothing with
the wiring up to and including the fi rst panel. Inspect in-
stead the last panel 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 incor-
rect, make the correction, and then access the Commu-
nications screen by selecting Confi guration from the Main
Menu, then Confi guration, and fi nally 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 communications 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 fl ashing normally.
When all installed boards have been detected, then the
basic setup is complete. You can now move on to confi g-
uring the system operating parameters.

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 Vessel 1, to Recirculator. The fi 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 [6] key (notice that the capital R is one
of the symbols in the line right above the [6] key). A capi-
tal P will appear in the Current Character box. Continue to
press the [6] until the capital R appears there. Now press
the [Up Arrow] key, and notice that the R has been placed
on the text line in the fi rst position.
Next press the [8] key on the keypad, and continue press-
ing it until the small e appears in the Current Character
box. Press the [Up Arrow] key to place the e on the text
line. Continue entering text until you are satisfi ed with
the changes that you have made, press the [Enter] key
to accept them, and you will be returned to the previous
screen. Once all vessel names have been entered (if de-
sired), press the [Submit] key.
NOTE: If many fi elds need to be renamed, the user
can use a computer keyboard as follows:
Q4 controller - Use a keyboard with a PS2 style
connector and plug it into the socket labeled PL7
of the Q4 board.
Q5 controller - Use a keyboard with a USB style
connector and plug it into one of the two avail-
able USB connectors on the Q5 Interface board.
PANEL CONFIGURATION
Access this screen from the Main Menu. Select Confi gura-
tion > Panel Confi guration. The following screen will ap-
pear:
If a Condenser is installed, it should be enabled. The same
is true for each installed Vessel. The Panel Confi guration
screen also provides the ability to supply a unique name
for each installed Vessel. After moving the cursor to one
of the Name fi elds, press the Up Arrow key to access an
alpha/numeric data entry screen, as shown here:
The Alpha screen shows a graphic representation of the
numerical keypad. The symbols that appear above each

CONDENSER CONFIGURATION
Introduction
If a Condenser is not part of the installed system, skip
to the Vessel Confi guration. Before the Condenser
system can be effectively put into operation, certain
setup parameters must be performed and verifi ed.
The following listing shows these basic steps:
• Calibrating Sensors - The fi rst of these
steps is to calibrate all installed sensors. A
sensor that is out of calibration will cause
improper and ineffi cient operation of the
system.
• Establishing Setpoints - Setpoints need to
be set to defi ne the various ranges that the
system will control within.
• Step Confi guration – This assigns a
sequence of operation that all fans,
pumps and motors can be energized or
de-energized, in any combination, to
achieve the desired control.
• Variable Speed Fan –This allows any
installed variable speed fan to be cus-
tomized with regard to its speed and
on/off control.
• Control Overrides – Here you are able
to fi ne tune the system by allowing cer-
tain conditions to be delayed from oc-
curring until the system settles.
• Alarms – Alarms and Warnings are inevita-
ble during system setup, you may view any
alarms and clear them from here.
• Condenser Status – Once everything has
been setup, the operation of the system can
be monitored from this screen.
Calibrating Sensors
Each temperature, pressure or humidity sensor on
the Condenser must be calibrated before the system
is put into operation.
Access this screen from the Main Menu. Select Cali-
bration > Condenser:
The process used for establishing calibration values is
relatively simple. For temperature for example, it will
require a container of ice water or an infrared digital
temperature probe.
First, establish the temperature for a specifi c tem-
perature sensor. If a digital infrared measurement de-
vice is used, simply enter the calibrated temperature
into the Current Value box and press [Submit]. The
system will automatically calculate 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
Step Control
Condenser Step Control setpoints must be setup.
Access this screen from the Main Menu. Select
Setpoints > Condenser > Step Control.
These setpoints are used to confi gure the operating
characteristics for both summer and winter modes.

Step Confi guration
Fans and pumps need to be assigned to specifi c steps.
Access this screen from the Main Menu. Select Con-
fi guration > Condenser Step Confi guration:
Summer/Winter Sequence
Summer and Winter Sequence setpoints must be
setup. Access this screen from the Main Menu. Se-
lect Setpoints > Condenser > Summer Sequence (or

An identical screen will appear for Winter Sequence.
These screens allow the steps that were assigned
from the Step Confi guration screen to turn on starting
with the lowest numbered step. Steps are turned off
with the highest numbered step which is currently on,
and descend to the lowest numbered step. Steps with
the same sequence number will turn on as a group.
Steps assigned as zero will be disabled.
Variable Speed Fan
Variable Speed Fan setpoints must be setup. Access
this screen from the Main Menu. Select Setpoints >
Condenser > Variable Speed Fan.
This screen allows the user to optimize the settings
for a Variable Speed Fan.
Control Overrides
Access this screen from the Main Menu. Select Set-
points > Condenser > Control Overrides:
The high pressure and low pressure controls specify
the pressures at which all steps should be turned on
or turned off, respectively. The Low Temperature
Override permits any steps that are confi gured as
water pumps with override control to be shutdown
under low temperature conditions.
