TYPICAL SYSTEM CONFIGURATION
A typical AcuAir® system may involve as few as one unit, or
nearly an infinite number of units. Each air-handling unit
within the AcuAir® system operates independently of one
another yet they may all be connected via a common
Ethernet connection. The three major parts of a system
include the air-handling unit with controller, an Ethernet
Hub or Switch, and a computer with Web Browser or an
Operator Interface Panel (HMI).
The purpose of the unit controller is of course to provide
control to the mechanics of the Air Handler. Each of these
controllers is connected to a Hub or Switch, and the
Hub/Switch is then connected to the Ethernet (which
allows the computer or HMI to view all units). The Ethernet
cables used in this configuration are all of the “straight
through” or pin-to-pin variety. Refer to the following
pictorial:
CONNECTING A COMPUTER DIRECTLY TO A PANEL
Especially for the purpose of maintenance, if you wish to
connect directly to a single panel from a computer
(desktop or laptop), you can avoid the switch and use a
crossover Cat-5 cable:
With a crossover cable, you can directly connect one
Ethernet device (computer) to the other (Quantum™
panel) without a Switch or Hub.
Refer to the following pictorial and color code table to
construct a crossover cable:

OVERVIEW OF OPERATOR INTERFACES
There are two possible methods of viewing and accessing
the user interface. One of these methods is in the form of
a standard Web Browser and the other is an optional
AcuAir® Operator Interface Touch screen.
Web Browser
The web browser interface can be viewed from any
desktop or laptop computer, which has access to the
network that an AcuAir® panel is attached to. To change
screens, setpoints, etc., you simply use a mouse and the
keyboard to view and change data.
All AcuAir® screens that are shown will have a several
buttons on the right hand side of the screen. Most screens
will have three buttons, and one setpoint box. The three
buttons are:
[Menu] – Clicking on this button will cause the main
menu to appear on the left side of the screen. Clicking
a second time will cause the menu to disappear.
[Start Refresh] [Stop Refresh] – This button(s)
appears immediately below the [Menu] button. This is
actually a toggle button, as it changes function from
Start Refresh to Stop Refresh each time it is clicked on.
When the button shows as Start Refresh, a setpoint box
will appear below it, with a time value displayed. The
time value determines how often the display screen will
refresh, or update its values. This time value is
defaulted to 5 seconds, which means that the display
will update all values shown every 5 seconds.
Depending on the network connection speed, this
updating may interfere with your ability to change data
setpoints, because the screen will refresh while you are
entering the data. To solve this, simply increase the
refresh time. The other alternative is to toggle the
Refresh Button. By pressing [Stop Refresh], screen
refreshing will terminate, and the time setpoint box will
reappear. In this state, the particular screen that you
are viewing will never update the displayed values.
Changing to another screen will show the most recent
values on the new screen, and then will not update
again. So in the Stop Refresh state, screens will only be
updated when new screens are accessed. This feature
should not be used when monitoring for data. Try to find
an acceptable refresh time for the Start Refresh state.
One screen that DOES NOT have these buttons is:
Software Maintenance – To leave this screen,
click on [Exit] button. Note: Using the [Exit]
button takes several seconds, and it will force the
password level back to zero.
There are numerous screens that have additional
buttons to those mentioned here. These additional
buttons are self-intuitive, and as such, are not
discussed here.
S90-512 O (MAR 08) FRICK® QUANTUM™ LX AcuAir®CONTROL PANEL
Page 6 OPERATION – SERVICE
AcuAir® Operator Interface Touch Screen
General Description
This optional user interface has been designed to
allow an operator to efficiently access, control and
monitor the operation of all Frick AcuAir® units from a
single access point, when all units are connected
through a common Ethernet network. The touch
screen control panel is used for graphic displays. By
touching an active area of the display, a data entry
box will appear, allowing the operator to enter
different setpoint values, via a keyboard overlay, that
will appear on the screen. The Operator Interface
panel provides a platform to easily navigate between
all networked control systems, as well as a remote
access point which is reachable from any desktop
web browser. Remote access provides users with the
ability to connect to Frick control systems from both
home and office, or any other location providing
Internet access.
Touch Screen Calibration
When the panel completes it boot sequence, the user
will be presented with a message box which requests
the user to touch the screen to enter calibration mode.
If the user touches the message box before the 3-
second timer expires, the screen will change,
presenting the user with four orange targets. These
targets permit the user to calibrate the touch screen’s
mouse pointer location. If these points are not
properly set, the mouse pointer will not appear where
the user’s finger makes contact with the screen. Once
the screen’s calibration target appear, it is best to use
a dull pointed object to touch each of the four targets,
as a finger makes contact with an area too large to
provide accurate calibration.
Browser and Keyboard
Both the browser and keyboard should appear on the
screen once the panel has finished its startup
sequence. Each panel is equipped with a program
which will restart the keyboard and browser if either
application is closed. The browser has a small icon in
the center of the top tool bar, which permits the user
to return to the panel Home Page at any time. From
the panel Home Page, the Keyboard button can be
used to restart the on-screen keyboard should it
disappear.
The keyboard can be used to enter text into any field
appearing within a web page. To enter text into a
field, simply touch the desired field in the web
browser. If the field is properly selected, a cursor
should appear within the text field. The user can also
drag his/her finger over a segment of text in the field
to “select” it. Any key strokes from the keyboard will
then replace the highlighted text.
If the keyboard fails to transmit characters into the
desired text field, there could be one of two problems.
First, be sure the text field is selected. Typically the
cursor is a good indicator that focus has shifted to the
desired text field. The second problem involves a
keyboard loss of focus. To resolve this problem, first
touch the desired text field, then touch the [Focus]
button on the bottom right-hand corner of the
keyboard, finally touch the desired text field a second
time. After this sequence, characters should be
directed to the correct location. This three-step
sequence should be used whenever the keyboard
appears unresponsive.
Keyboard Overlay
Home Page
The panel Home Page displays all the units
accessible through the Operator Interface Panel. Any
FRICK® QUANTUM™ LX AcuAir® CONTROL PANEL S90-512 O (MAR 08)
OPERATION - SERVICE Page 7
configured units will appear with an icon and a
descriptive label. If an icon is touched, the web
browser will be directed to the Quantum LX control
page. To return to the Operator Interface Panel’s
Home Page simply touch the “Home” icon on the
browser’s toolbar.
Admin Home Page
The Operator Interface Panel is equipped with the
Admin Home Page to handle various configuration
functions. This area can be accessed by pressing the
Admin button on the panel’s Home Page. As user
name and password are required to access this area
(Username: admin, Password: 2staycold).
Upon entering the admin area, the user will be
presented with the list of all registered units (nothing
will be displayed here if no units are registered). If any
registered units are listed, and Edit button at the end
of each row allows the user to change the
specifications of a specific unit. A row of Admin
buttons across the top of the page allow the user to
add new units, or delete units from the list of
registered units. Each unit must have a unique name
(no two units can have the same name) and an IP
address (the IP address is not required to be unique,
so more than one link can redirect the user to the
same unit). The user can also select the type of unit
which results in an appropriate icon being displayed
on the panel Home Page where all units are listed.
Network Configuration
In the Admin area, the Network Config button can be
selected to modify the Operator Interface Panel’s
network settings. When the page is loaded, the
current network settings are displayed for the user to
view. It is possible to change the IP address, subnet
mask, and default gateway. The IP address type can
be static or dynamic; the later option requires a DHCP
server to be present. Please consult a network
administrator to modify the values correctly. It is also
possible to specify a network name, allowing access
to the Panel from a Windows network.
Finally, the web server port can be changed from the
Network Configuration page. This is traditionally set
to 80 which all web browsers understand to be the
default port. If this is changed to any other value, the
panel can only be reached from an external computer
by appending the port number to the IP address (e.g.
if the Panel’s IP address is 192.168.0.5 and the web
server port is 400, an external web browser will
access the panel through the address:
192.168.0.5:400). If this panel does not need to be
reached from an external computer, then the web
server port setting should be disregarded.
In the event the web server port or IP address settings
are changed, the panel may need to perform a reboot
before these changes take effect. This it will do
automatically, and the user will be notified when this is
about to occur.
Resetting the IP Address
In the rare occurrence that a local Air Handler loses
Ethernet communications with the Web Browser or
Operator Interface Panel, it could be that the unit has
an invalid IP address. One way that this could happen
would be if the unit has just had a program upgrade,
without the setpoints being properly saved then
restored (the IP address is stored as a setpoint to the
flash card).
In order to correct this situation, perform the following
steps:
1. Power down the failing unit.
2. Locate the processor board (located on the
inside of the top door).
3. On the processor board (the larger of the two
boards), locate and temporarily remove
LK12.
4. Power the unit up.
5. Wait for one minute to allow the processor to
fully boot.
6. Power the unit down.
7. Replace LK12.
8. Power back up. The IP address will be
automatically set to 192.168.0.105. This
address is know to work, and should solve
the problem. At this point, the unit should
show up at the Web Browser or Interface
panel (HMI). If the user wishes, they may
now go into the HMI and modify the IP
address for the unit in question to the
number that they need it to be, or they may
leave it alone.
If the above steps fail to bring the unit back into the
network, you should check the Ethernet cables, hub
or switch, Quantum™ control board, etc.
S90-512 O (MAR 08) FRICK® QUANTUM™ LX AcuAir®CONTROL PANEL
Page 8 OPERATION – SERVICE
OPERATOR ACCESS
Operator access to this system is through various screens.
A screen is the physical representation of data on the
display. Icons have been used to help an operator quickly
identify functions. An icon is a small graphic symbol
representation. Each screen has a title area. The title is
descriptive of the screen. The current date and time is
shown in this title area. The day of the week, Sunday
(Sun.) through Saturday (Sat.) is displayed. The month of
the year from January (Jan.) to December (Dec.) is
displayed. The day of the month from 1 to 31 and the year
from 0001 to 9999 is displayed. The time displayed is the
current time in 24 hours (military) format. The hours,
minutes and seconds are displayed.
Some screens are for informational purposes only, and
cannot be modified. These screens typically show analog
values such as temperature and humidity, which are
strictly functions of an associated sensor, and as such,
cannot be modified. Other screens show setpoint values
that allow the operator to change, in order modify the units
operating characteristics. For easier viewing, related
information is separated into boxes. To further assist the
operator, an on-line help is provided. Sometimes
selections appear differently (a box may be dimmed) to
indicate that the feature is unavailable.
TO CHANGE SETPOINTS
The setpoints define the operation and limits of each air
unit. Adjustable setpoints are setpoints that an operator
can easily change in the field. These setpoints are stored
in EPROM (non-volatile memory).
NOTE: Adjustable Setpoints are not lost after power is
interrupted. However, we suggest that a list of Adjustable
Setpoints be recorded and stored safely to facilitate
reentry, in case there is a need to return to the original
settings.
1. The data entry fields are identified by a black box
with a white interior. The data is shown in black
text. When on a screen that has adjustable
setpoints, select the setpoint box that you wish to
modify (either by touching that box if a touch-
screen or selecting it with a mouse for a web
browser). Once the data field has been selected,
the background turns blue, and the text turns
white.
2. The current value of that setpoint is shown. Use
the keyboard to enter the new value. Typing a
new value will completely erase the old value.
3. Press the keyboard [ENTER] key to input the
new data in the data entry field and to move to
the next data entry field.
4. If the data entered into the setpoint box is valid,
then once you have pressed the keyboard
[ENTER] key, the [SUBMIT] box in the lower left
hand side of the viewing screen will turn from a
grey background, to a red background. Press the
[SUBMIT] button to load the changed setpoint to
the controller.
5. If the value is out of bounds, an error message
box displays the proper range of values. Press
the [OK] button to acknowledge the error
message. Re-enter the correct value.
When finished making any changes to the data on an
adjustable setpoint display press the [SUBMIT] key to
accept all changes.

Page 10 OPERATION – SERVICE
INITIAL SETUP PROCEDURE
The following is a basic guide to unit setup.
1. Configuration is performed first. Although there
are four different Configuration screens, only the
Control Configuration needs to be setup for unit
operation.
To gain access to Control Configuration, login to
User Level 2. The following items are setup on
the two Control Configuration pages:
• Mode Configuration
• Control Temperature
• Control Source
• Supply Burner
• Heating
• Dehumidification
• Damper
• Exhaust
• Exhaust Control
• Exhaust Fan Run Warning
• Supply Fan
• Room Pressure
• Pre-Coil Override
• Discharge Temperature
• Desiccant Heat Source
• Defrost
• Defrost Initiation
• Air Defrost
• Smoke Detector – Enables or Disables
the input for a Smoke Detector. For fail-
safe operation, this input is energized
when there is no problem and de-
energized on a fault such as a fire.
• Cooling – Used for temperature control.
The liquid valve is open because the
control temperature equals or exceeds
the liquid on setpoint. If the suction valve
is not a modulating valve, it is open
during cooling. During cooling, a
modulating valve regulates the suction
valve based on its setpoints.
• Pre-Wheel Cooling
2. Setpoints are established next. Each unit must be
setup to the customer specific control features
and options to be used by a unit controller board.
This setup should not need to be changed by
operators. Setpoints are intended to be accessed
and modified only by a Factory Representative or
Distributor. Only those setpoints that will be
utilized for unit operation need be set. The
following is the list of available setpoint screens:
Temperature
• Cooling
• Supply Burner
• Heating
• Pre-Wheel Cooling
Dehumidification
• Desiccant Wheel
• Wheel / Regen Fan
• Regen Burner
Supply Air Flow
• Supply Fan

• Digital Outputs
Panel
3. Calibrate the control devices. Each sensor or
transducer that is utilized by the unit must have
its operating characteristics defined. This is
where the controller is told what each devices
high and low operating ranges are, as well as
offsets. The offsets are used to fine tune the
device with reference to a known external
calibration device:
• Temperature
• Pressure
• Miscellaneous
• Auxiliaries
• Analog Outputs
4. From Security Setup, establish the desired
access rights of the operators.
The panel now provides quick access to the most
important information and controls of the units and their
subsystems.

GRAPHIC SCREENS
OPERATING STATUS
The most important information about the unit is displayed.
In the middle of the screen is a diagram of an AcuAir® air
handling unit that shows the current state of the unit. The
graphic simulation shown on the screen will vary
depending upon the installed options. The following items
may be shown:
• The supply fan and both exhaust fans spin.
• A flame is displayed when the burner is on.
• The cooling coils are colored blue when they are on,
white when they are off and red when in defrost.
The following information is shown on this screen:
DATE - The actual date will be displayed in this box.
The date must first be set correctly on the
Configuration screen. Once set, the date will be
automatically adjusted for at the end of each month,
much like the calendar feature of most modern
watches. The primary use of the date feature is to
provide a date stamp for Warnings and Shutdowns.
Refer to the section entitled Setting the Date and
Time for further information.
TIME - The actual time will be displayed in this box.
The time must first be set correctly on the
Configuration screen. The time will also need to be
adjusted for those locations which observe Daylight
Savings Time. The primary use of the time feature is
to provide a time stamp for Warnings and Shutdowns.
Refer to the section entitled Setting the Date and
Time for further information.
SCREEN TITLE - This is the title for the screen that is
showing. Each screen will have a title. The
Quantum™ LX manuals will extensively refer to
screens by these names. When referred to in these
manuals, screen names will be shown in bold italic
print, such as Operating Status.
MODE OF OPERATION – The current mode of the
unit, either Cleanup or Process.
• Process 1 and Process 2 – The unit is
maintaining optimum air conditions for
processing product.
• Cleanup - The unit is modifying air
conditions to support the cleanup procedure.

USER DEFINED OPERATING STATUS
SCREEN NAME: User Defined.
ACCESSING:
DESCRIPTION: The purpose of this screen is to allow the user to assign additional analog channels to be more readily
viewable. Since the main Operating Status (Home) screen is capable of only showing a limited number of pre-assigned
analog values, it may be desirable for the user to have a method of viewing additional information that they can select, on a
common screen. They may even select values that are already being displayed on the Operating Status screen, as well
as values that are not shown there.
This screen is provided to allow the user to view up to 20
different analog channels of their choosing.
As an example of how this screen works, assume that in
addition to the data that is shown on the Operating Status
screen, the user would like to monitor the Outside Air
Temperature, Room Air Humidity and Pre-coil Air
Temperature, all on the same screen (this one). Notice that
Outside Air Temperature and Room Air Humidity are already
shown on the Operating Status (Home) screen, but the Pre-
coil Air Temperature is shown on the Operating Status 2
screen. In order to set this screen up to show these three
values, the user would highlight the Enable User Defined
Channel 1 (or whatever channel they wish to use), by
selecting it with the mouse. Once the box is highlighted, click
on it to cause the possible settings for the channel to appear.
Use the mouse to scroll through the list. When the selection
that you want to use has been highlighted, click on it to select
it. Once selected, a value will appear to the right of the list,
which corresponds to the analog value for that channel.
The following selections may be shown on this screen:
Outside Air Temperature
• Discharge Air Temperature
• Room Air Temperature
• Return Air Temperature
• Pre-Coil Air Temperature
• Coil Air Temperature
• Room Air Humidity
• Room Pressure

OPERATING VALUES – OPERATING STATUS 2
SCREEN NAME: Operating Status 2.
ACCESSING:
DESCRIPTION: The Operating Status 2 screen shows additional unit information.
The Operating Status 2, displays additional information
that cannot be shown on the first Operating Status
screen. Along the sides of the page are labels identifying
the various areas of the screen.
The following information is shown on this screen:
DATE - The actual date will be displayed in this box.
The date must first be set correctly on the
Configuration screen. Once set, the date will be
automatically adjusted for at the end of each month,
much like the calendar feature of most modern
watches. The primary use of the date feature is to
provide a date stamp for Warnings and Shutdowns.
TIME - The actual time will be displayed in this box.
The time must first be set correctly on the
Configuration screen. The time will also need to be
adjusted for those locations which observe Daylight
Savings Time. The primary use of the time feature is
to provide a time stamp for Warnings and Shutdowns.
SCREEN TITLE - This is the title for the screen that is
showing. Each screen will have a title. The
Quantum™ LX manuals will extensively refer to
screens by these names. When referred to in these
manuals, screen names will be shown in bold italic
print, such as Operating Status.
ID - The number that has been assigned to this
particular unit on the Communications Setup screen.
RUN HOURS – The total number of hours that the Air
Handler has run since the unit was installed.
WARNING/SHUTDOWN STATUS BOX - The
Warning/Shutdown Status is displayed below the
Mode of Operation status box. This status box is
blank with no message if there are no warnings or
shutdowns present.
If a Warning or Shutdown occurs, a message will be
shown, identifying the type of warning or shutdown. The
definitions for the two types of messages are as follows:
WARNING - A specific warning message will be
shown when a warning is present. A warning is a
condition that requires operator acknowledgement
but allows the Unit to continue to run if it is already
running. A Warning message indicates that a
warning setpoint has been reached, or exceeded.
SHUTDOWN - This specific shutdown message will
be shown when a shutdown is present. A shutdown
is a condition that requires an operator to
acknowledge, and causes the Unit to shut down. A
Shutdown message indicates that a shutdown
setpoint has been reached, or exceeded.
To clear a Warning or Shutdown, the operator must
access the Current Safeties screen, and
acknowledge the Warnings/Shutdowns by pressing
the [Clear Safeties] button. If the conditions that
originally caused the Warning or Shutdown have not
been corrected, the Warning or Shutdown will

SAFETIES - Current Safeties
SCREEN NAME: Current Safeties.
ACCESSING:
DESCRIPTION: The Current Safeties screen shows the Warnings and Shutdowns that have recently occurred (up to 50).
When a warning or shutdown is triggered, a blue descriptive message shows on this screen. The date and time of the
warning or shutdown occurrence is shown to the right of its description. The most recent message will appear on the top
line of the screen with the oldest appearing at the bottom. When a Warning or Shutdown is logged to this screen, it will
also be logged to the Safety History screen.
The following Current Safeties screen key is provided:
[Clear Safeties] - Selecting this key will clear all
warnings and/or shutdowns from this screen. This will
also place a date/time stamp for the corresponding
entry on the Safety History screen showing that the
particular Warning or Shutdown was cleared. Clearing
the entry on the Current Safeties screen, will not
clear it from the Safety History screen.
To resume normal operation it will be necessary to go
through the following steps:
1. Correct the condition(s) causing the warning.
2. Press the [ALARM SILENCE] key. (This action
may precede correcting the condition(s) causing
the warning). Or, go to step 3.
3. To clear or reset the Warnings/Shutdowns
screen and turn off any warning annunciation
device, from the screen, press the [Clear
Safeties] key. This will also clear the WARNING
or SHUTDOWN message from the Operating
Status screen.
4. If the conditions causing the warning have not
been corrected or a new fault has occurred, a
new WARNING or SHUTDOWN message will
appear. The Safety History screen keeps a
record of the warnings and shutdowns. This
information will help troubleshoot persistent
operational problems.
Refer to the Warnings/Shutdowns Message section for a
list of all the possible conditions.

associated Freeze (Operating Status) screen.
Freeze Screen Description
This Freeze screen provides a snapshot of the values that
were current at the time of the latest shutdown. The
information on the Freeze screen can help the user to
identify the cause of a fault, which occurred when no one
was present. The Freeze screen freezes the information
of the Operating Status screen AT THE MOMENT OF A
AIR HANDLER WARNING OR SHUTDOWN. The Freeze
screen has the same appearance and contains the same
information as the Operating Status screen. (For a
description of the information presented by the Freeze
screen, refer to the Operating Status screen). The
Freeze screen will retain the information generated by a
warning or shutdown. The last fifty warnings/shutdowns
Freeze screens are saved. This data is saved during a
power outage.

SYSTEM STATUS - Trending - Trending Setup
SCREEN NAME: Trending Setup.
ACCESSING:
DESCRIPTION: This is the Trending Setup screen. Up to eight channels can be monitored in real time trending, and up to
eight channels monitored in history trending.
Real Time Trending - is a method by which the user can
set the Quantum™ LX to map real-time events to a
graphic chart format. Using this feature allows for a live
snap-shot of recent unit process characteristics, such as
temperature, pressure and humidity readings. The events
that occur will scroll across the screen from left to right, at
a speed that is determined by the recording interval. Real
Time trending information is also stored to a log file, which
provides a time/date stamp for each of the selected
channels, as well as the value of the reading for that
channel. This log file can be viewed on the Real Time
Data Log screen. Trending data is lost upon power cycle.
The following setpoints are provided:
Real Time Recording Interval – The time interval
that defines how often the real time trending data
values are updated. This value may be set for any
time duration between 1.0 second and 86,400.0
seconds (24 hours).
History Trending - is a method by which the user can set
the Quantum™ LX to record historical events to a graphic
chart format. This feature is similar to Real Time trending,
except that the data points can be set separately, the rate
at which the graphic chart is updated can be set to a
different rate, and the data is not lost at power cycle. Using
this feature allows for the recording of recent event
characteristics, such as temperature, pressure and
humidity readings. The events that occur will scroll across
the screen, at a speed that is determined by the recording
interval.
History Recording Interval – The time interval that
defines how often the history trending data values are
updated. This value may be set for any time duration
between 1.0 minute and 60.0 minutes (1 hour).
To program this screen with the data you wish to trend,
highlight the Enable Real Time Trend Channel 1 (or
whatever channel you wish to use), by selecting it with the
mouse. Once the box has been selected, a drop down
menu will appear for that channel. On the right hand side
of the drop down box will be an arrow. Selecting the arrow
will to cause all the possible settings for the channel to
appear. Use the mouse to scroll through the list. When the
selection that you want to use appears, click on it to select
it. Once selected, the value for this channel will be
automatically trended and shown on the Real Time
Trending graph (or History Trending Graph), as well as on
the Real Time Trending Data Log (Or History Trending
Data Log).
