TYPICAL SYSTEM CONFIGURATION

A typical ACUair system may control as few as one or up

to thirty-two remote panels. Each AcuAir® system oper-

ates independently of one another yet they may all be

inter-connected via a common Ethernet connection. A

system will include the Quantum™ LX AcuAir® Interface

Panel, remote panel(s), and optionally an Ethernet Hub or

Switch, and a computer with Web Browser.

The Interface Panel can then be connected to an HMI or a

remote computer. Refer to the following pictorial:

CONNECTING A COMPUTER DIRECTLY TO A QUANTUM™

LX CONTROL PANEL

Especially for the purpose of maintenance, if you wish to

connect directly to a single panel from a computer (desk-

top or laptop), you can avoid the switch and use a cross-

over Cat-5 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.

USING A WEB BROWSER (ETHERNET)

General Description

The Quantum™ LX AcuAir® user interface may be

accessed from any web browser. This feature al-

lows any screen to be viewed from a remote location

without specialized software. An Ethernet connection

to the Quantum™ LX panel must be provided to uti-

lize this feature.

The web browser interface can be viewed from any

desktop or laptop computer, which has access to

the network that the Interface panel is attached to.

Refer to the previous section entitled Connecting A

Computer Directly To A Quantum™ LX Control Panel

when setting up your network.

Setup

Access the Ethernet Conﬁ guration screen at the In-

terface Panel, by selecting Menu > Conﬁ guration >

Ethernet. The following screen will be shown:

Note the values that are displayed in the four boxes

of the IP Address.

At the computer, open the Internet browser (click on

your Internet icon). Once the browser has opened,

look for the address bar, it will appear similar to the

following:

On the address bar, type the following [ http:// ].

Do not type the brackets. After the http:// type in

the values of the four boxes from IP Address of the

Ethernet Conﬁ guration screen. Place a period (dot)

between each group of numbers. Using the screen

information example used here, the result would be

http://192.168.0.252. Your particular IP Address may

vary from the example shown.

Press the [Enter] key on your computer keyboard,

and if everything is connected and conﬁ gured prop-

erly, the Home screen of the Interface Panel should

now appear on your computer screen (similar to the

following):

If you experience problems, such as a message stat-

ing “Page not found”, consult with your IT depart-

ment.

Screen Keys

To change screens, setpoints, etc., you simply use a

mouse and the keyboard to view and change data.

All Interface screens will have several buttons on the

right hand side of the screen:

[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.

[Submit] – Although this button does not appear

in the example above, it will be present on most

screens. It is used any time that you have modi-

ﬁ ed a setpoint, or made any change to a screen.

Before leaving that screen, you must press the

[Submit] button for the changes to be saved.

AcuAir® Operator Interface Touch Screen

General Description

This optional user interface has been designed to allow

an operator to efﬁ ciently 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 dis-

play, 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 ofﬁ ce, 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 ex-

pires, the screen will change, presenting the user with

four orange targets. These targets permit the user to cali-

brate the touch screen’s mouse pointer location. If these

points are not properly set, the mouse pointer will not

appear where the user’s ﬁ nger 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 ﬁ nger 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 ﬁ nished 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 Key-

board button can be used to restart the on-screen key-

board should it disappear.

The keyboard can be used to enter text into any ﬁ eld ap-

pearing within a web page. To enter text into a ﬁ eld,

simply touch the desired ﬁ eld in the web browser. If the

ﬁ eld is properly selected, a cursor should appear within

the text ﬁ eld. The user can also drag his/her ﬁ nger over a

segment of text in the ﬁ eld to “select” it. Any key strokes

from the keyboard will then replace the highlighted text.

If the keyboard fails to transmit characters into the de-

sired text ﬁ eld, there could be one of two problems. First,

be sure the text ﬁ eld is selected. Typically the cursor is a

good indicator that focus has shifted to the desired text

ﬁ eld. The second problem involves a keyboard loss of

focus. To resolve this problem, ﬁ rst touch the desired text

ﬁ eld, then touch the [Focus] button on the bottom right-

hand corner of the keyboard, ﬁ nally touch the desired

text ﬁ eld 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 conﬁ gured

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 In-

terface 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 Ad-

min Home Page to handle various conﬁ guration 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, Pass-

word: 2staycold).

Upon entering the admin area, the user will be presented

with the list of all registered units (nothing will be dis-

played here if no units are registered). If any registered

QUANTUM™ LX AcuAir™ CONTROL PANEL

OPERATION

090.510-O (DECEMBER 12)

Page 9

units are listed, and Edit button at the end of each row

allows the user to change the speciﬁ cations of a speciﬁ c

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 Conﬁ guration

In the Admin area, the Network Conﬁ g button can be se-

lected 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 op-

tion 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 ac-

cess to the Panel from a Windows network.

Finally, the web server port can be changed from the Net-

work Conﬁ guration 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 exter-

nal web browser will access the panel through the ad-

dress: 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 notiﬁ ed when this is about to occur.

Resetting the IP Address

In the rare occurrence that a local Air Handler loses Eth-

ernet 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 set-

points being properly saved then restored (the IP address

is stored as a setpoint to the ﬂ ash 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 in-

side of the top door).

3. On the Q4 controller only, locate and temporarily

remove LK12 (on the larger board).

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 (on the Q4 only).

8. Power back up. The IP address will be auto-

matically set to 192.168.0.105. This address is

known 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.

SETUP DESCRIPTION

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 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.

▯ 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.

▯ 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 advantageous

to keep them accessible for potential maintenance

situations (reasonable lighting, sufﬁ 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 previ-

ously.

• Proceed to the section entitled Check-

ing the AC Power.

QUANTUM™ LX AcuAir™ CONTROL PANEL

090.510-O (DECEMBER 12)

Page 13

Remote 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

terminals, connection may be made to

any of them.

▯ Proceed to the section entitled Check-

ing the AC Power.

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-

energize 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

▯ Unlike the Interface Panel, the Remote 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 manu-

ally 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.

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.

TROUBLESHOOTING

The following section will help to identify some common

problems that may arise within an ACUair system. Use this

section in conjunction with the 090.510-M (Maintenance)

manual.

1. Quantum™ LX controller does not have any

LED’s lit:

• Check for the presence of 120 VAC power

at the incoming AC terminal strip. (see the

section entitled CHECKING THE AC POWER)

• Check for the presence of proper DC power

to the Quantum™ (refer to the 090.560-M

manual under the section entitled QUAN-

TUM™ LX CONTROL PANEL POWER SUP-

PLY.

• If the Quantum™ controller has proper DC

voltage applied, then with turn the control

power OFF, remove the program ﬂ ash card,

and recycle the power. If the LED’s do not

start their booting pattern, continue to the

next step.

• Try disconnecting all cables one at a time

(with the exception of the DC power). If the

LED’s start ﬂ ashing normally, then recon-

nect the removed cables one at a time, until

the problem reappears, then troubleshoot

that cable.

• If the DC power to the Quantum™ controller

is normal, and the cables from the previous

step had all been removed without correct-

ing the problem, then the board will need

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.

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.

replaced.

2. Quantum™ LX appears to boot normally, but

nothing shows on the display:

• Ensure that the display cable is securely

plugged in at both ends.

• On the Q4 only. verify that jumpers LK3 and

LK4 on the Quantum™ are set properly.

Both links should be set to position B.

• Ensure that the connectors on both ends of

backlight inverter board are plugged in se-

curely. Use caution when checking around

the inverter, as high DC voltage is present

when the control power is ON.

• Shine a ﬂ ashlight onto the display screen

at an angle. If the Quantum™ has properly

booted, you should see some text dimly

shown on the screen. If it appears as though

there IS something being displayed, but it is

not visible, then there is a problem with the

backlight, the inverter, cable or Quantum™.

INITIAL SETUP PROCEDURE

The following is a basic guide to unit setup.

1. Conﬁ guration is performed ﬁ rst. Although there

are four different Conﬁ guration screens, only the

Control Conﬁ guration needs to be setup for unit

operation.

To gain access to Control Conﬁ guration, login to

User Level 2. The following items are setup on

the two Control Conﬁ guration pages:

• Mode Conﬁ guration

• Control Temperature

• Control Source

• Supply Burner

• Heating

• Dehumidiﬁ cation

• 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-ener-

gized on a fault such as a ﬁ re.

• Cooling – Used for temperature con-

trol. The liquid valve is open because

the control temperature equals or ex-

ceeds the liquid on setpoint. If the suc-

tion valve is not a modulating valve, it is

open during cooling. During cooling, a

modulating valve regulates the suction

valve based on its setpoints.

2. Setpoints are established next. Each unit must be

setup to the customer speciﬁ c control features

and options to be used by a unit controller board.

This setup should not need to be changed by op-

erators. Setpoints are intended to be accessed

and modiﬁ ed only by a Factory Representative

or Distributor. Only those setpoints that will be

utilized for unit operation need be set. The fol-

lowing is the list of available setpoint screens:

3. Calibrate the control devices. Each sensor or

transducer that is utilized by the unit must have

its operating characteristics deﬁ ned. 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 ﬁ ne tune the de-

vice with reference to a known external calibra-

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.

OPERATOR ACCESS

Operator access to this system is through various screens.

A screen is the physical representation of data on the dis-

play. 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 modiﬁ ed. These screens typically show ana-

log values such as temperature and humidity, which are

strictly functions of an associated sensor, and as such,

cannot be modiﬁ ed. Other screens show setpoint values

which can be changed, in order modify the units operating

characteristics. For easier viewing, related information is

separated into boxes. Sometimes selections are hidden

when that the feature is unavailable.

TO CHANGE SETPOINTS

The setpoints deﬁ ne the operation and limits of each unit.

These setpoints can be change by operators in the ﬁ eld.

These setpoints are stored on the Compact Flash card.

NOTE: Setpoints are not lost after power is interrupted.

However, we suggest that a list of 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 ﬁ elds are identiﬁ ed by a black box

with a white interior. The data is shown in black

text. When on a screen that has adjustable set-

points, tab to the setpoint box that you wish to

modify (or select it on a web browser).

2. The current value of that setpoint is shown. Use

the keypad to enter the new value. Typing a new

value will completely erase the old value.

3. Press the keypad [ENTER] or [Tab] key to input

the new data in the data entry ﬁ eld and to move

to the next data entry ﬁ eld.

4. If the data entered into the setpoint box is valid,

press the keyboard [ENTER] key. After all the

setpoint changes on this screen have been en-

tered, press the [SUBMIT] button to save the

setpoint changes to memory.

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 mes-

sage. Re-enter a correct value.

The most important information about the unit is displayed. In

the middle of the screen is a diagram of an AcuAir® air han-

dling 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 ﬂ ame 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 ﬁ rst be set correctly on the Conﬁ guration

screen. Once set, the date will be automatically adjusted

for at the end of each month, much like the calendar fea-

ture of most modern watches. The primary use of the date

feature is to provide a date stamp for Warnings and Shut-

downs. 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 ﬁ rst be set correctly on the Conﬁ guration

screen. The time will also need to be adjusted for those

locations which observe Daylight Savings Time. The pri-

mary 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.
