INTRODUCTION TO THE QUANTUM™ LX AcuAir
CONTROL SYSTEM
The Quantum™ LX AcuAir
panel differs from previous
AcuAir
panels. Version 2.0x and earlier used a LCD
display and keypad, mounted to a central control panel,
which was capable of controlling up to four Air Handlers.
The Quantum™ LX AcuAir
version 3.0x and later, utilizes
networking capabilities, which greatly increases the total
number of Air Handlers that may be connected to the
system. This number is technically unlimited. The network
can be viewed remotely through any web browser, or the
optional Frick
AcuAir
Operator Interface Panel (see
S90-512 O for further information).
The Frick
®
Quantum™ LX control system consists of the
following major areas:
•
Control Panel Enclosure
- The Frick
®
Quantum™ LX AcuAir
®
control panel enclosure is
configured to make it as standardize as possible.
Since there are nearly an infinite number of
possible configurations and options, this manual
will describe the most common features and
arrangements. It is always best to refer to the
wiring diagrams, panel layouts, and operational
documentation that is included with each unit for
exact details regarding equipment operation.
Power Supply
- Provides the necessary
operating voltages for the proper operation of all
control components. Additional information about
the power supply is located under the
POWER
SUPPLY
section found later in this manual.
Quantum™ 4 Controller
- The Quantum™ 4
board runs a software program that
communicates with all of the Digital and Analog
boards. This communication allows the
Quantum™ to read the status of all the I/O
boards, and display the data on either a Web
Browser, or the optional Operator Interface
Panel. The Quantum™ acts on this data, and
provides the necessary control information to the
I/O boards to provide the appropriate control of
all input and output signals, based upon the
configuration of installed features and options of
the Air Handler package. Interaction to the
outside world can be achieved through industry-
standard communications protocols. The
combination of the Quantum™ 4 control board,
and the specific software program that it runs, is
known as the Quantum™ LX. Additional
information is located under the
QUANTUM™ 4
CONTROLLER
section found later in this
manual.
Digital Input / Output Boards
- Digital (on/off)
signals are sent and received by these boards.
The output signals are used for energizing
solenoids, valves, contactors, relays, etc., and
the input signals are used to sense the condition
of switches, relay contacts, auxiliary contacts,
etc. This board runs an independent software
program from the Quantum™ LX to control
devices, and communicates the status of all
devices back to the Quantum™ LX. Additional
information about the Digital Boards is located
under the
DIGITAL BOARD
section found later in
this manual.
Analog Input / Output Board
- Analog (variable)
signals are sent and received by this board. The
output signals are used for controlling damper
motors, modulated valves, etc., and the input
signals are used to read the values being sent
from pressure transducers, temperature sensors,
etc. This board runs an independent software
program from the Quantum™ LX to control
devices, and communicates the status of all
devices back to the Quantum™ LX. The analog
board contains 24 analog inputs, and 8 analog
outputs. Additional information about these two
board versions is located under the
ANALOG
BOARD
section found later in this manual.
Operator Interface
– As defined earlier, the
operator can access the control information
through two possible methods: a web browser or
the optional Operator Interface Panel. Both
interface methods perform the same task. They
allow the operator to monitor and modify the
operating parameters of any attached AcuAir
Air
Handling units. With the Web Browser method of
interface, the operator uses the keyboard and
mouse of the computer that the Web Browser is
running on. In the case of the Interface Panel,
there is no physical keyboard or mouse, but the
display is a touch-screen, which allows the
operator to physically touch areas of the screen,
and using a finger they can maneuver a mouse
pointer around. Data and text are entered
through a virtual onscreen keyboard.
