THE QUANTUM™ LX CONTROL PANEL ENCLOSURE
The Frick
®
Quantum™ LX control panel enclosure has
been configured to standardize it across the entire
compressor package line.
This panel utilizes the available space efficiently. This
small size allows it to be used on all of our packages. The
panel is also equipped with the necessary posts and
hardware to add options in the field. They include a
second analog and/or digital board, enclosure heater, air-
circulating fan, and a step-down transformer for the motor
valve used on EZ-Cool™ LIOC.
Dimensions of the panel are 18x22x10 inches (WxHxD)
and weighs approximately 75 pounds with all options.
Typically the panel will be mounted on the package, but it
is also designed for easy wall mounting as well. Refer to
the Control Center Assembly drawing 649D5100 for the
layout for this standard enclosure.
The DC power/communications harness in this panel is
color-coded. This will make wire identification much
easier. The coding is as follows:
• +5vdc - RED
• +12vdc - YELLOW
• -12vdc - PURPLE
• Common/Ground - BLACK
• +RX/TX - BLUE
• -RX/TX - BLUE w/WHITE stripe
INTRODUCTION TO THE QUANTUM™ LX CONTROL SYSTEM
The Quantum™ LX panel differs from previous
Quantum™ panels primarily in the software operating
system. The hardware portion (with the exception of the
new international style keypad and cable) remains the
same. The Frick
®
Quantum™ LX control system consists
of five major areas:
• Power Supply - Provides the necessary
operating voltages for the proper operation of all
control components. Additional information about
the power supply can be found under the
POWER SUPPLY section found later in this
manual.
• Quantum™ Controller - The brains of the
system. The Quantum™ 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 the interface
screen. 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 compressor package. Operator interaction is
provided through the keypad, as well as
informational status to the display. Interaction to
the outside world is provided through industry-
standard communications protocols. Additional
information about the Quantum™ can be found
under the QUANTUM™ 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 sinals are used to sense the condition of
switches, relay contacts, auxiliary contacts, etc.
This board runs an independent software
program from the Quantum™ to control devices,
and communicates the status of all devices back
to the Quantum™. Additional information about
the Digital Boards can be found under the
DIGITAL BOARD section found later in this
manual.
• Analog Input / Output Boards - Analog
(variable) signals are sent and received by these
boards. 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™ to control devices, and
communicates the status of all devices back to
the Quantum™. There are currently two versions
of Analog board. The current version has 24
analog inputs, and 8 analog outputs, whereas it’s
predecessor had 16 analog inputs and 4 analog
outputs. Additional information about these two
board versions can be found under the ANALOG
BOARD section found later in this manual.
• Operator Interface - This section actually
consists of two major components; the Display
and the Keypad. The Display is used to show the
operator, via a graphical interface, the actual
status of all compressor values. Warnings and
shutdowns (and history/trending), pressure and
temperature values, digital I/O status, setpoints,
etc. are viewed on this display. The Keypad is
used by the operator to enter data to the
Quantum™ controller such as setpoint values,
calibration data, etc. Additional information about
the Display can be found under the
IDENTIFYING THE TYPE OF DISPLAY section
found later in this manual.
