INTRODUCTION TO THE QUANTUM™ CONTROL SYSTEM
INTRODUCTION
The Quantum™ LX panel differs from previous Quan-
tum™ 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 ve
major areas:
• Quantum™ Controller - The brains of the sys-
tem. Currently, there are two versions of Quan-
tum™ board in production, the Q4 board and
the Q5 board. Both of these boards are dis-
cussed in greater detail later in this manual.
The combination of the hardware (Quantum™
board) and the software program that runs on
it creates what we call the Quantum™ LX sys-
tem. The Quantum™ board communicates with
all of the Digital and Analog boards. This com-
munication 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 con-
trol information to the I/O boards to provide the
appropriate control of all input and output sig-
nals, based upon the conguration of installed
features and options of the compressor pack-
age. 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 communi-
cations protocols. Additional information about
the Quantum™ can be found under the QUAN-
TUM™ CONTROLLER sections found later in this
manual.
• Power Supply - Provides the necessary operat-
ing voltages for the proper operation of all con-
trol components. Additional information about
the power supply can be found under the POW-
ER SUPPLY sections 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 so-
lenoids, 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 pro-
gram 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 DIGI-
TAL BOARD section found later in this manual.
• Analog Input / Output Boards - Analog (vari-
able) signals are sent and received by these
boards. The output signals are used for control-
ling VFDs, 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™. The Analog board has 24 ana-
log inputs, and 8 analog outputs. Additional in-
formation about the Analog board can be found
under the ANALOG BOARD section found later in
this manual.
• Operator Interface - This section actually con-
sists 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 Quan-
tum™ controller such as setpoint values, calibra-
tion data, etc. Additional information about the
Display can be found under the DISPLAY section
found later in this manual.
THE CONTROL PANEL ENCLOSURE
The Frick® Quantum™ LX control panel enclosure utilizes
available space efciently and the small size allows it to
be used on all of our compressor packages. The panel is
also equipped with the necessary posts and hardware to
add options in the eld. They may also include a second
analog and/or digital board, enclosure heater and air-cir-
culating fan.
Dimensions of the standard panel are 18x22x10 inches
(WxHxD) and weighs approximately 75 pounds with all
options. Typically the panel will be mounted on the pack-
age, but it is also designed for easy wall mounting as well.
Refer to the Control Center Assembly drawing 649D5151
for the layout for this standard enclosure.
The DC power/communications harness in this panel is
color-coded. This will make wire identication much eas-
ier. The coding is as follows:
• +5VDC - RED
• +12VDC - YELLOW
• -12VDC - PURPLE
• Common/Ground - BLACK
• +RX/TX - BLUE
• -RX/TX - BLUE w/WHITE stripe
