INTRODUCTION TO THE QUANTUM™ CONTROL SYSTEM
INTRODUCTION
The Quantum™ LX panel differs from previous Quantum™
panels primarily in the software operating system. The hard-
ware portion (with the exception of the new international style
keypad and cable) remains the same. The Frick® Quantum™
LX control system consists of fi ve major areas:
• Quantum™ Controller - The brains of the system.
Currently, there are two versions of Quantum™ board
in production, the Q4 board and the Q5 board. Both
of these boards are discussed 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 system. The Quan-
tum™ board communicates with all of the Digital and
Analog boards. This communication allows the Quan-
tum™ to read the status of all the I/O boards, and
display the data on the interface screen. The Quan-
tum™ 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 confi guration 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-stan-
dard communications protocols. Additional informa-
tion about the Quantum™ can be found under the
QUANTUM™ CONTROLLER sections found later in
this manual.
• Power Supply - Provides the necessary operat-
ing voltages for the proper operation of all control
components. Additional information about the power
supply can be found under the POWER SUPPLY sec-
tions found later in this manual.
• Digital Input / Output Boards - Digital (on/off) sig-
nals are sent and received by these boards. The out-
put signals are used for energizing solenoids, valves,
contactors, relays, etc., and the input signals are
used to sense the condition of switches, relay con-
tacts, auxiliary contacts, etc. This board runs an in-
dependent software program from the Quantum™ to
control devices, and communicates the status of all
devices back to the Quantum™. Additional informa-
tion 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 VFDs, modu-
lated valves, etc., and the input signals are used to
read the values being sent from pressure transduc-
ers, temperature sensors, etc. This board runs an in-
dependent software program from the Quantum™ to
control devices, and communicates the status of all
devices back to the Quantum™. The Analog board
has 24 analog inputs, and 8 analog outputs. Ad-
ditional information 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 effi ciently 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 fi 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 identifi cation 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
GENERAL INFORMATION
The components within the control panel can be inad-
vertently damaged by static electricity or mishandling.
Only qualifi ed technicians should directly handle these
components.
1. DO NOT attempt to make corrections to the
power supply without shutting off the power to
the control panel. Accidental shorts can irrepa-
rably damage the processor boards or the dis-
play screen.
