Frick Compressor packages may be used individually, or
in groups. This section will describe some of the various
confi gurations that may be used with regard to electrical
control.
Each individual Compressor unit is controlled by a com-
puter based machine control system, known as the Quan-
tum™ LX control panel. This controller continuously mon-
itors the conditions and operation of the compressor unit
and the various subsystems. It also directs the operation
of components. It is fully self-contained.
The Quantum™ LX control panel user interface is used to
The Quantum™ LX control panel contains all of the nec-
essary control hardware and software within one self
contained enclosure, and is mounted to the compressor
package. The front of this control enclosure contains a
graphic display and keypad to allow the operator to ac-
cess essential information and to make necessary adjust-
ments to setpoints, calibrations and features.
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 and 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 temperatures, pressures 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 to modify the units

display graphic screens, which represent various aspects
of compressor operation. By pressing a key on the key-
pad, the labeled or described function is recognized by the
control processor, and appropriate action is taken.
Although the primary means of operator interaction to
the compressor package is via the built-in Quantum™
LX control panel, there are two additional methods that
emulate the graphic control screens that may be used
remotely for compressor control. The following informa-
tion is presented to help the operator interact with these
graphic screens.
