OVERVIEW OF OPERATOR INTERFACE
The compressor unit is controlled by a computer based
machine control system. The controller continuously
monitors the conditions and operation of the compressor
unit and the various subsystems. It also directs the
operation of components.
The panel user interface is designed to allow an operator
to efficiently access and control the operation of the
compressor unit and subsystems. The control panel
screen is used to display graphic screens. By pressing a
key on the keypad, the labeled or described function is
recognized by the control processor.
The following information is presented to help the operator
interact with the graphic screens and the Quantum™
compressor control panel. This manual is intended to
describe all presently available features for the
compressors listed in Compressor Model Differences.
Reference this section for the differences of the
compressor models that will apply to the displayed data
and the setup and setpoint entry. If applicable is used
throughout this manual to indicate when something might
apply. This is because of the compressor model (see
Compressor Model Differences) or because this feature or
option was selected from a setup.

OPERATOR ACCESS
Operator access to this system is through various screens.
A screen is the physical representation of data on the
display. Icons have been used to help an operator quickly
identify functions. An icon is a small, graphic symbol
representation. Each screen has a title area. The title is
descriptive of the screen. The current day; date and time,
is shown in this title area. The day of the week; Sunday
through Saturday (Sun. - Sat.) is displayed. The month of
the year from January to December (Jan. - Dec.) is
displayed. The day of the month from 1 to 31 and the year
from 0001 to 9999 are displayed. The time displayed is the
actual time in 24 hours (military) format. The hours,
minutes, and seconds are displayed. The labeled keys on
the panel keypad provide quick access to the operator's
needs. By pressing a labeled key on the keypad, the
corresponding function is recognized. Most of the screens
have screen keys that describe or show a function that is
recognized when the coinciding keypad key to the right of
the screen is pressed. The screen keys provide access to
other screens or commands. For easier viewing, related
information is separated into boxes. The setup and
setpoint entry is separated into logical control
components. Setup selection of features and options have
been provided to prevent the operator from unnecessary
viewing and entering of unused control settings. The
required control settings are clearly presented. To further
assist the operator, on-line help is provided. Some
selections appear faded to indicate that this feature is
unavailable. A feature can be unavailable because of
setup selections such as the compressor model. Some
selections appear faded to indicate that this feature might
be available in a future software release.
