4.5 OPERATING MODES
The Operating Mode is the manner in which the
machine operation is being controlled. There are five
Operating Modes: AUTOMATIC, MANUAL, OFF,
FAULT, and UI COMM.
The active operating mode of the compressor
appears on the lower line of the display screen’s
Normal View. See
Figure 4-5 .
The compressor operating modes are described
below:
Automatic mode— Indicated by the word
AUTOMATIC appearing in the lower line of the
display window. This is a user selected mode that
sets the compressor motor to automatically start
when conditions necessitate and stop when motor
operation is not required.
Manual Mode— Indicated by the word MANUAL
appearing in the lower line of the display window.
This is a user selected mode that allows the operator
to manually control the compressor motor operation.
When the START pad is pressed while in
Manual Mode the compressor motor will run
continuously until the STOP pad is pressed.
The compressor pump and all other machine
parameters function the same in both Manual and
Automatic modes.
Off mode— Indicated by the word OFF appearing in
the lower line of the display window. This mode
indicates that the compressor and motor have been
turned off under normal conditions. When in this
mode the machine will not operate until the START
pad is pressed.
Fault mode— Indicated by the word FAULTED
appearing in the lower line of the display window.
This mode indicates that a machine problem has
occurred causing the controller to shut down the
machine until the condition is cleared. After a fault
condition has been resolved, the fault indication can
be cleared from the controller by pressing the STOP
pad. Refer to Section 5: Troubleshooting on
page 27, for information on resolving fault conditions.
UI Comm mode— Indicated by the word UI COMM
appearing in the lower line of the display window.
This mode indicates that the User Interface has lost
communication and, as a result, the machine
operating mode or status is unknown.
4.6 OPERATING STATES
Operating States describe the state of the
compressor operation in response to the current
mode and current conditions. Essentially, the
operating state is what the machine is doing at a
particular moment. Most operating states occur
automatically as normal functions of the compressor
and require no direct action from the operator.
Text descriptions of operating states appear
periodically on the lower line of the display screen
while in Normal View. See
Figure 4-6 . The leading
line will read “The Compressor is” below which the
operating state description will be displayed.
