3.1 INTELLISYS CONTROLS
EMERGENCY STOP
Pressing this switch stops the compressor immediately.
The compressor can not be restarted until the switch is
manually reset. Turn the switch knob clockwise to
reset.
POWER ON LIGHT
This indicates the control voltage and the line voltage
are available for starting.
The operator panel is divided into two areas. The
bottom row of four buttons provides direct control over
the starting, stopping, unloading and loading of the
compressor. These are defined by the symbols printed
on the buttons themselves, as shown here.
START
Pressing this button will start the compressor if the
display shows “Ready To Start”. The compressor will
start and load if there is sufficient demand for air.
STOP
Pressing this button will activate the unloaded stop
sequence. If the compressor is running loaded, it will
unload and continue to run unloaded for an adjustable
10 to 30 seconds and then stop. If the compressor is
running unloaded, it will stop immediately.
UNLOAD
Pressing this button will cause the compressor to
unload and remain unloaded. The display will indicate
the machine is “Running Unloaded”, and “Mode:
UNLOAD”.
LOAD
Pressing this button will cause the compressor to load
if the compressor is running and if the “Discharge
Pressure” is less than the “Online Pressure”. This also
returns the machine to the operating mode that is
specified by the “Mode of Operation” set point.
The other five buttons provide access to various
operator-selectable functions and machine operating
conditions. The purpose of each of these buttons is
defined by the display screen and the particular
function being performed at that time.
ARROWS
These up and down buttons have multiple functions
relating to the right half of the display screen. When
lists are presented, the buttons are used to move up or
down through the items on the list. The small arrow(s)
displayed in the upper right corner of the display
screen indicate when you can move up (designated by
arrow head pointing up) and/or down (designated by
arrow head pointing down) through the list.
When the value of a specific machine operating
parameter is highlighted on the display screen for the
purpose of changing that value, the buttons are used
to change the value itself.
DISPLAY BUTTONS
The functions of the three buttons below the display
screen change and are defined by the words
immediately above them in the bottom line of the
screen. Each function, such as MAIN MENU, STATUS,
SET, etc., is described in appropriate sections in this
manual.
