The MAIN MENU screen is the point from which various operator functions
can be accessed. Refer to the Operator Panel Flow Diagram.
Each of the functions can be chosen by using the up and down arrows to
highlight it on the screen.
The controller will go to the highlighted function if the SELECT button is
pressed or will return to the CURRENT STATUS screen if the STATUS button is
pressed.
Operator setpoints
Figure 18: Operator Setpoints Screen
Setpoints are user–adjustable variables in the controller logic that can be set
using the OPERATOR SETPOINTS screen.
The name and value of each of the setpoints listed below can be seen on the
screen by moving the list up and down using the arrow buttons.

Setpoints associated with options are described in the OPTIONS sections.
A setpoint’s value can be changed by first highlighting the item and its value
and pressing the SELECT button to highlight just the value. When the value
line is highlighted by itself, the value can be adjusted using the up and down
arrow buttons. The CANCEL and SET buttons appear at this time. Press the
SET button to enter the new value or press the CANCEL button to return the
value of the setpoint prior to using the arrows. The displayed value will flash
twice to indicated that it has been entered into the setpoint and the pair of
setpoint item and value display lines will again be highlighted together.
Operator set points can be exited by pressing the STATUS or MAIN MENU
buttons. If no buttons are pressed within 0 seconds, the display will return

OPTION screen.
Some options require additional compressor hardware and the correct
“Option Module” to plug into the controller. Descriptions of the options

An Option item’s value can be changed the same way that OPERATOR
SETPOINTS values are changed.
OPTIONAL FEATURES
Modulation hardware extends the control types to modulation (capacity
control) and Automatic Control System when the compressor switches
between “On-Off line’ and modulation as demand varies.
Safety of the operation is provided for as the compressor will shut down
if excessive temperatures, electrical overload conditions, or system over
pressure should occur.
LOW AMBIENT OPTION (STANDARD & ENHANCED COMPRESSORS)
When the low ambient option is installed and selected and the A/E Discharge
temperature is measured to be at or below 2˚C (5˚F), the compressor will
be started when commanded but will not load until the airend discharge
temperature is above 2˚C (5˚F). After the conditions are met the controller
will adjust the fan speed to maintain proper operating temperatures. When
the low ambient option is not installed, the compressor will not start if the
A/E discharge temperature is below 2˚C (5˚F).
NOTICE
If PORO or Scheduled Start/Stop are installed, additional hardware is
required to provide an audible warning of pending re-start . Contact
Ingersoll Rand for details .
POWER OUT RESTART OPTION (PORO)
(Dependent on installed operations and/or installed controls)
For PORO to execute , the PORO option shall be installed and the PORO
set point shall be set to ON. If power is lost to the compressor while the
compressor is running or is stopped in auto start/stop, the controller will
store the current opening conditions in memory.
When power is restored, the controller will energize the horn and start
a countdown on the display. The red LED will flash indicating a warning
condition and the horn will blow for the number of seconds set in the PORO
time set point. At the end of the countdown, the horn will stop blowing and
the compressor will start.
The PORO countdown may be stopped at any time by pressing the Stop /
Reset button on the user interface. Pressing any button will cause the horn to
stop blowing and the countdown to stop. The control will power up normally
in a ready to start mode.
