once. The following is a list of the warning
messages.
1) CHG SEPR ELEMENT
This warning will occur if the pressure on the
Separator is 12 psig (.8 bar) greater than the

fully loaded.
2) HIGH AIREND TEMP
This will occur if the Airend Discharge Temperature
(2ATT) exceeds 221°F (105°C).

3.5 SET POINT PROCEDURE
This procedure allows the customer to modify 11
variables in the controller logic.
At this time, press the SET button to enter the
setpoint routine. The SET OFFLINE AIR
PRESSURE indicator will light and the display will
show:
XXXX PSI
OFFLINE AIR PRESSURE is the first set point and
XXXX stands for the value of the set point. Press the
SET button to select the set point to be adjusted.
Press the up or down arrow buttons to raise or lower
the set point value. Press the SET button to move to
the next set point. If the set point value has been
adjusted, press the SET button to enter the new
value. The display will flash to acknowledge.The
next set point will then be displayed. If the value of
the set point was not changed, pressing the SET
button will only step to the next set point. When the
SELECT OPTIONS set point is entered, the
SELECT OPTIONS indicator will light, and the
setpoints for options Auto Start/Stop or Remote
Start/Stop will only be accessible and displayed if
the option module is installed in the unit. The Power
Outage Restart setpoints will only be accessible and
displayed if the combination Auto/Remote
Start/Stop/Power Outage Restart option module is
installed in the unit (See Section 7.0). The set point
routine can be exited by pressing the
DISPLAY/SELECT button or exit will be automatic
after 30 sec.
The following is a list of the set points. Also included
are maximum and minimum limits, step size, and
units of measure.

** The lead/lag feature allows the customer to choose
one compressor as the “lead” compressor and any
others as the “lag” compressor (simulates the mode of
a sequencer). The lag compressor’s on-line and off-line
pressures are determined by subtracting the lag offset
set-point from the on-line and off-line pressure set-
points of the lead compressor.
