DESCRIPTION

eration for the compressor and is useful for planning
and logging service operations. A selectable display
of “load” hours or “load” as a percent of “run” hours is
available by pressing “HR LOAD” or “HR%” respec-
tively.
SSeparator differential pressure can be dis-
played by pressing the “DP1” pad. When a differen-
tial of 10 PSID (0.7 bar) is reached, the message
“SEPARATOR MAINT RQD” is displayed and the
DP1 LED will flash.
SOil filter differential pressure can be displayed
by pressing the “DP2” pad. When a differential of 20
PSID (1.4 bar) is reached, the message “OIL FIL-
TER MAINT RQD” will be displayed and the DP2
LED will flash.
SThe “ON” LED indicates when the compressor is
running.
SThe amber light on the control panel indicates
when power to the compressor is supplied.
SThe green message display indicates the status
of the compressor.
2.3 GENERAL
While Sullair has built into this compressor a com-
prehensive array of controls and indicators to as-
sure you that it is operating properly, you will want to
recognize and interpret the reading which will call for
service or indicate the beginning of a malfunction.
Before starting your Sullair compressor, read this
section thoroughly and familiarize yourself with the
controls and indicators - their purpose, location and
use.
2.4 PURPOSE OF CONTROLS
CONTROL OR INDICATOR PURPOSE
ON/OFF PAD Depress to turn compressor ON. Depress again to turn
compressor OFF. If a fault shutdown occurs, or
EMERGENCY STOP, the ON/OFF button must be
pressed once to acknowledge the fault and silence the
alarm. Once the fault has been cleared, ON/OFF must
be pressed once to return to MANUAL SHUTDOWN in
preparation for start.
HOUR DISPLAY Displays accumulated hours of compressor operation;
useful for planning and logging service schedules. Al-
ternate displays by use of their respective touchpads
are - hours ON LOAD and percentage of hours running
when ON LOAD.
PRESSURE DISPLAY Continuously monitors service line air pressure (P2).
Located on dry side of receiver downstream of mini-
mum pressure/check valve. Selectable alternate dis-
plays via touchpad include:
SUMP PRESSURE (P1) displays sump/unit discharge
pressure.
SEPARATOR DIFFERENTIAL (DP1) displays the
differential pressure across the separator element/s. A
preset limit of 10 PSID (0.7 bar) will trigger the DP1
LED and a message will warn that a separator change
is required.
OIL FILTER DIFFERENTIAL (DP2) displays the dif-
ferential pressure across the fluid filter. A preset limit of
20 PSID (1.4 bar) will trigger the DP2 LED and a mes-
sage will warn that a filter change is required.
TEMPERATURE DISPLAY Continuously monitors the temperature of the air leav-
ing the compressor unit (T1). The normal readings
should be approximately 180ºF to 205ºF (82ºC to
96ºC). An alternate display of injection fluid tempera-
ture (T2) is available from the touchpad. Normal read-
ings should be approximately 130ºF to 160ºF (54ºC to
71ºC).
AIR FILTER MAINTENANCE Indicates when the air filter change is required. The
LED shown on the air filter of the graphic map will flash
and a message of “AIR FILTER MAINT RQD” will be
displayed.
