SThe hour display records cumulative hours of
operation forthe compressor and is useful forplan-
ning 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%” respectively.
SSeparator differential pressure can be dis-
played by pressing the “ΔP1” pad. When a differ-
ential of 10 PSID (0.7 bar) is reached, the message
“SEPARATOR MAINT RQD” is displayed and the
ΔP1 LED will flash.
SOil filter differential pressure can be displayed
by pressing the “ΔP2” pad. When a differential of
20PSID(1.4bar)isreached, themessage “OILFIL-
TER MAINT RQD” will be displayed and the ΔP2
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 mal-
function. Before starting your Sullair compressor,
read this section thoroughly and familiarize your-
self 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 SHUT-
DOWN in preparation for start.
HOUR DISPLAY Displays accumulated hours of compressor opera-
tion; useful for planning and logging service sched-
ules. Alternate 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 dis-
charge pressure.
SEPARATOR DIFFERENTIAL (ΔP1) displays the dif-
ferential pressure across the separator element/s. A
preset limit of 10 PSID (0.7 bar) will trigger the ΔP1
LED anda message will warn that a separator change
is required.
OIL FILTER DIFFERENTIAL (ΔP2) displays the dif-
ferential pressure across the fluid filter. A preset limit
of 20 PSID (1.4 bar) will trigger the ΔP2 LED and a
message will warn that a filter change is required.
TEMPERATURE DISPLAY Continuously monitors the temperature of theair leav-
ing the compressor unit (T1). The normal readings
should be approximately 180_F to 205_F(82
_Cto
96_C). An alternate display of injection fluid tempera-
ture (T2) is available from the touchpad. Normal read-
ings should be approximately 130_F to 160_F(54
_C
to 71_C).
AIR FILTER MAINTENANCE Indicates when the air filter change is required. The
LED shown onthe air filter ofthe graphic map willflash
and a message of “AIR FILTER MAINT RQD” will be
displayed.
