To view other status press the DSP key. All tem-
peratures and pressures may be displayed as well
as other status information. To scroll through the
displays press the up arrow or down arrow keys. Up
arrow moves to the next display, down arrow the
previous display. To return to the default display
press the display key.
• Separator differential pressure and the maximum
limit. If the limit is exceeded, a separator mainte-
nance warning will be displayed.
• Sump pressure and line pressure.
• Oil filter differential pressure and the maximum
limit. If the limit is exceeded oil maintenance warn-
ing will be displayed.
• Pressure before (P4) and after (P3) oil filter.
• Oil differential pressure and the minimum limit. If
the pressure goes below the limit a P3 LOW shut-
down will occur. Oil differential (dP3) is defined as
P3-P1/2.
• Unit discharge temperature and the maximum
limit. If the temperature exceeds the limit a T1 HI
shutdown will occur.
• Dry side discharge temperature and the maximum
limit. If the temperature exceeds the limit a T2 HI
shutdown will occur.
• Total hours that the compressor has been running.

6.4 LAMP INDICATORS

Embedded into the front panel schematic of the
compressor are several lamps. Pressing the lamp
test key will light all the lamps for 3 seconds. Each
LED lamp has the following purpose.
P1 - (Sump and line pressure) If lit steady, signifies
that P1 is being displayed, if flashing denotes the
presence of an alarm.
P2 - (Sump and line pressure) If lit steady, signifies
that P2 is being displayed, if flashing denotes the
presence of an alarm.
P3 - (Pressure after oil filter) Same as P1 & P2 ex-
cept for P3. (Pressure after oil filter).
P4 - (Pressure before oil filter).
dP1 - (Separator differential pressure) If lit steady,
signifies that dP1 is being displayed, if flashing de-
notes replacement of separator is needed.
dP2 - (Oil filter differential pressure).
dP3 - (Oil differential pressure).
T1 - (Dry side discharge temperature) If lit steady,
signifies that T1 is being displayed, if flashing de-
notes the presence of an alarm.
T2 - (Discharge temperature) If lit steady, signifies
that T2 is being displayed, if flashing denotes the
presence of an alarm.
MOTOR - If flashing, indicates the motor overload
contact has opened.
INLET FILTER - If flashing, indicates that inlet filter
maintenance is needed.
