If there are alarms active they will alternately be
shown with the default display. The machine status
will be displayed for two seconds then the alarms for
two seconds each. For example:
T1 HI
110 180a
To view other status press the
DSP
key. All tempera-
tures and pressures may be displayed as well as
other status information. To scroll through the dis-
plays press the up arrow or down arrow keys. Up ar-
row moves to the next display, down arrow the pre-
vious display. To return to the default display press
the display key.
S
Separator differential pressure and the
maximum limit. If the limit is exceeded, a
separator maintenance warning will be dis-
played.
dP 1 4
MAX 10
S
Sump pressure and line pressure.
P1 113
P2 108
S Oil filter differential pressure and the maxi-
mum limit. If the limit is exceeded oil main-
tenance warning will be displayed.
dP2 4
MAX 20
S Pressure before (P4) and after (P3) oil filter.
P3 108
P4 113
S Oil differentia l pressure and the minimum
limit. If the pressure goes below the limit a
P3 LOW shutdown will occur. Oil differential
(dP3) is defined as P3 --- P1/2
dP3 40
MIN 1
S
Unit discharge temperature and the maxi-
mum limit. If the temperature exceeds the
limit a T1 HI shutdown will occur.
T1 210
MAX 235
S Dry side discharge temperature and the
maximum limit. If the temperature exceeds
the limit a T2 HI shutdown will occur.
T2 210
MAX 235
S
Total hours that the compressor has been
running.
HRS RUN
001234.0
S
Total hours that the compressor has been
loaded.
HRS LOAD
000987.0
S
Last fault log. This shows the fault on the
first line and the run hours when the fault oc-
curred.
T1 HI
@1 234
S
Next to last fault log. This shows the fault on
the first line and the run hours when the fault
occurred.
T1 HI

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
