plays 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.
S Separator differential pressure and the
maximum limit. If the limit is exceeded, a
separator maintenance warning will be dis-
played.
S Sump pressure and line pressure.
S Oil filter differential pressure and the maxi-
mum limit. If the limit is exceeded oil main-
tenance warning will be displayed.
S Pressure before (P4) and after (P3) oil filter.
S Oil differential pressure and the minimum
limit. If the pressure goes below the limit a
P3 LOW shutdown will occur. Oil differential
(∆P3) is defined as P3---P1/2
∆ P3 40
S Unit discharge temperature and the maxi-
mum limit. If the temperature exceeds the
limit a T1 HI shutdown will occur.
MAX 235
S Dry side discharge temperature and the
maximum limit. If the temperature exceeds
the limit a T2 HI shutdown will occur.
MAX 235
S Oil temperature and the maximum limit. If
the temperature exceeds the limit a T3 HI
shutdown will occur.

S Interstage temperature and the maximum
limit. If the temperature exceeds the limit a

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)
∆P1 --- (Separate differential pressure) If lit steady,
signifies that dP1 is being displayed, if flashing de-
notes replacement of separator is needed.
∆P2 --- (Oil filter differential pressure)
∆P3 --- (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.
