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 -- (Separate 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.
T3 -- (Oil temperature) If lit steady, signifies that T3 is
being displayed, if flashing denotes the presence of
an alarm.
T4 -- (Interstage temperature) If lit steady, signifies
that T4 is being displayed, if flashing denotes the
presence of an alarm.
T5 -- (Package discharge temperature)
MOTOR -- If flashing, indicates the motor overload
contact has opened.
INLET FILTER -- If flashing, indicates that inlet filter
maintenance is needed.
OIL FILTER -- If flashing, indicates that oil filter
maintenance is needed.
