has a change coolant filter warning, and the coolant
filter pressure drop (5CPT - 6CPT) is greater than 35
psi (2.41 Bar).
Recommended Checks

Replace oil filter according to PM schedule.

Are the sensors reading 0 psi (0 Bar) when the
machine is not running? Correct/calibrate sensors.

If the sensors readings are fluctuating rapidly, there
is a short, ground or electrical noise from a power
cable (blower motor, drain valve)

Take oil sample for contaminated environments.

Check wiring of the sensors in P5 terminal.
High Inlet Vacuum
Xe Software Logic for R & RS machines:
This will occur if the compressor is running loaded and
the inlet vacuum is greater than 1.8 psi (.12 Bar). If the
compressor has a high dust filter, the trip threshold for
inlet vacuum is 2.4 psi (1.7 Bar). This logic only checks
1AVPT sensor when the machine is loaded or running
in modulation.
