4.2. Parameters description
P01 – High plant pressure alarm
• Defines the limit of plant pressure. Over this value, the compressor goes in shutdown fault and a A12
message is shown on the display.
• No adjustment is necessary.
P02 – Unload pressure
• Defines the value of plant pressure, in load state, that the compressor must to reach to go in a unload
phase. In unload phase the LED ( / ) flashes.
• No adjustment is necessary.
P03 – Load pressure
• Defines the value of plant pressure, in unload state, that the compressor must to reach to go in a load
phase. In the load phase the LED ( / ) is permanently lit.
• No adjustment is necessary.
P04 – Offset for pressure transducer calibration
• Compensates for possible reading error (either by excess or by defect) of the pressure.
• No adjustment is necessary.
P05 - Max probe temperature
• Provides the highest value for oil temperature probe reading.
• No adjustment is necessary.
P06 - High oil temperature alarm threshold
• Defines the high oil temperature alarm value. As soon as this value is reached, a dedicated alarm message
(A01) appears on the display and the compressors is blocked.
P07 - High oil temperature pre-alarm threshold
• Defines the high oil temperature pre-alarm value. As soon as this value is reached, the compressor stops
and a dedicated alarm message (a03) appears on the display, but the normal operation of the compressor
is not interrupted.
P08 - Low oil temperature alarm threshold
• Defines the low oil temperature alarm value. Under this value, compressor start-up is inhibited and a
dedicated alarm message (A34) appears on the display.
P09- Offset for oil temperature probe calibration
• Compensates for possible reading errors (either by excess or by defect) of the temperature probe due to a
defective probe.
• In normal conditions, this parameter needs no adjustment.
