3Q24 Minimum inverter capacity with poor lubrication (0÷99%; with 0 function excluded) If the
frequency compressor works for the 3Q25 time with a frequency (in percentage) equal or lower than
3Q24, it is forsed to work at 100% for the 3Q26 time in order to make the right lubrication.
3Q25 Time of lower inverter time (1÷255min)
3Q26 Time of Inverter at 100% to restore the right lubrication (1÷255min)

4Q3 Adjustment of read out for the analog output 4 at 4mA/0V (-1.00÷100.00 bar; -15÷750PSI; -
50÷150°C; -58÷302°F; -100÷10000 KPA). It’s used only when 4Q1 = FREE
4Q4 Adjustment of read out for the analog output 4 at 20mA/10V (-1.00÷100.00 bar; -15÷750PSI; -
50÷150°C; -58÷302°F; -100÷10000 KPA). It’s used only when 4Q1 = FREE
4Q5 Minimum value for analogue output 4 (0 ÷ 100%)
4Q6 Analog output 4 value after load start (4Q5 ÷ 100 %) It’s the value of the analogue output after a
compressor has started, when the pressure/temperature is above the regulation band. – Used during
inverter regulation
4Q7 Analog output 4 value after load is switched off (4Q5 ÷ 100 %) It’s the value of the analogue
output when a compressor has been switched off and the the pressure/temperature is below the
regulation band. – Used during inverter regulation
4Q8 Exclusion band start value for analog output 4 (4Q5 ÷ 100 %): it allows to exclude a range of
frequencies that could create problems to the compressor. – Used during inverter regulation
4Q9 Exclusion band end value for analog output 4 (4Q8 ÷ 100 %)– Used during inverter regulation
4Q10 Safety value for analog output 4 (0 ÷ 100 %): it’s used in case of probe faulty.
4Q11 Delay between the entrance in the regulation band and the regulation activation (0 ÷ 255sec):
it’s the delay between the entrance in the regulation band of pressure/temperature and the regulation
start. Used to avoid false frequency starts dued to pressure variations. – Used during inverter
regulation.
4Q12 Analog output 4 rise time (0 ÷ 255 sec) It’s the time necessary to the analog output to pass from
the 1Q6 to 100%, when a compressor has started and the pressure/temperature is above the
regulation band. – Used during inverter regulation.
4Q13 Analog output 4 permanency before load activation (0 ÷ 255 sec): the analog output remains at
100% value for this time before a load is activated. - Used during inverter regulation
4Q14 Delay between pressure (temperature) goes down the set point and start of analog output 4
decreasing (0÷255sec). – Used during inverter regulation
4Q15 Analog output 4 decreasing time ( 0 ÷ 255sec) It’s the time taken from the analog output to pass
from 100% to the 4Q7 value. It’s used during the switching off phase, when the pressure is below the
set point.
4Q16 Analog output 4 permanency at 4Q5 before a load is switched off (0 ÷ 255sec) The analog
output remains at 4Q5 value before a load is switched off.
4Q17 Analog output 4 decreasing time when a load is switched on (0 ÷ 255sec) It’s the time necessary
to the analog output to pass from 100% to 4Q6 when a load is switched on.
4Q18 Regulation band (0.10÷25.00bar; 0.0÷25.0°C; 1÷250 PSI; 1÷250°F;10÷2500 KPA). It is the band
with the proportional action. It replaces CP1 for the inverter regulation. It is add to the set point. The
proportional action starts when the temperature/pressure value is higher than the set point and it
reaches the 100% when the pressure/temperature is equal or higher than set + 4Q18.
4Q19 Integral time (0÷999s; with 0 integral action excluded). It sets the pound of the proportional action.
The higher is 1Q20, the lower is the integral action support.
