6.1.20 Analog Output 3 (3Q2-3Q26)
3Q2 Analog output 3 function (term. 31-32)
FREE = pure analogue output
CPR = output for inverter frequency compressor – circuit 1
CPR2 = output for inverter frequency compressor – circuit 2
FAN = output for inverter fans – circuit 1 (only some fans driven by inverter, others enabled by on/off);
FAN2 = output for inverter fans – circuit 2 (only some fans driven by inverter, others enabled by
on/off);
INVF1 = proportional inverter for fans of circuit 1 (all fans driven by inverter)
INVF2 = proportional inverter for fans of circuit 2 (all fans driven by inverter)
nu = not used
3Q3 Reference probe for analogue output 3, it's used only when 3Q2 = FREE
Pbc1= Suction Probe, circuit 1 (term. 62-63 or 62 -68)
Pbc2 = Suction Probe, circuit 2 (term. 64-63 or 64 -68)
3Q4 Adjustment of read out for the analog output 3 (-1.00÷100.00 bar; -15÷750PSI; -50÷150°C; -
58÷302°F; -100÷10000 KPA). It's used only when 3Q2 = FREE
3Q5 Adjustment of read out for the analog output 3 at 20mA/10V (-1.00÷100.00 bar; -15÷750PSI; -
50÷150°C; -58÷302°F; -100÷10000 KPA). It's used only when 3Q2 = FREE
3Q6 Minimum value for analogue output 3 (0 ÷ 100%)
3Q7 Analog output 3 value after load start (3Q6 ÷ 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
3Q8 Analog output 3 value after a load is switched off (3Q6 ÷ 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
3Q9 Exclusion band start value for analog output 3 (3Q6 ÷ 100 %): it allows to exclude a range of
frequencies that could create problems to the compressor. – Used during inverter regulation
3Q10 Exclusion band end value for analog output 3 (3Q9 ÷ 100 %) – Used during inverter regulation
3Q11 Safety value for analog output 3
3Q12 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 inverter starts dued to pressure variations. – Used during inverter
regulation.
3Q13 Analog output 3 rise time (0 ÷ 255 sec). It's the time necessary to the analog output to pass from
the 3Q6 to 100%, when a compressor has started and the pressure/temperature is above the
regulation band. – Used during inverter regulation.
3Q14 Analog output 3 permanency at 100% 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
3Q15 Delay between pressure (temperature) goes down the set point and start of analog output 3
decreasing (0÷255sec). – Used during inverter regulation
3Q16 Analog output decreasing time (0 ÷ 255sec) It's the time taken from the analog output to pass from
100% to the 3Q8 value. It's used during the switching off phase, when the pressure is below the set
point.
3Q17 Analog output 3 permanency at 3Q6 before a load is switched off (0 ÷ 255sec) When the
pressure (temperature) is belove the set point, the analog output 3 remains at 3Q6 value for the
3Q17 before a load is switched off.
3Q18 Analog output 3 decreasing time when a load is switched on (0 ÷ 255sec) It's the time necessary
to the analog output to pass from 100% to 3Q7 when a load is switched on.
3Q19 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 + 3Q19.
3Q20 Integral time (0÷999s; with 0 integral action excluded). It sets the pound of the proportional action.
The higher is 3Q20, the lower is the integral action support.
3Q21 Band offset (-12.0÷12.0°C -12.00 ÷ 12.00BAR, -120÷120°F, -120÷120PSI; -1200÷1200KPA). Used
to move the regulation band across to the set point.
3Q22 Integral action limitation (0.0÷99.0 °C; 0÷180°F; 0.00÷50,00bar; 0÷725PSI; 0÷5000kPA) to stop the
increasing of integral action when the pressure reaches the SET + 3Q22 value.
