17.2 Probe configuration
Probes can be used in different ways according to plant features, as described in the following
table:
Suction probe configuration
P1c Suction probe setting (probe 1):
nP = not used: don’t set it;
Cur = 4 – 20 mA pressure transducer; use term. 6 (+), 5 (in); 10 (gnd) if present
tEn = 0.5 - 4.5 V ratiometric pressure transducer; use term. 4 (+), 5 (in); 10 (gnd)
ntc = NTC 10K probe; use term. 4 - 5
PA04 Adjustment of read out for the Probe 1 (used only if Pbc=Cur or tEn). Corresponding
to 4 mA or 0.5 V input signal, given by the suction probe (-1.0 - PA20 bar; -15 - PA20 PSI;
-100 - PA20 kPA)
E.I. PP11 relative pressure transducer, range -0.5 - 11.0 bar. PA04 = -0.5; PA20 = 11.0
PP30 relative pressure transducer, range: 0 – 30 bar, PA04 = 0.0; PA20 = 30.0.
PA20 Adjustment of read out for the Probe 1 corresponding to 20 mA or 4.5 V input signal,
given by the suction probe (PA04 - 51.0 bar; PA04 – 750 PSI; PA04 – 5100 kPA).
CAL Probe 1 calibration: the range depends on the dEU parameter:
dEU = bar or °C: -12.0 - 12.0;
dEU = PSI or °F: -20 - 20;
dEU = kPA: -120 - 120;
Condenser probe configuration
P2c Condenser probe setting (probe 2):
nP = not used:
Cur = 4 - 20 mA pressure transducer; use term. 6 (+), 7 (in); 10 (gnd)
tEn = 0.5 -4.5 V ratiometric pressure transducer; use term. 4 (+), 7 (in); 10 (gnd)
ntc = NTC 10 K probe; use term. 4 - 7
FA04 Adjustment of read out for the Probe 2 (used only if Pbc2 = Cur or tEn). corresponding
to 4 mA or 0.5 V input signal, given by the delivery probe
(-1.0 - FA20 bar; -15 - FA20 PSI; -100 - FA20 kPA)
FA20 Adjustment of read out for the Probe 2 corresponding to 20 mA or 4.5 V input signal,
given by the condensing probe (FA04 - 51.0 bar; FA04 – 750 PSI; FA04 – 5100 kPA)
FCAL Probe 2 calibration the range depends on the dEU parameter:
dEU = bar or °C: -12.0 - 12.0;
dEU = PSI or °F: -20 - 20;
dEU = kPA: -120 - 120;
Probe 3 configuration
P3c Probe 3 setting:
nP = not used:
Cur = 4 - 20 mA pressure transducer; use term. 6 (+), 3 (in); 10 (gnd) if present
tEn = 0.5 - 4.5 V ratiometric pressure transducer; use term. 4 (+), 3 (in); 10 (gnd)
10 = NTC 10 K, 86 = NTC 86 K
3P04 Adjustment of read out for the Probe 3 (used only if P3c = Cur or tEn). corresponding
to 4 mA or 0.5 V input signal, given by the delivery probe
(-1.0 - 3P20 bar; -15 - 3P20 PSI; -100 - 3P20 kPA)
3P20 Adjustment of read out for the Probe 3 corresponding to 20 mA or 4.5 V input signal,
given by the condensing probe (3P04 - 61.0 bar; 3P04 – 885 PSI; 3P04 – 6100 kPA)
O3 Probe 3 calibration the range depends on the dEU parameter:
dEU = bar or °C: -12.0 - 12.0;
dEU = PSI or °F: -20 - 20;
dEU = kPA: -999 - 999;
