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;
