Analog Inputs
CF 7
Pressure or temperature analogue input functioning
0 = Temperature / pressure NTC – 4÷20 mA :
The condensing temperature is controlled with NTC probe while for the
evaporating pressures of the circuits 1 and 2 and the pressure probe configured
as auxiliary output 1 and 2 are controlled with 4÷20mA transducers.
1 = Pressure control with 4÷20 mA:
To control the evaporating and condensing pressures it is necessary a 4÷20mA
transducer.
2 = Temperature / pressure NTC – 0÷5Vdc:
The condensing temperature is controlled with NTC probe while for the
evaporating pressures of the circuits 1 and 2 and the pressure probe configured
as auxiliary output 1 and 2 are controlled with 0÷5Vdc transducers.
3 = Pressure control with 0÷5Vdc:
To control the evaporating and condensing pressures it is necessary a
ratiometric 0÷5Vdc transducer.
