Inverter configuration
For each inverter used in the plant must be selected also the related digital output position for the
command/consent at the inverter start; For the configuration the same parameters of the compressor digital
outputs are used, parameters HC01, HC02, HC03, HC04. The inverter is virtually the first compressor of each
circuit; this means that, depending of the compressors and circuits number, the right parameter must be set, by
following below logic:
⋅
Signle Circuit: The inverter (if enabled) is virtually the compressor 1; it is neccessary to configure the
parameter of the first compressor, this means that parameter HC01 must be always configured.
⋅
Two circuits: The inverter of circuit 1 (if enabled) is virtually the compressor 1 (this means that
parameter HC01 must be configured), and the circuit 2 inverter (if enabled) is virtually the first
compressor after the circuit 1 compressors.
Note. The PH20 parameter modifies the logic for the inverter consent (managed by relay or by PWM).
Configuration examples.
1) N°1 Circuit (PG01=1), n°2 Compressors (PG11=2), Inverter enabled (PG12=1). A correct configuration is:
HC01 = 1 -> Digital output for the inverter consent
HC02 = 2 -> Digital output for the hermetic compressor command
HC31 = 1 -> Analog output for the inverter command
2) N°2 Circuits (PG01=2), n°2 Compressors for each circuit (PG11=2, PG15=2), Inverters enabled (PG12=1,
PG16=1). A correct configuration is:
HC01 = 1 -> Digital output for the circuit 1 inverter consent
HC02 = 2 -> Digital output for the circuit 1 hermetic compressor command
HC03 = 3 -> Digital output for the circuit 2 inverter consent
HC04 = 4 -> Digital output for the circuit 2 hermetic compressor command
HC31 = 1 -> Analog output for the circuit 1 inverter command
HC32 = 2 -> Analog output for the circuit 2 inverter command
3) N°2 Circuits (PG01=2), n°1 Circuit 1 compressor, n°2 Circuit 2 compressors (PG11=1, PG15=3), Only
circuit 2 inverter enabled (PG12=0, PG16=1). A correct configuration is:
HC01 = 1 -> Digital output for the circuit 1 first hermetic compressor command
HC02 = 2 -> Digital output for the circuit 2 inverter consent
HC03 = 3 -> Digital output for the circuit 2 first hermetic compressor command
HC04 = 4 -> Digital output for the circuit 2 second hermetic compressor command
HC31 = 1 -> Analog output dor the circuit 1 inverter command
HC32 = 2 -> Analog output dor the circuit 2 inverter command
4) N°2 Circuits (PG01=2), n°1 Circuit 1 compressor, n°3 Circuit 2 compressors (PG11=1, PG15=3), Inverters
enabled (PG12=1, PG16=1). A correct configuration is:
HC01 = 1 -> Digital output for the circuit 1 inverter consent
HC02 = 2 -> Digital output for the circuit 2 inverter consent
HC03 = 3 -> Digital output for the circuit 2 first hermetic compressor command
HC04 = 4 -> Digital output for the circuit 2 second hermetic compressor command
HC31 = 1 -> Analog output dor the circuit 1 inverter command
HC32 = 2 -> Analog output dor the circuit 2 inverter command
