ON I OFF (0/100)
: On-off compressor that uses only one digital output (relay) to drive it.
0 I 50 I 100:
Compressor that uses two digital outputs (relay) to drive it, the main output and an auxiliary output, where each output corresponds to 50% of
the compressor capacity.
0 I 33 I 66 I 100:
Compressor that uses three digital outputs (relay) to drive it, the main output and two auxiliary outputs, where each output corresponds
to 33% of the compressor capacity.
0 I 50 I 75 I 100:
Compressor that uses three digital outputs (relay) to drive it. The main output corresponds to 50% of the compressor capacity and each
of the two auxiliary outputs corresponds to 25% of the compressor capacity.
0 I 25 I 50 I 75 I 100:
Compressor that uses four digital outputs (relay) to drive it. The main output corresponds to 25% of the compressor capacity and
each of the three auxiliary outputs corresponds to 25% of the compressor capacity.
Inverter (Proportional):
Compressor that uses an analog output (0-10 V) for its control (available for compressor 01 of each suction). Optionally it is
possible to configure a digital output with Start-stop function, in parameter
1.2.x.35
a “compressor 1 main output”.

1.2.x.33
Activation mode of compressor 01-06:
Parameter that determines the output activation preference for compressors using auxiliary digital outputs. For more information on unloader activation
modes (auxiliary outputs), see section: 14.2 Compressor modulation:
1.2.x.34
Compressor 01 analog output:
Address of compressor 01 analog output. This parameter is available when compressor modulation is Inverter (Proportional).

Compressor 01-06 principal output:
Address of the digital output of compressor xx.
1.2.x.36, 40, 44, 48 , 52, 56
Compressor 01-06 auxiliary output 1:
Address of the auxiliary output 01 of compressor xx.
1.2.x.37, 41, 45, 49, 53, 57
Compressor 01-06 auxiliary output 2:
Address of the auxiliary output 02 of compressor xx.
1.2.x.38, 42, 46, 50, 54, 58
Compressor 01-06 auxiliary output 3:
Address of the auxiliary output 03 of compressor xx.
1.2.x.59
Minimum time between compressor activations:
The function applies to the main control outputs of the compressors and is the minimum time between two activations of the main digital outputs. This
time ensures that no simultaneous compressor activations will occur, preventing surges in the power network and excessive fluctuations in the control
pressure
.
1.2.x.60
Minimum time between compressor deactivations:
The function applies to the main control outputs of the compressors and is the minimum time between two deactivations of the main digital outputs. This
time ensures that no simultaneous compressor deactivations will occur, preventing variations in the power network and excessive fluctuations in the
control pressure.
1.2.x.61
Minimum compressor on time:
It is the minimum time for which the compressor remains switched on, i.e. the length of time between the last start up and the next stop.
1.2.x.62
Minimum compressor off time:
It is the minimum time for which the compressor remains switched off, i.e. the length of time between the last stop and the next start up.
1.2.x.63
Time between unloader activations:
It is the time between activations of two auxiliary digital outputs (unloaders) of the same compressor.
Example:
A compressor with 0 | 33 | 66 | 100 modulation uses one main output and two auxiliary outputs. The time between activations of the two
auxiliary outputs (66% and 100%) must be greater than the time between activations of the unloaders.
