1 Defines the opening time of the load
relief solenoid valves N.A. of the step in closing
duration phase. This parameter is fundamental
to let the pressurized water inside the
collectors and avoid dripping problems.

Manages the logic of the FLUX-
input logic G0A contact which verifies
the air passage in the duct.
The possible logics are the
following:
N.C. signifies that there is an air
passage in the duct
N.A. signifies that there is no air
passage in the duct

pressure mode and if all the
steps have been dimensioned
with the same capacity
2 Time
Time after which the rotation
is performed from one step
to another
Rack temperature probe
It is possible to install a temperature probe immediately before the
distribution system in order to verify if the temperature is optimum for
the proper absorption of the atomized water.
