5. FUNCTIONS
If the settings made during commissioning are not sufficient to achieve the desired operation, further (detailed) configuration
of the parameters can be performed, as described in the following paragraphs.
The parameters described below can be configured via the configuration software or the “APPLICA” app.
Caution:
the information available in Applica may vary according to the password set and the configuration defined by the
unit manufacturer, and consequently not all of the parameters shown may be visible or modifiable.
For details on the parameters and the related access levels, see the “Parameter table”.
5.1 Inputs and outputs
The MPXone Advanced version features up to 8 analogue inputs and 5 digital inputs. See the description of the terminals in
“Description of the terminals”.
The probes (temperature NTC, PT1000, 0.5-4.5 Vdc ratiometric and active probes), can be connected to the analogue inputs, and
have been divided into 4 groups, with the same type of probe for each group. See the parameter table.

Caution:
for the maximum current that can be supplied to the ratiometric probes, see the technical specifications table.
Inputs S4, S5 and S6 can be connected to 0.5-4.5 V ratiometric pressure probes (CAREL standard ratiometric) and active probes
with 4-20 mA or 0-10 V output (S6 only). All these probes require the range of measurement to be defined, set by the relative
minimum and maximum parameters for the function associated with the probe. The same applies to input S7 for ratiometric
probes. See the parameter table.
To assign the function to each physical or serial probe, configure parameters /FA, /Fb, ... /Fn. See the parameter table.
