7. INVERTER ELECTRONIC CONTROL AND USER INTERFACE

The inverter makes the system work at constant pressure. This regulation is appreciated if the hydraulic plant downstream from the
system is suitably sized. Plants made with pipes with too small a section introduce load losses that the equipment cannot compensate;
the result is that the pressure is constant on the sensors but not on the utility.
Plants that are excessively deformable can create the onset of oscillations; if this occurs, the problem can be solved by adjusting the
control parameters "GP" and "GI" (see par. 9.6 - GP: : Proportional gain coefficient and 9.6 - GI: Integral gain coefficient).

7.1 Operation with control unit

E.sybox, alone or in a pumping unit, may be connected by means of wireless communication to a remote unit referred to below as a control unit.
Depending on the model, the control unit offers a variety of functions.
The possible control units are: e.sylink.
Combining one or more e.syboxes with a control unit allows the use of:
– Digital inputs
– Relay outputs
– Remote pressure sensor
– Ethernet network connection
Below, the combination of functions listed above, made available by the various types of control unit, will be referred to as "control unit functions.

7.1.1 Functions made available by control units

The functions made available are specified in Table 6 Functions made available by control units.
Functions
Opto-isolated digital inputs
Output relay with NO contact
Remote pressure sensor

7.1.2 Electrical connections of utility inputs and outputs

See control unit manual.

7.1.3 Safety mode operation

When using the input or remote sensor functions, in the event of a communications downage or control unit error, the e.sysbox and control unit
will switch to safety mode, adopting the configuration considered least damaging. When safety mode comes into operation, a flashing icon showing
a cross inside a triangle appears on the display.
The way in which the e.sysbox responds to a communications downage is explained in the table below.
