Description
The ECO-NET 128 control unit (Master Economiser) is an electronic device for controlling
pneumatic cleaning of the Industrial Dust Collector Systems. Thanks to the digital control of the
pressure differential, carried out by the internal transducer, the Eco-Net 128 accurately analyses the
status of clogging of the filters and automatically manages cleaning only when necessary; thus
optimising the entire dust removal process.
The construction technology of the Eco-net 128 allows up to 127 valve actuators to be connected in
cascade mode, via 3-wire Bus communication.
The control unit has a powerful micro-controller which, through innovative software, makes the
instrument easy to use even by inexperienced users.
The Eco-net 128 has a graphic LCD with menu in 5 languages, through which the user can control
the entire cleaning process and make settings by accessing the various menus via a series of
buttons positioned on the front panel of the control unit.
The following are available on the control unit connection terminal board:
-2 digital inputs for remote control (Remote control, fan status);
-2 alarm relays (actuators anomaly, Δp pressure exceeded);
-1 current-Loop 4÷20mA output for pressure Δp re-transmission;
-1 output for valve actuators Bus connection;
-1 current-Loop 4÷20mA input (optional);
Other control unit features are:
-Backlit display with menu in five languages;
-Operating mode can be selected from “manual”, “automatic”, “proportional” and “special”;
-Pressure unit of measurement can be selected from KPa, mBar, mmH2O, Inch WC;
-Extended power supply voltage range (100÷240Vac 50-60Hz) (optional: 24Vac/24Vdc);
-Fan off washing function (Post pul.) using the fan ∆p threshold in setting automatic/proportional mode and by means of
external contact in manual/special mode with programmable number of cycles;
-Hour Meter and Pulse Counter for maintenance;
-Minimum ∆p alarm (broken hose) with on/off selection.
-Maximum ∆p alarm (clogged filter);
-Valve actuator not working alarm;
-Filtering elements maintenance alarm, with on/off selection.
-Cleaning cycle start from external contact.
-Compressed air presence consent input.
-Precoating Function;
-Manual activation of individual valve actuator for system test function:

The cable used for wiring must be of the following type: H05VV-F 0.75mm2–19AWG.
The cable connected to the P11 connector of the Eco-Net 128 control unit, must be introduced into the
“IN” port of the first valve actuator present on the chain, using a PG7 type connector, complete with
seals supplied, to guarantee the IP sealing of the circuit.
Successively, jumpered wiring must be realised from the “OUT” port of the first actuator, for connection
to the “IN” port of the next valve actuator, using the same measures illustrated above.
Repeat the same operation up to the last valve actuator of the bus. A PG7 closing connector must be
mounted on the “OUT” port of the last actuator, without cables but with the rubber cap supplied.
Below find a typical actuators Bus connection layout:
To realise the connection cable for the "IN" and "OUT" ports of
the valve actuators, the indications must be followed:

Connection layout to the ERCP pilot enclosure boxes
Connect the 3-wire cable coming from the IN connector of the first pilot enclosure box for pneumatic
drive (ERCP) present in the system, to the P11 connector of the Econet control unit, as shown in the
following layout:
Key:
1
Remote pneumatic valve
2
Connection pipe between remote pilot and the valve
3
Enclosure with built-in pilots for driving valves
4
Connection cabling between the ERCP pilot enclosure boxes
5
Connection cabling between the control unit and the pilots
enclosure box
Several pilots enclosure boxes are present in the system; connect them in
sequence in a way that the OUT connector of an ERCP pilots enclosure
box is connected to the IN connector of the next ERCP pilots enclosure
box.
Use a connection cable made with a DIN 43650 connector, to fix onto a
cylindrical base, making sure that the relative IP sealing gaskets are
mounted.
Complete installation by hermetically closing the OUT connector of the
last ERCP pilots enclosure box present in the system.
