Variable speed system driven by frequency converter Construction Variable speed system driven by frequency converter, for the pressure control in domestic and residential plants. The system is connected to the delivery pipe providing for simple installation and better cooling (patented) making the unit more compact and easy to assemble. Easymat is supplied with one pressure transducer, G 1/4 connection and 1.5 m cable length. Applications Automatic frequency inverter control for use on pumps to increase network pressure. The system maintains constant pressure whilst the controlling the pump operation against changing system demand. For protection of the pumps: – Against dry running – Against operations with closed connection ports – Against overcurrent of the motor – Against overvoltage and undervoltage of the power supply Operating conditions Features Constant pressure The Easymat via a frequency inverter keeps the pressure constant as the flow demand changes. EASYMAT MM - Input voltage: 1~ 230V ±10% - Output voltage: 1~ 230V EASYMAT MT - Input voltage: 1~ 230V ±10% - Output voltage: 3~ 230V Input frequency: 50-60 Hz Output frequency: up to 70 Hz Protection: IP 55 Max Ambient temperature: 40°C Max liquid temperature: 40 °C (50°C for 5MM, 5,5MT) Minimum Flow: 3 l/min Altitude: no higher than 1000 m, inside a closed environment. Construction Energy saving The variable speed operation ensures that only the energy required by the plant at any instant is used. System reliability Because the easymat is independent of the pumped liquid it's operation is not affected by fluid impurity. A float switch can also be integrated to further protect against dry running. (Standard execution) The system comprises of: - Frequency converter. - Pressure transducer. - Pipe housing. - Fixing screws. - Terminal board. - Cable glands. - Multi-hole gaskets. Type Flexibility Thanks to it's patented design the easymat does not come into contact with the pumped fluid. This provides for more flexibility during installation eliminating the need for pipe-work modifications or the installation of isolating valves. Type (single-phase) Freqeuency converter max current output Standard power motor 230V Freqeuency converter max current output Standard power motor 230V Easymat 5MM Easymat 9,2MM Easy to use The easymat has a clear display making it very simple to set-up. Type (three-phase) Cascade control mode The system flexibility allows via a microprocessor for cascade operation of two easymat's via one pressure transducer.

Variable speed system driven by frequency converter Control Panel Easymat is equipped with a control panel for simple system programming and parameter monitoring. The 2 scroll buttons are used to scroll the different operating parameters that EASYMAT can show. At the same time you can use the 2 scroll buttons to move in the set up menu and to change the different options. The LCD custom display gives an easy overview of the system situation and of the operating parameters. The icons on the top and below the display area explain in which way EASYMAT is working and if there are problems on...

Variable speed system driven by frequency converter Installation example One pump installation scheme Two pumps installation scheme Three pumps installation scheme Plant conversion scheme Existing fixed speed version With EASYMAT it is easy to create a variable speed system starting from a existing fixed speed system without disturbing the existing pipe-work. To create the variable speed system it is only necessary to: - Disconnect the pressure switch from the system and, in the same housing connect the pressure transducer. - Connect EASYMAT to the pipe. - Connect EASYMAT to electric motor....
