Download PDFWater-cooled frequency converter with integrated pressure and flow monitor for pump speed control. The inverter controls and monitors a constant, preset pressure level. Designed for use with clean, non-aggressive water.
If the pressure in the system drops by a preset difference in pressure values compared to the set pressure, the MM9 inverter switches on the pump . When the pump returns to the set pressure value, the inverter switches it off after a certain time interval.
The inverter also provides the pump with protection against dry running , overcurrent, frost, short circuit, overvoltage and undervoltage and too high a temperature of the pumped water. Control and adjustment is performed via the LCD display using the buttons. The inverter is installed between the pump and a pressure diaphragm vessel with a minimum volume of 2 l. It is necessary to install a non-return valve on the connection to the pump in front of the inverter.
