3.3. Operating conditions
The product works properly only if the followings
conditions are respected.
- Floating voltage rate: +/-2% max
- Floating frequency rate: 50-60 Hz +/-2%
- Ambient temperature: -10°C a +50°C
- Relative Humidity: from 20 to 90% without
condensing
- Vibration: max 16,7 m/s2 (2 g) at 10-55Hz
- Altitude: Below 1000 m inside a building.
- Galvanic isolation (I/O feeds according to
PELV)
The current of the frequency converter must be
equal or greater than the maximum current that the
motor of the pump could absorb.
The system is made of:
Frequency converter
Transducer (pressure/temperature/ow are
possible)
Mounting Screws
Motor Adapter Kit
3.4. Product overview
I-MAT is a frequency converter for pumps, that
implements the followings operating modes:
Constant pressure;
Proportional pressure;
Constant temperature;
Constant ow;
Night mode;
Fixed speed;
Constant pressure mode and Proportional pressure
mode are available also in cascade mode.
3.5. Pushbuttons functions
The user interface is made by a 6 pushbuttons
keyboard. Every pushbutton has a specic function
described in the following table.
Through this button you can start the
pump.
Through this button you can stop the
pump
