Italtecnica Nettuno 2.0 Manual De Instrucciones página 28

 DESCRIPTION
Nettuno is an electronic device, employing inverter-based technology, which controls electric pump stopping and
starting functions. Thanks to the particular type of technology used, it can modulate the frequency (Hz) of the
motor's input current to adjust the speed (rpm) according to the water demand by the system. This way, the value of
the pressure reaching the user appliances is maintained constant all the time and the motor's absorption is always
proportional to the actual system requirements, resulting in notable energy savings over time.

FEATURES
 Constant pressure due to electric pump speed regulation
 Energy savings due to less pump absorption
 Gradual pump start and stop reduces hammering
 Protection against dry running in the event of water shortage during intake
 Automatic reset in the event of dry running, with autonomous clearing of error condition
 Efficient leakage monitoring to protect pump in the event of repeated restarts
 Anti-seize function
 Intelligent overload cut-out management for a longer duration of the inverter
 Digital display of pressure, current, voltage and frequency
 Operation/error status signalling via LEDs and on-screen alerts
 Auxiliary inputs and outputs for remote control and status signalling
 Possibility of interfacing more devices as part of the pressurisation units (two to eight)
 PROTECTIONS
 Dry running
 Overpressure
 Power supply under-voltage
 Power supply over-voltage
 Unbalanced load
 Output terminal short circuit
 Amperometric sensor on motor output
 Internal overheating in inverter (ambient temperature and IGBT temperature)
 Significant leakage with continuous motor pump restarts

EMC
This product has been tested according to the standards stated in the EC declaration of conformity in one of the
typical conditions of use, using shielded cables both on input and output (motor cable 15 metres, without auxiliary
connections). However, experience has shown that significant variations in the level of EMC disturbance can occur
when the type and length of cable used is changed, as well as their position, type of motor used etc. If other
equipment is subject to disturbance, contact the manufacturer to assess additional solutions to reduce
electromagnetic disturbance.
