The P.H2E Complete Solution completely protects itself against lack of water in the well or tank, without the aid of other equipment (probes, cables, sensors, control panels, etc.). In case of dry running, the pump automatically stops, to restart after a programmed cycle time.
The P.H2E Complete Solution is automatically protected against motor overheating. This can happen because of: the high temperature of the pumped liquid; when the minimum distance between the pump installed and the well bottom isn’ t respected; when the pump is installed in well/tanks bigger than 4” without a proper cooling system; when the pump works in shut-off. In such cases, the thermal protection system stops the pump, which automatically restarts as soon as the correct working temperature parameters are restored.
The P.H2E Complete Solution is completely protected against overload. In case the pump is partially or totally blocked, the H2E software, after some automatic restart attempts, makes the pump enter the stand-by mode.
The P.H2E Complete Solution is protected against low or high voltage, that can damage the motor. Low voltage can occur, for example, if the section of the power cable is not adequate considering the motor power and the distance between the plug and the pump itself; or if a generator is faulty or undersized for the pump. High voltage can occur with unstable supply network or with a faulty generator. In these situations, in order to avoid potential damages, the pump stops running. A number of consecutive automatic attempts verifies if the operating parameters are correct; if they are not, the pump enters stand-by mode.
The P.H2E Complete Solution is automatically protected against leaks in the piping system (also when the pressure tank is exhausted or its membrane is defective, or when there is a defective pressure switch) and too frequent starts and stops (for example if the tank is of the incorrect size). In these cases, the pump automatically enters the stand-by mode.
An electronic “soft start” reduces power consumption at the start of the pump. It will avoid annoying drops in power i.e.: flickering lights. Thanks to this function, energy will be saved and the pump will be more reliable. This will also extend the pump’ s life. The P.H2E Complete Solution starts and works even in case of tension drops.
SLP device protects the electronic inside the P.H2E Complete Solution against voltage peaks, which can be caused by electric abnormalities in the supply network or by other various electrical interferences. It reduces overvoltage, keeping the correct operating voltage range or it interrupts the power supply in case of very high peaks.
