LEO device for controlling and protecting electric pump against dry running PS-04F 1.8kW 220-240V
FUNCTIONS
Ensuring pressure maintenance (integrated check valve). Built-in check valve to maintain constant pressure in the water supply line after the pump is turned off.
Dry-running protection. Detects lack of water or low pressure, activates dry-running protection and stops the pump.
Automatic start/stop. When the user closes the tap, an electronic sensor detects that there is no flow and the pressure exceeds the initial pressure, the pump is stopped.
The pump starts at pressure (0.5 ÷ 3 bar). Pump starts when the pressure in the inlet pipe drops (The initial pressure value changes depending on the limit pressure setting).
Pump starts at flow in the pipeline. The pump starts when water flows in the pipe.
Self-reset/dry-running protection. When the pump is protected against dry running, the pump attempts to start every 15 minutes, and starts when water is available for its normal operation.
Anti-blocking/anti-jamming function. The pump starts once every 24 hours under pressure, maintaining the shutdown function (10 s).
Pressure limiting function. Adjust and limit the outlet pressure to prevent pipeline damage due to excessive pressure, reduce the pressure to ensure proper water supply and improve comfort of use.
