Inverter for electric pump control

• Electronic device for the electric pumps control based on inverter technology.
• It controls the starting and stopping of the electric pump and modulates the motor rotations according to the water request from the system.
• Constant pressure due to motor pump speed regulation.
• Energy saving due to less pump absorption.
• Gradual pump start and stop reduces hammering and avoids breakaway starting current.
• Protection against dry running in event of water shortage on the suction.
• Automatic reset in event of dry running, with autonomous error condition recovery.
• Efficient leakage monitoring to protect pump in event of repeated restarts.
• Digital pressure display.
• Motor over current control.
• Operation/error status signalling via LEDs and on-screen alerts.
• Operation in master/slave confi guration into twin booster sets.
• Double set point with remote control option.
• Remote start and stop of electric pump.
• Rotation direction inversion via software (it does not require wiring alterations).
• Extractable terminals to facilitate wiring.
SIRIO is an electronic device designed to automatize start and stop operations of an electric pump based on frekvency regulation. When the pressure drops or the flow in pipeline interrupts-opening and closing of the taps respectively-SIRIO manages automaticallly start and stop operations of the pump. Furthermore SIRIO handles the impotrant operation of stop for dry running, switching the pump off in case of lack of water, protecting it from dangerous dry running.
