Abstract

Uses a microcontroller with motor (M1) timer inactivation (13/1) which operates when the motor is connected to the voltage supply after the longest elapsed time set by the timer. The device (13/1) also deactivates the timer following at least 4 times in which a timer substractor has not started an intermediate action. Motor/pump group (1) including a pump (P1) driven by an electric motor (M1) controlled by a microcontroller (E1) integrated in the group (1). The microcontroller connects the motor to the voltage supply when it receives a signal from a fluid level sensor (CN1) and disconnects the voltage supply when it receives a signal from a stop sensor (CA1). The microcontroller includes a timer (13/1) designed to delay the application of supply voltage to the motor for a time duration randomly chosen from amongst progressive increasing time steps. A time decrement (D1) is designed to reduce the timed step for each signal received from a liquid level sensor (CN1) during which the voltage supply is not applied to the motor.
