MA-P4 pulsation control is based on a powerful microprocessor, which allows for the individual programming of the 4 pulsation channels, as well as the frequency, the relationship between front-rear quarters, and the staggering of the channels with each other. All these parameters are programmed from the external keyboard with extreme ease. Any problem, short circuit, or overload in any channel is indicated on the display corresponding to that channel, while simultaneously emitting an acoustic alarm signal. Electronic pulsation control.
