    DETAILED DESCRIPTION

    LVMP30A..

    General characteristic

    The LVMP30... priority change relays manage the alternation between 3 or 4 motors, with the purpose of making homogeneous operating time and wear. They are typically used in pumping systems where there may be 3 or 4 pumps to be controlled alternately. The presence of the keyboard with display allows to set up the system configuration quickly and easily, by selecting the number of motors to control, the setting of motor switch-on and switch-off delays, and to monitor the number of starting and the operating hours for each motor.
