4.3.1. Intermittent control


<BR>
Fig. 4.1: Op. diagram of cutout control
    With intermittent control a pressure switch or contact manometer actuates the compressor, depending on network pressure.

    The compressor has two operating modes, Operating mode ( L 2 ) and Stopped ( L 0 ).

    This arrangement has the best energy consumption of all types of control. It is recommended when there is a large compressed air receiver. A large storage volume also reduces the number of motor cycles.
      • The network pressure p N rises to the cut-out pressure p max.
        The compressor switches to
        Stopped ( L 0 ).
      • The network pressure p N drops to cut-in pressure p min .
        The compressor switches Operating mode ( L 2 ).
