 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 ).
