4.5.3. MCS 4

Fig. 4.16: The BOGE Master Control System 4
MCS 4 controls a maximum of 4 or 8 compressors of the same and/or different sizes and types in a system. All compressors are controlled by a common pressure sensor at the compressed air receiver.

The basic load with this control unit is normally covered by the largest compressor or combination of compressors. The smallest compressor takes the peak load. Compressors of the same size change over in providing the basic load.

The MCS 4 computes compressed air consumption continually from programmed compressor performance data and information from the pressure sensor. It selects the compressor that most closely matches the requirement.<BR><BR>

The control offers:
    • need-oriented use of the various compressors and compressor combinations.
    • ideal use of the benefits of screw and piston compressors.
    • minimal cut-in difference of 0.5 bar.
      ( no over-compression ? energy-saving )
    • three different pressure profiles per day by a timer programme to adapt the control to differing compressed air requirement.
    • Time adjusted use of compressors on demand by the control unit.
    • Well-organised LCD-display with 2 x 20 characters and clear text output.
    • Possibility to check all inlets and outlets via a test menu.
    • Automatic switchover to pressure switches in the event of voltage loss.
    • The individual compressors operate independently without the MCS 4. They are then controlled by their own pressure switches.
    • Two potential-free timer contacts for control of additional components.
