4.5.4. MCS 5

Fig. 4.18: The BOGE Master Control System 5
MCS 5 controls a maximum of 4, 8, or 12 compressors with infinite output control of the same and/or different size and construction in a system. All compressors are controlled by a common pressure sensor on the compressed air receiver. The peak load compressor controls accordingly the requirement of compressed air via its infinite output control.

If the compressed air demand drops this compressor switches off and the medium load compressor takes over via its infinite output control, depending on the level of priority.

Up to their use of infinite control the MCS 3 and MCS 5 are similar. <BR><BR>

The control unit offers:
    • Adaptation of FAD to the compressed air demand by infinite output control by the peak load compressor.
    • Minimal pressure fluctuations in the pneumatic network.
    • Dynamic pressure control by microcontroller in conjunction with the electronic pressure control for a minimum cut-in difference of 0.5 bar. ( no over-compression ? energy savings )
    • Time-independent allocation of compressors in level of priority for shift operation with differing compressed air demand.
    • Individual allocation of compressors in the load range groups with even usage of compressors.
    • Adjustable basic load change cycle.
    • Independent rotation of compressors in the load range groups.
    • Time adjusted use of compressors on demand by the control unit.
    • Well arranged LCD-display with 4 x 20 characters and clear text output.
    • Possibility to check all inlets and outlets via a test menu.
    • Automatic change to pressure switches of individual compressors in the event of voltage loss.
    • The individual compressors operate independently without the MCS 5. They are then controlled by their own pressure switches.
