FUNCTIONAL DESCRIPTION
4
AIRLEADER combines compressors of different sizes
to an optimum unit which automatically adapts to the production based on the current compressed air consumption. It is
made sure that it is always the most efficient compressor combination which generates the compressed air necessary for
production, independent of the manufacturer and the performance. The system pressure remains within the smallest
limits. It is seen that the costs are kept as low as possible. The compressor performances and a common pressure
difference are programmed in for all the compressors. Based on this information, AIRLEADER permanently calculates the
current compressed air consumption and the volume of the compressed air system. The self-learning 8-fold calculation
depth makes it possible to adapt the compressors to the changes in consumption in a dynamic way.
Automatic compressor change as per compressed air consumption
If all the compressors are on the same rank, they are working fully automatically and based on real air consumption. The
priority of the compressors is adapted to the production process in real time with a useful hysterisis calculation. It is always
the compressor combination with the lowest cycle rates which is running and thus with the lowest idle times. Big
compressors are only running when needed. The smaller compressors are running under load instead of idling the big
compressors. The compressors auto-regulate the motor start limitations.
The status of the compressors is constantly monitored.
If a running compressor displays a malfunction within the pressure range or is switched off for service, its performance is
taken over by other compressors. If several compressors are needed to do this, addition is made time-delayed. Load and
total running times are stored for the individual compressors. The operating hours are deleted, if required.
Connecting of compressors
is effected using the connecting moduls this being installed in the electrical housing of the compressor on the DIN-rail. The
connection to the Master control is made over the industry us RS 485 bus. The operating voltage of 24 volts AC/DC can
be attached to the tension supply of the compressor. If a power supply of 24V AC or DC is available from the
compressor electric.
Compressor fault
If a compressor goes on fault the display shows a symbolic cross. On fault of reported compressor the performance gets
the compressed air consumption the most favorable compressors combination replaces through this one. The fault report
for the compressors is activated at the AIRLEADER an common fault signal.
Faults from the connection modules will be given out over the digital output „General fault of external equipment.
Compressor motor running
If these inputs get connected, AIRLEADER receives the motor running time. The total hours are also stored as the load
hours. The advertisement of the hours can be retrieved over the display. The running time compensation provides equally
running times of compressors with same capacity.
Compressor ready input
These input must be connected so that compressor management AIRLEADER recognizes the readiness of the
compressors. If these input don't get connected, the compressor cannot be in operation. A fault signal isn't activated.
der Kompressor nicht bereit und kann nicht angewählt werden. Eine Störmeldung wird nicht aktiviert.
If the fault input is not connected
and one of the compressors stops due to a malfunction, the display will show a wrong compressed air consumption (too
high = by the value of the faulty compressor). For this reason it is advisable to connect the malfunction signal inputs, so
that the compressed air consumption is always shown correctly and the capacity is also corrected and immediately after
reaching the P min.
