FUNKTIONAL DESCRIPTION
air
telligence PROVIScombines 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,
air
telligence PROVIS 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
air
telligence PROVIS 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,
air
telligence PROVIS 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
air
telligence PROVIS 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.
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.
