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.

Control and interpretation of regulated compressors
6
The various speed regulated compressor is integrated actively
The VSD compressor send the information about the motor speed over an analog output to AIRLEADER. This parameter must be
programmed to the minimal and maximum capacity of the delivered compressed air. The analog output of the VSD
compressor have to be 4-20 mA. VSD Compressors with an analog output of 0-10 VDC must be changed from 0-10 VDC with a re-
ceiving multicoupler to 4-20 mA.
The pressure Setpoint of the VSD compressor must be centrically programmed between the AIRLEADER switch points.
The right combination of compressor capacities
together with speed regulated and normal compressors with a firm performance is decisive for good results in regulation. Is the various
speed regulated compressor the smallest in combination with only bigger compressors there are only small section regulated by the vari-
ous speed compressor. Big mechanical hurdle cannot be regulated directly.

Configuration of regulation range and regulation buffer
7
Examble with a VSD Compresor with a regaulation range between 2,5 - 16 m³/min -
The free definable regulation range max
switches load/unload compressors ON and OFF within the pressure settings of AIRLEADER. The regulation limits are defined with the
regulation range max and the regulation buffer. Is the regulation range max adjusted lower than the maximum capacity of the VSD, the
regulation range max and the regulation buffer will be activated.
Setting the "regulation range max"
Examble: the regulation range max will be programmed to 15 m of m³/min. If than the compressed air consumption is going higher
than 15 m³/min a time flexible trend calculation watches the compressed air consumption and switches another compressor on (10 m
³/min like example). Within the pressure switch points of AIRLEADER. If the speed's regulated compressor reaches the regulation
range max the second time together with the 10 m ³/min compressor at 25 m ³/min air consumption again, the 10 m ²/min compres-
sor will be replaced with the 20 m ³/min compressor directly.
The 10 m ³/min compressor will be switched on if air consumption reaches the regulation range max of the regulated compressor at 35
m of ³/min together with the 20 m ³/min compressor.
Setting the "regulation buffer"
Examble: the regulation buffer will be programmed to 1,5 m³/min. If the compressed air consumption is getting lower and the regulated
compressor comes to the point "lower than 15 m³/min" together with the 10 and 20 m³/min compressor the regulation buffer of 1,5 m³/
min will be activated. The air consumption get again 1,5 m³/min lower a time flexible trend calculation stops the 10 m³/min compressor
inside the adjusted pressure switch points at the AIRLEADER. The VSD compressor regualtes to the capacity of 13,5 m³/min.
Correct setting of regulation buffer incorrect setting of regulation buffer
Regulation range max = 15,0 m³/min Regulation range max = 15,0 m³/min
Regulation buffer = -1,5 m³/min Regulation buffer = -3,5 m³/min
Min compressor capacity = -2,5 m³/min Min compressor capacity = -2,5 m³/min
Control sum = 11,0 m³/min Control sum = 9,0 m³/min
Note:
- the regulation range max will be activ if the control sum is smaller than the capacity of the load/unload compressor
- the regualtion buffer is active if the controll sum is higher than the capacity of the load/unload compressor
The VSD compressor will be run in his best specific range.

Settings „minimum flow rate“ of variable speed compressor
By setting the minimum capacity in the menu of the speed regulated compressor
can be determined whether or below the minimum delivery amount of a normal
compressor compressor in load / idle to run mode.
Setting the minimum flow rate of 0 m / min causes:
The speed controlled compressor is running in start / stop operation as long as the
consumption of compressed air is from 0 to 2.5 m³ / min.
Setting the minimum flow rate of 2.5 m³ / min causes:
Below 2.5 m³/min compressed air consumption a normall compressor is running in
a load / unload mode. The downshift is receding in consumption with a hysteresis
This mode is only economic if the air station with a small compressor as 2.5 to 4 m /
min is installed in addition
Pressure differences caused by dryers and filters
cause may be between the pressure transmitter
of the controlled compressor, and the master
control rule up to 0.4 bar difference.
A precise control of pressure within very close
limits is not possible. The pressure difference at
the higher level control must be expanded by
the pressure value can be set. This results in a
pressure differential of 0.7 bar.
(More than at a station without a regulated com-
pressor)
With the remote control actual pressure value
ensure that the regulated compressor can be operated in conjunction with the master control in a narrow pressure limit.
The analog output of the connection module, deliver the current actual pressure of AIRLEADER via 4-20 mA.
If the compressor pressure transmitter has an different range, than the output has to be adjusted accordingly.
Examble:
AIRLEADER 0-16 bar = 4-20 mA
Compressor 1-20 bar = 4-20 mA or Compressor -1-15 bar = 4-20 mA
An offset value setting for remote actual pressure
can be programmed via the menu of regulated compressor to the pressure setpoint of the controlled compressor to adjust the pressure
difference.
This is especially important when more than 1 controlled compressor is installed in the compressed air network and the analog values
do not match the individual compressors

ences in pressure of compressed air dryers and filters, the control behavior can influence each other greatly.
The configuration is described on page 4.

- if compressor 1 reach the regualation range max - it changes to compressor 2
- if compressor 2 reach the regualation range max - compressor 1 start again
- if both compressors reach the regulation gange max - one of th load / unload compressor will be started
- the controller decides, dependent of air consumption tha one of the regulated compressor can be switched off
The regulation range max
ensure that regulated compressors are always in the correct specific area. If an varaiable speed compressor delivers more air than the
setting of the regulation range max, the control started a flexible trend calculation to start the next load/unload compressor. Dependent of

If the pressure in the "lower Pmin" field is entered as 0.5 bar, Airleader switches the compressors to manual operation,
when this value is undershot. (Control compressor's with their own control)
If the pressure in the "higher Pmax" field is entered as 0.5 bar, Airleader switches the compressors to manual operation if this va-
lue is exceeded. (Control compressor's their own control)
If the "automated manual mode" function is active, The "MAN" key switch has to be switched to "1" for a few seconds.
Then switch back to "0" to activate automatic operation via Airleader,
Compressors in the rank stage 1will be controlled denpendent on the actual air consumption.
If this is not enough, the compressors of the rank 2 and helps rank 1
ATTENTION: Only compressor on the same rank stage will be controlled automaically by the dependent airconsumption.

Delay time start:
If Airleader is activated via the "Start key switch or real time clock" and the network pressure is lower than the settings of
Pmin value, a compressor is switched on immediately. All other compressors will be switched on individually after the programmed
time. Programmed rank profiles are taken into account. order from large to small.
Security zone below:
If the demand for compressed air suddenly increases and the pressure drops below Pmin, further compressors switch on after
calculating an additional demand. Or small compressors are replaced by compressors with greater capacity.
Security zone high:
If the demand for compressed air drops suddenly down and the pressure rises above Pmax, more compressors will be switched off
after programmed time and calculating a reduced demand.
Or larger compressors are replaced by compressors with smaller capacity.
Delay time below:
This function prevents several compressors from being started when they are not required, becaus compressors start only after
approx. 15-30 seconds producing compressed air. If a compressor was switched on in the below ssecurity zone, the next compressor
will only be switched on after the programmed time has been elapsed.
Delay time high:
If a compressor has been switched off at the high security zone, the next compressor will only be switched off after the progammend
time. Setting information: large receiver volume = longer time, small receiver volume = shorter time
FU average:
The analog output signal from the frequency inverter will be averaged with the programmed time.
The control process becomes more harmonious.
Fixed compressors if possible: (Fixed capacity compressors – if possible)
If several speed-controlled compressors are installed in the compressed air network, in combination with compressors with a fixed
output, these will be switched on as early as possible in order to increase the specific power.
The prerequisite for this is a sufficient large regulation range of variable speed compressors.
FU Control: See page 11
This function can be activated when several variable speed compressors are working in the same compressed air network.
The condition here is that the variable speed compressors get the net pressure via the analog output of the compressor module
according to the network pressure. (ACTUAL pressure value)
As a result, the compressors and the Airleader have the same pressure level.
Is one of the regulated compressors running in the uneconomic area, -e.g. at 100% or 30% for a longer period of time,
the actual pressure value is changed slightly by 0.05 bar until the compressors are running in the good range again.
Maximum adjustment 0.2 bar.
