Example: Two machines with different delivery quantities
Local operating mode of the master: Local mode pA/pB Clock.
■ Toggles between system pressure setpoints pA and pB by a clock program.
■ At peak load times, pressure is regulated to system set-point pressure pA.
During periods of low air demand, pressure is regulated to system setpoint pB (e.g., at week‐
ends).
■ The machine with the lesser air delivery is the slave.
In times with lower air demand, the machine with the smaller delivery is used more frequently.
Example: Two machines with equal delivery quantities
■ Local operating mode of the master: Local mode pA/pB Cycle.
(Toggles between system pressure setpoints pA and pB by a clock).
The clock ensures even loading of both machines. The system pressure setpoints are set the
same for both machines.
■ During timer period 1, the master regulates to pA and signals the slave for pB.
During timer period 2, the master regulates to pB and signals the slave to pA.
If two machines SIGMA CONTROL 2 are to work in master-slave mode, their controllers must
have the same software version.
➤ Follow the configuration steps as described in table 63 .
Controller Procedure Chapter
Both Establishing the electrical connection 7.9.4.1
Both Set system pressure setpoints pA and pB. The pressure for switch‐
ing points pA and pB is measured directly at the compressor. Pres‐
sure losses in the network do not need to be taken into account.

Tab. 63 Master-slave configuration procedure
7.9.4.1 Establishing the electrical connection
Prepare the following for the Ethernet connection:
■ Ethernet cable, 100 m maximum, depending on connection.
■ For each machine with SIGMA CONTROL 2 :
─ Ethernet connector set
■ For connecting the machines to a network (LAN):
─ 2 Ethernet connection plugs
➤ Make the electrical connections as shown in the table below.
