8.11 Setting the machine for master control operation
8.11.1 Overview of the different master operating modes
The controller offers several possibilities to work together with other controllers:
Method Description Section
Interconnected operation with SAM 4.0 The operating mode settings on the SIGMA
CONTROL 2 must be changed via a
SIGMA NETWORK to enable control by a
SIGMA AIR MANAGER 4.0.
8.11.2
Interconnected operation via
PROFIBUS
(only available with SIGMA
CONTROL 2 - prepared for connection
to control technology with optional
communications module)
The controller (and therefore the machine) re‐
ceives the instruction LOAD or IDLE
12)
via the
PROFIBUS master (e.g.
SIGMA AIR MANAGER). The network set-point
pressures pA and pB are irrelevant for activated
LOAD/IDLE signals.
8.11.3
Interconnected operation of two com‐
pressors with SIGMA CONTROL 2 via
Ethernet interface
The two SIGMA CONTROL 2 controllers oper‐
ate as master and slave. The slave receive the
command to switch between the two system set‐
point pressures pA and pB from the master.
8.11.4
Interconnected operation via LOAD re‐
mote contact.
Master control via a LOAD remote
contact is another method of control‐
ling the machine externally
LOAD remote contact 12) :
An input signal from a master controller switches
the machine to LOAD or IDLE. The nominal
pressure settings pA and pB have no relevance.
8.11.5
Local/LOAD remote contact
12)
:
Using two inputs, a master controller (e.g.
MVS 8000) switches the machine between
LOAD/IDLE and local operation.
8.11.6
Nominal pressure pre-selection pA/pB remote contact:
An input contact provides the signal to switch
from the system nominal pressure pA to pB.
8.11.7
Master control of machines regulated
by pressure switch
On machines with the same flow rate,
SIGMA CONTROL 2 controls the pressure
switch via a floating relay output.
8.11.8.1
On machines supplying an unequal flow rate,
the pressure ranges are matched to each other.
8.11.8.2

Tab. 69 Master control (interconnected operation) – overview
Further information Examples of timing programs for equal machine loading are given in section 8.11.9.
8.11.2 SAM 4.0 mode
You must modify the settings in SIGMA CONTROL 2 for the operation via SIGMA NETWORK us‐
ing, for example, the KAESER SIGMA AIR MANAGER 4.0 (SAM 4.0).
