Foreword
Micro Automation Sets are fully functional and tested automation configura-
tions based on A&D standard products for easy, fast and inexpensive im-
plementation of automation tasks in small-scale automation. Each of these
Micro Automatic Sets covers a frequently occurring subtask of a typical
customer problem in the low-end range.
The sets help you to obtain answers with regard to required products and
the question how they function when combined.
However, depending on the system requirements, a variety of other com-
ponents (e.g. other CPUs, power supplies, etc.) can be used to implement
the functionality on which this set is based. Please refer to the respective
SIEMENS A&D catalogs for these components.

Application Areas and Usage
Application Areas
This configuration is suitable for the following tasks:
•
Monitoring of DC 24V load feeders
•
Detecting overload and short circuit
In the preferred fields of application of the configuration, the following tasks
have to be solved:
•
Several DC 24V load feeders are operated at one power supply (used
to divide the load current).
•
Individual load feeders are to be secured selectively, in order to prevent
a total system failure in case of a fault
•
The selective protection is also to be achieved in widely distributed
plant parts and in remote loads (distributed configuration).
•
Connecting users which cannot be secured via quick circuit breakers
and with high switch-on power consumption.
•
Quick error localization
Benefits
•
Preventing complete system failure if a DC 24V power supply failure
occurs in case of a fault.
•
Only the faulty line is switched off.
•
Minimizing the downtimes by localizing the faulty line on LOGO!) Dis-
play
•
Commissioning of the system/maintenance can be performed modular
by simple plugging and pulling the blade-type fuses.
•
Configuration can be expanded later.
•
A central overview of the status of all load feeders is enabled by mes-
sage texts on LOGO!.
