Installation guidelines
The installation guidelines contain information about the possible
interference causes. Here we describe possible ways of interference that
may disturb the controlling system and how you have to approach shielding
and screening issues to ensure the electromagnetic compatibility (EMC).
Electromagnetic digestibility (EMC) means the ability of an electrical
device, to function error free in an electromagnetic environment without
being interferenced res. without interferencing the environment.
The Teleservice module is developed for applications in harsh industrial
environments and they comply with EMC requirements to a large degree.
In spite of this you should implement an EMC strategy before installing
your SPS and the Teleservice module, which should include any possible
source of interference.
Electromagnetic interferences may interfere your control via different ways:
•
Fields
•
I/O signal conductors
•
Bus system
•
Current supply
•
Protected earth conductor
Depending on the spreading medium (lead bound or lead free) and the
distance to the interference cause, interferences to your control occur by
means of different coupling mechanisms.
One differs:
•
galvanic coupling
•
capacitive coupling
•
inductive coupling
•
radiant coupling
