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).
The term "electromagnetic compatibility" (EMC) refers to the ability of an
electrical device to operate properly in an electromagnetic environment
without interference from the environment or without the device causing
illegal interference to the environment.
The TM-E 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
TM-E 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
