Fault indicators
Overview
In the event of a fault, the type of fault is indicated by the LED display on the sender or
receiver.
The information in the tables applies both for single devices and for every device in a
cascade.
When a device in a cascade shows a fault, the displays of the other devices in the
cascade must also be observed. The fault cause is only shown on the device in which it
occurs.
