Error Reporting For setting the behavior if the active channel is faulty
By default only the warning "No Input" is created. It may however be
preferred that the transmitter should generate a fault message. In the
case of an n+1/1+1 system, the system would then switch over to the
standby transmitter.
This is good practice when, for example, in the case of a 1+1 standby,
there are two separate MPX feeds. In this case transmitter A can be
switched permanently to MPX Inp2 and transmitter B can be switched
permanently to MPX Inp3. In this case the indicated selection is Ch.1.
Report Type – Warning
The active channel creates only the warning "No Input".
– Fault
The active channel also generatesthe fault message "No Input".
When the channel is OK again, the defect is automatically reset.
