1. Select Transmitter > Exciter > Modulation .
The Modulation window opens.
Selection For selecting the active channel
Possible selections:
– Ch.1
– Ch.2
– Auto (automatic input selection): The best available channel is
selected according to the following priority:
1.) Ch.1 is OK.
⇒
switch to Ch.1
2.) Ch.2 is OK.
⇒
switch to Ch.2
3.) In Ch.1 there is one channel OK.
⇒
switch to Ch.1
4.) In Ch.2 there is one channel OK.
⇒
switch to Ch.2
5.) Switch to Ch.1
State Displays the active channel: Ch.1 or Ch.2
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.
Fail Delay For setting a time interval after which, in the event of a "No Input" warn-
ing, the "No Input" fault message also has to be generated
Only active when Report Type is set to Fault .
a) Since switchovers are allowed for certain combinations only, the number of options offered for selection is
limited depending on the settings for channel 2. To display all possible choices, channel 2 (secondary) must
be set to "Not Used".
b) Since switchovers are allowed for certain combinations only, the number of options offered for selection is
limited depending on the settings for channel 1.
