Selecting this operating mode minimizes the number of switchover operations and, in
certain cases, the number of breaks in transmission.
Direction of switchover (Switch to)
The "to reserve and back"
switch position enables switchover in both directions, i.e. to
and from the standby input, depending on which of the two logical inputs is currently
faulty.
The "reserve" switch position ensures that switchover takes place once only. Following
switchover, the automatic system switches to "switched" and the "Active" indicator dis-
appears.
Switchback to the preselected input takes place when the active input is switched over
by pressing the input selector switch (Selector) and then selecting the preselected
input.
If the switch is set to "reserve", the switchback to the preselected input is suppressed.
Manual switchover between inputs
The input can be switched over in the
"Home" > "Transmitter" > "Exciter" menu by
pressing the input selector switch ("Selector") and then selecting the desired input.
Depending on the configuration and switching state (ON/OFF) of the automatic input
signal switchover function, this menu contains either the switch used to change the
preferred input or the switch used to switch over the active input.
The automatic input signal switchover function is configured in the following way:
1. Navigate to the following destination using the menu bar:
"Devices" > "Tx<n>" > "Exciter A|B" > "Input Auto"
2. The following parameters must be defined on the Automatic tab:
a) for Configuration:
● Automatic:

● Guard Time to Reserve:
● Guard Time Back:
