Backup Amplifier Configuration

This article describes how to configure the backup amplifier functionality.

Standard backup amplifier configuration

The backup functionality is configure in EMT:

• In Components view select Devices and Rack Mounted Devices
• Drag-and-drop the desired ENA amplifier on top of the System.

Backup Amplifier functionality configuration

• In the pop-up window select Add as backup amplifier and push Done.

This amplifier is now configured as an backup amplifier.

To configure which amplifier(s) to backup for you have to configure the control outputs on the backup amplifier:

• Select the backup amplifier in the System (device tree).

Backup Amplifier Control Output configuration

• Amplifier drop-down: Select the desired amplifier for the control output.
• Priority: It is possible to assign priority to the amplifier being monitored. This means that if more than one amplifier fails it will take over the amplifier with the highest priority. This also means that if first one amplifier fails, and then later an amplifier with higher priority fails it will take over latter the amplifier

Optional switch-over functionality

In addition, an optional function on a control input on the backup amplifier can trigger the backup functionality.
This will ensure an even faster switch-over if the defect amplifier has a power issue.

On the backup amplifier you need to configure a control input:

• In Components view select Input Actions and Backup Request.
• Drag-and-drop the Backup Request to a Control Input on the backup amplifier.

Backup Request configuration

• Select the desired amplifier.
