Auto
When set to Auto , fault detection is enabled, the outputs will automatically default to the Primary inputs, and, when
applicable, automatic switching of inputs occurs when a fault is encountered:
When a Primary fault is repaired, the output will automatically switch back to the Primary input when the signal is
re-connected (provided the signal conforms to that channel's configuration).
Manual
When set to Manual , fault detection is “disabled”, and the user is able to manually switch the output to be either the
Primary or Backup input, irrespective of any existing faults.
Output
This menu line displays which of the inputs is currently switched to the output. The options for the field are:
Primary, Backup. The user can only switch the output to Backup when the “Operational Mode” is set for “Manual”.
