The advantage of having a relay configured for normally energized operation is that
in the event of the rack losing power, the relay would immediately switch to a fault
condition.

Latching
When the relay is set for "Latching" and the relay is activated, it will stay in that
state until it is reset. Resetting can be done via either:
–
–
–
–
Having to manually reset a fault condition ensures that all such conditions have to
be acknowledged and acted on by someone.

Name
A 20 character field which can usefully be used to identify the relay name or tag.
Note that, for relays, this text is only stored in the project and not in the actual
configuration.

Comment
A free text field for additional information. Note that this text is only stored in the
project and not in the actual configuration.

Enter Delay
This represents the time in milliseconds that an alarm or danger condition has to
exist before the selected relay is activated into its alarm state.

Leave Delay
This represents the time in milliseconds after an alarm or danger condition has
ended before the selected relay is deactivated from its alarm state.
Note: Leave delay is not applicable to a relay configured as Latching.

Channel Setup
Channel setup options are basic channel setup voting based on "n out of N" logic.
Detailed information is provided in the next section,
