In the configuration matrices, shown as a table, it is possible to set the conditions for each
input (1
st
to 4
th
alarms, failure, inhibited) that must be met for the selected relay output to be
activated.

Alarm:
Select the alarms that will activate the selected relay, for each input. When the menu is opened,
the alarm that was selected in the input menu will be highlighted.
• Failure:
If this condition is set, the selected relay output is activated when a problem occurs for the
corresponding input.
• Inhibit:
If this condition is set, the selected relay output is activated when the corresponding input is
inhibited.
Voting (Alarm Logic)
Field type: Integer
The value entered in this field applies to the configuration conditions described above. Optio-
nal status combinations (alarm, failure, locked) can be formed when the selected relay output
is configured. Up to 256 configuration conditions per relay output are permitted. The number
value selected in this field determines how many of the conditions configured in the check
boxes must be met for the selected relay output to be activated. The number of conditions
entered in the check boxes is displayed in the field beside the voting to be configured.
The following types of links can be formed in this manner:
Single link: (1-out-of-1)
Exactly one condition is set, and the value of 1 is entered as the voting.
“OR” link: (1-out-of-m)
Multiple conditions are set, and the value of 1 is entered as the voting, i.e., if any one or more of
the set conditions are met, the relay output will be activated. Parameters for a global alarm or
common alarms can be set in this manner.
“AND” link: (m-out-of-m)
The value entered for the voting corresponds to the number of set conditions, i.e. all of the set
conditions must be met for the relay output to be activated.
