Voting [Alarm Logic]
Field type: Number input
The value entered in this field applies to the configuration conditions described above. Optional
combinations [alarm, fail, and inhibit] can be formed when the selected relay output is configured.
The number value selected in this field determines how many of the conditions configured in the
control boxes must be met for the selected relay output to be switched. 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 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.
Voting link: [n-out-of-m]
If ‘m’ conditions are set, and the value of ‘n’ is entered as the voting, then the selected relay output
will only be activated if ‘n’ out of the ‘m’ conditions are met.
OK
Field type: Button
Tap this button to accept the settings entered for the selected relay output. After the button is
pressed, the voting settings are checked to see whether they are valid. If the settings are valid,
they become part of the system’s parameter set. If they are not valid, a warning appears.
Cancel
Field type: Button
Tapping this button discards the settings entered for the selected relay output.
Advice for multiple links: When creating multiple links the digital outputs with a high
number of links must be selected to the lower numbered [9–256] switch outputs. After
entering the links the system makes a link calculation and the total number of links will
be recorded in the system logbook. If the value of the link calculation exceeds 63, a
warning is shown. The system will refuse a value over 70 and the user has to reduce the
number of link settings.
