Voting Function
Fig. 4.5.6 e) Output events details screen – example of a VOTING combination
Example: Relay 4 of Module 3 is configured.
On the lower left side “Alarm 1” is marked. Therefore in the list of events only the
alarm 1 for all channels is indicated. Channels 1 to 5 of input module 1 are chosen.
The five marked channels are indicated in the right window “Selected Events”. Now
the function “Voting” is chosen and the menu “Voting Settings” occurs.
For the voting settings the options “1 out of X” , “2 out of X” and “3 out of X” with X
as number of events (maximum 6 events can be chosen).
In this example the relay will be triggered if two of the five chosen channels exceed
the level for Alarm 1.
The Box “Fault as Alarm” is chosen which means the relay will also be triggered if
one of the chosen detectors is in fault condition and a second one exceeds Alarm 1
and it will be triggered if two of the chosen detectors are in fault condition.
If the voting option “2 out of 2” or “3 out of X” is chosen, the command “Fault as
Alarm” will be activated automatically.
