Similarly, the user can set up a comparison of three values. The table below presents the available
modes for a three-signal comparison.
Mode
Description
0: Mag1 x Mag2 x Mag3
Multiplies Signals 1, 2 and 3. The comparison uses the product of this calculation.
1: Max (Mag1, Mag2, Mag3); The biggest value of the chosen signals is used in the comparison.
2: Min (Mag1, Mag2, Mag3)
The smallest value of the chosen signals is used in the comparison.
3: Mag1 OR Mag2 OR Mag3
Any of the signals fulfills the pick-up condition. Each signal has their own pick-up setting.
4: Mag1 AND Mag2 AND
Mag3
All of the signals need to fulfill the pick-up condition. Each signal has their own pick-up
setting.
5: (Mag1 OR Mag2) AND
Mag3
Signals 1 OR 2 AND 3 need to fulfill the pick-up condition. Each signal has their own pick-up
setting.
The image below is an example of setting an analog comparison with three signals. The stage will trip if
Signal 1 or Signal 2 as well as Signal 3 fulfill the pick-up condition.
