When two or three signals are chosen for comparison, an additional signal (
PSx Magnitude handling)
setting appears. From its drop-down menu the user chooses how the signals are pre-processed for
comparison. The table below presents the available modes for a two-signal comparison.
Mode
Description
0: Mag1 x Mag2
Multiplies Signal 1 by Signal 2. The comparison uses the product of this calculation.
1: Mag1 / Mag2
Divides Signal 1 by Signal 2. The comparison uses the product of this calculation.
2: Max (Mag1,
Mag2)
The bigger value of the chosen signals is used in the comparison.
3: Min (Mag1,
Mag2)
The smaller value of the chosen signals is used in the comparison.
4: Mag1 OR Mag2
Either of the chosen signals has to fulfill the pick-up condition. Both signals have their own pick-up
setting.
5: Mag1 AND Mag2
Both of the chosen signals have to fulfill the pick-up condition. Both signals have their own pick-up
setting.
6: Mag1 – Mag2
Subtracts Signal 2 from Signal 1. The comparison uses the product of this calculation.
The image below is an example of setting an analog comparison with two signals. The stage will trip if
either of the measured signals fulfills the comparison condition.
