• Analog channels (1...4) allocation.
• Digital channels allocation (output relay and/or binary inputs).
• Trigger setup; the information storage starts when a state transition on the selected signal occurs.
(protective element start and/or trip, output relay and/or binary input switching).
Example 1
With the following setting:
• Analog channel 1:
i
L1
