This value is saved in the fault memory when below the pick-up value or in case of tripping. For an inverse
time characteristic the pick-up time during the pick-up phase is stored.

6.3 Displaying the pickup phase
If a pickup value is exceeded, the display will show the pickup time.
If the pickup value drops below the threshold before tripping takes place, the measuring values are dis-
played.
6.4 Display of tripping values
>>>>>FAULT<<<<<<
>>>>MEMORY_1<<<<
The fault memory provided in the WIP1-1 can save up to five trip events. The individual registers are select-
ed by push buttons <+> and <->. Configuration of all registers is identical.

In the display an overcurrent trip with current increase in phase L1 is shown. Currents in the other two phas-
es were below the trip value.
The following faults can be displayed:

Here the current values at the trip instant are displayed in ampere.
These values are not displayed if the event is of energizing nature only.
A peak value measured at the C.T. during the pick-up phase is displayed.
