The trip caused by MX shunt or MN undervoltage release will not be recorded in event history of Micrologic 5.0/6.0/7.0 E/P/H
The Micrologic wouldn't know if this trip is due to a fault or not.
The trip history is the means to display at any time the parameters measured during the last ten trips.
Accessing trip history is different in Micrologic E to Micrologic P/HFor Micrologic E:For Micrologic P/H:
For each trip, the following parameters are recorded:
- tripping cause
- trip threshold
- interrupted currents in amperes (only if an external power supply is present) for Ir, Isd/Ii, Ig or I∆n trips
- date v time (hours, minutes and seconds).
From the main menus you can access the event history as follows
When you enter Event history you will find Trip history as shown below:
