Does the trip caused by MX Shunt or MN Undervoltage release get captured in the event history of Micrologic 5.0/6.0/7.0 E/P/H?

30 September 2021

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/H

For 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
