This information is used in the shortperspective to get information via the local HMI in a straightforward way.There are three LEDs on the local HMI (green, yellow and red), which will displaystatus information about the IED and the Disturbance recorder function (triggered).The Indication list function shows all selected binary input signals connected to theDisturbance recorder function that have changed status during a disturbance.1MRK 511 287-UEN A Section 12Monitoring455Technical manual
