Indication of fault data
All faults detected by the relay are indicated on the front plate optically. For this purpose, the four
LEDs (L1, L2, L3, E) and the four function LEDs (I>, I>>, IE>, IE>> and
) are equipped at
MRI3. Not only fault messages are transmitted, the display also indicates the tripped protection
function. If, for example an overcurrent occurs, first the corresponding LEDs will light up. LED I>
lights up at the same time. After tripping the LEDs are lit permanently.
