LED for that sensor will start flashing and the ERROR LED will
activate .
The Binary I/O LEDs indicate the I/O-line status . If any of the lines
become active for more than 1 .5 ms, the corresponding LED will
turn on (latch) .
In a trip situation, the corresponding trip LED will turn on . Trip
outputs are controlled by the dipswitch settings (see Section 3 .5) .
All activation and trip indication LEDs are latched, even if the
dipswitch setting is in the non-latched mode . They have to be
cleared by pushing the “SET” button .
LED indications are stored in non-volatile EPROM memory for iden
tifying the trip information in case the auxiliary power is lost . When
re-powering the relay after power supply loss, the actual LED status
can be visualized from the front of the relay
