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
