Function Block; Signals - Hitachi Relion 650 Series Technical Manual

1MRK 511 557-UEN Rev. A
or ACT. Each LED is controlled by a GRP1_LEDx function block, which determines the color and the
operating mode.
By applying logical 1 to one of the inputs, a LED is activated in the corresponding color. In case more
than one input is active at the same time, red has highest priority, followed by yellow and green.
Each indication LED on local HMI can be set individually to operate in 6 different sequences; two as
follow type and four as latch type. Two of the latching sequence types are intended to be used as a
protection indication system, either in collecting or restarting mode, with reset functionality. The other
two are intended to be used as signalling system in collecting mode with acknowledgment
functionality.
