Operation Manual
OFF, load shed functionality cannot be active. Fast load shed functionality is active
only if LSCACLS (core) function's Operation is set in ON mode.
If fast load-shedding is blocked, slow load-shedding is also blocked automatically.
However, manual load-shedding is independent and can be operated even when fast
and slow load-shedding modes are blocked.
Three out of the five functional keys in the LHMI can be configured (see the
engineering manual).
