Dump
Some action must be taken on RF power amplifiers to avoid an over-current when the beam is dumped (heavy beam loading). Just before normal beam dump switch RF off - All RF power equipment off. Pretty clear that having done this the beam dump MUST take place.

Ramp Down
The power converters will drive the magnets down as fast as possible (limit given by main bends ramp down rate of 10 A/s). This will done either using PELPs or functions. Power saving actions will be performed on the RF power amplifiers.
