ABB Relion 670 series - Function block; Input and output signals

There is an operation mode (OpModeSel) setting: 1 out of 3 or 2 out of 3. If the
parameter is set to 1 out of 3 any phase trip signal will be activated. If the parameter is
set to 2 out of 3 at least two phase signals must be activated for trip.
There is also a possibility to activate a preset change of the set operation current
(MultPU) via a binary input (MULTPU). In some applications the operation value
needs to be changed, for example due to transformer inrush currents.
PHPIOC (50) can be blocked from the binary input BLOCK.
