2.2.5 Parameter setup governor relay
The PPU-2 standard unit controls the governor on relay output terminals 65-68, slot #4, these are not configu-
rable. The PPU-3 standard unit has four configurable relay outputs, placed in slot #4, terminals 65-72. The
table below shows the differences in the standard parameter settings.
