GPU – User’s manual Optional function list Note: Option A and B cannot be chosen at the same time as they contain common functions. Option A, mains failure supervision - Vector jump Df/dt (ROCOF) Overvoltage (2 levels) Undervoltage (2 levels) Overfrequency (2 levels) Underfrequency (2 levels) Option B, voltage / frequency protection package - Overvoltage (2 levels) Undervoltage (2 levels) Overfrequency (2 levels) Underfrequency (2 levels) Option C, generator add-on protection package - Over load (2 levels) Current asymmetry (1 level) Voltage asymmetry (1 level) Loss of excitation (1 level) Over excitation (1 level) Option F1, 2 x transducer output Selecting option F1 means that an additional board will be placed in slot #6 (terminals 90 to 97) where 2 analogue 0(4)…20 mA outputs will be present. The outputs are galvanically separated from each other and the rest of the GPU. The outputs are active outputs (does not require external power supply). The use of the analogue outputs can be selected via the menu system or the PC programming interface. Option F2, 4 x transducer output Option F2 will, in addition to the 2 analogue outputs in slot #6 as described under Option F1, place 2 analogue outputs in slot # 4 (terminals 65 to 72). The technical data are the same. Option G, Start / stop of next generator If option G is selected, an additional relay board is mounted in slot #8 (terminals 126-133). Start signal is on terminals 126-127, stop signal is on terminals 128-129. Both are normally open relays. The settings of level and timers can be carried out in the menu system or via PC interface. 4189340228D Page 5/39
