Within each instance of analog input there are settings forall 12 channels that include the name of the channel, star point of the CT circuit,the primary and secondary values from the measuring transformers (CTs). Thechannel type and ratings are shown but cannot be changed.The settings for binary inputs and outputs even include the milliampere inputmodules. A mix of up to 14 instances of BIM, BOM and IOM is possibledepending on the physical configuration of the IED. Operation ON or OFF can beset for all of these and for the BIMs oscillation release and oscillation blocksettings are available. These settings are on board level and apply to all binaryinputs or outputs on a board.9.2.3.2 Analog modulesMain menu/Settings/General Settings/Analog modules/AnalogInputsDisplays all configurations of analog current input modules with parameters. Eachchannel has parameters where the type of channel is set, the primary and secondaryvalues from CTs and for Current Transformers the star point location (line side orbusbar side) is set.Main menu/Settings/General Settings/Analog modules/MergingUnitDisplays parameters for the merging units. For the MU channels, no primary orsecondary values need to be set, due to the fixed standardized scaling of 1 mA/10mV per LSBMain menu/Settings/General Settings/Analog modules/3PhaseAnalogGroup/SMAIX:YHere, settings for the Fourier filters, the minimum system voltage required tomeasure frequency, the item designation of CTs are set. These settings are requiredby the preprocessing blocks and are usually only adjusted during the initialengineering phase.1MRK505209-UEN E Section 9Read and change settings47Operator's manual
