5-56 B90 Low Impedance Bus Differential System GE Multilin5.3 SYSTEM SETUP 5 SETTINGS55.3SYSTEM SETUP 5.3.1 AC INPUTSa) CURRENT TERMINALSPATH: SETTINGS SYSTEM SETUP AC INPUTS CURRENT TERMINAL F1(S8)This menu configures the AC current inputs. Upon power up, the B90 recognizes all the AC modules loaded in its chassisand populates the above menu accordingly.The current terminals are denoted in the following format: Xa, where X = {F, L, S} and a = (1, 2,..., 8}. X represents thechassis slot containing the AC input module and a represents the AC channel of each module. For example, a B90 unitcontaining the F8H and L8K modules displays the following current inputs for configuration: F1, F2, F3, F4, F5, F6, F7, F8,L1, L2, L3, L4, L5, L6, and L7.b) VOLTAGE TERMINALSPATH: SETTINGS SYSTEM SETUP AC INPUTS VOLTAGE TERMINAL F1(S8)This menu configures the AC voltage inputs. Upon power up, the B90 recognizes all the AC modules loaded in its chassisand populates the above menu accordingly.The voltage terminals are denoted in the following format: Xa, where X = {F, L, S} and a = (5, 6, 7, 8}. X represents thechassis slot containing the AC input module and a represents the AC channel of each module. For example, a B90 unitcontaining the F8F and L8K modules displays the following voltage inputs: F5, F6, F7, F8, and L8.The nominal VT F1 SECONDARY setting is the voltage across the relay input terminals when nominal voltage isapplied to the VT primary.
