6F2S1931 (0.20)Centralized GRB200(Soft: 030, 031, 032, 033, 034)- 280 -Table 4.4-4 Threshold voltage of picking-up / dropping-off for binary inputs(a) In the case of DC rated voltage “110-250 Vdc”Voltage level Threshold voltage of picking-up / dropping-off for binary inputsHow to set NoteHigh Typical 136V Selection switch[THRES_Lvl] = High —Low Typical 71V Selection switch[THRES_Lvl] = Low This is default.(b) In the case of DC rated voltage “24-60 Vdc”Voltage level Threshold voltage of picking-up / dropping-off for binary inputsHow to set NoteHigh Typical 30V Selection switch[THRES_Lvl] = High —Low Typical 15V Selection switch[THRES_Lvl] = Low This is default.As the threshold voltage is expressed with Table 4.4-4, the user should set High or Low tomatch to the voltage value to input to binary inputs. Table 4.4-5 shows the recommendedsettings.This matter means that the user should also set a threshold voltage at the power supply unitto determine the degree of the power failure (seeChapter: Technical description: Power supplymodule).Table 4.4-5 Recommended setting for the voltage level(a) In the case of DC rated voltage “110-250 Vdc”Voltage valueto input to binary inputs Recommended setting for the voltage level250V220V High125V110V Low(b) In the case of DC rated voltage “24-60 Vdc”Voltage valueto input to binary inputs Recommended setting for the voltage level60V48V High30V24V Low
