The LValarm is isolated from input, output, and FG.V.ADJAC(L)FG AC(N)AC(L)LVGFig.5.21 LV internal circuitTable 5.14 LV alarm operating conditionsAlarmOutput of alarmIf the output voltage drops or Open collector methodstops, the LV and LVG terminalsgive an alarm signal.Note : 1In case of overcurrent,the alarm signal will beLVunstable.2The alarm signal won’tbe given in paralleloperation if OR diodesare not used.■Remote sensingGood : Low(0 - 0.8V, 10mA max)Fail : High or Open50V 10mA max-These models are equipped with a remote sensing function.If the remote sensing is not used, the following terminals of CN1must be shorted:+S and +M?S and ?MWhen the power supply is shipped from our factory, a designatedharness (H-SN-31) is attached to CN1. If remote sensing is notused, there is no need to remove the harness.-The wire connection when remote sensing is used or not used isshown in Fig. 5.22 - Fig. 5.23.-When using remote sensing, make sure to finish wiring +S and ?S first. The designated harness is available for sale. Contact usfor more details.-When using remote sensing, pay attention to the following:1 Wiring must be done carefully. If there is bad connection on theload lines due to loose screws, etc., the load current flows intothe sensing lines and the internal circuit of the power supply maybe damaged.2 Make sure the wires between the load and the power supply arethick enough to keep the line drop less than 0.3V.3 If the sensing wires are long, place C1 and R1 across the loadlines.4 Use a twisted pair wire or a shielded wire for the sensing lines.5 Do not draw the output current from +M, ?M, +S or ?S.6 The impedance of the wiring or the load may cause the outputvoltage to oscillate or fluctuate.Test to confirm remote sensing works fine. If the output voltage isfound to be unstable, the following methods are recommended:- Remove the remote sensing line on the minus side and short?S and ?M.- Use C1, R1, and R2.PJMA-19May 09, 2025
