AC-DC Power Supplies Enclosed TypeInstruction ManualCN1 or CN2OUTPUT1.10 Isolation＋S－S＋V－VWire as close as possibleC3＋C2＋R3C1R2Fig. 1.4 When using remote sensing function＋R1Load!When you run a Hi-Pot test as receiving inspection, graduallyincrease the voltage to start. When you shut down, decrease thevoltage gradually by using a dial. Please avoid a Hi-Pot tester witha timer because when the timer is turned ON or OFF, it may generatea voltage a few times higher than the applied voltage.PGTable 1.6 Description of the alarms (PG signal)AlarmOutput of AlarmFault conditionOpen collector method- Input voltage anomaly Good : L level- Thermal protection is activated.(0 to 0.5V at 3mA)- Overvoltage protection is Bad : H level or Openactivated.(35Vmax)- Overcurrent protection isactivated.- FAN stopPG/WRN0.1μF 100kΩ1.11 Signal Output (LED/Warning/Alarm)!Functions of LED indicators and Output of Warning/Alarm areshown below. LED indicators and Output of Warning/Alarm aresignals to check the presence/absence of voltage at the outputterminal of a power supply and to detect warning/fault conditions.The timing of signals might be vary depending on input and loadconditions. Please evaluate thoroughly.Table 1.4 Description of LED indicatorLED indicatorConditionOutput voltageOFFNo inputOFFBlue - ONNormal conditionONBlue - BlinkingOutput OFF by RC signalOFFAmber - BlinkingWarning condition(refer to Table.1.5)ONAmber - ONFault condition(refer to Table.1.6)OFFTable 1.5 Description of WarningsWarningOutput of WarningWarning conditionOpen collector method- AC input voltage is out of Good : L levelspecifi cation.(0 to 0.5V at 3mA)- Output voltage exceedsspecifi cation.Bad : H level or OpenWRN- Output voltage fall below (35Vmax)the setting value.-Overcurrent condition.-Overheat condition.-FAN alarmFig.1.5 Internal circuit of PG / WRNPGG/WRNG!Please note the followings for warnings (WRN signal) and thealarms (PG signal).1 The time it takes until the WRN signals and the PG signals turn”High”vary depending on conditions.2 If the output voltage is turned off through a remote ON/OFF circuit,the WRN signals and the PG signals keep”Low”.!The WRN signal (Warning) circuit and the PG signal (Alarm) circuitare isolated from input, output, FG and various function terminals.1.12 Sequence Diagram(1) Turn ON/OFF by Remote ON/OFF controlEventsACRCRCInputONOFFAC INPUTRCOutput VoltageAUXWRNPGONOFF0V0VNGOKNGOK300ms maxsignalinhibittime100ms max200ms max10-150msACLoss1.5s min8ms max2.1s min1.1s max：IndetermunateFig.1.6 Sequence time chart by Remote ON/OFF controlHFA-10
