AC-DC Power Supplies Enclosed TypeInstruction Manual1.8 System ON/OFF!System ON/OFF controls output voltage On/Off and Remotesignal ON/OFF by open/short terminals (SCHA10000T : CN7,8SCDA10000T : CN5,6).System ON/OFF specification is on Table1.1.A connection example is on Figure1.4. Connector locations andpin assignment are shown on the external view.!System ON/OFF circuit is isolated from all of the others which areinput, output, FG, Remote signal ON/OFF and Alarms.!System ON/OFF sequence diagram is explained in 1.12.Table1.1 Specifi cations of system ON/OFFOutput System ON/OFF Remote signal ON/OFFShort(Low)LowON(Less than 1V, less than 5mA) (0-0.5V, less than 1000mA)Open(High)High or OpenOFF (Open voltage 2.5V-5.0V)(Absolute maximum rating 30V)(Absolute maximum rating 30V)systemON/OFF+SWInternal circuitsystemON/OFF-Fig.1.4 Example of System ON/OFF1.10 Alarms!The alarm signal detailed on Table1.2 is sent out from the alarmterminal (SCHA10000T : CN9,10 SCDA10000T : CN7,8) . Pin assignmentis shown on external view.Alarm specifi cation is on Table1.3.The internal circuit is on Figure 1.6.!Alarm diagram is explained in 1.12.Table1.2 An alarm generated conditionAn alarm generated condition(1)Low input voltage (AC160V or less) or disconnection of onephase of three phase line.(2)Thermal protection is activated and shuts down the output voltage.(3)Decreased output voltage and the low-voltage protection is activated.(4)Shut down output voltage and the low-voltage protection is activated.(5)Overvoltage protection is activated and shuts down the outputvoltage.(6)Over current protection is activated and decreases the outputvoltage.(7)Turn off AC power source, then recycle AC within 3 seconds.This condition keeps off the output voltage with sending out thealarm.Table1.3 Specifi cations of alarmcondition of power supplyOutput of AlarmgoodLow (0-0.5V, less than 200mA)bad High or Open (Absolute maximum rating 30V)1.9 Remote Signal ON/OFF!Remote signal ON/OFF switches an external power supplyON/OFF such as DC/DC converter (SCHA10000T : CN1 - 4,SCDA10000T : CN1,2) .The internal circuit is on Figure 1.5.Remote signal specifi cation is on Table1.1.Connector locations and pin assignment are shown on the externalview.!The remote signal ON/OFF circuit is isolated from all of the otherswhich are input, output, FG, System ON/OFF and Alarms.!Remote signal ON/OFF sequence diagram is explained in 1.12.Alarm +Alarm -Fig.1.6 Internal circuit of Alarm!Alarm circuit is isolated from input, output, FG,system ON/OFFand Remote signal ON/OFF.Remote signalON/OFF +Remote signalON/OFF -Fig.1.5 Internal circuit of Remote signal ON/OFFSC-12
