AC-DC Power Supplies Confi gurable TypeInstruction ManualOutput moduleCN3OUTPUT＋S－S＋V－VR2Wire +S and ?S as close as possibleC1＋R1LoadFig. 3.6 Use example of remote sensing3.12 Variable speed fan!The power supply has built-in variable speed cooling fan.The fan speed changes by load and ambient temperature.3.13 Global inhibit (GI)!The unit has the Global inhibit function.Global inhibit is the control signal input which turns all outputs offby supplying the current into GI2.Table 3.2 is specifi cations and Fig.3.7 is use examples for Globalinhibit.!The Global inhibit circuit (GI2, GIG) is isolated from the input, outputs,FG, AUX and other function terminals.!Please note the following when using the Global inhibit function.1 The output can be turned off by supplying the current into GI2pin.2 The current into GI2 pin is 3mA typ (12mA max).3 The PR signal will get“High”when all output modules areturned off by the Global inhibit function.4 When stopping outputs by Global inhibit, the built-in fans alsostop.5 AUX is available even when outputs stop by Global inhibit.6 When stopping outputs by Global inhibit, the derating is requiredfor AUX. Please refer to the item 3.16.7 If the voltage or the current which exceeds the value in table 3.2were supplied into GI2 pin, the output might not be generatedcorrectly.8 Start time is 1,000ms max.Table 3.2 Global inhibit specifi cationConnection method Fig. 3.7 (a) Fig. 3.7 (b) Fig. 3.7 (c)SW open SW open SW shortOutput onSW(0.1mA max) (0.1mA max) (0.5V max)LogicSW short SW short SW openOutput off(1.5mA min) (1.5mA min) (0.1mA max)Bases pin GIG AUXG GIG,AUXG5Vtyp2.2kΩ150ΩCN1GI1GI2R1GIGAUXGExample R1:1kΩV1:5V(a)3.14 IsolationV1SW5Vtyp5Vtyp2.2kΩ150Ω(b)2.2kΩ150Ω(c)Fig.3.7 Connection examples for Global inhibitCN1AUXGI1GI2GIGSWAUXGCN1AUXGI1GI2GIGAUXGSW!When the Hi-Pot test for the receiving inspection, etc is conducted,the voltage should be increased gradually. Also, when shuttingthe voltage off, it should be decreased gradually by using the dial.Please do not use the Hi-pot tester which has the timer because itmight generate unwanted high voltage when timer is on.!When the isolation test between“the input and outputs”,“the inputand FG”and“outputs and FG (Except output module V, V4, V5)”is conducted, all outputs and terminals for all functions should beshorted.! When the isolation test between“outputs and FG (output modulesV, V4, V5)”is conducted, output and the function terminal of CN3should be shorted.* If the other function terminals are not opened, the internal componentsmight be damaged.AME-18
