4 / 8 page S82D S82D 4 Operation Remote Sensing Function This function corrects a voltage drop in the load wiring. When using the remote sensing function, remove the short bars from the remote sensing terminals as shown in the following diagram. Remote sensing connection (2-wire shielded cable) Load Load wiring Remove the short bar Note: 1. When the voltage drop in the load wiring is large, the overvoltage protection function might engage just from the increase in voltage to correct the voltage drop, so be sure to use high capacity wiring. 2. If the +S and +V terminals are left unconnected, the high voltage protection function will engage and the output voltage will be cut off. If the -S and -V terminals are left unconnected, the output voltage will increase about 5%. Remote Control Function This function allows the output voltage to be turned on and off with an external signal (as long as the input voltage is being applied). When using the remote control function, remove the short bar (at- tached at ex-factory condition) from the remote control terminals and connect a switch or transistor as shown in the diagram below. Remove the short bar Tr* *Use a transistor with VCE > 20 V and Ic > 5 mA. Level Output voltage L (0.8 V max.) ON H (2 V min.) OFF Note: The remote control circuit is insulated from input, output, and GR. Fan Alarm When the speed of the internal fan drops, the fan alarm output (SPST-NO) will turn ON (shorted).
