Table 5 3 Rear panel subsystem menu 71 TDKLambda 5 7 1 External Shut Off Function SO signal serves as Output Shut Off It is an optically isolated signal from the power supply output Connection to the signal is made via pin J3 5 Shut Off and pin J3 7 IFC_COM The SO pin accepts a 2 5V to 15V signal or Open Short contact to disable or enable the power supply output The SO function will be activated only when a transition from On to Off is detected after applying AC power to the unit Thus in Auto start mode the output will be enabled after applying AC power even if SO is in Off level After On to Off transition is detected the SO will enable or disable the power supply output according to the signal level or the short open applied to J3 When the external SO is triggered the power supply will display 50 on the voltage display but the PROT LED will not illuminate The external shutdown is useful when using the power supply as part of a larger test system in which digital or analog control is required or in Daisy Chain The SO control logic can be selected via the Front panel as follows 1 Press MENU button MENU GREEN LED illuminates Et message appears on the Voltage display and r PAf message appears on the Current display 2 Press Current encoder The 50 message appears on the Current display 3 Press the Current encoder again The 50 message appears on the Voltage display Parameter POS or
