  • Page 97 ANALOG CONTROL The Ext-R configuration is recommended for Note safety reasons. In the event that the cables become accidentaly disconnected, the current output will drop to zero. Under similar circumstances using Ext-R , an unexpected high current would be output. If swtiches are used to switch between fixed resistances, use switches that avoid creating open circuits.

    ANALOG CONTROL External Operation and Status Monitoring Background The MIL 26 pin connector can also be used to monitor the status operation and alarm status of the instrument. The pins are isolated from the power supply internal circuitry by photo couplers. Status Com (Pin 17) is a photo coupler emitter output, whilst pins 18~22 are photo coupler collector outputs.
