Hardware GuideDocument Number: D1000092206 B 13Interlocks (pressure switches) monitored by the firmware detect if the Curtain Gassupply and the roughing pump are switched on. If the interlocks are not satisfied,the turbo pumps are not initiated.CAUTION! If the ion source is removed, the system electronics will be disabled,interrupting any data acquisition tasks. The turbo pump and the vacuum system will notbe affected.1. Turn on the roughing pump, if it was turned off. The power switch islocated beside the power supply input attachment on the roughingpump.2. Make sure that all gas supplies are flowing correctly to the instrument.3. Plug the mains power cord into the bulkhead.4. Turn on the main power switch.5. Make sure that the GPIB (general purpose interface bus) cable isconnected to both the instrument and the computer.6. Turn on the computer, if it was turned off, and then start the Analyst®software.Source/Gas ParametersThe parameters in Table 1-1 are optimized for different LC conditions involvingflow rate. For more information about the parameters, see the Analyst® softwareHelp system.Note: The roughing pump has its own power toggle switch and must be turnedon manually. The roughing pump is not controlled remotely by the systemcontroller.Note: We recommend that you run the instrument with the Curtain Gas™ flow set to atleast 20 to maintain good instrument performance.Table 1-1 Source/Gas ParametersParameter ValueCurtain Gas (CUR) 20IonSpray Voltage (IS) 5000Temperature (TEM) 700Ion Source Gas (GS1) 60Ion Source Gas 2 (GS2) 60
