Why is the Pfeiffer Vacuum Measuring Instruments display dark after switching it on?
If the display remains dark after switching on, there could be several reasons. First, there might be no supply voltage at the unit; check the mains connection and cable. Second, the mains fuses (2×10 AT) might be defective, requiring replacement. Finally, a loose display cable could be the cause; check the plug-and-socket connection on the display.
What to do if Pfeiffer Vacuum GSD 350 OMNISTAR turbopump switches off?
If the turbopump switches off, consider the following potential causes: * Overtemperature: Check the fans and service the turbopump. * High inlet pressure: Reduce the pressure on the inlet side of the capillary to < 1200 hPa. * Leakage: Check the capillary seal in the gas inlet area. * High fore-vacuum pressure: Check the vacuum connection between the diaphragm pump and turbopump for leakages. * Condensate in the diaphragm pump: Dismantle, clean, and dry the diaphragm pump parts. * Defective diaphragm pump: Service or replace the diaphragm pump.
What to do if Pfeiffer Vacuum GSD 350 OMNISTAR Measuring Instruments vacuum pumps switch off and the system shuts down?
If both vacuum pumps switch off and the system automatically shuts down, the issue could be due to overtemperature. Check the fans, clean the protection screens on the fans, and ensure the ambient temperature is within permissible limits. Alternatively, for corrosive gas versions, the sealing gas pressure may be too low, so check the sealing gas supply.
What to do if Pfeiffer Vacuum GSD 350 OMNISTAR Measuring Instruments turbopump fails to reach nominal rotation speed?
If, after the "Pump down" control command, the turbopump fails to reach the nominal rotation speed (icon remains dark green), allow the run-up time of less than 8 minutes to complete. For ThermoStar, ensure the inlet pressure is reduced to less than 1200 hPa. Check the capillary seal in the gas inlet area for leakages. Also, verify the vacuum connection between the diaphragm pump and turbopump for any leakages, as high fore-vacuum pressure can cause this issue.
Why won't the diaphragm pumps start on my Pfeiffer Vacuum GSD 350 OMNISTAR?
If, after the "Pump down" control command, the diaphragm pumps fail to start up (icon remains light gray), check the plug-and-socket connections on the diaphragm pump and the mainboard to ensure they are secure. The diaphragm pump could be defective, requiring servicing or replacement. For corrosive gas versions, verify that the sealing gas supply is adequate.
What to do if Pfeiffer Vacuum GSD 350 OMNISTAR Measuring Instruments diaphragm pump switches off?
If the diaphragm pump switches off, it could be due to several reasons. It may be caused by overtemperature, so check the fans and service the diaphragm pump. A loose cable connection could also be the cause, so check the plug-and-socket connections on the diaphragm pump and the mainboard. Alternatively, the diaphragm pump itself may be defective, requiring service or replacement.
What to do if "Dashboard" start screen does not appear on Pfeiffer Vacuum GSD 350 OMNISTAR Measuring Instruments?
If the "Dashboard" start screen does not appear after switching on, it may be because the run-up time has not completed. Wait for the run-up time of less than 60 seconds to complete. Another possible reason is that the unit was switched off and back on again too quickly. To resolve this, turn off the unit, wait for 15 seconds, and then switch it back on again.
What to do if Pfeiffer Vacuum GSD 350 OMNISTAR Measuring Instruments gas inlet valve fails to open?
If the gas inlet valve fails to open (only for OmniStar), it could be because the delay time for valve opening has not yet completed; wait for the delay time of less than 7 seconds to complete. The gas inlet valve may not be controlled, so check the plug-and-socket connections on the gas inlet valve and the mainboard. The gas inlet valve might be polluted or defective, requiring replacement of the valve block.
What to do if Pfeiffer Vacuum GSD 350 OMNISTAR Measuring Instruments pressure in vacuum chamber is too low?
If the pressure in the vacuum chamber is too low (< 1 × 10-6 hPa) for ThermoStar and/or OmniStar with an open gas inlet valve, it could be due to low inlet pressure; increase the pressure on the inlet side of the capillary. Alternatively, the capillary might be blocked, so trim or replace it. The orifice could also be blocked, requiring replacement.
Why does Pfeiffer Vacuum Measuring Instruments turbopump fail to start up?
If, after the "Pump down" control command, the turbopump fails to start up (icon remains light gray), it could be due to several reasons: * The switch-on vacuum of 10 hPa has not yet been reached: wait for the pump down action for the fore-vacuum to complete (target < 60 s). * High moisture content in the vacuum system: bake out the vacuum chamber. * Condensate in the diaphragm pump: dismantle and clean the diaphragm pump, then wipe the parts dry. * Defective diaphragm pump: service or replace it. * Loose cable connection: check the plug-and-socket connections of the electronic drive unit and the mainboard. * Defective turbopump: replace it.
