If the Siemens Medical Equipment indicates a Filament Inverter short - circuit, verify if FMAX is not adjusted and check for IGBT short-circuits.
What to do if Siemens POLYMOBIL Plus Medical Equipment shows KVact ? 0?
If the Siemens Medical Equipment displays 'KVact ? 0', check if there is a connection to the single tank generator (D915 X8) and verify the plug-in connection on D900 in the single tank generator.
What to do if Siemens Medical Equipment shows mAact ? 0?
If the Siemens Medical Equipment displays 'mAact ? 0', check for an error in the measurement acquisition on D915 and consider replacing D915. Also, verify the connection to the single tank generator (D915 X8) and ensure the plug-in connection on D900 in the single tank generator is secure.
How to troubleshoot + 15 V - Error in Siemens POLYMOBIL Plus?
To troubleshoot a '+ 15 V - Error' in Siemens Medical Equipment, check the fuse on power supply U1 and determine if power supply U1 is defective.
What causes Inverter Error in Siemens Medical Equipment?
If the Siemens Medical Equipment shows an Inverter Error, check ribbon cable X20, verify if FMAX is not adjusted, and check for IGBT short-circuits.
What causes maximum preparation (preparation time too long) on Siemens POLYMOBIL Plus Medical Equipment?
If the Siemens Medical Equipment experiences maximum preparation time being too long, it may be due to the prep level being pressed for too long.
Why is the capacitor bank not ready on my Siemens device?
If the capacitor bank is not ready on your Siemens Medical Equipment, it may be because the device was not ready or had not released yet. Check if F1 on D950 is defective and investigate for errors on D950.
What does Vfil > Vmax (Max. Filament heating exceeded during preparation) mean on Siemens Medical Equipment?
If the Siemens Medical Equipment displays 'Vfil > Vmax' (Max. Filament heating exceeded during preparation), it indicates an error during the acquisition of the filament heating. Check if the basic value of the exposure filament is incorrectly set (P5 on D915) and investigate for errors on D915.
What to do if Siemens Medical Equipment indicates a short circuit in main inverter?
If the Siemens Medical Equipment indicates a short circuit in the main inverter, check D960 and D915. Also, verify if the main inverter frequency is too high.
What does it mean if the pressure switch is active in Siemens Medical Equipment?
If the pressure switch (oil pressure switch in the single tank generator) is active in Siemens Medical Equipment, it may indicate that the tube is overheated. Also, measure D915 plug X8 at pin 8; a measurement of 0V indicates a malfunction.
