What does Imax mean on Siemens Medical Equipment?
If 'Imax' is displayed on the Siemens Medical Equipment, it indicates the tube or filament current is recorded. Check the filament circuit and verify if the exposure filament basic value is incorrectly set (P5 on D915). Also, check for tube arcing. If kVact < kVnom, Err 14 or Err 13 may be detected and displayed.
What does KVmax - Interruption of KVact measurement mean for Siemens equipment?
If the Siemens Medical Equipment displays 'KVmax - Interruption of KVact measurement', measure TP ’KVN’ and ’KVP’ on D915 to ensure both signals have the same amplitude. Also, check if ’KVN’ or ’KVP’ exceeds 70 kV and investigate for errors in the kV measurement or control circuit.
How to fix capacitor charge error in Siemens Medical Equipment?
If the capacitor charge error occurs after switching the Siemens Medical Equipment off and back on again, configure the capacitor bank. Other possible solutions include checking if the discharge resistors are permanently connected, verifying if the temperature sensor on D950 has responded, checking for overvoltage in the C-bank (D950 TP ’VC’), and determining if there is a short on D950, replacing it if necessary. The error may occur because the system has not been used for a longer period of time, leading to higher capacitor leakage current.
What causes Rot = 0 (rotating anode speed is 0 on exposure) in Siemens equipment?
If 'Rot = 0' (rotating anode speed is 0 on exposure) on your Siemens Medical Equipment, check if the LED ’AR’ on D925 flashes and ensure fuse F5 is ok. Measure at TP ’I1’ and ’I2’ to confirm current is present during acceleration. Also, check D925, verify if the power factor correction capacitor C2 is defective, and ensure the connection to/in the single tank generator is secure.
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.
What causes Vfil > Vstby (filament current is too high) in Siemens POLYMOBIL Plus?
If the Siemens Medical Equipment displays 'Vfil > Vstby' (filament current is too high), check if ’V1’ (-DC) and ’V2’ (+DC) flash on D925; if not, check fuse F6. Also, determine if the filament frequency is too high. If the A/D converter on D915 is defective, replace D915. Check for a short-circuit at the output of the filament inverter, inspecting the connection to/in the X-ray tube assembly.
How to troubleshoot Vfil < Vstby (none or insufficient filament current) on Siemens equipment?
To troubleshoot 'Vfil < Vstby' (none or insufficient filament current) on Siemens Medical Equipment, first check if ’V1’ (-DC) and ’V2’ (+DC) flash on D925; if not, check fuse F6. Also, check D915 for filament frequency, ensure the connection D925 to the X-ray tube unit (X5) is secure, verify the connection D925 to D915 (X11), inspect the X-ray tube assembly, and consider that D925 may be defective.
What causes braking failure in Siemens POLYMOBIL Plus Medical Equipment and how to fix it?
If the Siemens Medical Equipment experiences braking failure, check D915TP ’I1’ to ensure no current is measured during braking and verify that braking current is measured at D915 TP ’I2’. If either TRIAC ’V7’ or ’V8’ is defective, replace D925.
What does EPROM checksum error mean on Siemens POLYMOBIL Plus Medical Equipment?
If the Siemens Medical Equipment displays an EPROM checksum error, it indicates that the EPROM 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.
