For older or similar systems, the Multimobil 5C service manual is archived on the Internet Archive (published/updated April 2021) . Key Technical Specifications (Multimobil 5E) Specification Mains Voltage 190 – 240VAC Power Output 2.5 kW @ 100kV (Radiography) Generator High Frequency for both Fluoroscopy and Radiography KV Range 40 – 100kV (often in 20 steps) Monitor Distortion-free TFT monitor Filtration 5.3 mm Al at 100kV (standard for similar series) Installation & Maintenance Notes
Compare the measured output with the digital reading. Adjust the corresponding potentiometers on the main generator board until the value falls within Repeat the process for high-kV ranges (up to 125 kV). Dose Area Product (DAP) Meter Calibration (If Equipped)
Inspect the physical 2-step exposure release switch and its cable connections. Use a digital multimeter to check continuity across both contact steps.

Select the low-kV calibration option (typically 40 kV) and trigger a test exposure.
| Error Code | Display Message | Most Common Cause (2021 data) | Fix per Service Manual | |------------|----------------|-------------------------------|------------------------| | | HV generator timeout | Aging C39 capacitor on inverter control board (value drifts >10%) | Replace C39 with revised 105°C-rated 22µF/450V capacitor (Siemens PN: 82-145-67) | | E-788 | Image intensifier gain instability | Photocathode voltage supply ripple >1.5V p-p | Run automatic gain calibration (Service menu > System > II Cal). If fails, replace HV supply module. | | E-102 | Column motor overcurrent | Brake magnet coil shorted (worn insulation) | Measure resistance between pins 3-4 on brake connector – should be 220Ω ±5%. Replace brake assembly if out of spec. |
2V). Voltage fluctuations outside this range can introduce visual noise or cause intermittent video loss. Mandatory Radiation Safety and Preventive Maintenance Dose Area Product (DAP) Meter Calibration (If Equipped)
Ensuring beam alignment, filtration, and shielding are within compliance.
Adjust the potentiometer trims on the main generator control PCB or adjust the digital DAC values until the measured output is within of the selected value.
Routine service is vital for hospital compliance and equipment longevity. Standard protocols for similar Siemens mobile units often include:
Understanding the internal electrical and radiological thresholds is crucial before performing any maintenance work. The system architecture balances powerful radiography with fine-tuned fluoroscopy.
