7.4 Failure Analysis and Troubleshooting
Failure Diagnosis
The device has a failure self-test function. If any key failure occurs, the device will give
alarm, which facilitates failure inspection and troubleshooting.
Generally, the first step to confirm a failure is to check if the voltage of the power supply
is normal, and check all circuit boards for any failure.
Key points to determine failures
If any device error occurs, the component failed can be determined from the displayed
error. Check the test points of the relevant components and signal indicators to quickly
determine the cause of failure, so as to restore the device to normal in time.
Error message
When a system error occurs, the portable X-ray unit sounds "di- di" and an error message
is displayed on the control panel. The corresponding content and troubleshooting of the
error prompts are described in Table 7-1.
