Safety Protection Device and Troubleshooting
7-2
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 system error occurs, the failure indicator on the console is on, and the error code
will be displayed on the kV display window of the console. The failure description for the
error cods are listed in Table 7-1 below.

E02 Panel key stuck failure
Press each key on the panel, and make
sure each key bounce back properly.
E04
Press Fn to clear the code. If the error
still exists, restart the system after it is
cooled.
The hand switch is released ahead
of time during exposure
Press Fn to clear the code.
H06
Detector exposure sync failure
Press Fn to clear the code. Check if the
connection to the detector is loose.
Confirm if the correct detector model is
selected (engineering mode P8).
H07
Exposure hand switch Level 1 was
pressed down upon bootup
detection
Press Fn to clear the code. If the error
still exists, replace the exposure hand
switch.
H08
Exposure hand switch Level 2 was
pressed down upon bootup
detection
Press Fn to clear the code. If the error
still exists, replace the exposure hand
switch.
