Shenzhen Angell Technology Co., Ltd Service manual
4.2 Troubleshooting
For all the faults in the above list, the fault search is as follows:
4.2.1 E20 fault First gear signal fault of the hand brake
52 / 111
Shenzhen Angell Technology Co., Ltd Service manual
The fault is that the first gear signal of high voltage generator is always present. It is necessary to open
the front panel of the whole machine, release the hand brake, and observe whether the signal indicator
D309 of the whole machine control board is always on. If it is always on, it means that there is a problem
with the main control gear signal and you need to find the fault of the main control board.
4.2.3 E14 fault There is no second gear (5s) for a long time after the first hand brake.
The fault is that when the first gear signal of the hand brake is pressed, the second gear signal of the
hand brake is not received within 5 seconds, open the front panel of the machine, press the emergency
stop switch, use the limited hand brake, and press the first gear and the second gear signals at the
same time, observe whether the indicator lights D310 and D309 on the control panel of the whole
machine will light up. By default, when the first and second gear signals are pressed at the same time,
the indicator light D309 will light up immediately, and D310 will be lit after D309 lights up for 2 seconds
on, if the D310 has not been lit, it means that the main control board is faulty. If it is normally lit, continue
to check whether the high voltage generator exposure signal line has poor contact or the line sequence
is wrong.
Exposure time-out, the fault is caused by abnormal sampling of the tube current, first observe whether
the CX3 connection in the terminal of the high voltage control board is abnormal, as shown in Figure 4-
1:
53 / 111

Inverter current

sampling
CX8terminal
CX8
No mAs integration indicates that there is an abnormality in the tube current sampling, and the
processing method is the same as 4.
+mA and -mA overload, there are two common causes of this failure, which are the loss of tube
54 / 111
Shenzhen Angell Technology Co., Ltd Service manual
calibration data and abnormal ignition of the tube; first determine whether the failure is due to the loss
of tube calibration data, open high-voltage debugging tools, as shown in Figure 6-1:
In the mode switch, click the radiography setting mode and observe whether the value of MAST is
500. If it is 500, it means that the tube calibration data is lost, and the tube calibration data needs
to be input again.
In the first step, it is judged that the calibration data of the tube exists, it is possible that the tube is
sparked and the fault occurs. The operation will be performed, the KV value in the shooting
parameters is adjusted to 40KV, the tube current is adjusted to 50mA, mAs parameter is adjusted
to 1mAs, exposure again, and observe whether the fault still exists. If the fault disappears, it can be
judged that the tube has caught fire; if the fault still exists, the high-voltage main control board needs
to be replaced.
The fault is that the positive and negative KV deviation is too large. The cause of this failure is the failure
of the oil tank, which requires replacement of the high-voltage oil tank.
4.2.9 E23 Inverter current without feedback and E24 tank sampling without feedback
55 / 111
Shenzhen Angell Technology Co., Ltd Service manual
Inverter current without feedback and oil tank sampling without feedback are handled in the same way
as item 4. Among them, if there is no feedback of the inverter current., it is necessary to judge whether
the CX8 terminal in Figure 4-1 is in good contact, and the CX8 terminal can be inserted and removed
again.
The fault is due to overcurrent of the filament, which is protected by overcurrent. The tube current can
be reduced to a minimum value of 50mA, and an exposure test can be conducted to observe whether
the fault exists. If the fault exists, the filament board may be abnormal and the filament board needs to
be replaced.
The fault is because the bulb has been working for a long time, which leads to the over-temperature
protection inside the bulb. Let the whole machine stop working for a while, test again and observe
whether the fault exists.
4.2.12 E11 RIT, anode current abnormality and E12 RVT anode voltage abnormality
The cause of the failure is due to the failure of the rotating anode board, and the rotating anode board
needs to be replaced directly.
