Replace the arm in question (horizontal or balance arm) if any failure is found.
Possible cause 3
If seven segment LED displays not more than 1 mA, the power PC board or the head is out of order.
Solution
1. Both the power PC board and x-ray head should be changed, if the manufactured date is Oct. 2005 or
earlier.
2. X-ray head should be changed if the manufactured date is Nov. 2005 or later. If the tube current is
not more than 1 mA after the head is replaced, change the power PC board, too.
Possible cause 4
If seven segment LED displays more than 1 mA, but not more than 1.9 mA (when 4 mA is set) or not more
than 3.4 mA (when 7 mA is set), tube current might be low at transient period of exposure.
Solution
1. Both the power PC board and x-ray head should be changed, if the manufactured date is Oct. 2005 or
earlier.
2. X-ray head should be changed if the manufactured date is Nov. 2005 or later.
2.8
Error Code: E.08
Meaning
Tube current during exposure rose to 15 mA or above.
To release
Turn off the main power switch and confirm all displays go off. Then turn on again.
Verification
Make exposures for 0.1 seconds and check whether the same symptom appears every time.
Solution
Decrease the setting value for h.XX. (Refer to section 3.5.)
If not resolved
Possible cause
The power PC board or the head is out of order.
Verification
Replace the head and check whether the same symptom (Error code E.08) appears again.
Solution
If the same symptom appears, the cause of the error is presumed to lie in the power PC board. In this case,
replace the power PC board. If the exposure turns out to be normal, the cause is presumed to lie in the
head.
2.9
Error Code: E.09
Meaning
The set value for the preheating power is abnormal when the power is turned on.
To release
Turn off the main power switch and confirm all displays go off. Then turn on again.
Solution
Set the h.XX value to “h.10” at all conditions (60 kV/4 mA, 70 kV/4 mA, 60 kV/7 mA, 70 kV/7 mA). If the
same symptom (E.09) does not appear when the power is turned on again, set the CP value (see 3.3) and
perform automatic adjustment of preheating power (see 3.6).
If not resolved
Possible cause
The timer PC board (EEPROM) is out of order.
Verification
Replace the timer PC board and check whether the same symptom (Error code E.09) appears again.
Solution
If the error code disappears, the timer PC board is presumed to be the cause. Replace it.
