⑤
Check that the calculation result of b - (a x 0.03) falls within
±
0.05 V.
Solution (See photo 1)
Adjust VR01 on the PC board to make b = (a x 0.03).
Possible cause 2
The memory is out of order.
Verification
Check C.XX setting at overview mode. (Refer to section 3.9.)
Solution
If C.7F is displayed, memory is out of order and timer PC board should be replaced.
2.5
Error Code: E.05
Meaning
Tube current immediately before termination of exposure was less than 3 mA (when 4 mA is selected) or less
than 5.25 mA (when 7 mA is selected).
To release
Turn off the main power switch and confirm all displays go off. Then turn on again.
Verification
Make an exposure for 0.05 seconds and check the tube current.
①
After exposure, do not release the exposure switch. Press the mA button twice while holding down the
exposure switch.
②
Keep holding down the exposure switch and check that the T5 light is on and the indication of the
seven-segment LED.
Solution
If seven-segment LED displays not more than 2.9 mA (when 4 mA is set) or not more than 5.2 mA (when 7
mA is set), increase the setting value for h.XX. (Refer to section 3.5.)
If not resolved
Possible cause 1
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 2
If seven segment LED displays more than 1 mA, but not more than 2.9 mA (when 4 mA is set) or not more
than 5.2 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.
Possible cause 3
The tube current adjusting value is not properly adjusted.
Solution
Increase the setting value for EP.X. (Refer to section 3.2.)
2.6
Error Code: E.06
Meaning
Tube current immediately before termination of exposure was more than 5 mA (when 4 mA is selected) or
more than 8.75 mA (when 7 mA is selected).
To release
Turn off the main power switch and confirm all displays go off. Then turn on again.
Verification
Make an exposure for 0.05 seconds and check the tube current.
