2.16
Error Code: E.17
Meaning
Tube voltage during exposure rose to 80 kV or above.
To release
Turn off the main power switch and confirm all displays go off. Then turn on again.
Solution
If the same symptom appears, it is more likely that the power PC board is the cause. In this case, replace the
PC board.
If not resolved
Possible cause
The head is out of order.
Solution
Replace the head.
2.17
Error Code: E.19
Meaning
An over current ran the primary circuit of the high voltage transformer.
To release
Turn off the main power switch and confirm all displays go off. Then turn on again.
Solution
If the same symptom appears, it is more likely that the power PC board is the cause. In this case, replace the
PC board.
If not resolved
Possible cause
The head is out of order.
Solution
Replace the head.
2.18
Error Code: E.20
Meaning
The exposure switch was pressed when the temperature inside the head was 60
℃
or higher.
To release
Release the exposure switch to restore the original state.
Solution
It is highly likely that exposures were conducted irrespective of the duties, and the temperature inside the head
rose to 60
℃
or higher. Explain that the operator must wait until the temperature drops (until the ready light
becomes on) before the next exposure.
If not resolved
Possible cause 1
The arm cable (temperature sensor line) is broken.
Verification
Disconnect the arm cable from the head (10P connector) and the power PC board (8P connector) and
check continuity of #6 (head side) and #5 (power PC board side).
Solution
Replace the arm in question (horizontal or balance arm) if any failure is found.
Possible cause 2
The arm cable (signal common line) is broken.
Verification
Disconnect the arm cable from the head (10P connector) and the power PC board (8P connector) and
check the continuity between #2 (head side) and #3 (power PC board side).
Solution
