2.14
Error Code: E.15
Meaning
Tube voltage immediately before termination of exposure was higher than 70 kV (when 60 kV is set) or 80 kV
(when 70 kV is set).
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 voltage.
①
After exposure, do not release the exposure switch. Press the kV 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 less than 70 kV (when 60 kV is set) or not less than 80 kV (when 70 kV is
set), decrease the setting value for CP.X. (Refer to section 3.3.)
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.15) 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.
2.15
Error Code: E.16
Meaning
Tube voltage during exposure dropped to less than 40 kV (when 60 kV is set) or less than 50 kV (when 70 kV
is set).
To release
Turn off the main power switch and confirm all displays go off. Then turn on again.
Verification
The arm cable (main output line) may be broken. Disconnect the arm cable from the head (10P connector)
and the power PC board (2P connector) and check continuity of the cable.
1. between #10 (head side) and #1 (power PC board side)
2. between #5 (head side) and #2 (power PC board side)
Solution
Replace the arm in question (horizontal or balance arm) if any failure is found.
If not resolved
Possible cause 1
The arm cable (tube voltage feedback line) is broken.
Verification
Disconnect the arm cable from the head (10P connector) and the power PC board (8P connector) and
check continuity between #7 (head side) and #6 (power PC board side).
Solution
Replace the arm in question (horizontal or balance arm) if any failure is found.
Possible cause 2
The power PC board or the head is out of order.
Verification
Replace the head and check whether the same symptom (Error code E.16) appears again.
Solution
If the same symptom appears, the cause of the error is presumed to lie in the power PC board and it
should be replaced. If the exposure turns out to be normal, the cause is presumed to lie in the head.
