  • Page 5: Error Code: E.01

    3.2 Error Code: E.01 Meaning The exposure switch was pressed within three seconds after power-on. The exposure switch was pressed within ten seconds after previous exposure. To release Release the exposure switch to restore the original state. Solution Explain that the operator must wait to press the exposure switch for three seconds after power-on (until the ready light is on) and that exposure is allowed only after an interval 30 times the length of the last exposure time.

  • Page 6: Error Code: E.05

    Solution Decrease the voltage using a step-down transformer if the supply voltage is more than 110% of the rated voltage. If not resolved (or if the line voltage is within the range of ±10% of rated voltage.) Possible cause The memory is out of order. Verification Check C.XX setting at overview mode.

  • Page 7: Error Code: E.07

    more than 7.5 mA (when 6 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. ①After exposure, do not release the exposure switch. Press the mA button twice while holding down the exposure switch.

  • Page 8: Error Code: E.08

    Disconnect the arm cable from the head (10P connector) and the power PC board (8P connector) and check continuity of the cable. 1. between #4 (head side) and #4 (power PC board side) 2. between #8 (head side) and #7 (power PC board side) 3.

  • Page 9: Error Code: E.09

    3.9 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/3 mA, 70 kV/3 mA, 60 kV/6 mA, 70 kV/6 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).

  • Page 10: Error Code: E.14

    There is a failure in the power PC board. Replace the PC board. 3.13 Error Code: E.14 Meaning Tube voltage immediately before termination of exposure was less than 50 kV (when 60 kV is set) or less than 60 kV (when 70 kV is set). To release Turn off the main power switch and confirm all displays go off.

  • Page 11: Error Code: E.16

    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.

  • Page 12: Error Code: E.19

    Solution Replace the head. 3.17 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.

    terminals in the head connector. Solution Replace the head if no continuity between #2 and #6 terminals is confirmed. 3.19 Error Code: E.22 Meaning Communication between the power PC board and the timer PC board was not normal. To release Turn off the main power switch and confirm all displays go off.
  • Page 14 Replace the fuse if it has been blown.. If not resolved Possible cause 1 The communication cable (power line) is broken. * If the fuse blows again when fuse is replaced, no break exists in the communication cable. Verification Check continuity of the #1 and #4 wires of the communication cable. Solution Replace the communication cable if any failure is found.
