7-2.16 F62
In 1 sec after HX1 is input, XOK is not sent back. This message is not displayed usually.
Confirm the setting of the DIP switch.
7-2.17 F6d
Emergency status.
Check emergency circuit.
7-2.18 F6E
Exposure did not terminate even by the preset timing or mAs setting.
The X CONT-2002 PCB (X-ray cutoff circuit) may be abnormal.
7-2.19 F6F
The exposure control circuit is abnormal.
In 250 msec after the EXR is sent out, the KVT (kV rising signal) is not sent back.
X CONT-2002 PCB may be defective.
7-2.20 D1
Over current is detected. Motor current is detected as more than 6A for more 10sec .
One of the left and right DC Motors is defective.
Motor current can be checked at CP9 (for Left Motor) and CP10 (for Right Motor) on MU
DRIVER-2 PCB.
The OFFSET voltage at both check pins is 2.5V when DC Motor is not driven.
The relation is 0.1V/0.67A. So, the error D1 normally happens when the voltage at the above
check pins exceeds about 3.5V.
By checking the voltage at both check pins, judge which DC Motor is defective.
If the voltage at both check pins are normal, MU DRIVER-2 PCB or XCONT 2002 PCB may be
defective. However, there is still possibility that one of DC Motors is defective.
7-2.21 D3
Abnormal encoder of DC Motor is detected.
The function of the encoders of left and right DC Motors can be checked according to Appendix
B.11 of Installation Manual.
By using this checking mode, judge which DC Motor is defective.
If cable connection between the encoders and MU DRIVER-2 PCB is no problem, replace the
defective DC Motor.
If both of DC Motors are no problem, MU DRIVER-2 PCB may be defective.
