ERROR MESSAGE EXPLANATIONS
Technical Manual
3.5 Errors 40-44 (mechanical errors)
Er 40 Rotation remains short
At the end of the panoramic exposure the rotation end sensor must be reached. If not, this
error is indicated.
- Friction drive slipping (surfaces, motor spring)
- Inoperative sensor
- Sensor misplaced
- Check in service mode and adjust if necessary
Er 41 Rotation too long
At the end of the panoramic exposure the rotation must not go over the end sensor. If so, the
operation is stopped with this error indication.
- Friction drive slipping forward (centering spring drawing it to this forward direction)
- Inoperative sensor (giving pulses, not good signal)
- Check in service mode and adjust if necessary
ER 42 Secondary slot not locked
The secondary slot was not locked into position.
After returning from CEPH mode, the secondary slot did not engage with the slot on the top of
the secondary slot. Return the unit to the CEPH mode and then back to PAN mode.
Enter the service mode. If the sector A indicator light is not on, the sensor magnet must be
adjusted. If the sector A indicator light is on, the solenoid needs to be adjusted.
Er 43 Secondary slot out of position
The secondary slot is out of position in CEPH mode.
The secondary slot has moved with the soft tissue filter. This would cause the beam to be
attenuated and possibly cause the patients nose to be cut of film when making a lateral CEPH
exposure.
The magnet that hold the secondary slot in position or the sensor needs adjustment. Probably
both.
Er 44 The patient positioning mechanism zero point set incorrectly
The patient positioning mechanism can not reach the -24 position.
Loosen the patient positioning mechanism screws and move the mechanism backwards. Try
to calibrate the mechanism again. If the position -24 is not reached, remove the patient posi-
tion mechanism from its place and file the holes in front of the mechanism so that the mecha-
nism can be positioned back enough.
