C-6 Planmeca Proline CC panoramic x-ray
If this motor runs more than 30 seconds continuously this time out error is generated and all
action is stopped.
Motor or cables broken if motor is not running
If keyboard button was operated all the time the reason is either that the layer motor cable is bro-
ken (no movement or sound) or the carriage is jammed (loud sound can be heard). If the carriage
was moving but never stopped on the end limits the limit sensor is inoperative. Check sensor
operation in service mode. End limits do not stop the motor in service mode, be careful not to
break the mechanism!
If the motor was running while the keyboard was not operated and no buttons operate, defective
keyboard.
If this motor runs more than 30 seconds continuously this time out error is generated and all
action is stopped.
Motor or cables broken if motor is not running
The calibration sensor is inoperative. Check in service mode. Note that the sensor operating volt-
age is on only when the calibration sequence is performed in order to avoid aging of the sensor.
In service mode the voltage is continuously on.
If this motor runs more than 30 seconds continuously this time out error is generated and all
action is stopped.
Motor or cables broken if motor is not running.
The end limit detector(s) are inoperative or misplaced. Check in service mode. The sensor mag-
nets should be placed in such a positions that it is not possible to move the cassette over the lim-
its. Check both the cassette holder and the holder carriage limits.
If this motor runs more than 30 seconds continuously this time out error is generated and all
action is stopped.
Motor or cables broken if motor is not running.
The start position sensor is inoperative or the rotating arm has been pushed over to wrong side
of the limit sensor. Check in service mode and/or push the arm towards center.
Check that the friction drive is not slipping.
If this motor runs more than 25 seconds continuously this time out error is generated and all
action is stopped. Check that the movement is not obstructed.
Limit sensor cable is loose or broken.
Motor or cables broken if motor is not running.
If this motor runs more than 10 seconds continuously this time out error is generated and all
action is stopped.
The wrongly installed Frankfort light or a cable prevents the sensor head from reaching the pan-
oramic position.
The safety limit switch is pressed and the movement of the sensor head is prevented.
