If still there is no motion, replace the stepper motor and, if not fixed,
replace the CPU.
If a motion has been observed, but messages are displayed, this can be
the sensor or its wiring.
Power off the system and try to manually disengage the sensor, taking
care of a smooth motion.
Power on the system and check the functioning of the sensor,
measuring the DC voltage on the terminal of the sensor B8, with and
without an obstacle manually inserted. A variation of about 3.5 V
minimum should be observed. If not, replace the sensor.
If the variation is observed and the message still continues to be
displayed, check the correct insertion of the cable from the sensor B8
to X58 and from that connector to X31 of the main CPU A5; check
continuity of the interested wires and replace the faulty one (if any).
If all cables are OK, the fault is on the CPU, so replace it.
8.2.3.3.
E340: Sensor holder not in PAN position
An examination requiring the sensor holder in PAN position has been
selected, but it is not sensed in the proper position.
Close the PAN sensor holder to its position and press the Patient
centering key to restart the power on procedure.
If this does not reset the error message:
Check the proper function of optical sensor B6.
Check continuity of cables from optical sensor to board A8, connector
X48, and from that board to main CPU board (A5), connector X33.
