Chapter C - HELP & ERROR MESSAGES
C-8 Planmeca Proline CC panoramic x-ray
Technical Manual
- 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 (CEPH units only).
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 square incisor light is not on, the sensor magnet must be adjusted.
If the square incisor 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 (CEPH units only).
The secondary slot has moved with the soft tissue filter. This would cause the beam to be atten-
uated and possibly cause the patients nose to be cut of film when making a lateral CEPH expo-
sure.
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 position
mechanism from its place and file the holes in front of the mechanism so that the mechanism can
be positioned back enough.
Er 45 The soft tissue filter position not calibrated
The soft tissue filter position must be calibrated. If not, this error is indicated.
Perform the calibration according to instructions given in section “Soft tissue filter positioning light
calibration and adjustment” on page D-40.
3.7 Errors 50-57 (connector or cable errors)
Er 50 Temperature sensor shorted
Before each exposure and after pressing READY or kV, mA adjustments the temperature of the
tube head is measured. If the result is too low it is assumed that the sensor is short circuiting.
Sensor broken. Measure the resistance that should be 1000 ohms at 25 °C. If not near, replace.
If disconnecting the cable to cassette end limit sensor board cures this error, then this cable and/
or sensor board is partially shorting the + 15V.
Check in service mode the measured temperature. If still low with cables disconnected, faulty
generator processor board.
Er 51 Temperature sensor open (overpressure when applicable)
Before each exposure and after pressing READY or kV, mA adjustments the temperature of the
tube head is measured. If the result is too high it is assumed that the sensor is open circuit. In
some models there is an overpressure sensor in the tube head, connected in series with the tem-
perature sensor and breaking the circuit at overpressure. Also, if the tube head and generator
processor grounds are not properly connected to the protective earth this error will be indicated.
Check the earthing cables.
If seems ok by resistance measurement (about 1000 ohms at 25°C) then the generator proces-
sor board is faulty.
