In this case reset the unit and repeat the ceph positioning
2. Check that the ceph sensor position is mechanically stable, if it is not call
the AS
3. When the sensor is in ceph position, check that the Hall sensor B13 can
reach the magnet positioned on the 3D sensor rotating shaft. Check also
that the magnet is present and stable.
Test with the multimeter on connector X79-pin4 and GND X79-6 (A12),
MUST BE 0V when sensor is in ceph position and> 3V when in other
positions
4. Check that the B13 hall sensor signal is correctly connected to the CCU
board through the following connection chain: X79 connector-> A12
collimator board-> cable X77-X59 pins 4->CCU board.

E603 The chin rest must be removed in order to start exam
Remove the chin rest from the unit in order to prepare the unit to perform the
exam.
9.2.6.4
E604 Flat Panel is open, but should be closed
This error is shown when the Flat Panel sensor is not closed in 3D/pan position while
the unit is in a panoramic, 3D or static image status.
Checks:
1. Check that the sensor has not intentionally been opened by the operator. In
this case reset the unit and repeat the exam.
2. Check that the ceph sensor position is mechanically stable, if it isn’t call the
AS
3. When the sensor is in 3D/pan position, check that the Hall sensor B12 can
reach the magnet positioned on the 3D sensor rotating shaft. Check also
that the magnet is present and test with the multimeter on connector X79-
pin3 and GND X79-5 (A12), MUST BE 0V when sensor is in pan3D position
and> 3V when in other positions
4. Check that the B12 hall sensor signal is correctly connected to the CCU board
through the following connection chain: X79 connector->A12 collimator
board->cable X77-X59 pins 2->CCU board.
9.2.6.5
E605 A time out error occurred durin CCU motors movement
This error is shown in case the CCU doesn’t communicate the end of an axis
movement to the MCU within the time out limit
Checks:
Switch off-on the unit, when the green led blinks press the >O< button and
verify that during the axis reset the following axis, driven by CCU board,
moves correctly:
- Primary collimator
- Secondary collimator
