9.7.5 Checking the connection of the MS and FH (pan) laser
light localizers
NOTE: The cables/plugs of the laser light localizers are not labeled ex
works. Should the sockets for plugs X607 (MS) and X611 (FH) get mixed
up on board DX1, there will be a control error in the 3D design of the
ORTHOPHOS SL X-ray unit.
In order to check whether the plugs of the MS and FH laser light localizers
are plugged into the correct sockets on the DX1 board, complete the
following steps:
1. Switch the unit on via the switch (A) (see also Operating Instructions).
B
C
2. Touch the 3D symbol at the top of the touchscreen.
3. Press the R key.
4. Press the light localizer key on the control panel.
The X-ray radiation indicator (B) lights up briefly.
After approx. 2 seconds, the green LED (C) in the upper part of
the control panel lights up. This LED remains lit as long as the
unit is on.
The start screen appears on the touchscreen of the Easypad and
the system's self-adjustment routine starts running (for approx. 1
minute). The diaphragm moves into position. Forehead and
temple supports on the panoramic unit are moved to the home
position.
On completion of the self-adjustment routine, the main menu
appears on the touchscreen. Help message H301 prompts you to
move the unit into the starting position.
The 3D program group is selected.
The diaphragm and the sensor move into the starting position for
3D exposures.
Two horizontal laser lines from the laser area display and a
vertical laser line from the MS laser light localizer should be
displayed on the sensor unit cover (side of the flat panel
detector).
There must not be a third horizontal laser line from the FH laser
module shown in the 3D programs.
If a third vertical laser line is shown on the sensor unit cover
(instead of the horizontal laser line), swap the connections of
plugs X607 and X611 and repeat the test in the 3D program
group once more.
