4) make an exposure, then the following will appear:
70 kV 14 mA
5) at the end of the third exposure, the Vf Tube Editing
program is automatically entered, showing the tube
calibration parameters obtained at the end of the tube
calibration; take note that these parameters are already
6) record the values in the System Configuration Module (See
Section C)
7) press the DUMMY RUN key on the keyboard to leave the
Vf Tube Editing service program.
For more information concerning the tube calibration, refer to the
paragraph Adjusting tube current of this section of the Service
Manual.

4.3.26.Console test.

With this service program you can start a test of the keyboard and
of the display.
The following message will appear on the display:
CONSOLE TESTS
Press DUMMY RUN to go.
After pressing the DUMMY RUN key on the keyboard, the following
message will appear on the display:
CONSOLE TESTS
keys to press 20
The first part of the test is a check on every key of the keyboard:
when a key is pressed, the relevant LED indicator (if present)
turns on and decrements the counter of the key, which must be
pressed again.
The counter starts from 20, because there are 20 keys on the
keyboard and every key is recognized only at the first pressure
(so if a key is pressed more than once, the counter does not
decrement).
Every time a key is pressed an audible message ("beep") is
generated.
When all the keys have been pressed, an automatic display test
starts, showing all the ASCII characters (letters, numbers and
special symbols).
At the end, it automatically enters the selection of the service
programs and turns off all the LEDs on the keyboard.

4.3.27.Retry readout

In case of detection of a protocol error in the communication among
the electronics board, several alarms are generated; they are:
Converter: Link failure when the host computer board PC1 has
detected a communication error with the converter board
PQ1
Conv. link fail 2 when the converter board PQ1 has detected a
communication error with the host computer board PC1
Console: link failure when the host computer board PC1 has
detected a communication error with the operator conso
le control board PC7
No communication when the operator console control board PC7
has detected a communication error with the host compu
ter board PC1
PA5 board link failure when the host computer board PC1 has
detected a communication error with the PA5 AEC control
board.
DENTSPLY Gendex
0.5 s
(03.0)E
..............................................................................
These alarms are generated if after three attempts (retry) of
communication, the proper communication protocol is not restored.
There are two software counters associated to each board (PQ1,
PC7 and PA5) that are counting the communication faults occurred:
with the Retry readout service program it is possible to check the
contents of these software counters.
The following message will appear on the display:
RETRY READOUT
DUMMY RUN TO GO
By pressing the DUMMY RUN key on the keyboard, the following
message will appear:
RETRY READOUT
PQ1 X zz nX yy
where:
PQ1 = this means that the two software counters are related to
the converter board PQ1
X = communication errors during the X-ray cycle
z z = number of communication errors occurred during the X-
ray cycle
nX = communication errors out from the X-ray cycle
y y = number of communication errors occurred out from the
X-ray cycle
By pressing the mA+ or kV+ or s+ keys on the keyboard, it is
possible to check the counters associated to the PC7 and to the
PA5 boards.
The following messages will appear on the display:
RETRY READOUT
PC7 X zz nX yy
for the operator console control board PC7, and:
RETRY READOUT
PA5 X zz nX yy
for the PA5 AEC control board.
With the mA- or kV- or s- it is possible to select the software
counters related to the previous board.
At the end of the boards sequence, a reset option will be selected,
to reset all the software counters; on the display will appear the
following message:
RETRY READOUT
RESET OR <DRUN>
If the RESET key on the keyboard is now pressed, all the software
counters are reset and the Retry readout service program is
automatically ended.
If the DUMMY RUN key on the keyboard is now pressed, the Retry
readout service program is automatically ended and all the software
counters are not reset.
