F.3.8 Fault opto film
This alarm message is always related to the optoswitch S16 that
carriage, as the alarm Cassette (see the description in this sec-
tion of the Service Manual) but it indicates that the optoswitch
is broken.
Press the RESET pushbutton on the control panel to cancel the
alarm.
F.3.9 Collimator
The position of the collimator is detected by three optoswitches
(S21,S22 and S30) as listed in the table below:
S21 S22 S30
ON ON ON
ON ON OFF
ON OFF ON
ON OFF OFF
OFF ON ON
OFF ON OFF
OFF OFF ON
OFF OFF OFF
This alarm is generated when the collimator is in an intermediate
position, i.e. between transcan and panoramic, while it is moved
to change its position according to the projection desired (pan-
oramic, transcan, teleradiography).
When the correct position is reached, the alarm is automatically
reset.
The alarm is also generated if the collimator is in the transcan
position but the transcan option is not present in the system.
If the alarm stays on it may mean:
1.
one of the collimator optoswitches S21, S22, S30 is damaged
(see principle diagram Z1-11)
2.
damaged (see principle diagram Z1-11)
3.
If the converter board PQ1 needs to be replaced,
the service programs Tube calibration and Vf tube
editing must be performed (see the relevant para-
graphs of this section for more information).
