Technical Manual
3.4 Exposure counter display
In the service mode it is possible to verify the amount of exposures taken. There are three
counters in the system, one counting the normal panoramic exposures, one counting the cepha-
lostatic exposures and one counting every exposure (also the ones made in the service mode).
Exposures that caused an error and were interrupted are not counted. When one of the counters
is wanted to be seen, after the right key sequence the counter is displayed in the main display for
a few seconds after which the normal temperature display reappears. The key sequence always
needs to be started with the CTL-key to get the indicator light on and the second key determines,
which counter is displayed.
Because the main display has only four numbers on it and is therefore capable of showing counts
only up to 9999 a special method has been provided to be able to display counts up to 49 999.
The two dots between the numbers indicate the amount of 10 000 to be added to the displayed
number as follows:
Lower dot on Add 10 000
Upper dot also on Add 20 000
Lower dot blinking Add 30 000
Upper dot also blinking Add 40 000
When 50 000 exposures has been taken the counter is cleared to zero and starts to count the
next 50 000.
3.5 Error history display
In order to make the equipment failure analysis easier an error history display has been provided.
This error memory contains the 50 last errors occurred (not Er 00). The stack depth is not neces-
sarily 50, if less errors have occurred. In this case only the amount of errors that have happened
is displayed.
Press the CTL-key and the return key to enter this mode. The last error occurred (-01) is shown.
If no errors were memorized the displays appear blank. In this mode all the indicator lights are
undetermined and the numeric displays have a different function as is explained in the following:
PRIMARY SLOT DISPLAY Blinking E to indicate Error display mode
kV-DISPLAY Day of month when error occurred
mA-DISPLAY Month when error occurred
MAIN DISPLAY Hours and minutes when error occurred
EXPOSURE TIME DISPLAY Error code number that occurred
mm-DISPLAY Running number of this error in the stack (-01 - -50)
In this mode the keys READY, UP and DOWN only are operative. The functions of these keys
are:
UP Find next error (newer one, towards -01)
DOWN Find previous error (elder one, towards -50)
READY Exit to service mode
