E755: Alarm “Backup timer intervention” /
E758: Alarm “No X-ray” /
E759: Alarm “unexpected emission”

The correctness of X-ray emission is checked by the Generator board
(A10) measuring the anodic current against the set nominal value. When
the system is in the idle mode, that is in a non emitting state, this signal
must be low, and the Generator CPU board (A9) is checking this
condition. If this does not happen, the E759 message is displayed.

When the CPU command for the emission, the X-ray on signal is set to on
condition when it reaches the 75% of its set value at the beginning and is
higher than 25% at the end of emission.
If the first condition is not met, the exam is halted and the system has to
be reset, and the

message E758

"No X-ray"

is displayed.

In this case, check the correct insertions of X56 and X57 between the
Generator board to the tubehead and X53-X53 (flat cable) between
Generator board and Generator CPU board (A9).
Check the CANBus connection between the Generator CPU board (A9)
and the main CPU A5 (cable X20-X20).
If all connections are OK and the fault is repetitive, replace the tubehead.

If the second condition is not met, that is, the X-ray emission do not fall
under the value in a pre set time, the

message E759 "Unexpected

emission"

is displayed. This message can be also displayed if the signal

X-ray on is sensed during the idle state.
In this case, check the main CPU board (A5) and the local Generator CPU
board (A9) and the cable X20-X20. If all OK, replace the Generator board.

The emission is controlled also through a safety backup timer that
interrupts the power to the tubehead also in case of a fault (hardware or
software) to the Generator CPU board. The intervention of the backup
timer,

message E755

, is signalled by a lighting of the red LED H4.

This alarm can be reset only by powering off the unit, wait for at least 1
minute and power it on again. If the LED H4 continues to be ON, replace
the Generator board.
If the LED, after the power ON is not lighted, repeat an emission and, if
the message is appearing again, replace the Generator board.
