If one of the above tests (a., b. or c.) fails, replace the tubehead (see paragraph
11.3.9).
4.
If the error is still present, replace both the tubehead and Generator board.
Technical Service additional information required
: try to reproduce the error keeping
the following logs:
-
Software logs
-
MCU SD card log (see paragraph 11.2.1).
9.2.7.10
E759: Alarm “Unexpected emission”
An unexpected emission has been detected by the Generator board.
1.
With the unit switched OFF (at least for 4 minutes), verify the proper connection
of the pins X57-1 and X57-4; connect them and verify if the error is still present.
2.
With the unit switched OFF (at least for 4 minutes), verify the Ohmic resistance
between the TP10 (mA feedback) and GND (TP13), it should be between 326Ω
÷ 334Ω. If it is NOT OK, remove the connector X-57 and repeat the Ohmic test
on the connector (tubehead side).
IF the test is NOT OK, replace the tubehead (see paragraph 11.3.9).
IF the test is OK, replace the Generator Board.
3.
If the error is still present,
it is mandatory
NOT use or switch ON the system
anymore
and contact Technical Service.
9.2.7.11
E760: Alarm “NO RX button command”
This message is displayed when the Generator board (A2) is not detecting the X-ray
button during the emission.
If the X-ray button was NOT intentionally released, switch OFF and ON the unit. Wait
the keyboard blinks (DO NOT press the >0< button) and perform the following
checks:
1.
Press the X-ray button and verify that the LED H11 on MCU board (A1) light-up
according to the X-ray button activation.
IF the test is NOT OK, verify the connected X-ray buttons and their connections:
replace or fix them and verify if the error is still present. If still present, replace
the MCU board (see paragraph 11.3.2).
