Explanation
A rotation movement has stopped
at a firmware limit, but should
have stopped before.
An arm movement control button
on an arm keypad (behind the
image receptor, left or right) was
pressed during the boot sequence
while the Gantry checked its
devices.
The button that was pressed is
not functional until the next
reboot.
The compression device is not
correctly calibrated; no movement
will be available until the com-
pression device has been cor-
rectly calibrated.
An error occurred during com-
pression movement; it does not
affect the safety control, but only
the speed profile.
An arm movement control button
on a X-ray tube head keypad (left
or right) was pressed during the
boot sequence while the Gantry
checked its devices.
The button that was pressed is
not functional until the next
reboot.
The system is in degraded mode:
- The tube head fan has failed. As
a result, tube cooling is not effi-
cient and the tube thermal algo-
rithm could not prevent exposure
abort due to tube overheating.
An error is detected by the Gantry
power unit that does not affect the
safety control.
