Scanner fault detected
[Fault]
An unspecified fault condition has occurred, and the scanner X-ray generation
stages are shut down as a precaution. Turn the key off and then on again to
attempt to reset the scanner. If the fault condition persists, turn the key off and
contact AS&E.
Scanner hot
[Warning]
There are two thermal thresholds for scanner operating temperature. When the
scanner reaches the first limit, a warning message is displayed. The user should
suspend scanning for a period of time until the system temperature decreases
and the warning message is removed. If the temperature continues to increase
and reaches the second limit, the system disables scanning until the system
temperature reduces.
Tablet battery low
[Warning]
The tablet power level is low, and the user should suspend operations and
recharge the tablet.
Tablet disk space low
[Warning]
The allocated space for data on the tablet solid state hard drive is nearly full (5%
free). The user should suspend operations and clear space for new images by
backing up images to an external storage device and deleting those same
images from the tablet hard drive.
Trigger stuck on
[Fault]
At power on, the initialization test found one or both of the trigger switches on
the scanner handle were closed for more than 3 seconds of time, and the
power-on sequence is incomplete. Remove any object that may be pressing on
either switch button, and press the switches a few times gently to move them.
Turn the key off and then on again to attempt to reset the scanner. If the fault
condition persists, turn the key off and contact AS&E.
X-Ray current error
[Fault]
There are two output current thresholds for the scanner X-ray tube. When the
scanner output current rises to more than 10% above its target value during
scanning, this fault message is displayed, and the scanner X-ray generation
stages are shut down as a precaution. Turn the key off and then on again to
attempt to reset the scanner. If the fault condition persists, turn the key off and
contact AS&E.
X-Ray current is low
[Warning]
There are two output current thresholds for the scanner X-ray tube. When the
scanner output current drops more than 10% below its target value during
scanning, this warning message is displayed. The user should suspend
operation until the output level increases and the warning message is removed.
X-Ray KV error
[Fault]
There are two output voltage thresholds for the scanner X-ray tube. When the
scanner output voltage rises to more than 10% above its target value during
scanning, this fault message is displayed, and the scanner X-ray generation
stages are shut down as a precaution. Turn the key off and then on again to
attempt to reset the scanner. If the fault condition persists, turn the key off and
contact AS&E.
X-Ray lamp 1 failure
[Warning]
One of the two independent “X-ray on” indicator LEDs circuits (referred to as
lamp circuit 1
) had current levels that were 10% too high or too low, and the
scanner X-ray generation stages are shut down as a precaution. Turn the key
off and then on again to attempt to reset the scanner. If the fault condition
persists, turn the key off and contact AS&E.
