Description
2
Division by Zero
Displayed if an internal computation results in
a division by zero. Requires the power to be
recycled.
3
Divide Overflow
Displayed if an internal computation results in
a division of zero. Requires power to be
recycled.
4
kV too High
Generator error. Displayed when the
generator kV exceeds the desired value.
Latching error.
5
mA too High
Generator error. Displayed when the
generator mA exceeds the desired value.
Latching error.
9
Focal Spot Error
Generator error. Displayed after power up if
the sense of a dual focal spot filament setting
changes.
10
Bipolar Status Error
Generator error. Displayed after power up if
the sense of an anode tank changes.
11
Generator Over kV
Generator error. Displayed when the
generator kV exceeds a value set in the
combination of X-Ray tube and generator
data. Latching error.
12
Generator Over mA
Generator error. Displayed when the
generator mA exceeds a value set in the
combination of X-Ray tube and generator
data. Latching error.
13
Converter Current
Generator error. Displayed when an internal
current limit is exceeded in the generator drive
electronics. Latching error.
14
Converter Voltage
Generator error. Displayed when an internal
voltage limit is exceeded in the generator drive
electronics. Latching error.
15
No Cooler Flow
Displayed when the coolant flow rate is less
than the internal setting. Non-latching error;
will reset automatically. This error will
disconnect the safety contactor.
16
Check Cooling System
Displayed when the coolant temperature
exceeds the internal cooler limit. Non-latching
error; will reset automatically. This error will
disconnect the safety contactor.
18
kV too Low
Generator error. Displayed when the
generator kV fails to reach the desired value
within a defined period of time. Latching error.
19
mA too Low
Generator error. Displayed when the
generator mA fails to reach the desired value
within a defined period of time. Latching error.
22
X-Ray Decay too Slow
Generator error. Displayed if the decay of the
kV at the end of the exposure takes too long.
The system status will remain as X-Ray ON
until the kV threshold is reached.
