Request Expanded Fault Status
Description:
The host requests that the firmware report the expanded Fault
Status. The expanded fault status provides additional information
about faults that are reported in the Request Fault Status
command. Specifically it separates out kV and mA regulation faults.
If a regulation fault is reported by the Request Fault Status
command, this command can be used to determine if the fault was
due to bad kV or mA regulation. It also indicates if an over-duty
fault occurred because an exposure was started when the inverter
temperature sensor read > 60c.

<CSUM><ETX>
Where: (ARG# is 0 or 1 in ASCII format)
<ARG1> kV Regulation Fault, (1 = Fault, 0 = No Fault). The
regulation fault reported in the request faults command was
due to kV regulation error.
<ARG2> mA Regulation Fault, (1 = Fault, 0 = No Fault). The
regulation fault reported in the request faults command was
due to mA regulation error.
<ARG3> Inverter Temperature Fault (1 = Fault, 0 = No Fault). The
Over-Duty fault reported in the request faults command was
due to an attempt to start an exposure when the Inverter
Temperature sensor reads over 60c.
<ARG4> Spare – For future expansion, will read as 0
Notes:
The expanded faults are also cleared by the “Reset Faults”
command.
There is normally no need to use this command
operationally, as the “Request Faults” command will indicate if
