The component Variables of the HighVoltageUnitType have additional Attributes defined in Table 69.

Table 69 – HighVoltageUnitType Attribute values for child nodes

BrowsePath	Description Attribute
SupplyActive	Indicates that the high-voltage generator is emitting high voltage.
CurrentOutput	Current output of the high voltage unit.
Malfunction	Indicates that the high voltage generator is malfunctioning (e.g., excess/insufficient voltage, overheating, etc). True in case of error.
MaintenanceRequested	Indicates that maintenance is requested for the high voltage generator.
<Ionizer>	The ionizers of the high voltage unit.
<Collector>	The collectors of the high voltage unit.

The Ionizer and Collector placeholders contain a list of ionizers and collectors, each of which provides an output value.

The HighVoltageUnitSupplyActiveEventType is triggered when the SupplyActive property changes.

The server sends a MalfunctionAlarmType event when the Malfunction property changes.

The MaintenanceRequestedConditionType is sent when the MaintenanceRequested property changes.
