The following sub-section describes the converter alarms menu headings and the associated items.

6.5.3.11Converter Alarms

Converter Fail

This menu item enables the Supervisor to set an alarm condition for a true or actual converter failure. The activation value is factory set.

Converter Minor

This menu item enables the Supervisor to set an alarm condition for a minor converter failure; i.e., an alarm condition detected in a converter, but one that is not considered an immediate threat to the operation of that converter. The activation value is factory set.

Conv. Major Fail Count

This menu item enables the Supervisor to set the total number of converter fail alarms that will trigger the CXC’s converter major alarm. The activation value must be greater than or equal to the total number entered for the minor converter fail count alarm.

Conv. Minor Fail Count

This menu item enables the Supervisor to set the total number of converter fail alarms that will trigger the CXC’s converter minor alarm. The activation value must be less than or equal to the number entered for the major converter fail count alarm.

Conv. Out of Tolerance

This menu item enables the Supervisor to set an alarm condition when a converter out of tolerance is detected. The activation value is factory set.

Conv. Comms Lost

This menu item enables the Supervisor to set an alarm condition when converter communications is lost. The activation value is factory set.

Conv. Input Voltage Fail

This menu item enables the Supervisor to set an alarm condition when a converter input voltage fail is detected. The activation value is factory set.

The activation value for Input Voltage Fail detection is determined to be when the number of converters in Input Voltage Fail divided by the number of converters acquired is greater than or equal to 90%.

Conv. Fan Fail

The purpose of this feature is to enable the CXC to trigger the alarm when a fan fail (speed error or failed fan) condition has occurred in any of the converters in the system.

The Fan Fail Alarm is true when the CXC receives a Fan Fail or Fan Speed Error alarm from any converter.

The Fan Fail Alarm is cleared when all Fan Fail and Fan Speed Error alarms are cleared from all the converters.

Each time that the Fan Fail Alarm goes on/off, the “event” is logged in the Event History. Since it is a converter alarm, up to nine converters (up to 27 fan fail alarms) that are in alarm will be logged. If more than nine converters are in alarm an additional entry will be made indicating the total number of converters in alarm.

The activation value is factory set.

Conv. Load Current High

This menu item enables the Supervisor to program the setting for the converter load amps alarm. When the current to the load has exceeded this setting, an alarm is activated and the message CONV. LOAD CURRENT HIGH is displayed on the GUI.

Conv. Low Output Voltage

When the converter’s output voltage falls below the Supervisor-specified value, the alarm is activated and the message CONV. LOW OUTPUT VOLTAGE is displayed on the GUI.

Conv. High Output Voltage

When the converter’s output voltage exceeds the Supervisor-specified value, the alarm is activated and the message CONV. HIGH OUTPUT VOLTAGE is displayed on the GUI.
