6.5.3.11 Converter 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.

ADIO Alarms Detail

6.5.4.1

View Details

This menu item enables the user to select an ADIO device (i.e., Cordex Smart Peripheral) that

is connected to the CXC and view the alarms with respect to: Cell Deviation, Current, Voltage,

Temperature, and Comms.

6.5.5

Alarm Hysteresis

6.5.5.1

6.5.5.2

Voltage

Voltage Hysteresis applies only to Voltage Alarms (6.5.3.5). This value is the voltage range

where the alarm can clear or activate. For example, if the low voltage alarm activates at 43.00V,

having a voltage hysteresis of 0.50V means it will clear when the voltage reaches 43.50V.

Time

Time Hysteresis is the amount of time in seconds that the condition has to be true before the

alarm is enunciated. In the example above, if the value of time hysteresis is 5 seconds, the

voltage must be below 43.00V for at least 5 seconds before the alarm is activated. Similarly, to

clear the alarm, the voltage must be above 43.50V for 5 seconds.

This feature is used only for the following:





Current, Voltage, Battery, and Temperature alarms

HVSD and CEMF controls.

6.5.6

Alarm Tone

This feature is found under the Global Alarm Configuration menu (submenu of Alarms) and the tone is enabled

by default. The Supervisor may enable/disable the Audible Alarm Buzzer (tone). Enabling the Loud Buzzer

option increases the pitch and volume of the buzzer.
