6.6.5.9 Inverter Alarms
The Supervisor can enable an inverter alarm for any of the following conditions:
Alarm Name Alarm Condition
Inverter Major Fail Count Number of failed Inverters equals or exceeds a user configured threshold
Inverter Minor Fail Count Number of failed Inverters equals or exceeds a user configurable threshold
Inverter Comms Lost Controller loses communications with any one inverter. The number of
inverters must be correctly identified in the Set Output menu.
Inverter AC Input Fail Main AC input of the inverter is lost
Inverter Alarm Any individual or system alarm is detected
6.6.6 ADIO Alarms Detail
6.6.6.1 View Details
This menu item enables the user to select an ADIO device (i.e., Cordex Smart Peripheral) that is con-
nected to the CXC and view the alarms with respect to: Cell Deviation, Current, Voltage, Temperature,
and Comms.
6.6.7 Alarm Hysteresis
6.6.7.1 Voltage
Voltage Hysteresis applies only to Voltage Alarms (6.6.5.2). This value is the voltage range where the
alarm can clear or activate. For example, if the low voltage alarm activates at 43.00 V, having a voltage
hysteresis of 0.50 V means it will clear when the voltage reaches 43.50 V.
6.6.7.2 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 be-
low 43.00 V for at least 5 seconds before the alarm is activated. Similarly, to clear the alarm, the voltage
must be above 43.50 V for 5 seconds.
This feature is used only for the following:
• Current, Voltage, Battery, and Temperature alarms
• HVSD and CEMF controls.
