The Active Alarm List can display up to four active alarms at once but it is scrollable to view
any additional alarms present.
Alarm Logs
Alarm Logs
Alarms are system events that are stored in ATevo’s event log with a time and date stamp. The
same is true for alarm clearing (return to non-alarm state).

Advanced Alarms
ATevo alarms can be divided into two groups: Legacy ATevo Alarms (described in
)
and Advanced Alarms (described below):
Advanced Alarms:
• Do not have dedicated LEDs to indicate when they are active.
• Illuminate the COMMON ALARM LED and activate the common alarm relay
• Appear on the Active Alarm Bar and Active Alarm List.
• Get stored in the event log along with the time and date they occur and clear.
• Will be reported by any installed optional protocol communications board.
• May be configured to activate a discrete relay on optional Auxiliary I/O Boards.
High V
High Voltage Shutdown Alar
oltage Shutdown Alarm
m
This alarm is activated when ATevo initiates a High Voltage Shutdown, provided that feature
has been enabled. See
for details. High Voltage Shutdown is initiated by the micro-
controller when the dc bus voltage sensed by the Main Control Board (A1) is higher than the
High DC Voltage set point for a minimum of thirty (30) seconds.

evel Detect Alarm
m
This alarm is activated when the dc bus voltage sensed by the Main Control Board (A1) is lower
than the Low Level Detect set point. See
for details. The Low Level Detect feature
contains dedicated hardware, and operates independent of microprocessor control. The Low
Level Detect is a true
failsafe
feature that activates the common alarm relay in response to a
catastrophic failure, such as microprocessor failure. The Low Level Detect hardware will
illuminate a dedicated LED located on the Main Control Board (A1) when alarm is active.
