7.5. 7.5. Advanced Alarms Advanced Alarms
ATevo alarms can be divided into two groups: Legacy AT30 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.
7.5.1 High Voltage Shutdown Alarm 7.5.1 High Voltage Shutdown Alarm
This alarm is activated when ATevo initiates a High Voltage Shutdown, provided that feature
has been enabled. See

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
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.
