Description
Where to find:
DC High Voltage Set
Threshold
Whenever Bus voltage is higher than this set
threshold, system generates a DC high Voltage
alarm. This alarm can be latched.

DC High Voltage
Restore Offset
Restore point for clearing DC High Voltage alarm.
DC Over Voltage
Latch
If Enabled DC High Voltage alarm will be latched,
requiring a manual clearing of alarm.
DC Low Voltage Set
Threshold
Whenever Bus voltage is lower than this set
threshold, system generates a DC Low Voltage
alarm.
DC Low Voltage
Restore Offset
Restore point for clearing DC low voltage alarm.
DC Overload Set
Threshold
If system current (sum of load and all battery
currents) exceeds this DC Overload Alarm Threshold
(Normally 105% of System Capacity) system
generates DC Overload alarm. This alarm can be
latched.
DC Overload Offset
Threshold
Restore point for clearing DC Overload alarm.
DC Over Current
Latch
If Enabled DC Over Current alarm will be latched,
requiring a manual clearing of alarm.
When the DC High Voltage alarm condition becomes true, the system generates the DC High Voltage alarm.
The rectifier stops providing current for battery charging , but Loads are connected to system and remain
powered.
BATTERY LVD
The user can define Disconnect & Reconnect thresholds. These apply to all battery LVDs.
