Battery End of Discharge
Indicates DC output voltage is below Battery End Discharge factory alarm setpoint (see Table 15)
or the configured level if setpoint is adjusted using keypad or SENS Setup Utility. This alarm is
intended only for longer discharge rates (i.e. not engine starting applications) and indicates the
normal end-of-discharge voltage for a lead-acid battery. Alarm setpoint must be set lower than
LOW DC and BATTERY DISCHARGING alarms. Activates solid yellow DC LED. When this alarm is
assigned to a relay contact BATTERY END OF DISCHARGE will cause the assigned relay to change
to the Failed state after the time delay.

Module Failure
Indicates a power module within the charger has failed. One or more power modules is not able
to provide the current demanded by the battery and/or load or is providing more current than the
charger’s control system is commanding. This
alarm is typically caused by a module internal
component failure. This alarm does not occur during AC power failures. Activates solid red DC
LED. When this alarm is assigned to a relay contact MODULE FAIL will cause the assigned relay to
change to the Failed state after the time delay.
8.4.7.
Over Voltage Shutdown
Indicates that the charger has executed a high voltage shutdown and DC output voltage is above
Over Voltage Shutdown factory alarm setpoint (see Table 16) or the configured level if setpoint is
adjusted using keypad or SENS Setup Utility. The charger disables itself whenever excessive
output voltage occurs while the charger is delivering current. The overvoltage shutdown system is
protected against nuisance trips and will not execute if the high voltage condition is caused by an
external source including a parallel connected charger of any type. Activates solid red DC LED.
When this alarm is assigned to a relay contact OVERVOLTAGE SHUTDOWN will cause the assigned
relay to change to the Failed state after the time delay.
