System OperationCopyright © 2007-2011 Eaton Corporation. All Rights Reserved.IPN 997-00012-50H November 2011 47The following system alarms have particular configuration settings:System Overload alarm. See details on page 47.Battery Mid-point monitoring. See details on page 57.Alarm InhibitingTo prevent a single series of faults triggering multiple alarms, an alarm is inhibited by anotheractive alarm if the conditions that trigger the inhibiting alarm include the conditions that triggerthe inhibited alarm. However, the inhibiting alarm only inhibits if it is set to a level of severitythat is equal to or higher than the alarm being inhibited.For example, Partial AC Fail is inhibited if AC Fail is active and AC Fail is set to a level of severitythat is equal to or higher than Partial AC Fail.Alarm Descriptions on page 109 lists the inhibiting alarms that can inhibit each alarm.System Overload AlarmThe System Overload alarm activates if the total system load exceeds a percentage of theinstalled rectifier capacity for a specified period (or if the total system load exceeds a percentageof the installed rectifier capacity minus the capacity of the largest rectifier if System OverloadType is set to Redundancy). This indicates that additional rectifiers need to be installed. This isuseful at sites where there is ongoing installation of additional load equipment.► To enable System OverloadIn DCTools/Web go to: Alarms > Alarm States.
