CHAPTER 7: Alarm Configuration

Subject: This parameter is used to define the text that will appear in the "Subject" field for all email notification messages generated by the alarm. (Defaults = "Alarm: Over Current (Initial)" or "Alarm: Over

Current (Critical)")

Load Shedding: Provides access to a submenu which is used to configure and enable the Load Shedding feature for the Over Current Alarm. When Load Shedding is enabled and properly configured, the Outlet Managed PDU will switch user-selected plugs On or Off whenever the current load exceeds the Alarm Set Threshold value. If the Auto Recovery feature is enabled, the Outlet Managed PDU can also return these user-selected plugs to their prior status when current load falls below the Alarm Clear Threshold value. For more information on the Load Shedding Feature and Auto Recovery, please refer to Section 7.1.1.

7.1.1.Over Current Alarms - Load Shedding and Auto Recovery

The Load Shedding feature is used to switch specific, user-defined, non-essential plugs On or Off whenever current load exceeds the Alarm Set Threshold value. This allows the Outlet Managed PDU to automatically shut Off plugs in order to reduce current load when the load approaches user-defined critical levels. When the Auto Recovery feature is enabled, the Outlet Managed PDU can also automatically "undo" the effects of the Load Shedding feature when current load again falls to a user- defined non-critical level.

The Outlet Managed PDU also allows you to define separate Load Shedding/ Recovery actions for an Over Current Branch Alarm and an Over Current Line Alarm. For example, if the Line Alarm is triggered, Load Shedding can switch Off Plugs A1 and B1, yet when the Branch "A" Alarm is triggered, the Outlet Managed PDU can switch Off Plugs A1 and A2.

Together, the Load Shedding and Auto Recovery features allow the Outlet Managed PDU to shut off power to non-essential devices when the current load is too high, and then switch those same non-essential devices back On again when the load falls to an acceptable level.

Note:

The Load Shedding Configuration Menus for all Over Current Alarms offer essentially the same set of parameters, but parameters defined for each alarm are separate and unique. For example, parameters defined for Over Current (Initial) Alarm Load Shedding will not be applied to Over Current (Critical) Alarm Load Shedding and vice versa.
