3.After defining the "Unit to Configure" parameter, use items 2, 3, and 4 to select Load Shedding parameters for the selected branch or line. The Branch/Line Load Shedding Configuration Menus offer the following parameters:
1.Enable: Enables/Disables Load Shedding for the corresponding alarm. When enabled, the MPC will switch the user specified plugs whenever current load exceeds the Alarm Set Threshold value. (Default = Disable.)
2.Plug State: Determines whether the selected plugs/plug groups will be switched On or Off when Load Shedding is enabled and current load exceeds the
3.Auto Recovery: Enables/Disables the Auto Recovery feature for the selected unit/branch/line. When both Load Shedding and Auto Recovery are enabled, the MPC will return plugs to their former On/Off state after the current load falls below the Alarm Clear Threshold value. This allows the MPC to "undo" the effects of the Load Shedding feature after the current load has returned to an acceptable level. (Default = Off.)
4.Plug Access: Determines which Plug(s) will be switched when the current load exceeds the Alarm Set Threshold and the Load Shedding feature is triggered. For example, if plugs A1, A2 and A3 are selected, then these plugs will be switched On or Off whenever the current load exceeds the Alarm Set Threshold. (Default = undefined.)
Notes:
•In the Text Interface, Plug Access is configured by typing 4, pressing [Enter] and then selecting the desired Plug(s) from the resulting submenu.
•If your installation includes optional AUX units, please refer to Section 7.1.1.3 for additional instructions regarding granting access to plugs on AUX units.
5.Plug Group Access: Determines which Plug Group(s) will be switched when the Load Shedding feature is triggered. For example, if you have defined
a Plug Group named "test", which includes Plugs B3, B4 and B5, and then selected the "test" Plug Group via the Plug Group Access parameter, then all of the plugs in the "test" Plug Group will be switched On or Off whenever the current load exceeds the Alarm Set Threshold. (Default = undefined.)
Notes:
•In the Text Interface, Plug Group Access is configured by typing 5, pressing [Enter] and then selecting the desired Plug Group(s) from the resulting submenu.
•Plug Groups must first be defined (as described in Section 5.6) before they will be displayed in the Load Shedding menu's Plug Group Access submenu.
