Alarm Configuration
The Load Shedding configuration menus for both the Over Temperature (Initial
Threshold) alarm and the Over Temperature (Critical Threshold) alarm offer the following
parameters:
• Enable: Enables/Disables Load Shedding for the corresponding alarm. When
enabled, the MPC will switch the user specified plugs whenever the temperature
exceeds the Alarm Set Threshold value. (Default = Disable.)
• Plug State: Determines whether the selected plugs/plug groups will be switched
On or Off when Load Shedding is enabled and the temperature exceeds the user-
defined Alarm Set Threshold. For example, if the Plug State is set to "Off", then the
selected plugs/plug groups will be switched Off when the Alarm Set Threshold is
exceeded. (Default = Off.)
• Auto Recovery: Enables/Disables the Auto Recovery feature. When both Load
Shedding and Auto Recovery are enabled, the MPC will return plugs to their former
On/Off state after the temperature falls below the Alarm Clear Threshold value.
This allows the MPC to "undo" the effects of the Load Shedding feature after the
temperature has returned to an acceptable level. (Default = Off.)
• Plug Access: Determines which Plug(s) will be switched when the temperature
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 temperature exceeds the Alarm Set Threshold.
(Default = undefined.)
Notes:

• In the Web Browser Interface, Plug Access is configured by clicking on the
