Alarm Configuration
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
temperature 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.
7.1.1.2. Load Shedding & Auto Recovery Configuration - Web Browser Interface
In the Web Browser Interface, Load Shedding and Auto Recovery parameters for the
Over Temperature Alarms are defined as follows:
1. Access the Over Temperature Alarm Configuration Menu as described in
Section 7.2.
2. At the Over Temperature Alarm Configuration Menu, use the drop down menu next
to the Load Shedding button to determine the Local/AUX MPC unit. When optional,
remote MPC or BPM units have been connected to your local MPC's AUX ports,
this parameter is used to select the Local or AUX unit that you wish to define Over
Temperature Alarm Load Shedding parameters for. (Default = Local.)
3. After selecting the Local/AUX unit, click on the Load Shedding button to select
parameters for the selected unit. The resulting submenu will offer the following
options:
• Enable: Enables/Disables Load Shedding for the selected unit. When enabled,
the MPC will switch the user specified Plugs or Plug Groups whenever the
temperature exceeds the user-defined 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 at the selected unit. (Default = Off.)
• Auto Recovery: 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 at the selected unit. 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.)
