Alarm Configuration
7.2.1.1. Load Shedding & Auto Recovery Configuration - Text Interface
In the Text Interface, Load Shedding parameters for the Over Temperature Alarm 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, type 5 and press [Enter] to
access the Load Shedding Configuration Menu. The following parameters will be
available:
1. Unit to Configure: 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 Load Shedding parameters for.
(Default = Local.)
2. Configure Load Shedding for Unit: Provides access to a submenu that is
used to define Over Temperature Alarm Load Shedding parameters for the unit
selected at the "Unit to Configure" prompt as described in the next step.
3. After defining the "Unit to Configure" parameter, use type 2 and press [Enter] to
define Load Shedding parameters for the selected unit. The Over Temperature
Alarm Load Shedding Configuration Menu offers the following parameters:
1. Enable: Enables/Disables Load Shedding for the Over Temperature Alarm.
When enabled, the MPC will switch the user specified plugs whenever the
temperature 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 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.)
3. Auto Recovery: Enables/Disables the Auto Recovery feature for the selected
unit. 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 returned to an acceptable level.
(Default = Off.)
4. 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 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 7.2.1.3
for additional instructions regarding granting access to plugs on AUX units.
