5.12 LOAD SHED COMMAND (EMCP 4.3 AND 4.4)
The active status determines whether load shed command is active, and the reset allows the command to
be inactivated, but only if all of the forcing conditions are no longer present. For more information on Load
Shed Command, see the EMCP 4 Application and Installation Guide.
 Load Shed Command Active Status (1129)
 Load Shed Command Reset (1130)
