Logic Schemes
A logic scheme is a group of logic variables that defines the operation of a BE1-11 m . Each logic scheme
is given a unique name. This gives you the ability to select a specific scheme and be confident that the
selected scheme is in operation. One logic scheme is configured for typical control applications and is the
default active logic scheme. Only one logic scheme can be active at a given time. In most applications,
preprogrammed logic schemes eliminate the need for custom programming. Preprogrammed logic
schemes can provide more inputs, outputs, or features than are needed for a particular application. This
is because a preprogrammed scheme is designed for a large number of applications with no special
programming required. Unneeded logic block outputs can be left open to disable a function or a function
block can be disabled through operating settings.
When a custom logic scheme is required, programming time is reduced by modifying the default logic
scheme.
Default Logic Scheme
All BE1-11 m protection systems are delivered with the default logic scheme pre-loaded in memory . If the
function block configuration and output logic of the default logic scheme meets the requirements of your
application, then only the operating settings (power system parameters and threshold settings) need to be
adjusted before placing the BE1-11
m
in service.
Details of Default Logic Scheme describes the characteristics of the logic scheme and how it combines to
create a Motor Protection System. A detailed description of the default scheme is also provided.
The default logic scheme is designed to accommodate most common motor protection schemes. The
protection engineer can adapt it by changing the function block operation and settings. This eliminates the
need to create a custom logic scheme.
It should be noted that the default logic scheme also illustrates typical ways of using or controlling various
functions. The user can choose to create a custom logic scheme by mixing the logic from the default
scheme. The flexibility of BESTlogic Plus allows the protection engineer to create a custom scheme that
exactly meets the requirements of the application.
