When a custom logic scheme is required, programming time can be reduced by copying a
preprogrammed scheme into the active logic. The logic scheme can then be modified to meet the specific
application.
The Active Logic Scheme
Digital, multifunction relays must have an active logic scheme in order to function. All Basler Electric
multifunction relays are delivered with a default, active logic loaded into memory. The default, active logic
scheme for the BE1-CDS240 is named CDS240-BATX-A-BE. If the function element configuration and
output logic of Basic Transformer 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 relay in service.
If you wish to modify the scheme, it must be saved under a different name than that found in the logic
library (read only files). Any of the preprogrammed logic schemes discussed in Section 8,
Application,
can
be copied to the active logic and customized, or used as is. To copy a logic scheme into active logic,
select the scheme from the BESTCOMS logic library and upload it to the relay. To modify the
preprogrammed scheme, it is necessary to enter a unique name for the new logic before modifying the
settings. Naming the new logic distinguishes it from the preprogrammed logic scheme. In the 16 character
preprogrammed logic name, the last 4 characters refer to revision A, dash (-), and BE (Basler Electric).
When customizing a programmed logic scheme, it is recommended that the user include the revision level
of their scheme and change the BE to a 2-digit code representative of the user's company name. For
example, if VA Power were modifying the CDS240-BATX-A-BE logic scheme, the preprogrammed logic
scheme might be CDS240-BATX-B-VP. The B stands for revision level B and VP stands for VA Power.
After a preprogrammed logic scheme is uploaded to the relay from BESTCOMS, it can also be renamed
with the SL-N<name> and customized using ASCII commands.
Logic schemes can be selected from the logic select tab on the
BESTlogic
screen. To access this screen,
select
BESTlogic
from the
Screens
pull-down menu. Then select the
Logic Select
tab. Select the desired
logic scheme to
Copy to Active Logic
(Internal Logic). The active logic scheme is shown in the
Logic
Name
box. In Figure 7-8, CDS240-BATX-A-BE has been selected as the user logic.

CAUTION
Selecting a logic scheme to be active in BESTCOMS does not automatically
make that scheme active in the relay. See the paragraphs later in this section
titled,
Sending and Retrieving Relay Settings.
