BE1-CDS220 General Information 1-5
is equivalent to choosing the devices required by your protection and control scheme and drawing
schematic diagrams to connect the inputs and outputs to obtain the desired operational logic.
•
Several preprogrammed logic schemes are provided and thoroughly documented in this manual
in Section 8, Applications. To use the relay in one of these applications, it is only necessary to
make that scheme active.
•
A set of custom logic settings is also available for you to optimize the functionality to the specific
needs of your operations practices and power system requirements.
Security
•
Security can be defined for three distinct functional access areas: Settings, Reports, and Control.
Each functional access area can be assigned a password. A global password can provide access
to all three functional areas. Each of these four passwords can be unique or multiple functional
access areas can have the same password.
•
A second dimension of security is provided by allowing the user to restrict access to any of the
three functional access areas from only specific communication ports. For example, you could set
security to deny access to control commands from the rear RS-232 port that is connected through
a modem to a telephone line.
•
Security settings only affect write access. You have read access from any port to any area.
Human-Machine Interface
•
Each BE1-CDS220 comes with a front panel display with LED indicators for power, relay trouble
alarm, minor alarm, major alarm, and trip. Each BE1-CDS also comes with the software
application program BESTCOMS-CDS220-16. This program is a user friendly, Windows® based
program that makes relay setup and support very easy.
•
The optional programmable graphical LCD allows the relay to replace local indication and control
functions such as panel metering, alarm annunciation, and control switches.
•
The HMI is set up in a menu tree with four scrolling buttons for navigation. Edit and Reset
pushbuttons provide access to change parameters and reset targets, alarms, and other registers.
The scrolling buttons are used for data entry when in edit mode. Edit mode is indicated by an Edit
LED on the Edit button.
•
The LCD has automatic priority logic to govern what is being displayed on the screen so that
when an operator approaches, the information of most interest is automatically displayed without
having to navigate the menu structure. The priorities are targets, then alarms, then the
programmable automatic scrolling list.
•
Up to 16 screens can be defined in the programmable automatic scroll list.
ASCII Command Interface
•
Three independent, isolated communications ports provide access to all functions in the relay.
Com 0 is a 9 pin RS-232 port located on the front of the case. Com 1 is a nine pin RS-232 port
located on the back of the case. Com 2 is a 3-wire, RS-485 port located on the back of the case.
•
Standard communications is an ASCII command interface to allow easy interaction with the relay
using standard, off the shelf, communications software.
•
The ASCII command interface is optimized to allow automating the procedure for setting the relay
by allowing settings files to be captured from the relay and edited using any software that
supports *.txt file format. These ASCII *.txt files can then be used to set the relay using the send
text file function of the communications software.
•
Modbus

and other common protocols are optionally available for the RS-485 communications
port. A separate instruction manual appropriate for the protocol comes with each unit. Consult the
product bulletin or the factory for availability of these options and instruction manuals.
