Introduction

The BE1-11d DC Power Protection System provides flexible, reliable, and

economical dc power protection, control, monitoring, and measurement

functions. The capabilities of the BE1-11d make it well suited to provide

comprehensive dc power protection. The BE1-11d offers dc overcurrent,

over/undervoltage, rate of rise, power, and thermal overload protection

functions as well as breaker reclosing and RTD (Resistance Temperature

Detector) inputs with remote module. It offers breaker and trip-circuit

monitoring, and oscillography and sequential events recording.

Control features include virtual selector switches, circuit breaker control,

virtual lockout, and variable-mode timers. System metering and status

information are available at the BE1-11d front panel and through the

BE1-11d communication ports. The system is suitable for mounting in

OEM cubicle or retrofit switchgear applications.

A front-panel USB port or optional rear Ethernet port enables local

communication between the BE1-11d and a PC operating with

BESTCOMSPlus® software. BESTCOMSPlus software simplifies the

commissioning process by providing a graphical interface for setting

the BE1-11d and configuring a protection and control scheme for your

application. Through BESTCOMSPlus, all BE1-11d settings and logic can

be retained in a file for printing or uploading to other BE1-11d protection

systems. Oscillography and sequential events records can be retrieved

from a BE1-11d, viewed, and printed.

Front-panel features include a large, backlit alphanumeric display and LED

indicators that display system parameters, BE1-11d settings, and BE1-11d

status. Pushbuttons enable navigation through the display menu, changes

to settings, resetting of targets (with password access), and direct access

to virtual switches.
