Functional Description
This chapter describes how the BE2000E functions and explains its operating features. To ease
understanding, BE2000E functions are illustrated in the block diagram of Figure 3. A detailed description
of each function block is provided in the paragraphs under the heading of
BE2000E Function Blocks .
BE2000E operating features include four operating modes, four protective functions, startup provisions,
reactive droop compensation, underfrequency compensation, and an auxiliary analog input. A detailed
description of each operating feature is provided in the paragraphs under the heading of
BE2000E

BE2000E Function Blocks
The following paragraphs describe each of the function blocks illustrated in Figure 3. The function of each
block is explained along with the operation of all function block inputs and outputs.
Analog Inputs
Six analog voltage and current inputs may be sensed and brought to the BE2000E input.
Generator Voltage
Generator voltage is monitored at terminals E1 (A-phase), E2 (B-phase), and E3 (C-phase). Nominal
voltages of up to 600Vac may be sensed at these terminals. Voltage applied to these inputs is scaled and
conditioned before being applied to the input of the ADC. The voltage signal from phase C and A (V
C-A
) of
the generator is used by the ADC to calculate the rms value of generator voltage across phases C and A.
