Manual Mode Active
This LED lights when the DECS-100 is operating in Manual mode. Manual mode is enabled through
BESTCOMS software.
Underfrequency Active
This LED lights when the generator frequency decreases below the underfrequency setpoint and the
DECS-100 is regulating on the selected volts per hertz curve.
COMMUNICATION PORT
The communication port is located on the rear panel and
consists of a female, RS-232 (DECS-B-9) connector. The
communication port serves as an interface for programming
(setup) of the DECS-100. Figure 2-2 illustrates the location of
the communication port.
Programming requires a standard, nine-pin, serial
communication cable connected between the DECS-100 and
an IBM-compatible PC operating with BESTCOMS software.
BESTCOMS software is a Microsoft Windows?-based
communication software package that is supplied with the
DECS-100. A detailed description of BESTCOMS is provided
in Section 5, BESTCOMS Software. This section describes how the DECS-100 functions and explains its operating features. To ease
understanding, DECS-100 functions are illustrated in the block diagram of Figure 3-1. A detailed
description of each function block is provided in the paragraphs under the heading of DECS-100 Function
Blocks.
DECS-100 operating features include four operating modes, four protective functions, startup provisions,
reactive droop compensation, underfrequency compensation, and optional voltage matching. A detailed
description of each operating feature is provided in the paragraphs under the heading of DECS-100
Operating Features. The following paragraphs describe each of the function blocks illustrated in Figure 3-1. The function of
each block is explained along with the operation of all function block inputs and outputs.
Analog Input Circuits
Seven analog voltages and current may be sensed and applied to the DECS-100.
Bus Voltage
C-phase and A-phase bus voltages are monitored at terminals B3 and B1 on units that include voltage
matching. Nominal voltages of up to 600 Vac may be sensed at these terminals. Voltage monitored at this
input is scaled and conditioned before being applied to the input of the analog-to-digital converter (ADC).
This bus voltage signal applied to the ADC is used to calculate the rms value of the bus voltage across
phases C and A (Bus VC-A).
Generator Voltage
Generator voltage is monitored at terminals E1 (A-phase), E2 (B-phase), and E3 (C-phase). Nominal
voltages of up to 600 Vac may be sensed at these terminals. Voltage applied to these inputs is scaled and conditioned before being applied to the input of the ADC.
