Front Panel Indicators
Eight front-panel LED indicators light to indicate various protective functions and operating modes.
Section 2, Human-Machine Interface provides more information about the front panel indicators.
Relay Output
A common alarm output contact is provided through terminals AL1 and AL2. This normally open, form A
contact annunciates alarm or trip conditions. The relay output is non-latching.
DECS-100 OPERATING FEATURES
The following paragraphs describe the characteristics of each DECS-100 operating feature.
Operating Modes
The DECS-100 provides up to four modes of operation selectable through BESTCOMS software.
Automatic voltage regulation mode and Manual mode are standard features. Var and Power Factor
modes are an option.
Automatic Voltage Regulation Mode
In Automatic Voltage Regulation (AVR) mode, the DECS-100 regulates rms generator output voltage.
This is accomplished by sensing generator output voltage and adjusting dc output excitation current to
maintain voltage at the regulation setpoint. The regulation setpoint is adjusted by the Raise and Lower contact inputs, the Accessory input, or through BESTCOMS software. The regulation point may also be
modified by the Droop function or the Underfrequency function under certain conditions.
Manual Mode
In Manual mode, also known as Field Current Regulation (FCR) mode, the DECS-100 maintains dc
excitation current at a set level. The current-level setpoint is adjustable from 0 to 7 Adc in 0.1 Adc
increments by the Raise and Lower contact inputs, the optional Accessory input, or through BESTCOMS
software. In Var Control mode, the DECS-100 maintains generator vars (volt-amperes, reactive) at a set level when
paralleling with an infinite bus. The DECS-100 calculates generator vars by using the sensed generator
output voltage and current quantities. It then adjusts the dc excitation current to maintain vars at the
setpoint. Var control is enabled and disabled through BESTCOMS software. When the software is turned
on, var control is enabled or disabled through the Var/Power Factor Control (52J/K) contact input circuit.
The var setpoint is adjustable from 100 percent absorb to 100 percent generate through the Raise and
Lower contact inputs, the optional Accessory input, or through BESTCOMS software.
Power Factor Control Mode (Optional)
In Power Factor Control mode, the DECS-100 maintains generator power factor at a set level when
paralleling with an infinite bus. The DECS-100 calculates generator power factor using the sensed
generator output voltage and current quantities and then adjusts the dc excitation current to maintain
power factor at the setpoint. Power factor control is enabled or disabled through BESTCOMS software.
When the software is turned on, it is enabled or disabled through the Var/Power Factor Control (52J/K)
contact input circuit. The power factor setpoint is adjustable between 0.6 lag and 0.6 lead through the
Raise and Lower contact inputs, the optional Accessory input, or through BESTCOMS software.
