SECTION 2 • HUMAN-MACHINE INTERFACE
GENERAL
The DECS-100 human-machine interface (HMI) consist of front panel indicators and a rear panel
communication port.
FRONT PANEL INDICATORS
DECS-100 front panel indicators consist of seven red LEDs. Figure 2-1 shows the front panel indicators for
the DECS-100. Table 2-1 describes the function of each front panel indicator.

Indicator
Description
Overexcitation Shutdown
This LED lights when the Overexcitation Protection feature is
enabled and the field voltage exceeds 100 Vdc for 10 seconds. The
DECS-100 will shutdown when an overexcitation condition is
detected. The Overexcitation Shutdown LED will light for 5 seconds
when the DECS-100 is powered up following an overexcitation
shutdown.
Generator Overvoltage
This LED lights when generator output voltage exceeds the
adjustable setpoint for 0.75 seconds. The DECS-100 will shutdown
when a generator overvoltage condition is detected. The Generator
Overvoltage LED will light for 5 seconds when the DECS-100 is
powered up following a generator overvoltage shutdown.
