BASLER DIGITAL GENSET CONTROLLER (OPTION)
The definitions below describe the controls and functions
of the digital genset controller (Figure 10).
1. LCD Display — Display consists of an LCD color touch
screen. The backlit, 272 × 480 pixel, color LCD serves
as the local information source for metering, alarms,
pre-alarms and protective functions. Touch-screen
capability provides convenient navigation through
metering and settings. Display operation is maintained
down to –4°F (−20°C).
2. Not In Auto Indicator — This red LED lights whenever
the DGC-2020HD is not operating in Auto mode.
3. Alarm Indicator — This red LED lights continuously
during alarm conditions and flashes during pre-alarm
conditions.
4. Supplying Load Indicator — This green LED lights
whenever the generator current is greater than the
emergency power supply (EPS) threshold current.
5. Voltage Selection Indicators — These three LEDs
light to indicate the selected voltage. The upper lamp
indicates 3-phase, 480-volt operation. The middle
lamp indicates 3-phase, 240-volt operation. The lower
lamp indicates idle running operation.
6. Alarm Silence Pushbutton — Press this button to
open the relay output programmed as the horn output.
7. Lamp Test Pushbutton — Press this button to test the
DGC-2020HD indicators by exercising all LCD pixels
and lighting all LEDs.
8. Auto Pushbutton and Mode Indicator — Press the
Auto button to place the DGC-2020HD in Auto mode.
The green Auto Mode LED lights when Auto mode
is active.
While in Auto mode, if the unit's auto-start contacts
are connected to a transfer switch and the contacts
between the terminals are closed, the unit will start
and automatically close the circuit breaker.
If running in parallel, the Basler controller will command
the unit to start and close the breaker based on load
demand. If a failure occurs with another generator
in the paralleled system, the controller will start and
synchronize, then close the motorized breaker to
electrically lock the unit in parallel.
If the bus is dead it will immediately close the circuit
breaker to provide power to the load(s). If the bus
is already hot from another generator it will first
synchronize, then close its breaker, then slowly ramp
up to share load if load is present.
