M-6280A Digital Capacitor Bank Control
Front Panel Controls
Menu-driven access to all functions by way of six pushbuttons and a two-line alphanumeric display. There are
up to 30 programmable User Access Codes (Level 1 or Level 2) available to provide various levels of access
to the control functions.
The Capacitor Bank control offers a 2-line by 20 character LCD display (LED backlit) for enhanced viewing in
direct sunlight.
CLOSE/OPEN switch allows local manual Close and Open commands to be initiated.
REMOTE/AUTO - LOCAL MANUAL switch allows Automatic operation of the control or Manual operation from
the front panel by using the CLOSE/OPEN toggle switch.
VOLTAGE SOURCE switch disconnects all power from the unit when selected to the OFF position. The EXT
position allows the control to be powered from the front panel test jacks.
EXTERNAL POWER binding posts allow application of a 120 V RMS nominal voltage to the unit for testing.
METER OUT binding posts allow reading of the input voltage.
Smart Flash SD Card Slot
Allows the user to perform the following functions:
• Load Setpoints
• Save Setpoints • Save Data Log • Save Sequence of Events
• Save Oscillograph Records • Clone Save • Clone Load • Load DNP Config
• Save DNP Config • Firmware Update • Save Metering Data • Save Wake Screen Data
• SD Card User Access (Physical Security Key) • Quick Capture • Multiuser Access Code

LED Indicators
Front panel LED indicators show the following control conditions: REMOTE/AUTO, LOCAL/MANUAL ,
ALARM, NEUTRAL UNBALANCE, CLOSE, OPEN, CPU OK , RSSI and TX (Transmit) and RX (Receive).
Communications
The communication ports provide access to all features, including metering, software updates, and programming
of all functions. This is accomplished using a connection from any Windows
TM
-compatible computer running the
CapTalk
®
S-6280 Communications Software or SCADA communications software.
Protocols : The standard protocols included in the M-6280A are DNP3.0 and MODBUS
®
. The USB port uses
MODBUS for local communications. The optional Ethernet Port supports DNP3.0 and MODBUS protocols
simultaneously. DNP Master Source Address Authentication is supported allowing multiple SCADA Masters to
coexist on the same communications network.
Communications Via Direct Connection : CapTalk supports direct communication (MODBUS protocol) with
the M-6280A using the applicable connector (USB cable) for the computer. Additionally, the standard RS-232
communications port as well as the 2-wire RS-485 and Serial Fiber (ST or Vpin) optional communications ports
can be used to communicate via CapTalk.
Optional Ethernet Port : The optional Ethernet Port provides an RJ-45 (10/100 Base-T) or a (100 Base-Fx)
Fiber Optic interface for ethernet communication to the M-6280A. The protocols supported are: MODBUS over
TCP, DNP3.0 over TCP and DNP3.0 over UDP. The port supports up to eight concurrent connections. The
maximum number of allowed DNP connections is five for each protocol (5 for UDP, 5 for TCP). The maximum
number of MODBUS connections is eight. Ethernet Port settings can be configured manually or via DHCP
protocol. MODBUS protocol "Port Number" and DNP Protocol "Port Number" can be changed manually from
default values. DNP Master Source Address Authentication is supported allowing multiple SCADA Masters to
coexist on the same communications network. This option can be field installed.
