for remote system management. The controller supports software upgrade via its USB port.
Refer to the NCU controller instructions (UM1M830BNA) for more information.
Note:
In this system, the NCU Ethernet port is connected to a front panel touch screen PC for
local access to the NCU webpages. An IB4 (second Ethernet port board) is also
furnished which provides a connection point for a remote monitoring Ethernet
connection.
•
SM-DUE (if furnished)
The SM-DUE is used to input external monitoring information to the NCU controller. The SM-DUE
provides the following monitoring inputs:
Ten (10) input blocks with each providing the following monitoring inputs:
One (1) Load Bus Voltage (0 VDC to 60 VDC) per input block
One (1) Load Fuse Alarm (Bus- base of 0 VDC, >10 VDC alarm, <10 VDC normal) per
input block
One (1) Programmable Analog Input, can be set to accept one (1) of the following inputs
per input block:
10 mV DC to 50 mV DC Load Shunt (only load shunts are supported at this time)
General-Purpose Current Transducer
General-Purpose Voltage Transducer
1 uA/K Temperature Sensor
The SM-DUE also contains a +5 VDC power supply output for connection to external Hall devices.
The SM-DUE connects into the NCU CAN bus. Up to eight (8) SM-DUE units can be connected to
an NCU.
•
MCA (Meter-Control-Alarm) (if furnished)
The MCA controls the operation of the rectifiers and provides power system control, metering,
monitoring, and alarm functions.
MCA Local Control Panel:
This panel is located on the front of the primary power/distribution or
power only bay and contains a keypad, display, and indicators for local MCA User interface.
MCA Relay Circuit Card:
Each MCA relay circuit card provides six (6) sets of Form-C relay
contacts for customer external alarms. These relays are User programmable for various power
system alarms. Up to sixteen (16) MCA relay circuit cards can be installed in the primary and
secondary power/distribution and power only bays. The primary power/distribution and power
only bays are factory equipped with two (2) MCA relay circuit cards.
MCA I/O Circuit Cards:
The MCA I/O circuit cards provide analog inputs/outputs and binary
inputs. Up to sixteen (16) MCA I/O circuit cards can be installed in the primary and secondary
power/distribution and power only bays.
•
Optional Integrated LMS Monitoring System (if furnished)
The LMS monitoring system consists of an LMS main CPU circuit card, optional LMS expansion
CPU circuit cards, optional LMS I/O circuit cards, optional LMS expansion cabinet, and optional
LMS expansion assemblies.
The LMS main CPU circuit card is mounted in the primary power/distribution and power only
bays. Each secondary power/distribution and power only bay that is to be equipped with optional
LMS I/O circuit cards must contain an LMS expansion CPU circuit card. LMS expansion cabinets
and LMS expansion assemblies are available that mount into customer equipment.
The LMS monitoring system is factory integrated within each power/distribution, power only, and
distribution only bay and requires no additional customer interconnections within the bays.
Simple cable connections between the power/distribution, power only, and distribution only bays
complete the interbay connections required. Separate analog, binary, and relay circuit cards do
not have to be supplied for power system monitoring. Analog, binary, relay, and temperature
circuit cards can be provided to monitor equipment external to the power system.
The LMS input circuit cards monitor a variety of analog, binary, and temperature points external
to the system. An LMS relay output circuit card is also available which provides programmable
relays. These relays may be used for external alarms, or to control other equipment.
