Each distribution bus accepts a choice of 218-type circuit breakers and TPL-type
fuses.
A Distribution Only Bay may also be equipped with an optional distribution panel
which accepts a choice of TPS/TLS-type fuseholders or Bullet Nose-type circuit
breakers.
Rectifiers
The rectifiers provide load power, battery float current, and battery recharge current
during normal operating conditions.
MCA (Meter-Control-Alarm)
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 Bay 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
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.
The LMS Monitoring System can be accessed via a local port, a modem port (when
optional modem is ordered), an optional TL1 port, and an Ethernet port (for Telnet
access, optional Web access, optional SNMP access, optional TL1 access, and
Email alarm reporting).
The LMS Monitoring System collects data from the power system and the input circuit
cards monitoring external points. The data collected is used for alarm processing
and reporting, and to provide statistics.
