Typical Battery
Plant Description A basic block diagram of a typical dc battery plant is shown in Figure2-1.Thebatteryplant acceptsalternating current fromthe
commercial utility or a standby ac power source and rectifies it
to produce dc power for the using equipment. Control and alarm
functions are provided by the plant to interact with the rectifiers
and the office. In addition, the plant provides overcurrent
protection, charge, discharge, and distribution facilities. Battery
reserve automatically provides a source of dc power if the
commercial or standby ac fails. This battery reserve is
engineered to supply dc power for a specified period of time. In
normal practice, battery capacity is sized to provide 3to 8 hours
of reserve time.
Battery Plant
Subsystems Figure 2-2 illustrates the arrangement and interconnections of the typical dc battery plant subsystems from the ac input to the
dc output. These subsystems are defined as follows:
AC Distribution: connects the commercial and/or standby ac
power sources to the rectifiers within the plant and provides
overcurrent protection. This subsystem is usually supplied by
the customer.
Rectifiers: convertan ac source voltage intothe dcvoltage level
required to charge and float the batteries and to power the using
equipment.
Controller: provides the local and remote control, monitor and
diagnostic functions required to administer the battery plant.
Batteries: provide energy storage for an uninterrupted power
feed to the using equipment during loss of ac input or rectifier
failure.

design of the rectifiers reduces installation time to minutes,
permitting easy growth and maintenance without service
interruption.
The Lineage®2000 SR Series 50 ampere rectifiers operate over
208/240 Vac 50/60 Hz nominal single phase inputrange without
any necessary tap changes. A power factor correction circuit
incorporated in the design insures a power factor of 90 percent
or greater for loads above 50 percent of the full load rating. The
rectifiers provide the ECS controller with a full complement of
status and alarm signals. The SR Series 50 ampere rectifier is
both UL recognized and CSA certified.
The rectifier status and alarm signals, ac input, and dc output are
all connectorized. The rectifiers plug into a rectifier shelf
assembly that accommodates a maximum of three individual 50
ampere rectifiers. The ECS plant can be equipped with a total of
fourrectifiershelf assembliesforatotal capacity of 12 SR Series
50 ampere rectifiers. (See the Lineage®2000 SR Series rectifier
product manual for additional information.)
Controller The ECS controller performs the centralized monitoring, control
and reporting functionsfor the ECSbattery plant. The basic ECS
controller can monitor and control up to 12 rectifiers. It also
provides a single interface point for power alarm and status
reporting.
Two optional expansion circuit packs are available to upgrade
the ECS controller: a microcomputer board equipped with a
powerful 16-bit microprocessor, and a datalogger board. The
microcomputer board adds sophisticated firmware features such
as remote communications, alarm history, and statistics. The
datalogger board may be used in conjunction with the
microcomputer option to provide general purpose ac and dc,
voltage and current monitoring and control. (See the ECS
controller manual for further information.)
Batteries The ECS Model H569-416 battery plant is compatible with
batteries with a short-circuit current rating less than 7000
amperes. For appropriate system loads and reserve times,
selection of the VR Series battery enables one to maximize space
efficiency and fully realize the benefits of front access, modular
growth, ease of installation and maintenance offered by the ECS
battery plant system design.

Lucent Technologies Lineage®2000 ECS Battery Plant H569-416
Issue 2 August 1996 Product Description 2 - 7
DC Distribution The ECS dc distribution is shown in Figure 2-3.The distribution
contains the plant charge and discharge bus bars, battery bus,
distribution bus, circuit breaker bus, positive and negative
rectifier bus, plant shunt, optional LVD/R contactor, fuse panel
and circuit breaker panels.
Distribution Bus
Bars The distribution bus bars include the charge return bus, discharge return bus, battery bus, LVD bus, distribution bus,
circuit breaker bus and positive and negative buses (See Figure
2-3). Battery strings are terminated to the battery bus and the
charge return bus. Negative rectifier outputs are routed to the
distribution circuit breakers through the negative rectifier bus,
the distribution bus and the circuit breaker bus. Positive rectifier
outputs are to the discharge return bus through the positive
rectifier bus, charge return bus and the plant shunt.
The load conductors are terminated on distribution strips above
the circuit breaker panels and the return conductors for load
circuits are terminated on the discharge return bus.
Plant Shunt A current shunt is a sensing device which provides a millivolt
signal proportional to the current flowing through it. The
millivolt-to-ampere ratio of the shunt is the dc resistance of the
shunt (in milliohms), which is thermally stable and accurately
known.
The current shunt in theECS Battery Plant is connected between
theChargeReturnBus andtheDischargeReturn Bus (see Figure
2-3). It is used to measure the total current supplied to the load
from the rectifiers and/or batteries. The shunt has a full scale
rating of 50 millivolts at the maximum plant current of 1200
amperes. The shunt millivolt signal is sent, via the CP5 Fuse
Board, to the controller where it is translated back to amperes
and displayed on the digital meter.
Low Voltage
Battery
Disconnect/
Reconnect (LVD/
R) Feature
To prevent costly battery damage due to deep discharges, the
ECS Battery Plant may be equipped with an optional automatic
battery disconnect. This disconnect is designed to isolate
batteriesfrom the load when the plant voltagereaches the lowest
usable battery voltage. The disconnect level is below the
operating range ofmostload equipment, in which case service to
the load would already have been lost. The disconnect does not

2 - 8 Product Description Issue 2 August 1996
separate the load circuits from the rectifiers, thus enabling the
rectifiers to begin powering the load as soon as ac power is
restored.
The LVD/R option consists of the LVD/R Contactor, circuitry
on the CP5 Fuse Board and associated wiring. Figure 2-4 is a
pictorial of the contactor (K1). The LVD circuit on CP5
monitors the plant charge bus voltage, designated RB. When the
RB voltage drops below a preset level, a comparator circuit on
the CP5 Fuse Board senses the low voltage condition and
removes power to the contactor. This opens the connection
between the battery buses and LVD bus, disconnecting the
batteries from the rectifiers and the load. The user has a choice
of disconnect threshold voltages (40.5 and 42.5 volts).
When the contactor is open and the rectifiers are not delivering
power, the controller is also unpowered. In this state, the
controller displays and LEDs are extinguished and various
alarms are issued to the alarm reporting center. (See the
Lineage®2000 Controller manual for further details.)
The red “LVD OPEN” and yellow “LVD FAIL” LEDs are
located on the front side of the dc distribution panel as shown in
Figure 2-5. The red “LVD OPEN” LED on the CP5 Fuse Board
is lit whenever the contactoris open, during a normal disconnect
or in the unlikely event of a contactor failure. The LVD sensing
circuitry on CP5is redundant. Afailure ofeither voltagedetector
circuit lights the yellow “LVD FAIL” LED, but the contactor
will stay closed. A Fuse Alarm Minor (MNF) is issued when a
LVD circuit fails, lighting a yellow LED on the controller front
panel and sending Power Minor (PMN) alarms to the alarm
reporting center.
Once the contactor opens it remains open until the RB voltage
again exceeds the set threshold voltage. Voltage does not return
until ac power is restored and the rectifiers restart. Once the
LVD circuit is energized, the LVD/R contactor closes the
circuit, allowing the batteries to be charged.
Distribution
Panels/Circuit
Breakers
Distribution Panels: The battery plant is equipped with three
distribution panels. Panels can accommodate up to 21 KS23616
circuit breakers each. Each bus bar in the panel is rated at 200
amperes in a 25°C ambient temperature. The unique plug-in
panel and circuit breaker design makes installation and growth a
snap.
