1 Introduction
General
Information This product manual, Select Code 167-790-056, describes the
J85501E-2 ECS-12U Universal Rectifier Controller. The basic
ECS-12U controller monitors and controls any combination of
up to 12 Lucent Technologies switchmode (SR) or ferroresonant
rectifiers and provides a single interface point for power alarm
and status reporting. When ordered with the optional
microprocessor and datalogger features, it adds the latest
technology in the product line to the battery plant.
When used with the optional Rectifier Adapter Board (RAB),
the ECS-12U controller allows rectifiers of various
technologies, vintages, and vendors to be tied together in the
same battery plant and can be used for retrofit applications in
older Lucent Technologies battery plants such as the 302 series
or the 326 series. It can also be used to replace older technology
controllers in other vendors' battery plants. Upgrading can be
accomplished by placing the controller in a supplemental bay or
in the same bay as the original equipment.
Appendix A is a list of the various Lucent Technologies
rectifiers, both J- and KS-coded, that have the automatic restart
feature and are compatible with the ECS-12U.
The ECS-12U demonstrates Lucent Technologies' continuing
dedication to providing state-of-the-art energy systems
management products for all battery plants, both old and new.
The Lineage®2000 Battery Plant product line is designed to
provide battery-backed common system office voltages of
+24Vdc, -24Vdc, or -48Vdc in telecommunications
applications.
The ECS-12U controller is shown in Figure 1-1. A view of a
typical ECS controller application is shown in Figure 1-2.

Lucent Technologies Lineage®2000 ECS-12U Controller J85501E-2
2 - 4 Product Description Issue 3 July 1998
Basic
Controller The basic ECS-12U controller monitors and controls any
combination of up to twelve Lucent Technologies switchmode
(SR) or ferroresonant rectifiers and provides a single interface
point for power alarm and status reporting. Equipped with a
113B Control Unit, two RIBs, and an LVD/Fuse Board or Fuse
Alarm Board, the basic controller performs the traditional
analog control functions of the MCS, CCS, or XCS controllers.
Each of these functions is described in detail in the paragraphs
that follow.
Operating
Voltage The controller is powered by the plant dc voltage and may be
used in 24V or 48V plants. It may be powered from either
positive ground systems, e.g., -48V,or negative ground systems,
e.g., +24V. Movable jumpers located on the upper backplane
and DIP switches located on the 113Band the Rectifier Interface
Boards (RIB) must be positioned according to the plant voltage.
The 113B may be plugged directly into the ECS-12U controller
when the backplane is properly configured.
Batteryless
Operation The ECS-12U controller is suitable for telecommunications
power plants with or without batteries. In batteryless plants, the
loss of ac power causes an immediate loss of dc power to the
controller. When ac power is restored, the ECS-12U controller,
in an unpowered state, allows the rectifiers to automatically
restart.

IMPORTANT When the controller loses power, it also loses the ability to
detect alarm conditions in the plant. To prevent the danger
of unreported alarms, Power Major and Power Minor
alarms are automatically issued when the controller is
powered down.
IMPORTANT Not all rectifiers will perform properly without a battery.
Consult your rectifier manual.
Rectifier Sense
Leads Separately fused sense leads run from the LVD/Fuse Board to the rectifiers via the controller backplanes. These leads are not
interrupted when the 113B is removed. The rectifiers use the
sense leads to maintain the plant bus voltage independently of
any load-dependent voltage drop between their output terminals
and the bus.
Office Alarm
Contacts and
Alarm Battery
Supply
Alarm contacts are provided on the 113B that may be connected
to the office alarm system by the installer. (See Section 4,
“Wiring.”) Each set of contacts is a Form C or transfer type, i.e.,
a combination of normally open and normally closed contacts
with one side of each in common. The normally open contact is
referred to as O (other applications may call this the NO
contact). The normally closed contact is referred to as C (other
applications may call this the NC contact). The common or
return contact is referred to as R (other applications maycall this
the C contact). Each Form C set is isolated. An alarm set is
provided for each type of alarm condition, as follows:
AC Failure (ACF)
Major Fuse Failure (MJF)
Minor Fuse Failure (MNF)
High Voltage (HV)
Battery on Discharge (BD)
Low Voltage Battery Disconnect (LV)
In addition, alarms that are classified as Major or Minor cause a
group of general-purpose Major or Minor alarms, as follows:
Power Major - Visible (PMJV)
Power Major - Audible (PMJA)
Power Major - External (PMJE)
Power Minor - Visible (PMNV)
Power Minor - Audible (PMNA)
Power Minor - External (PMNE)

Lucent Technologies Lineage®2000 ECS-12U Controller J85501E-2
2 - 6 Product Description Issue 3 July 1998
The de-energized or alarm state of the relay is its normal state,
i.e., a closure exists between the “C” and “R” poles and an open
exists between the “O” and “R” poles.
All alarms are in the non-alarm state only when the control unit
is powered and the corresponding alarm is not present. When an
alarm occurs, the corresponding closure occurs. When the
control unit loses power, all alarms are issued.
An Alarm Battery Supply (ABS) and a ground return are
available on oneof the terminal blocks(TB101). These pins may
be wired by the installer to one or more alarms on the terminal
blocks to drive alarm lamps, buzzers, or remote relays in the
office alarm system. ABS is the same voltage as the plant bus
voltage and is separately fused on the fuse board.
Battery on
Discharge Alarm If rectifier output isinsufficient to supply the load current forany reason (such as an ac power failure), the battery reserve will
provide the necessary current. Such a battery discharge can be
detected by a drop in the plant bus voltage. Whenever the plant
voltage drops below a preselected threshold, the controller
issues a Battery on Discharge (BD) alarm and lights a red LED
onthe controllerfrontpanel.Thisalarmthresholdistypically set
to indicate the onset of battery discharge to allow enough time
for maintenance personnel to respond before battery reserve is
exhausted. When a BD alarm occurs, service is not usually
affected immediately. However, since attention is required in a
limited time, BD is considered a Major alarm, and all three
Power Major alarm groups are issued to the office alarm system
when a BD occurs.
It should be noted here that a BD alarm does not necessarily
indicate that rectifier output current has been lost or reduced. A
BD alarm can be caused by misadjusted rectifier output voltage
during otherwise normal operation. It can also be caused by
current overload on normally functioning rectifiers.
The voltage threshold for theBD alarm is selected by the userby
setting a group of DIP switches on the 113B. The setpoint is
typically at least 1 volt below the plant float voltage for nominal
48V plants or 0.5 volts below the float voltage in 24V systems.
This threshold avoids nuisance alarms due to component
tolerances, variations in load, and other transient conditions.

Lucent Technologies Lineage®2000 ECS-12U Controller J85501E-2
Issue 3 July 1998 Product Description 2 - 7
The actual BD threshold settings that may be selected are listed
on Figure 4-5 and on a label on the controller itself. Therange of
available settings is based on the most common battery float
voltages for 24V and 48V systems. The shutdown level can be
adjusted in 0.5 volt increments.
Selective High
Voltage
Shutdown
The controller is equipped to detect a high voltage condition on
the plant bus. Such a high voltage condition is typically caused
by lightning-induced transients on the commercial ac power
lines. A rectifier failure might, however, cause an individual
rectifier to increase its output voltage. To prevent high voltage
from damaging the connected telecommunications load, the
controller will send a signal for the rectifiers to shut down if the
plant voltage goes high.
When the controller detects an increase in the plant voltage
above a preset threshold, it immediately issues an HV alarm to
the external alarm system. HV is considered a Major alarm, so
all Power Major alarm groups are also issued.
If the rectifiers do not have load sharing, the controller sends a
simultaneousshutdownsignaltoallrectifierswhile reportingthe
alarm.Sincethe output ofall rectifiers are paralleledin theplant,
their output voltages are forced to be the same. Their output
currents, however, may vary widely. In a high voltage condition
caused by an individual rectifier failure, the failed rectifier will
be supplying more current than any other rectifier. When the
high voltage shutdown signal is sent by the controller, any
Lucent Technologies rectifier supplying more than 10% of its
rating, i.e., the failed rectifier, will shut down, causing the plant
voltage to drop to normal and the HV alarm to retire. All other
rectifiers will remain on. If a high voltage condition exists
without an individual rectifier failure, e.g., because of incorrect
setting of the HV-threshold DIP switches or lightning-induced
high voltage, all Lucent Technologies rectifiers supplying more
than 10% of their rated current will shut down. The detection of
the high voltage condition and sending of the shutdown signal
are functions of the controller, while the selection of the
rectifier(s) with more than 10% rated current for shutdown is a
function of the rectifiers.
Ifthe rectifiers have load sharing, the HVshutdown mayoperate
differently. In the Lucent Technologies SR series, if a single
rectifier fails, its output current will try to increase and the HV
signal will shut down only that rectifier. If the entire bus goes
