status and alarm signals. The SR Series 100 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
100 ampere rectifiers. The ECS plant can be equipped with four
rectifier shelf assemblies for a total capacity of 12 SR Series 100
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 functions for the ECS battery 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 battery plant is compatible with all flooded and valve
regulated batteries which accept float voltages within the range
of 24 to 29 Vdc. 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. For systems requiring higher
capacities and/or longer reserve times, the Lineage

2000
Round Cell or Unigy
®
II series of batteries are appropriate.
DC Distribution
The ECS dc distribution is shown in Figure 2-2. 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.
