2000 ECS-12U Controller J85501E-2
4 - 12 Installation and Setup Issue 3 July 1998
shutdown levels are approximately 1.0 volt above operating
voltage for nominal 48-volt plants or approximately 0.5 volt
above operating voltage for nominal 24-volt plants.
The actual operating voltages in float and equalize modes are
determined by the battery manufacturer's recommendations and
by any restrictions imposed by the load equipment.
DIP switches must be set for the proper plant operating voltage
(24 or 48 volts). All DIP switches must be set for the same
operating voltage. The switch settings may be done as part of the
BD and HV level setting procedures in this section, respectively.
See the DIP switch setting instructions in “Controller Setup.”
For batteryless plants, disable equalize and use a 3-volt margin
for the HV setting on 48-volt plants and a 1.5-volt margin for the
HV setting on 24-volt plants.
Rectifier Port

The ECS-12U controller is factory configured for use with
Lucent Technologies Lineage
®
2000 ferroresonant rectifiers,
J855 series. Rectifier connections should be made to the
respective ports on the lower backplane. (See Figure 4-8.) Two
Rectifier Interface Boards (RIBs) are provided with the
controller. The lower RIB is associated with rectifier ports 1-6.
The upper RIB is associated with rectifier ports 7-12.
To connect rectifiers to the controller, set switch S3 on the two
Rectifier Interface Boards (RIBs). (See Figures 4-6 and 4-7.)
Following the table shown in Figure 4-7, set the switch at the
position corresponding to each rectifier port to ON (closed) for
each ferroresonant rectifier connected to the ECS-12U
controller. For each port not used or where a Lucent
Technologies switchmode rectifier (SR) is used, set the
respective switch position to OFF (open) on switch S3. The same
table of settings shown in Figure 4-7 also appears as a label on
the inside of the door of the controller. Table 3-B lists standard
interface cables. These control cables are ordered separately
from the controller with individual cable length specified in job
specifications.
