2000 ECS-6U Controller J85501E-1
Issue 4 August 1998
Product Description 2 - 17
Technologies manufactured ferroresonant or switched mode
technology rectifiers. All other rectifiers require field
termination to either a screw or wire wrap terminal.
Order Wire Board
The Order Wire Interface feature provides a means to access the
microprocessor board without the use of a dedicated telephone
line. This feature is a field installation kit ordered per J85501E-2
List H. It should be ordered when the controller will be
monitored over the FT-Series G embedded maintenance system
or a similar order wire system. The Microprocessor Board (CP2)
must be used along with the Order Wire Interface feature to
allow the interface between the modem and the FT-Series G
order wire circuit.
Additional equipment and connections are required outside the
controller to establish the communication link over the
FT-Series G embedded telemetry system (see Section 4,
“Optional 248A Order Wire Board”).
Circuit Options
Two other options, the Boost Charge Circuit and the Shunt
Isolator Circuit, are not part of the controller but can be used
with it in certain applications.
Boost Charge
Circuit
This circuit is approved for use only with Lucent Technologies
50 ampere or 25 ampere ferroresonant rectifiers in an FT-Series
G plant configuration of two or three rectifiers. This circuit
provides a feature that closely resembles the equalize function.
When used with the ECS-6U, the HV and EQ/HV must be set to
the same level on the 113A2. The BD must be at least 2.5 volts
below float in order to prevent false BD alarms.
The ED-83215-30 boost charge panel is designed to be used with
the ECS-6U controller in -48 volt applications. Its purpose is to
allow connected rectifiers to raise their output voltage so that
connected batteries can be charged at a voltage higher than their
normal float voltage. It is intended for use with rectifiers that do
not have the equalize feature.
The boost charge can be initiated or removed in three ways:
manually, by Switch S1 on the boost charge panel; manually, by
the Float/EQ switch on the front panel of the ECS-6U controller;
or remotely, via the microprocessor board of the ECS-6U. A
yellow LED lights on the front panel only when boost charge is
