Description Of Equipment; Ec2000 Control - Ametek ECLIPSE II Owner's Manual

DESCRIPTION OF EQUIPMENT

The basic charging circuit is the mosfet inverter high
frequency-type with isolating transformer (s). This
design regulates charging current by allowing the
battery to determine its own charge cycle rate in
accordance with its state of discharge. It provides a
constant current-constant voltage-constant current
(IEI) charge that eliminates the possibility of over-
charging, even with line voltage variations of ± 10%
and allows the battery to finish at the proper current
regardless of battery age or gravity type.
The Eclipse II provides battery charging over a
wide range of environmental conditions. The
charger will precisely charge your battery based
on battery temperature, type, and size; by automati-
cally adjusting its own output charge characteristic
within the power limits of the chargers power circuit.
Figure 3-1
When applied with the Prestolite Power optional
Battery Identification Module (BID), the Eclipse II
identifies a battery selected for charging at the time
of connection and adjusts its output for that specific
battery. During the charge cycle, or duration of
connection, the Eclipse II continuously monitors the
battery's temperature via the BID and adjusts its
output to match the battery temperature as it
changes throughout the charge cycle.
Upon connection of the battery, the Eclipse II reads
the information programmed into the BID and identi-
fies the battery's AH rating, cell size, type of
construction, electrolyte temperature, and pro-
grammed method of charge and adjusts its output
curve based on this information.
The Eclipse II is internally protected against
overload and short circuits by both input and output
fusing, plus Prestolite's unique curve monitoring
circuit periodically measures the output curve to
ensure that the voltage and current are within the
limits set at the factory.

DESCRIPTION OF EQUIPMENT
Charger Control
The EC2000 is the standard charge control for the
Eclipse II. It utilizes either a voltage/time (VT)
charge termination or a patented dV/dT charge
termination technique which eliminates excessive
gassing returning approximately 107% of the amp
hours removed from the battery. Features of the
EC2000 Control include auto start/stop, manual
equalize, manual stop, back-up timer protection, two
charge termination methods, manual or automatic
(with optional BID module) battery temperature
compensation, AC power fail recovery, selectable
output profiles, and charge cycle data archiving.
The backlit 2x20 LCD display and four bright LEDs
on the front panel indicate the status of a normal
charge cycle. The ―80% Charged‖ LED will light
when the battery current is reduced to approxi-
mately 8.2 amps per 100 AH of battery rating. The
battery voltage at the 80% charged point will vary
with charge profile setting and/or manual or auto-
matic temperature settings. The ―Charge Complete‖
LED will light only if the battery has completed the
charge cycle and is ready for use. All four LEDs will
flash if the charger terminates a charge prematurely.
See the Troubleshooting chapter of this manual to
determine the cause of the fault. The ―Equalize‖
LED will light solid when an equalize charge is
requested by pressing the equalize push button.
The ―Equalize‖ LED will flash when the charger is
equalizing the battery.
WARNING: Do not connect a
battery to this charger if any lamp
is lit. Do not disconnect a battery
from this charger while a charge
is in progress. Otherwise, damage
to charger, arcing and burning of
connector parts or a battery
explosion may result. Batteries
produce explosive gases. Keep
sparks, flame, and cigarettes
away. Ventilate when charging
in an enclosed area. Always shield
eyes when working near batteries.
