EC2000 CONTROL FEATURES
type batteries, which are in storage or inactive for
long periods to replace losses due to limited action
and to insure that every cell is brought periodically
to a full state of charge. The EC2000 Control has an
adjustable 8 to 99 hour refresh charge timer
(programmed through the “Refresh Delay” function)
which starts with a normal charge complete, either
DV/DT or voltage time. If a battery is left connected
to the charger for the Programmed number of hours
after a charge complete, the control will automatical-
ly begin a refresh charge cycle. The control will start
automatically even if programmed for time-of-day
start, delayed start or push-to-start operation. The
EC2000 will not start the charge cycle during a time-
of-day blockout period. It will automatically request
an equalize cycle if it is programmed to equalize on
that day. Charge cycle data (Functions #1-50) is not
affected by a refresh charge. The charge termina-
tion technique for a refresh charge will be DV/DT
regardless of how the control is user programmed,
and the 0-80% back-up timer will be four hours and
fifteen minutes during a refresh charge. This feature
will insure that any battery left connected to the
charger for extended periods of time will not be
damaged due to self-discharge, and will be kept in a
fully charged state.
Finish Cell Forming Feature — The EC2000
Control can be programmed to provide voltage-time
charge termination and disable the low current
shutdown feature for a limited number of charge
cycles.
The number of cycles programmed into the Forming
Cycles function will be forming cycles and that
number will be decrement each time a charge com-
plete condition is reached. The number of forming
cycles selected can be from 0 to 30 charge cycles.
Input Kilowatt Hour Feature — The Control will
calculate the approximate input kilowatt hour usage
for each charge cycle. This feature may be helpful
in determining the cost of charging given various
charging scenarios with known electricity costs.
80% Charged Point — A standard EC2000 Control
will light the “80% Charged” LED and enable the
charge termination routine when the battery voltage
reaches the gassing voltage and the charging has
decreased below start current. The gassing voltage
is nominally 2.40 volts/cell and is adjusted automati-
cally when the charger output voltage is modified to
charge batteries of different temperatures.
Data Retention — The EC2000 Control uses 2
types of electronic memory for data retention. Real
time clock data is kept current by a non user re-
placeable lithium battery in the absence of AC pow-
er. All other program memory and charge cycle
information is resident in non-volatile memory. The
minimum data retention time should be at least 10
years.
Time-of-Day Start — The EC2000 Control can be
programmed to delay the start of a charge cycle
until a specific time of day. Any time of day, in one
minute increments, can be used for the time-of-day
start time.
When a EC2000 is programmed for time-of-day
start, and a battery is connected to the charger, the
programmed start time will be displayed. This fea-
ture can be used to save on energy costs, provide a
battery cool down period, or to prevent opportunity
charging.
Delayed Start — The EC2000 Control can be
programmed to delay the start of a charge cycle for
a specific period of time. Any time period from 1
minute to 23 hours and 59 minutes, in one minute
increments, can be used for the delayed start peri-
od.
When a EC2000 is programmed for delayed start,
and a battery is connected to the charger, the pro-
grammed delay time will be displayed.
The time displayed will be decremented once per
minute so that the time displayed is always the
amount of time remaining before the start of charge.
This feature can be used to save on energy costs,
provide a battery cool down period, or to prevent
opportunity charging.
Time-of-Day Blockout — The EC2000 Control can
be programmed to disable the charger during a spe-
cific time of day. The charger will turn off at the be-
ginning of the block-out period, and resume the
charge cycle at the end of the block-out period. Any
period of time of day, in one minute increments, can
be used for the time-of-day block-out period. When
a EC2000 is programmed for time-of-day block-out,
and a battery is being charged when the block-out
period occurs, the programmed end of block-out
time will be displayed. This feature can be used to
save on energy costs, provide a battery cool down
period, or to prevent opportunity charging.
WARNING: Enabling the Finish Cell
Forming feature will cause the charger to
continue to run for a period of time if the
battery has been disconnected before
Charge Complete or pressing the Manual
Stop key. This condition will continue
until the programmed number of cycles
have been completed. The battery
should never be disconnected while a
charge is in progress.
