The control will start automatically even if pro-
grammed for time-of-day start, delayed start, or push-
to-start operation. The SCR2000 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 #1-48) is not affected by a refresh
charge.
The charge termination 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 4
hours and 15 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 SCR2000
Control can be programmed to provide voltage-time
charge termination and disable the low current shut-
down feature for a limited number of charge cycles.
The number of cycles programmed in the control will
be decremented each time a charge complete con-
dition is reached. The number of forming cycles
selected can be from 0 to 30 charge cycles.
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.
Data Retention
— The SCR2000 Control uses
EEPROM memory for all data retention. A lithium
battery supports the time-of-day and day-of-week
circuitry. The lithium battery is only utilized during
AC power failures and will maintain date, time, and
data for a minimum of 10 years. Factory default
information is in EEPROM and has a minimum data
retention time of 10 years.
Time-of-Day Start –
The SCR2000 Control can be
programmed to delay the start of a charge cycle
until a specific time of day. Any time of day, in 1
minute increments, can be used for the time-of-day
start time. When a SCR2000 is programmed for
time-of-day start, and a battery is connected to the
charger, the programmed start time will be dis-
played. This feature can be used to save on energy
costs, provide a battery cool down period, or to pre-
vent opportunity charging.
Delayed Start
— The SCR2000 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 1 minute
increments, can be used for the delayed start
period.
When a SCR2000 is programmed for delayed start,
and a battery is connected to the charger, the
programmed 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 SCR2000 Control can
be programmed to disable the charger during a
specific time of day. The charger will turn off at the
beginning of the blockout period, and resume the
charge cycle at the end of the blockout period. Any
time of day, in 1 minute increments, can be used for
the time-of-day blockout period. When a SCR2000
is programmed for time-of-day blockout, and a
battery is being charged when the blockout period
occurs, the programmed end of blockout 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.
Manual Override of Programmed Start Modes –
A
SCR2000 Control, when programmed for time-of-day
start, delayed start, or time-of-day blockout, can be
manually overridden by pressing the “Enter” key
while the start of the charge cycle is being
automatically delayed by the control. This manual
override feature can be disabled through the “Start
Override” programming function. The manual
override feature allows the operator to start a charge
cycle immediately if a battery is needed sooner than
the programmed start time would allow.
Automatic Equalize –
The SCR2000 Control can be
programmed for two different types of automatic
equalize. SCR2000 controls are shipped from the
factory programmed to automatically provide an
equalize charge to every fifth complete charge cycle.
The number of cycles between equalize requests can
be varied from 0 to 30. If the SCR2000 is program-
med to automatically provide an equalize cycle every
zero cycles, then an equalize charge cannot be
requested manually and will never be provided
automatically. The second type of automatic
equalize mode is when an equalize charge is desired
on a particular day of the week. When programmed
for automatic equalize by day of week, the SCR2000
will provide an equalize charge to any battery which
is connected to the charger on the programmed
equalize day.
