Energy Solutions 24VDC Battery Charger Model 12R1050E3D
Workhorse Series 2
Energy Solutions 24VDC Battery Charger has
been tested and is in good working condition. The SERIES
2 Industrial Battery Chargers are
full wave silicon rectified ferroresonant chargers.
Charging current is regulated by the ferroresonant
transformer(s). The ferroresonant transformers allow
the battery to determine its own charge rate with
respect to its state of discharge. The controllers
are custom dv/dt-di/dt termination PCB assemblies
for flooded lead-acid battery chargers. A solid state,
pre-programmed microcomputer provides total control
of charge termination, preventing both undercharging
and overcharging. The microcomputer incorporates
built-in fault detection to ensure correct battery
connection and smooth operation. The charge is terminated
automatically when the control determines that the
battery is fully charged.
five-second delayed start upon
connection of a proper sized, good battery.
voltage sensing determines if
there is a proper sized battery connected
to the charger. This prevents charging
if there is a bad battery connected, no
battery connected, bad battery-to-charger
connection or battery voltage and charger
voltage and current are continuously monitored.

12-hour “REFRESH” adds
a top off charge to a fully charged battery.
The charger will start a “refresh” charge
12 hours after a normal charge complete
has been reached, assuming that the battery
was not disconnected during that time.
Timers prevent extended charging
of a damaged battery. The first timer starts
at the beginning of the charge cycle and
runs for 9 hours. At 9 hours, if the battery
has not reached the 80% point, the charger
will shutdown. The second timer starts
at the 80% point and runs for 6 hours.
If the charger does not terminate by then
it will shutdown.
Shutdown Lockout will not allow
a charge to start after a manual or problem
shutdown occurs. Automatic Shutdown Lockout
is cleared after the “Shutdown” battery
is disconnected. This allows a charge to
begin upon connection of a good, proper
shutdown occurs for any of five
code “Lo U” – Low volts
per cell – the battery voltage
is less than 1.7 vpc. The charger will
not be “locked off”. The
charger will automatically start charging
when the battery voltage is greater than
code “Hi U” – High
volts per cell – greater than 2.8.
code “dISC” – Battery
disconnected from charger during charge.
code “dur” – Charge
time exceeded - backup timer expired.
code “Lo I” – Low charging
current – charging current less than
approximately 3 amps
STOP switch - Will stop the charger
from charging. The display will indicate “OFF” until
the battery is disconnected. When pressed
with no battery connected displays the delay
to nine-hour programmable delayed start thumb
wheel switch. This rotary switch
can be set from 0 to 9 hours to delay the
start of charge.
Automatic Equalization Cycle every 5th cycle. This
option is enabled by removing “W1” on
the control PC board. For a completed charge
cycle to be counted, the battery must be
on charge at less than 80% for 1 hour or
more from start of charge.
switch - This switch when depressed
will turn on and off the three hour additional
manual equalizing charge. When the Equalize
function is turned on, an “E” will
be displayed in the leftmost digit of the
display. The “E” will flash during
the actual equalize charge cycle (manual
and automatic). If Auto-Equalize has been
selected, pressing this switch prior to connecting
the battery will allow the number of charge
cycles remaining before auto-equalize cycle
to be displayed in the format ‘E-#.’
- “ CHARGING” -
charger is charging the battery.
- “ 80%” -
the battery voltage is greater than 2.37
volts per cell.
- “ CHARGE
COMPLETE” - the charge cycle has
been terminated normally.
- “ SHUTDOWN” -
the unit has shut down for a fault.
Voltage Selection, factory set at
2.37 volts per cell. This may be changed
to 2.45 volts per cell by removing “R32” on
the PC control board assembly.
