OPERATION
WARNING: DO NOT connect a battery
to this charger if any LED is lit. Do not
disconnect a battery from this charger
while a charge is in progress; otherwise,
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.
Manual Stop
1. To turn the charger off during any part of a charge
cycle, press the STOP key. All four LEDs will flash.
2. To restart the charger, disconnect and reconnect the
battery. A new charge cycle will begin.
Battery Discrimination
The AC1000 Control has the ability to reject batteries
with cell sizes that do not match the cell size that the
control is set up for (via DIP switch S2 - 1 through S2 - 6).
If the battery connected to the charger has an average
terminal voltage of greater than 2.30 volts/cell, the
charger will not start and all 4 LEDs will flash, then the
“ Charge in Progress ” LED will flash (high battery fault
indication). If the battery voltage eventually falls below
2.30 volts/cell, the control will begin a normal charge
sequence.
If the battery connected to the charger has an average
terminal voltage of less than 1.75 volts/cell, the charger
will not start and all 4 LEDs will flash, then the “80%
Charged ” LED will flash (low battery fault indication). If
the battery voltage eventually rises above 1.75 volts/
cell, the control will start a normal charge sequence.
If the battery connected to the charger has a terminal
voltage of less than 1.75 volts/cell and the operator
wishes to start the charge regardless of this low battery
voltage, the charge cycle will start if both the
EQUALIZE and the STOP keys are held pushed in until
all LEDs go out (approximately 5 seconds). Release
the key at this time.
Refresh Charge
In order to guarantee that a fully charged battery is
always ready for use, a “ Refresh ” feature has been in-
corporated into the AC1000 Control. If a battery is
left connected to the charger for 72 hours after a
“ Charge Complete ” has been reached, the AC1000 will
start a charge sequence. The running time of this
“ Refresh ” charge will depend on the depth of self -
discharge of the battery.
Backup Timer Shutdown
A backup timer will shut down the charger and all 4
LEDs will flash then the “ Charge Complete ” LED will
flash if the battery on charge does not reach the 80%
voltage during the first 10 hours of charging.
Likewise, if the AC1000 Control is set to terminate via
the pT/dV/dT methodology (DIP switch S1 - 2 set to
DVDT) and the charger does not reach the termination
point within 5 hours after reaching the 80% charged
voltage, all 4 LEDs will flash then the “ Charge Com-
plete ” LED will flash.
WARNING: DO NOT connect a
battery to this charger if any LED
is lit. Do not disconnect a battery
from this charger while a charge
is in progress. Otherwise, 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
