DESCRIPTION OF EQUIPMENT
DESCRIPTION OF EQUIPMENT
Charger
The basic charging circuit is the silicon diode, rectifier-
type with ferroresonant transformer (s). This ferroreso-
nant transformer design regulates charging current by
allowing the battery to determine its own charge cycle
rate in accordance with its state of discharge. It pro-
vides a constantly-tapering charge that eliminates the
possibility of overcharging, even with line voltage varia-
tions of ± 10%. Three-phase input chargers have two
transformers. The charger is internally protected from
overload and short circuits.
When charging lead acid batteries, with the same
number of cells and ampere-hour capacity as shown
on charger nameplate, the charging time will be
approximately 8 hours. Batteries of smaller or larger
ampere-hour capacities can also be charged, but will
require shorter or longer charging, respectively.
Charge Control
The AC500 Control is provided as the standard charger
control. It utilizes either a voltage/time (VT) charge
termination or a patented pT/dV/dT charge termination
technique which eliminates excessive gassing by
returning approximately 107% of the amp-hours
removed from the battery.
Features of the AC500 Control include manual equal-
ize, manual stop, back-up timer protection, two charge
termination methods, 80% voltage point selection, high
and low battery voltage discrimination, and AC power
fail recovery.
The AC500 Control is “matched” to the output voltage
of the charger by means of a printed circuit board
mounted DIP switch. It will operate on 6, 12, 18, 24,
36, and “optional” cell batteries. “Optional” is provided
to accommodate batteries between 6 and 36 cells that
are not listed above.
The status of a normal charge cycle is indicated by the
four LEDs on the front panel. The “80% Charged” LED
will light when the battery voltage reaches the 80%
charged voltage. This voltage may be 2.37 volts/cell
or 2.45 volts/cell nominal, depending on the status of
DIP switch S1-7. See the AC500 Setup chapter of this
manual. The “Charge Complete” LED will light only if
the battery has completed the charge cycle and is
ready for use. The “Abnormal Shutdown” LED will light
if the charger terminates a charge prematurely. See
the Troubleshooting chapter of this manual to deter-
mine the cause of the fault. The “Equalize” LED will
light solid when a 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 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.
