Description Of Equipment - AMETEK/PRESTOLITE POWER AC1000 Control Owner's Manual

DESCRIPTION OF EQUIPMENT

Charger
The basic charging circuit is the silicon diode,
rectifier-type with ferroresonant transformer (s). This
ferroresonant transformer design regulates charging
current by allowing the battery to determine its own
charge cycle rate in accordance with its state of
discharge. It provides a constantly-tapering charge that
eliminates the possibility of overcharging, even with line
voltage variations of ± 10%. Single-phase input
chargers have one transformer, three-phase input
chargers have three. 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 AC1000 Control is provided as the standard
charger control. It utilizes either a voltage/time (VT)
charge termination or a patented pT/dV/dT charge ter-
mination technique which eliminates excessive gassing
by returning approximately 107% of the amp-hours
removed from the battery.
Features of the AC1000 Control include manual
equalize, 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.

DESCRIPTION OF EQUIPMENT
The AC1000 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 AC1000 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 determine 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.
