SAFETY INSTRUCTIONS AND WARNINGS
SAFETY INSTRUCTIONS AND WARNINGS
FOR OPERATION OF BATTERY
CHARGING EQUIPMENT
IMPORTANT – READ AND
UNDERSTAND THESE
INSTRUCTIONS. DO NOT
LOSE THEM. ALSO READ
OPERATING/INSTRUCTION
MANUAL BEFORE
INSTALLING, OPERATING,
OR SERVICING THIS
EQUIPMENT.
A. General
Battery charging products can cause serious
injury or death, or damage to other equipment or
property, if the operator does not strictly observe
all safety rules and take precautionary actions.
Safe practices have developed from past experience
in the use of charging equipment. These practices
must be learned through study and training before
using this equipment. Anyone not having
extensive training in battery charging practices
should be taught by experienced operators.
Only qualified personnel should install, use, or
service this equipment.
B. Shock Prevention
Bare conductors, or terminals in the output circuit,
or ungrounded, electrically-live equipment can
fatally shock a person. To protect against shock,
have competent electrician verify that the
equipment is adequately grounded and learn what
terminals and parts are electrically HOT.
The body’s electrical resistance is decreased when
wet, permitting dangerous current to flow through the
body. Do not work in damp area without being
extremely careful. Stand on dry rubber mat or dry
wood and use insulating gloves when dampness or
sweat cannot be avoided. Keep clothing dry.
1. Installation and Grounding of Electrically Powered
Equipment – Electrical equipment must be installed
and maintained in accordance with the National
Electrical Code, NFPA 70, and local codes. A
power disconnect switch must be located at the
equipment. Check nameplate for voltage and
phase requirements. If only 3-phase power is
available, connect single-phase equipment to only
two wires of the 3-phase line. DO NOT CONNECT
the equipment grounding conductor (lead) to the
third live wire of the 3-phase line as this makes the
equipment frame electrically HOT, which can cause
a fatal shock.
If a grounding lead (conductor) is part of the power
supply cable, be sure to connect it to a properly
grounded switch box or building ground. If not part
of the supply cable, use a separate grounding lead
(conductor). Do not remove a ground prong from
any plug. Use correct mating receptacles. Check
ground for electrical continuity before using
equipment.
The grounding conductor must be of a size equal
to or larger than the size recommended by Code or
in this manual.
2. Charging Leads – Inspect leads often for damage
to the insulation. Replace or repair cracked or worn
leads immediately. Use leads having sufficient
capacity to carry the operating current without
overheating.
3. Battery Terminals – Do not touch battery terminals
while equipment is operating.
4. Service and Maintenance – Shut OFF all power at
the disconnect switch or line breaker before
inspecting, adjusting, or servicing the equipment.
Lock switch OPEN (or remove line fuses) so that
the power cannot be turned ON accidentally.
Disconnect power to equipment if it is to be left
unattended or out of service.
Disconnect battery from charger.
Keep inside parts clean and dry. Dirt and/or
moisture can cause insulation failure. This failure
can result in high voltage at the charger output.

SAFETY INSTRUCTIONS AND WARNINGS
2-2 April 28, 1999
C. Burn and Bodily Injury Prevention
The battery produces very high currents when short
circuited, and will burn the skin severely if in contact
with any metal conductor that is carrying this current.
Do not permit rings on fingers to come in contact with
battery terminals or the cell connectors on top of the
battery.
Battery acid is very corrosive. Always wear correct
eye and body protection when near batteries.
D. Fire and Explosion Prevention
Batteries give off explosive flammable gases which
easily ignite when coming in contact with an open
flame or spark. Do not smoke, cause sparking, or
use open flame near batteries. Charge batteries only
in locations which are clean, dry, and well ventilated.
Do not lay tools or anything that is metallic on top of
any battery. All repairs to a battery must be made
only by experienced and qualified personnel.
E. Arcing and Burning of Connector
To prevent arcing and burning of the connector
contacts, be sure the charger is OFF before
connecting or disconnecting the battery. (If the
charger is equipped with an ammeter, the ammeter
should not indicate current flow.) Always connect
battery before turning charger ON.
F. Medical and First Aid Treatment
First aid facilities and a qualified first aid person should
be available for each shift for immediate treatment of
electrical shock victims.
EMERGENCY FIRST AID: Call
physician and ambulance
immediately. Use First Aid
techniques recommended by the
American Red Cross.
DANGER: ELECTRICAL SHOCK
CAN BE FATAL. If person is
unconscious and electric shock
is suspected, do not touch
person if he or she is in contact
with charging leads, charging
equipment, or other live electrical
parts. Disconnect (open) power
at wall switch and then use
First Aid. Dry wood, wooden
broom, and other insulating
material can be used to move
cables, if necessary, away from
person. IF BREATHING IS
DIFFICULT, give oxygen. IF NOT
BREATHING, BEGIN ARTIFICIAL
BREATHING, such as mouth-to-
mouth. IF PULSE IS ABSENT,
BEGIN ARTIFICIAL CIRCULATION,
such as external heart massage.
IN CASE OF ACID IN THE EYES, flush very well
with clean water and obtain professional medical
attention immediately.
G. Equipment Warning Labels
Inspect all precautionary labels on the equipment.
Order and replace all labels that cannot be easily read.

INITIAL SET-UP & DESCRIPTION
Set-Up
See Location Diagram of Selector Switches included in
this manual.
For proper operation, the AC500 Control must be set to
match the charger in which it is installed.
Cell Size Selection
From the data plate on the charger, note the number of
cells. Place the corresponding DIP switch (S1) on the
AC500 Control in the “ON” position.
S1-1 6 Cells
S1-2 12 Cells
S1-3 18 Cells
S1-4 24 Cells
S1-5 36 Cells
S1-6 Unique Part Number
Only one of the above DIP switches should be in the
“ON” position at any one time.
80% Charged Voltage
Switch S1-7 can be used to adjust the 80% charged
voltage.
Termination Type
Switch S1-8 can be used to select either dV/dT charge
Termination or VT.
Description
AC500 without Ammeter
The AC500 Control uses a single chip microcontroller
to both monitor and control the battery charging proc-
ess.
The user is kept up-to-date on the progress of the
charge cycle by the four LED’s on the front panel of the
control (See Page 6-1). The AC500 Control utilizes
either a Voltage/Time (VT) charge termination or a
patented dV/dT charge termination technique which
eliminates excessive gassing by returning approxi-
mately 107% of the amp-hours removed from the
battery. All front panel information (including operating
instructions) is back printed on a polycarbonate overlay
which is resistant to damage from oils, gasoline, and
frequent operator handling. The AC500 Control is
“matched” to the output voltage of the charger by
means of a printed circuit board mounted DIP switch
(See Figure 4-1). Features of the AC500 Control
include auto start/stop, auto/manual equalize, manual
stop, backup timer protection, two charge termination
methods, 80% voltage point adjustment, high and low
battery voltage discrimination, 72 Hour Refresh, and
AC power fail recovery.
AC500 with Ammeter
The AC500 with ammeter is identical to the AC500
described above, except for the inclusion of an analog
ammeter. The ammeter provides an accurate
indication of the DC charging current at all times.

OPERATION
Normal or Daily Charge
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.
1. Insure that battery size matches charger (Number of
cells and ampere hour capacity are within nameplate
information).
2. Securely engage the battery and charger connec-
tors.
3. After a five second delay (all LED‘s will be lit), the
charger will turn on. The “Charge in Progress“ LED
will indicate charging current.
4. The “80% Charged” LED will light when the battery
on charge reaches the 80% charged voltage.
5. The charger will automatically turn off and the

has finished. The light will remain on until the
battery is disconnected from the charger.
NOTE: To disconnect battery from charger before
charge is complete, first press the stop key,
then disconnect the battery from
the charger.
Equalize or Weekend Charge
The AC500 features Auto Equalize every fifth charge
cycle. Closing S1-9 disables the auto equalize feature;
and an equalize charge request can be performed by
pressing the “Equalize” push-button on the control front
panel. When Auto Equalize is enabled (S1-9 is open),
then the “Equalize” push-button can not be used to
request an equalize charge. The AC500 is shipped
with auto equalize feature enabled. With auto
equalize disabled, an equalize charge can be selected
or de-selected for any charge cycle using the sequence
below.
1. Insure that battery size matches the charger.
(Number of cells and ampere-hour capacity are
within charger nameplate rating.)
2. Securely engage the battery and charger
connectors.
3. After a 5 second delay (all LED’s will be lit), the
charger will turn on. The “Charge In Progress”
LED will indicate charging current.
4. Press the “Equalize” key. The “Equalize” LED
will light solid. Press the key again to cancel
the equalize charge.
NOTE: The equalize charge cannot be cancelled
once the battery reaches the equalize

to terminate the charge.
5. The “80% Charged” LED will light when the battery
on charge reaches the 80% charged voltage.
6. The battery reaches the normal termination point
(dV/dT or VT). However, the battery is charged
another 3 hours. The “Equalize” LED will flash
during this equalize period.
7. The charger will automatically turn off, and the
“Charge Complete” and the “Equalize” LED will
light when the equalized charge has finished. The
LED’s will remain on until the battery is
disconnected from the charger.
September 7, 2000 Revised 5-1

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 AC500 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 S1-1 through S1-6).
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 keys at this time.
Refresh Charge
In order to guarantee that a fully charged battery is
always ready for use, a “Refresh” feature has been
incorporated into the AC500 Control. If a battery is left
connected to the charger for 72 hours after a “Charge
Complete” has been reached, the AC500 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 AC500 Control is set to terminate via
the dV/dT methodology (DIP switch S1-8 off) 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 Complete” 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
eyes when working near batteries.

OPERATION
April 28, 1999 5-3
Battery Disconnect Shutdown
If the battery is disconnected from the charger during a
charge cycle, the charger will be shut down. All LEDs
will be off.
Low Current Shutdown
If the charger output current falls below a predeter-
mined level, a low current shutdown will occur. All 4
LEDs will flash, then the “Equalize” LED will flash.
AC Power Failure
During an AC power failure, the AC500 Control stores
key information about the charge cycle. The informa-
tion is retained by powering some of the control’s key
components with a battery derived power supply. This
causes the control to resume the charge where it left off
when the AC power is returned, unaffecting timers
and equalize requests.

TROUBLESHOOTING
6-1 April 28, 1999
193111-035
TROUBLESHOOTING
If a problem is suspected with the AC500 Control,
always check that the cell selection switch on the side
of the control is set correctly (see Location Diagram on
page 4-1). An improperly set cell selection switch could
cause the charge to end prematurely or to run too long
resulting in an abnormal shutdown.
Also, an improperly connected or faulty control wire
harness could cause erratic operation. Inspect the
control wire harness connections for proper mating and
that all wire/terminals are fully installed in the connector
housing (s). For detailed charger troubleshooting
procedures, see the Charger Manual.
WARNING: ELECTRICAL SHOCK HAZARD — Before checking electrical
components, turn off and remove fuses of disconnect switch (supplying
AC power to charger), disconnect battery, and check for voltage on
capacitors. Discharge through insulated screwdriver if there is any
reading.

TROUBLESHOOTING
6-3 April 28, 1999
6.01 Repeated manual disconnecting of the battery from the charger before charge complete can cause long
term battery damage and lead to inefficient truck/battery/charger operations. When it is necessary to stop
the charge cycle before charge complete, always terminate the charge cycle by pressing the STOP key
before disconnecting the battery from the charger.
6.02 To check the Control Board for proper operation, first check the DIP Switch settings of S1. Make sure the
the proper cell size is set to match the charger.
6.03 Take “Specific Gravity” readings and measure “Cell Voltages”. If acid has been spilled or the battery has
been extremely heated, it is possible that a battery’s capacity could be greatly reduced, and the acid is not
capable of increasing to the battery nameplate rating.
6.04 The cell selection DIP switch on the control may be set incorrectly. See the Set-Up chapter of this manual
and verify that the switches are set correctly.
6.05 The battery connected to the charger may be the wrong cell size for the charger. Check the nameplate on
the battery and verify that it matches the cell size of the charger.
6.06 A bad harness/connection can cause many different problems. The best way to confirm a bad harness/
connection problem is to take measurements where the harness is connected to the charger and then
follow the wire (s) up the harness to the PC boards and measure there also. The measurement should
match what was measured at the charger connection. If it doesn’t, check the following: Check the
connectors at the square plugs where the control harness connects to the charger harness. The connec-
tors
could be pressed out of the plugs. Make sure the connectors look okay inside the edge mount connector
at the PC board (s). Make sure the harness connections are tight where they connect to the charger.
Make sure the wires are crimped to the terminals tightly and also check to make sure that they are crimped
to the bare wire and not to the insulation only.
6.07 Make sure the output connector does not have any cracks on its casing that could result in a short. Make
sure the output cable lugs are making a good connection with the battery connector. You will see traces
of pitting on the lug surface from arcing if there isn’t a good connection. This could be the result of a weak
retainer clip in the connector or lugs that were soldered on incorrectly. If the lugs had too much heat ap-
plied
to them when the cables were soldered on, the solder will wick up the cable and make it very stiff. When
they are inserted into the connector, the stiff cable forces the retainer clip down and creates poor connec-
tion
between the battery connector and the charger connector.
6.08 New batteries may not be fully formed. Contact your Battery Manufacturer’s Service Representative.
6.09 Try charging the battery on a larger amp-hour rated charger or downsize the battery to match the
available chargers size.
6.10 Do a continuity or resistance test. Check for connection points that visually appear to have been exposed
to extreme heat. Any connections that appear loose or overheated must be re-lugged and rechecked.
6.11 Check Voltage on ALL input power phases. Verify that the main power and Control Transformers are
connected per the instructions provided in the charger door.
6.12 Disconnect AC power and replace the bad AC fuse. Reapply AC power to the charger. If the fuse (s)
blows instantly, check the connections on the input side of the contactor to make sure there are no shorts
between any of the input wires. If that’s okay, then check or change the control transformer. If the fuse (s)
blow after the contactor closes, then check the input wiring from the contactor to the main transformer (s).
Refer to the charger manual and locate the diagram for your charger to confirm that the charger is wired
correctly. Also check the wires going up to the terminal block on the transformer, the wires will have
numbers that correspond to the number on the terminal block. If they are incorrect, change them and
start over. If it still blows fuse (s), the transformer will have to be replaced.

April 28, 1999 6-4

TROUBLESHOOTING
6.13 If Charger repeatedly shuts down a few seconds after initial contactor closure, perform the following for
each (1, 2, or 3) power transformer. Disconnect battery and monitor the voltage at terminals 1 to 6 of
each transformer. Reconnect battery, after 5 seconds. Line Voltage should be present from
terminals 1 to 6 of each transformer. If not, replace contactor and retest.
6.14 Use an Ohmmeter and measure directly across the DC Fuse. A good fuse will measure almost (0) Ohms
and bad one will measure a very high resistance, in the megohm range or greater. If for some reason a
DC fuse measures somewhere in between, replace the DC fuse and send it in to your local PRESTOLITE
POWER Representative.
6.15 Check for darker discolored transformer windings with charger running. Check PRI current of all
transformers. Input currents should match ±10%.
6.16 If battery electrolyte temperatures are well below 32 degrees F, the charger will not be able to adequately
charge the battery. Battery insulation or heaters would be required to keep the battery electrolyte
temperatures close to 32 degrees F.
6.17 Look at the casing of the control transformer on the input side. Reference the Charger Manual to
determine the input. There will be four pins and each one will be labeled as follows: COM (common),
208 (208VAC), 240 (240VAC), and 480 (480VAC). Some chargers are equipped with higher input voltage
control transformer labeled as follows: COM (common), 240 (240VAC), 480 (480VAC), and 575
(575VAC).
There should always be a wire on the common pin no matter what voltage is applied to the charger, and
the second wire will go to the pin labeled as the voltage that is applied to operate the charger. Measure
the
voltage on the output side of the control transformer, it should read approximately 24VAC.
6.18 Batteries that arrive at the charge with electrolyte temperatures > 115°F should not be charged until they
have been allowed to cool.
6.19 The gassing or 80% charged point may be set too low or high. Try readjusting with DIP Switch S1-7.
