Safety: General
• Do not operate a charger that is not working correctly. An electric shock
hazard or battery explosion hazard from overcharging may exist.
• Do not attempt to service the charger yourself unless you are a trained
service technician. The warranty is void if the charger case has been
opened. Always follow installation instructions closely. The high voltages
inside the charger are a shock hazard and can cause serious injury or
death.
• Though the charger is resistant to water and spray washing do not fully
immerse or spray wash for an extended (more the 5 seconds in one
position) time. Liquid can get inside charger and may cause serious injury
or death.
• The charger is designed for use in industrial areas. It is not designed to be
used in medical (hospital) environments where interference with life critical
equipment could cause death or serious injury.
• There could be a spark during charging. Be careful when using fuels,
solvents or other flammables near the charger or batteries. An explosion
could result causing death or serious injury.
• The charger surface can get hot while operating and contact with the skin
or surrounding materials should be avoided.
Safety: Power
• To reduce the risk of an electric shock, connect only to a properly grounded
single-phase (3wire) outlet.
• Ensure that the AC voltage supplied to the charger is within the ranges in
the specification table. Voltages outside this range, particularly high
voltages, can result in an electric shock and fire hazard.
• If you use an extension power cable with your charger, ensure the total
current draw of the items plugged into the extension power cable do no

exceed the current rating of the extension cable and meet all national and
local electrical code requirements. See Specifications page for current
draw of charger. Overloaded extension cords can catch fire and cause
property damage, serious injury or death.
• Do not operate charger if wiring is damaged including cut insulation or
pinched wires. An electric shock could cause serious injury, or death.
• The charger includes an interlock relay to prevent the machine from
operating while charging. Please see the machine manufacturer’s
documentation for correct wiring and test to ensure correct operation.
Safety: Batteries
• See battery suppliers guide for proper care of batteries and follow
directions carefully. Failure to follow battery care instructions can result in
battery explosion and property damage, severe injury, or death during
charging.
• When attaching charger leads to battery terminals be careful that tools do
not short between battery terminals. Shorting between battery terminals
may cause extreme arcing resulting in explosion or extreme heat that can
cause burns.
• Do not disconnect charger terminals while batteries are charging. Sparking
can occur which could ignite flammable battery gases and cause an
explosion. Always turn the charger off first (unplug from AC).
• Do not touch battery terminals or any exposed electrical parts. Contact
with battery terminals or other exposed electrical parts may cause an
electric shock. Remove all watches, rings, and jewelry to avoid arcing and
electric shock.

Operation
1) Determine whether flooded or GEL (sealed) type batteries are being charged. The
charge profile is set by a yellow wire loop at the back of the charger. If the yellow wire is
a loop (connected) at the time of the charger start up (plugged into AC voltage), then
the charging will be for a flooded battery. If the yellow wire loop has been cut (opened)
before charger start up then charging will be for a GEL type battery. The selected
profile is valid until AC power is turned off
2) Plug the charger into a single phase AC socket with a nominal voltage rating of 100V,
110V, 115V, 120V, 220V, 230V, or 240V and a frequency rating of 50 or 60Hz. The
charger automatically senses and adjusts to the AC voltage and frequency
3) The charger will flash the three green LEDs in a start-up check then start charging the
batteries. If the charger has been set to “GEL” in step 1) the “GEL”LED is lit.
4) The three green LED’s indicate the charging progress. When the battery is 0 to 50%
charged the 50% LED flashes. When the battery is between 50 to 75% charged the
50% LED is on while the 75% LED flashes. When the battery is between 75 to 100%
charged the 75% LED is on and the 100% LED flashes. When the battery is fully
WARNING: There could be a spark during charging. Be careful when using
fuels, solvents or other flammables near the charger or batteries. An explosion may
result causing serious injury or death.

WARNING: To reduce the risk of an electric shock, connect only to a properly
grounded single phase (3wire) outlet. Electric shock hazard may cause serious
injury or death.

CAUTION: To reduce the risk of fire, use this charger only on AC circuits and
extension cords capable of handling the AC Input currents (Max. Amps) defined in
the electrical specifications. Use must be in accordance with all National and Local
Electrical Codes for the location of use. Overloaded cords or circuits present a fire
and shock hazard and may result in property damage, serious injury, or death.

CAUTION: The charger surface may get hot while charging. Avoid skin
contact with the charger surface. Keep surrounding materials away from charger
surface to avoid heat damage and to allow cooling.

charged the 50%, 75% and 100% LEDs are on. Charging time is dependent on depth
of battery discharge, battery condition, and temperature.
5) If the charger is left plugged in after charging is complete (all LEDs on) the charger goes
into maintenance mode to keep batteries charged while in storage. The charger
continuously measures battery voltage and restarts the charging cycle if the battery
voltage drops below about 25V. This keeps batteries charged while in storage but does
not boil-out the electrolyte over time.
6) Turn-off charger by unplugging (disconnect from AC voltage).

Technical Operation Summary – The charger is an advanced, microprocessor controlled, high
frequency switching type charger. From 0% to 75% a constant current is provided to the
battery (bulk charging) until a pre-set battery voltage is reached. From 75% to 100% a
constant voltage is maintained and the charging current decreases (absorption charging).
When the charging current falls below 2 to 3A charging is complete. The charging curve is
temperature compensated using the starting temperature of the charger as the battery
temperature.
The charger will work even with batteries in a severe discharge state with terminal voltages as
low as 1V and there is no need to ‘boost charge” weak batteries before charging. The charger

has an 18 hour timer in case charging can not be completed due to battery problems – see
troubleshooting section. The charger senses and flashes error codes for problems – see
troubleshooting section.

Maintenance
1) All electrical connections must be kept clean and tight. Sometimes connections can
look good outside but be corroded inside causing an output connection error (one flash
failure, see troubleshooting).
2) The charger cools through the case fins. If the fins become covered with debris the
charger’s over-temperature protection system may reduce charging power. Clean-off
fins to improve cooling.
3) Replace the charger if case damage breaks the water-tight seal.
4) Inspect wiring weekly, including AC plug, AC cord, DC wires to battery, and interlock
wires for cut insulation, pinching, or other damage. Repair to avoid electric shock.
AC Ground – green with yellow stripe
AC Neutral – light blue
AC Line (Hot) – brown
DC Battery Negative (-) – black
DC Battery Positive (+) – red
Interlock wires – black and white
5) Follow battery supplier recommendations for battery care and maintenance.
Note – most battery charging problems relate to battery care and not charger
problems.
WARNING: Disconnect from AC voltage before doing any service. When
plugged-in the AC wiring is an electric shock hazard. Disconnecting the DC output
wires near the batteries when the charger is ON may cause the batteries to explode
resulting in serious injury or death.

WARNING: Risk of an electric shock causing serious injury or death. Do not
touch un-insulated parts of the charger wires, battery connector or battery terminals.
Be careful with tools as shock or arcing from shorting of electrical parts may cause
serious injury or death. Remove rings, watches, and jewelry to avoid arcing and
electric shock.

Troubleshooting
Identify the problem from the following list and refer to the appropriate section for detailed
instructions.
1. CHARGER DOES NOT TURN ON.
2. 3 LED’s BLINK SIMULTANEOUSLY
3. 100% LED BLINKS WHILE 50% AND 75% LED'S ARE "OFF"
4. BATTERIES DO NOT FULLY CHARGE
5. THE AC SUPPLY CIRCUIT BREAKER OR FUSE IS BLOWN
1. CHARGER DOES NOT TURN ON.
Double check the outlet to ensure it is working by trying out another known good piece of
equipment on the outlet. Check the AC plug and wire to ensure both are in good condition.
Replace charger if everything else is correct.
2. 3 LEDS BLINK SIMULTANEOUSLY
The faults identified below cause the 3 LED’s to blink simultaneously and a buzzer to sound. If
the cause of the fault is removed the charger restarts automatically, the LEDs go into normal
operational mode, and the buzzer stops.
▶
3 LEDS BLINK ONCE SIMULTANEOUSLY : OUTPUT CONNECTION ERROR.
-> CHECK THE BATTERY AND CHARGER CONNECTION AND CORRECT
(The output may not be connected to the batteries or the connections to the batteries may
have corroded or loosened. The output may be shorted due to improper connection to the
batteries or pinched wires. The output may be connected in reverse polarity to the batteries.
The charger is not damaged by any of these problems.)
WARNING: Do not disassemble the charger. High voltages inside the charger
are an electric shock hazard and may result in serious injury or death.

WARNING: Do not operate the charger if it is malfunctioning. Personal injury
or property damage could result. Electric shock hazard may cause serious injury
or death.

CAUTION: If the AC plug or receptacle is broken, twisted, bent or loose, it cannot
make a good electrical connection and an electric shock hazard may exist. Have it
repaired or replaced by a qualified person immediately. DO NOT USE THE CHARGER
UNDER THIS CONDITION. Fire, injury, or death may result if not corrected.


▶
3 LEDS BLINK TWICE SIMULTANEOUSLY : AC VOLTAGE PROBLEM.
-> CHECK THE AC INPUT VOLTAGE. THE CHARGER IS INDICATING
THE AC VOLTAGE IS TOO LOW OR TOO HIGH. CORRECT.
(See the electrical specification table for the allowable AC voltage input ranges. This is an
unusual problem and would most likely occur with a very poorly regulated engine-generator
set providing the AC voltage to the charger)
▶
3 LEDS BLINK THREE TIMES SIMULTANEOUSLY : CHARGER IS OVERHEATED.
-> NO ACTION REQUIRED. WHEN THE CHARGER COOLS, CHARGING WILL
RE-START AUTOMATICALLY. CHECK AND CORRECT FOR DIRT OR OTHER DEBRIS
ON CHARGER THAT MAY BE REDUCING COOLING.
▶
3 LEDS BLINK FOUR TIMES SIMULTANEOUSLY : OUTPUT OVER CURRENT.
-> NO ACTION REQUIRED, CHARGER WILL CORRECT AND RE-START
AUTOMATICALLY.
3. 100% LED BLINKS WHILE 50% AND 75% LED'S ARE "OFF"
The 18 hour timer has elapsed or a bad cell in the battery has been detected. Causes:
-> BATTERIES ARE EXTREMELY DISCHARGED. UNPLUG AND THEN PLUG-IN
CHARGER TO RE-START CHARGE CYCLE TO COMPLETE CHARGING.
-> BATTERIES ARE WEAK, OLD, OR HAVE ONE OR MORE BAD CELLS. BATTERIES
WILL STILL CHARGE BUT CAPACITY WILL BE REDUCED. REPLACE BATTERIES.
4. BATTERIES DO NOT FULLY CHARGE
- If the batteries are charged overnight, make sure the AC supply is not being switched-off at
night with other building items.
- If batteries are new they sometimes need 20 to 30 charge/discharge cycles before they
charge normally. With new batteries the charger LEDs may only show 50% on, 75% on, and
100% flashing after overnight charging. The batteries and charger are fine – the machine
should be used and charged overnight. Within a few weeks all three LEDs will go steady on at
the end of charge.
- If batteries are old check the battery condition following the battery supplier’s instructions.
Check for dead cells or reduced capacity. Replace charger only if other problems are not
found. If the charger LEDs are showing charging progress and charger case gets warm after
several hours the charger is probably good and the batteries bad.
- If the 50% and 75% LEDs are “off” and the 100% LED is blinking after a long charge time, the
batteries have not fully charged after 18 hours of charging time. If this occurs with new
batteries the machine should be used normally and the problem should go away after several
weeks of use. If the batteries are old they may be bad and should be checked.
5. THE AC LINE CIRCUIT BREAKER OR FUSE IS BLOWN
An overloaded AC circuit, defective circuit breaker, defective fuse, or a charger problem can
cause this condition. First, check the total load on the AC circuit to avoid overload. If total AC
load is OK connect the charger to a different AC outlet (on a different circuit) in the building. If

HB600-24B CHARGER MANUAL 06JAN2009

the charger operates properly on other AC outlets, a qualified person should correct the AC
circuit problem. If the AC supply checks good, the charger should be replaced.
Note: Over 1/2 of all battery chargers returned as "failed" are good. Please follow the
troubleshooting procedures carefully and check all other items before returning the
charger as failed.
Replacing the Charger
Replace only with charger designed for use with the batteries and machine to ensure
compatibility with all machine systems. Make sure the charger is unplugged before replacing
and be careful tools do not short battery connections which can cause electric sparks. Ensure
connections are the same as the original charger with wires connected by a qualified person
(see tag on AC cord):
AC Ground – green with yellow stripe
AC Neutral – light blue
AC Line (Hot) – brown
DC Battery Negative (-) – black
DC Battery Positive (+) – red
Interlock wires - White and black
Make sure all connections are clean and tight to provide a good electrical connection. Check
all machine operating systems after replacement to ensure proper operation (see manual).
WARNING: Disconnect from AC voltage before doing any service. When
plugged-in the AC wiring is an electric shock hazard. Disconnecting the DC output
wires near the batteries when the charger is ON may cause arcing and the batteries
to explode resulting in serious injury or death.

WARNING: Risk of an electric shock causing serious injury or death. Do not
touch un-insulated parts of the charger wires, battery connector or battery terminals.
Be careful with tools as shock or arcing from shorting of electrical parts can cause
serious injury or death. Remove rings, watches, and jewelry to avoid arcing and
electric shock.

WARNING: Do not disassemble the charger. Take it to a factory-authorized
service agent when service or repair is required. High voltages inside the charger
are an electric shock hazard and can result in serious injury or death.
