if you do not understand what type battery you are
using and have them set the "BATTERY TYPE"
switch accordingly.
The "BATTERY TYPE" switch is a two-position slide
switch visible in the rectangular opening on the front
of the charger. Using a small screwdriver, slide the
switch from one setting to the other through the
opening. Take care not to damage the switch when
moving it to the desired setting.
NORMAL OPERATION
Instructions printed on cover of charger are for
daily reference.
1.
Set "BATTERY TYPE" switch to the proper style
of battery to be charged.
CAUTION: MAKE SURE THE BATTERY
PACK IS A 24-VOLT, 12-CELL, SERIES
CONNECTED, 50-120 AMP-HOUR (20 HR. RATE),
RECHARGEABLE DEEP-CYCLE BATTERY
SYSTEM. THE "GEL CELL AND SEALED DEEP-
CYCLE BATTERY" SETTING CHARGES TO A
MAXIMUM ON-CHARGE VOLTAGE OF 2.38
VOLTS PER CELL. THE "REPLACEABLE
ELECTROLYTE DEEP-CYCLE BATTERY"
SETTING HAS AN ON-CHARGE VOLTAGE OF AT
LEAST 2.50 VOLTS PER CELL. VISUALLY
CHECK THAT THE BATTERY TYPE SWITCH IS
SET CORRECTLY FOR THE TYPE OF BATTERY
YOU ARE USING.
DANGER: TO PREVENT ELECTRIC SHOCK,
DO NOT TOUCH UNINSULATED PARTS OF THE
CHARGER DC OUTPUT CONNECTOR, BATTERY
CONNECTOR, OR BATTERY TERMINALS. MAKE
SURE ALL ELECTRICAL CONNECTORS ARE IN
GOOD WORKING CONDITION. DO NOT USE
CONNECTORS THAT ARE CRACKED,
CORRODED OR DO NOT MAKE ADEQUATE
ELECTRICAL CONTACT. USE OF A DAMAGED
OR DEFECTIVE CONNECTOR MAY RESULT IN A
RISK OF OVERHEATING OR ELECTRIC SHOCK.
2.
Move the power switch to "OFF" position.
3.
Connect the power supply cord to a properly
grounded, 120-volt, 60 Hertz single-phase
outlet.
4.
Connect the charger’s DC output plug to the
equipment-charging receptacle. Do not connect
the DC plug unless the power switch is in the
"OFF" position.
5.
Move the power switch to "ON" and the RED
and GREEN lights will come on steady for a few
seconds to test the lights. If the lights do not
come on, either the AC cord is not plugged in or
the AC outlet is not live. Test for a live AC outlet
by connecting a suitable appliance into the
specific outlet.
WARNING: CHARGER IS NOT TO BE USED
WHILE THE EQUIPMENT IS OPERATING.
ATTENTION: Ne pas utiliser le charger
pendant que l’equipment est en marche.
WARNING: LEAD-ACID BATTERIES
GENERATE GASES THAT CAN BE EXPLOSIVE.
TO PREVENT ARCING OR BURNING NEAR
BATTERIES, DO NOT DISCONNECT DC
CHARGING CORD FROM BATTERIES WHEN
THE CHARGER IS OPERATING. IF THE CHARGE
CYCLE MUST BE INTERRUPTED, MOVE THE
POWER SWITCH TO "OFF" AND DISCONNECT
THE CHARGER POWER SUPPLY CORD BEFORE
DISCONNECTING THE DC OUTPUT CORD FROM
THE BATTERIES. KEEP SPARKS, FLAME, AND
SMOKING MATERIALS AWAY FROM
BATTERIES.
WARNING: ALWAYS SHIELD EYES WHEN
WORKING NEAR BATTERIES. DO NOT PUT
WRENCHES OR OTHER METAL OBJECTS
ACROSS BATTERY TERMINAL OR BATTERY
TOP. ARCING OR EXPLOSION OF THE
BATTERY CAN RESULT.
Charger will output power three to five (3-5)
seconds after turning switch "ON" as indicated
by the RED light turning off, the slow blinking
GREEN light (once per second), and a slight
transformer hum.
If both lights go off about five seconds after AC
is applied, check to see if the DC plug is
correctly connected to the battery. If the DC
plug is connected properly, either an open circuit
exists in the equipment’s internal circuitry, or the
battery voltage is below 7 volts (see
Troubleshooting).
The charger has an under-voltage protection
mode, which will terminate the charge if battery
voltage does not increase above 18 volts after
10 minutes of charging. This prevents
destroying 12-volt battery systems with this 24-
volt charger. When this occurs, the RED light
will come on steady.
6.
Correct initial charge rate should be between 11
to 13 amps. As the batteries become more
charged the charge rate decreases. When the
batteries reach approximately 80% of full
charge, the GREEN light will fast blink (eight
times per second), the charge rate will have
decreased as determined by the "BATTERY
TYPE" switch setting and the condition of the
batteries.
