Battery Charger; Operating Instructions - JLG E450A Service And Maintenance Manual

3.8 BATTERY CHARGER

JLG MACHINES EQUIPPED WITH DELTA Q BATTERY CHARGERS ARE DESIGNED
FOR THE BEST PERFORMANCE WITH OEM FACTORY APPROVED BATTERIES.
APPROVED JLG REPLACEMENT BATTERIES ARE AVAILABLE THROUGH JLG'S
AFTERMARKET PARTS DISTRIBUTION CENTERS OR JLG'S AFTERMARKET PRO-
GRAMS. FOR ASSISTANCE WITH PROPER BATTERY REPLACEMENT, PLEASE
CONTACT YOUR LOCAL JLG SUPPORT OFFICE.
BATTERIES APPROVED BY JLG HAVE BEEN TESTED FOR COMPATIBILITY WITH
THE ALGORITHM PROGRAMMING OF THE DELTA Q BATTERY CHARGER TO
OPTIMIZE BATTERY LIFE AND MACHINE C YCLE TIMES. THE USE OF NON
APPROVED BATTERIES IN YOUR JLG EQUIPMENT MAY RESULT IN PERFOR-
MANCE ISSUES OR BATTERY CHARGER FAULT CODES. JLG ASSUMES NO
RESPONSIBILITY FOR SERVICE OR PERFORMANCE ISSUES ARISING FROM THE
USE OF NON APPROVED BATTERIES.
LEAD ACID BATTERIES MAY GENERATE EXPLOSIVE HYDROGEN GAS DURING
NORMAL OPERATION. KEEP SPARKS, FLAMES, AND SMOKING MATERIALS
AWAY FROM BATTERIES. PROVIDE ADEQUATE VENTILATION DURING CHARG-
ING. NEVER CHARGE A FROZEN BATTERY. STUDY ALL BATTERY MANUFACTUR-
ERS' SPECIFIC PRECAUTIONS SUCH AS RECOMMENDED RATES OF CHARGE AND
REMOVING OR NOT REMOVING CELL CAPS WHILE CHARGING.
RISK OF ELECTRIC SHOCK. CONNECT CHARGER POWER CORD TO AN OUTLET
THAT HAS BEEN PROPERLY INSTALLED AND GROUNDED IN ACCORDANCE
WITH ALL LOCAL CODES AND ORDINANCES. A GROUNDED OUTLET IS
REQUIRED TO REDUCE RISK OF ELECTRIC SHOCK - DO NOT USE GROUND
ADAPTERS OR MODIFY PLUG. DO NOT TOUCH UNINSULATED PORTION OF OUT-
PUT CONNECTOR OR UNINSULATED BATTERY TERMINAL. DISCONNECT THE AC
SUPPLY BEFORE MAKING OR BREAKING THE CONNECTIONS TO THE BATTERY
WHILE CHARGING. DO NOT OPEN OR DISASSEMBLE CHARGER. DO NOT OPER-
ATE CHARGER IF THE AC SUPPLY CORD IS DAMAGED OR IF THE CHARGER HAS
RECEIVED A SHARP BLOW, BEEN DROPPED, OR OTHERWISE DAMAGED IN ANY
WAY - REFER ALL REPAIR WORK TO QUALIFIED PERSONNEL. NOT FOR USE BY
CHILDREN.

SECTION 3 - CHASSIS & TURNTABLE

Operating Instructions

ALWAYS USE A GROUNDED OUTLET. WHEN USING AN EXTENSION CORD,
AVOID EXCESSIVE VOLTAGE DROPS BY USING A GROUNDED 3-WIRE 12 AWG
CORD.
1. The charger will automatically turn on and go through a
short self-test. All LED's will flash in an up-down
sequence for two seconds. The yellow "Charging" LED
will turn on and a trickle current will be applied until a
minimum voltage is reached.
2. Once a minimum battery voltage of 2 volts per cell is
detected, the charger will enter the constant-current
charging stage and the yellow LED will remain on. The
length of charge time will vary by input voltage and
ambient temperature.
3. When the green "Charged" LED turns on, the batteries
are completely charged. The charger may now be
unplugged from AC power. If left plugged in, the char-
ger will automatically restart a complete charge cycle if
battery voltage drops below a minimum voltage or 30
days have elapsed.
4. If a fault occurred during charging, the red "Fault" LED
will flash with a code corresponding to the error.
