24-VOLT/30-AMP OUTPUT BATTERY CHARGER WITH SWITCHABLE 120/240 VAC INPUT SELECTOR.
1.
This micro-processor-controlled charger utilizes full-wave recti
fi
cation.
2.
Safety functions include:
a.
It will not turn on unless voltage is present at the charge lead (minimum 2 volts).
b.
It will not turn on if lead polarity is reversed.
3.
The Master Charger is fully automatic and utilizes “average” and “
fl
oat” functions to sense the state of charge of
the battery to guard against over-charge.
4.
Protect Setting
c.
The transformer uses a temperature fuse to protect the unit against overheating.
d.
The DC output also has a fuse.
e.
USAGE:
1.
Before plugging the unit into the main power source, connect the SB connector to the battery charge lead.
2.
Insert the main power input cable into the power source socket.
3.
When the charger starts, there is a delay of about 5 seconds as the unit senses the battery connection.
4.
Using equalizing charge method:
a.
After the initial charge circuit is established, press “EQU/DAI”. This feature will attempt to equalize the charge
between batteries. (See equalizing batteries, page 5-151)
5.
Make sure that battery
fl
uid levels are checked on a regular basis and topped o
ff
in accordance with battery
manufacturers recommendations.

fi
ll kit, page 2-67)
FRONT PANEL INDICATORS
1.
AC power indicator continuously on means the unit is connected and ready for use.
2.
AC power indicator
fl
ickering means the positive and negative cables are reversed (reverse polarity), the lead is not
connected, the DC output fuse is burned out, or the battery voltage is under 2 volts.
3.
EQUAL light
fl
ickering means the unit is in the process of equal charging.
4.
DAILY light
fl
ickering means the unit is in the process of generally charging.
5.
80% CHARGE light
fl
ickering means charging has reached 80% capacity.
6.
FULL CHARGE indicator light:
b.
Constantly lit means the charge is complete.
c.
Flickering means charging has failed, possibly because of a bad battery. Consult the battery manufacturer’s
guidelines for battery testing.
NOTICE:
Before connecting the battery, con
fi
rm the output voltage of the charger is the same as that of the battery.
*Before inserting the power AC plug, con
fi
rm that the voltage to be required of the charger is the same as that of the local
power supply.
*Cut o
ff
the main power source before removing the battery to prevent the danger of a gas explosion.
*Do not operate the accessories of the battery during charging.
