10. OPERATING INSTRUCTIONS
10.1 SELECT CHARGE RATE
The CHARGE RATE SELECTOR allows you to select the correct amp
draw rate to match your charging needs. Read the following operating
instructions for making the proper settings for charging a battery.
When you first start charging a battery, the amp reading will be high. As
the battery becomes charged, the reading will decrease.
To determine the amount of amps being drawn by the battery:
a. Press the Select Display Mode button until the AMPS LED lights.
b. When the 55A setting is used, the charger switches between 55A boost
mode and 10A mode. You should use a lower charge setting if the volt-
age reading is "OL" or is reading higher than 14.2 Volts for more than 3
minutes and you are not in automatic mode.
c. When charging at 20 amps, the display should show 20 amps for
a discharged battery and 7-8 amps for a fully charged battery. You
should stop charging the battery at this time if you are using the
manual mode.
d. At the 2 amp charge rate, little or no display change will occur.
10.2 TIMER
The timer is designed to allow the battery to be charged for a designated
amount of time. To accurately charge your battery, you must know the size
of the battery in ampere hours or reserve capacity in units, as well as the
state of charge. Since this information is not known by the charger, the
timer limit is set at 2.25 hours to prevent the battery from overcharging to
a point where it can be severely damaged. If you do not know the charge
state of your battery, set the timer at one hour or less, or use the auto-
matic setting.
