10. CONTROL PANEL
CHARGE RATE SELECTOR SWITCH
Use the charge rate selector switch to select the charge rate or engine start setting.
Charge – For charging small and large batteries. Not recommended for industrial applications.
Boost – For quickly adding energy to a severely discharged or large capacity battery prior to Engine Start.
Engine Start Provides additional amps for cranking an engine with a weak or run-down battery.
Always use in combination with a battery.
TIMER
The timer allows you to set a specied time for charging. After the timer expires, the charger stops
charging your battery. The main function of the timer is to prevent overcharging, while allowing a battery
time to obtain a satisfactory charge. To properly set the timer, you must know the size of the battery (in
ampere hours) or reserve capacity (in minutes) and the state of charge. It is important that you determine
the appropriate state of charge of your battery and set the timer accordingly.
AMMETER
The Ammeter indicates the amount of current, measured in amps, that is being drawn by the battery. As a
battery takes on a charge, it draws less current from the charger. Correspondingly, the meter will show less
current being drawn by the battery. When the current stops decreasing, the battery is charged. The start
area of the meter indicates a high rate of current being drawn from the charger. When cranking an engine,
the meter needle will be at the extreme right side of the start area. The 2 amp charge rate may indicate
some activity on the meter, although the meter does not have the resolution to display this low rate.
