11.operating instructions
11.1TIMER
The main function of the timer is to prevent over charging 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. Often the state of charge is not known, this is one reason why the timer was limited to 2.25 hours. With the aid of a battery load tester the state of charge can be obtained within a few seconds. For example, the average size automotive battery at a 50% state of charge will require 1 to 1.5 hours of charging at the 40 amp rate to reach the full charge state. For the same battery with the timer set to its maximum, 2.25 hours, over charging will occur, but not likely cause harm to a battery that was otherwise in good condition. When the charge state is not known, start out with a timer setting of one hour or less, or use the automatic setting.
11.2HOLD
This position defeats the timer function, allowing for continuous operation.
AUTOMATIC MODES: Put the timer in the HOLD position when the bat- tery charger is in one of the automatic modes, otherwise the timer will shut the charger off when the set time expires regardless of whether the charge is complete or not. The green “charged” LED will light and the fan will shut off when the charging is complete.
MANUAL MODES: Use when you want to charge more than 2.25 hours.
Be sure to monitor the charging procedure and stop it when the battery is charged. Not doing so may cause damage to your battery.
11.3AMP RATE SELECTOR SWITCH
Use the amp selector switch to select the charge rate or engine starting setting you require.
