OUTPUT SELECTOR CONTROLS

TIMER: The main function of the timer is to prevent over charg- ing 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 rea- son 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 it’s maximum, 2.25 hours, over charg- ing will occur, but not likely cause harm to a battery that was other wise in good condition. When the charge state is not known, start out with a timer setting of 1 hour or less.

HOLD: This position defeats the timer function, allowing for con- tinuous operation. Use when you want to charge more than 2.25 hours. This is normally the case when the 2 amp charge rate is selected. Be sure to monitor the charging and stop the charge when the battery is charged.

Switch #1 - Use this switch to select the 200 Amp Engine Start and the 35 Amp Charge Rate. Switch #2 must be in the down position (Select Position) when using Switch #1.

Switch #2 - Use this switch to select the 2 Amp Charge Rate and OFF position. Also, use to select use of switch #1. Note that switch #1 is only effective when switch #2 is set to “Select Position”.

Rotary switch - Use the rotary switch (volt / rate selector, on all models except the PS-2352) to select the charge rate or engine start setting you require. Read the switch dial for those avail- able on this charger.

Model PS-3000 employs a 7-position rotary switch. You may select output voltages of 6, 12, 18 or 24 volts for charging bat- teries of those voltages or battery combinations connected in series (not parallel) in which the sum of the battery voltages adds up to the range selected. Each voltage range offers a high or low amp charge rate. The higher charge rate is more suitable for fast charging a battery to the point where it will start a ve- hicle, the lower (slower) charge rate is more suitable for fully charging (restoring) a battery.

Load Tester Switch (on PS-8050 only)

Use this switch to apply load to the battery.

Follow these easy steps:

1.Select the correct setting of the meter ( 6V or 12V ) to agree with the battery to be tested.

2.Connect the charger leads to the battery following the in- structions in section F.

3.Press the Load Switch to load on for 10 seconds and read the voltmeter.

Good (green) - indicates the battery capacity is OK. Battery may or may not be fully charged. Check the specific gravity of battery to determine the state of charge. If the specific gravity is less than full charge, check for electrical drain or possible charg- ing system trouble. Recharge battery to full level.

Yellow or Red, but needle remains steady - indicates that the battery capacity is not satisfactory. Battery may be either defec- tive or not fully charged. Check specific gravity to see which condition exists. It charging does not bring the battery specific gravity to full charge, the battery should be replaced.

Yellow or Red, but needle remains falling - indicates the bat- tery may be defective or run down. Release the load switch and note voltmeter reaction. Voltage recovery into green or above within seconds indicates a defective battery. Slow recovery indi- cates run down condition. For best results, check specific gravity.

The Ammeter indicates the amount of current measured in am- peres that is being drawn by the battery. For example, In the 50 amp charge rate a typical discharged battery will initially draw approximately 50 amps. As the battery continues to charge, cur- rent will taper to 15 to 20 amps at full charge. The Start area of the meter indicates a high rate of current being drawn from the charger. When cranking an engine, the starter motor draws up- wards to 200-300 amps. The meter needle will be at the ex- treme right side of the start area. Sometimes a battery for the first few minutes of it’s charge will draw more than 40/60 amps, in this case the needle may be within but not to the extreme right side of the start area. The 2 amp charge rate (on some models) may indicate some activity on the meter. The meter doesn’t have the resolution to display this low rate.

The Voltmeter indicates the voltage at the battery terminals. Note that Model PS-5250 is not a load tester, but a voltmeter. Use as follows:

1.Charger need not be plugged into AC outlet. Timer should be in the OFF position, 6V/12V switch in position to match battery being tested, and then connect following instruc- tions in Section F.

2.Observe the meter indication. Keep in mind that this read- ing is only a battery voltage reading, a false surface charge may mislead you. We suggest that you turn on your headlamps for a couple of minutes before you read the meter. Read a couple of minutes after you have shut the headlamps off, then follow the convenient color code of the meter.
