H. OUTPUT SELECTOR CONTROLS

TIMER: 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 auto-

motive 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 charging

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 continuous

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

40 amp charge rate. Switch #2 must be in the down position (40amp /

200 amp select) when using switch #1.

Switch #2 Use this switch to select the 2 amp charge rate. Also use to

select use of switch #1.

Rotary switch - Use the rotary switch (volt / rate selector, on all mod-

els except the SE 2001) to select the charge rate or engine start setting

you require. Read the switch dial for those available on this charger.

Load Tester Switch (on SE 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 instructions

in section F.

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

meter.

Good (green)

- indicates the battery capacity is OK. Battery may or

may not be fully charged. Check the specific gravity of battery to deter-

mine the state of charge. If the specific gravity is less than full charge,

check for electrical drain or possible charging system trouble. Recharge

battery to full level.

Yellow or Red, but needle remains steady

- indicates that the bat-

tery capacity is not satisfactory. Battery may be either defective 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 battery

may be defective or run down. Release the load switch and note volt-

meter reaction. Voltage recovery into green or above within seconds

indicates a defective battery. Slow recovery indicates run down condi-

tion. For best results, check specific gravity.

The Ammeter indicates the amount of current measured in amperes

that is being drawn by the battery. For example, In the 40 amp charge

rate a typical discharged battery will initially draw approximately 40 amps.

As the battery continues to charge, current will taper to 15 to 20 amps

at full charge. The Start area of the meter indicates a high rate of cur-

rent being drawn from the charger. When cranking an engine, the starter

motor draws upwards to 200-300 amps. The meter needle will be at the

extreme 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 SE 4022 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 instructions in Section F.

2. Observe the meter indication. Keep in mind that this reading 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 min-

utes 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.
