“FLOAT” (R34) and “BOOST” (R33), both located next to one of the control transformers.

4. Ad

just the FLOAT pot until the desired voltage is achieved.

Adjustment of the BOOST voltage is similar to adjustment of FLOAT, except that you adjust the BOOST

pot instead of the FLOAT pot. Be sure that the charger front panel mode switch is in BOOST whe

n you

make adjustments.

Please note that the BOOST adjustment controls the level above FLOAT voltage, not the absolute

voltage. Therefore, whenever the FLOAT the voltage is changed, the BOOST voltage also changes.

Factory-Set Output and Alarm Voltages

NOTE:

Output voltages are temperature compensated (vary with temperature). The factory settings

below are at 20 degrees C. The compensation is

-0.18% per degree C. The alarm voltage settings are

NOT temperature compensated.

Chart 4.2 shows relationships between charger output voltage, alarms and high volt shutdown. Output

voltage is temperature compensated down to ten degrees C; compensation then ends.

To determine the charger’s voltage at temperatures other than

20 deg. C., multiply number of degrees C

difference between ambient and twenty C times .0018. Multiply that product times the factory voltage

setting (e.g. 27.24) and add it to the factory setting. Examples:

Example 1:

Float voltage at 10 degrees C of a 24 volt charger set for 27.24 volts at 20 degrees C:

20-10 (.0018) (27.24) + 27.24 = 27.73 volts

Example 2

: Float voltage at 50 degrees C of a 24 volt charger set for 27.24 volts at 20 degrees C:

20-50 (.0018) (27.24) + 27.24 = 25.77 volts
