12B Bulk Volts DC
This is the voltage level at which the charger switches to the absorption
stage. The charger will use up to the parameter set in 12E Max Charge
Amps AC until the parameter set in 12B Bulk Volts DC is reached. The
actual battery charging voltage will be adjusted from this value when the
BTS is used.
See Table 6-4, “Battery Voltages For Setting Charging Parameters” on
page 6–21 for recommended bulk voltages.
12C Float Volts DC
This is the voltage level at which the charger will maintain the batteries
after a bulk and absorption charge. The actual battery charging voltage
will be adjusted from this value when the BTS is used.
See Table 6-4, “Battery Voltages For Setting Charging Parameters” on
page 6–21 for recommended float voltages.
12D Equalize Volts DC
This the voltage level at which the charger performs an “equalize charge”
on the batteries. The factory default setting is the same as the
12B Bulk Volts DC settings. This is to prevent accidental damage to
batteries from an unintentional equalize charge. The actual battery
charging voltage will be adjusted from this value when the BTS is used.
Guidelines for setting this menu item:
• Be sure to adjust the equalize voltage level up or down depending
upon your battery chemistry and whether or not you desire an
equalize charge on the system.
• If this feature is not desired, set this parameter to be identical to the
12B Bulk Volts DC setting.
See Table 6-4, “Battery Voltages For Setting Charging Parameters” on
page 6–21 for recommended voltages for equalize charging.
