Operation in Equalization Mode

battery electrolyte level. Fill only with distilled water if the electrolyte level is low. Use a battery hydrometer to measure specific gravity of each cell. For lead-acid batteries that are fully charged, the reading should be approximately 1.265 (consult your battery man- ufacturer). Equalization is needed if one or more cells have substantially lower S.G. than the others.

2.To start the equalization charging cycle, the charger must already be in operation. With the Standard Control Panel, press and hold the CHARGER ON/OFF push-button switch on the control panel for five seconds until the EQUALIZE LED comes on. With the ACS control panel, the equalize mode must be initiated through the menu system. When the charger is waiting to enter equalization mode, the EQUALIZE LED stays lit constantly. Equalization will start when the bulk and absorption charge have finished, that is, when the battery current is less than 1% of the amp-hour setting. When the system is in equalization, the CHARGE and EQUALIZE LEDs will blink.

Even if the batteries are fully charged, it will take several minutes after the charger is first turned on for it to enter equalization mode. It takes a minimum of three minutes for the charger to move through bulk and another three minutes to go through absorption before equalization begins.

3.Monitor the battery specific gravity during equalization with a battery hydrometer. When all cells have a specific gravity of approximately 1.265, manually terminate equalization. Terminate the equalization charge by momentarily depressing the CHARGE ON/OFF push-button. As a safety feature, the Prosine will time-out and exit Equalize Mode after eight hours. If the battery specific gravity is still rising and has not yet reached the target value when the charger exits equalization, restart equalization by holding the push-button for five seconds. To cancel equalization at any time, turn charger off.

4.When equalization is finished, be sure to check battery electrolyte level. Refill with distilled water only.

Adjustable Charger Mode Settings

These settings can be changed by adjusting the DIP switches on the chassis, or by using the optional Advanced Control System which gives a finer degree of control over the setpoint adjustability. For further details on these settings and instructions for changing them, refer to “Section 3: Configuration” starting on page 25.

CAUTION Incorrect settings can damage your batteries. Refer to “Section 3: Configuration”.

Temperature Compensation: Configuration DIP switches found on the side of the chassis can be set up on the Prosine inverter/charger to modify the charging characteristics depending on battery temperature. By setting the switches correctly before charging your battery, you can ensure that your batteries receive the best possible charge. The Prosine inverter/charger also has a jack for a remote battery temperature sensor which automatically adjusts the charge according to the temperature of the battery. This allows the Prosine inverter/charger to provide a more accurate temperature compensated charge.

Battery Type Selection: The DIP switch for “Battery Type” allows you to set the charge output of the Prosine inverter/charger for the charging characteristics of sealed lead acid “gel” batteries, or for the charging characteristics of conventional flooded “wet” batteries. If you can add water to your batteries, this switch should be set to the FLOODED position. If your batteries are sealed, then set this
