ACS Configuration Considerations

The voltage range for these alarms and cutoffs is generally set at the factory at the absolute minimum and maximum, as shown in the illustration above for 12-volt systems. Example: Lo Cutoff = 10.0V, Hi Cutoff = 16.0V, Range = 10.0 to 16.0 volts DC. The table below illustrates the factory settings and the min–max range for both 12-volt and 24-volt systems.

Charger Configuration

The ACS Charger menu displays the current status of the charger and enables you to begin an equalization charge, or to override the current charger status and force the charger into Float or Equalization mode.

Override Charger Operating Mode The charger will not begin an equalization charge until it has completed a Bulk or Absorption charge. It may be desirable to force an equalization charge in some instances. Forcing the charger into Float or Equalization mode is usually performed only during an installation, and should not be lightly considered. Consult your installer or call Xantrex Customer Service before attempting to override the charger mode. Overriding the charger operating mode is an installer-configuration item. The menu procedure is illustrated below.

Enter “Installer Mode, and then:

Equalization Request For some batteries, equalization is a regular maintenance activity; for others, equalization is damaging. Read “Section 6: Multistage Charging” (page 59) before attempting to initiate an equalization charge. Inappropriate equalization charging can ruin your batteries. An equalization request is a user-configuration item: press ENTER at the menu and follow the prompts shown below to initiate an equalization request. When you press ENTER at the YES prompt, equalization will begin immediately if the batteries are fully charged, and AC power is available. Since equalization voltage is usually above the range of the High Voltage Alarm, an audible alarm will sound briefly when it is enabled. The Faults and Charger LEDs will also flash as a visual alarm.
