4.3Mode Status (active area) and Temp Comp Indication

The CXC has four modes of operation: float (FL), equalize (EQ), boost (BST) and battery test (BT). The mode, along with temperature compensation (TC or Temp Comp) activation, is indicated in the top left “active area” of the GUI, see Figure 2. The time duration, until the mode changes, will also be shown in that active area.

Tap this active area to enter a new screen, or window of operation, for mode selection, see Figure 7 below:

4.3.1Float (FL) Mode

This is the CXC’s default mode at start up and during normal system operation. When in this mode, the rectifier’s charge (or output) voltage is driven by the float voltage setting found in the CXC’s Rectifiers menu, see 6.3.2. The icon (message) FL will display on the GUI’s upper left corner (Figure 2) when the CXC is operating in float mode.

Do not adjust the float voltage of the rectifiers when they are in Current Limit.

When operating in a mode other than float mode, tap the FL mode selection button to return to the defaultoperating mode. Tap the “check mark” button in the lower right corner of the GUI to verify the action and return to the previous screen.

4.3.2Equalize (EQ) Mode

The equalize mode is used to equalize charge a battery string. This mode can be selected via the Mode Status active area and by tapping the EQ mode selection button or by sending an external command; e.g., via web interface. When in this mode, the rectifier’s charge (or output) voltage is driven by the equalize voltage setting found in the CXC’s Rectifiers menu, see 6.3.2. The EQ icon will display when the CXC is operating in equalize mode.

A maximum time limit for equalize charging can be programmed to prevent accidental over-charge of a battery string. This limit is determined by the setting found in the EQ Timeout menu, see 6.3.2.10. Do not adjust the equalize level of the rectifiers while they are in current limit.

When operating in EQ mode, the text below the Mode Selection buttons (shown above) will display the time until FL mode in hours. Tap the “check mark” button in the lower right corner of the GUI to verify the action and return to the previous screen.

4.3.3Boost (BST) Mode

This feature (see 0) provides the supervisor with the means to equalize charge the battery at a higher voltage relative to the connected load. Activation is manual and certain conditions must be met to prevent damage to the load.

A custom alarm must be created to include all the desired factors that must be taken into account before activating BST mode. This mode will then only be permitted if the alarm is false.

Once activated, BST mode concludes with a timeout or whenever the status of the custom alarm is true and reverts to FL mode. BST mode can also be cancelled if the conditions that are required in order to activate BST mode have changed.
