LED Status Indicator

For example, if the system battery voltage is 24 volts and the internal Bulk voltage setting is set for 28 volts, you can estimate how much below the Bulk setting the batteries are by subtracting the number in Table 3-1(the internal Bulk setting).

With the LED indicating three blinks, the battery voltage is approximately 27 volts (28 volts Bulk setting minus

1.00 volts in the table).

With the LED indicating one blink, the battery voltage is somewhere below 26.5 volts (28 volts Bulk setting minus >1.50 volts in the table).

Important: LED will light green only in Diversion and Charge Control mode (unless it is reinstalled backwards).

Blinking Green

The controller is in the Charge Control or Diversion Control mode and the battery is not fully charged. As the battery voltage approaches the BULK setting, the status LED will blink green several times (up to five) and then pause, indicating the battery voltage is approaching the bulk setting and provides an indication of the battery condition. Refer to Table 3-1to determine the battery voltage.

Important: A single green flash indicates the battery is well below the bulk voltage setting. It does NOT indicate the batteries are charging or their state-of-charge.

Solid Green

The battery is being charged in the FLOAT stage. The status LED remains ON solid unless the batteries drop below the float voltage setting for an accumulative period of one hour. This allows the user to confirm that the system reached the float stage during the charging process when checked at the end of the day. Reaching the float stage frequently is a good indication of proper system operation and will maximize battery life and performance.
