LED Status Indicator
975-0004-01-02 Rev D 57
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).
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 3-1 to determine the battery voltage.
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.
Important: LED will light green only in Diversion and Charge
Control mode (unless it is reinstalled backwards).
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.
