characterization was not saved because of a
change in the bus voltage (possibly caused by a
load disconnect).
Canceled: Data from the last characterization
was not saved because the characterization was
stopped manually.
Characterization Data Management
Battery characterization data can be saved to file for later use. This is useful if several sites use
batteries of the same type and size. However, characterization of each battery will provide the most
accurate estimate of Time Remaining.
► To save characterization data to a file
1 In Web go to Batteries > Battery Time Remaining.
2 When the battery characterization is completed, click on Characterization Data: Download.
3 Click Save. Type a file name (*.dcf) and browse to the required location. Click Save.
DCTools cannot save the characterization data.
► To load battery characterization data into the SC300
Use Web to restore the *.dcf (configuration fragment) file previously saved. Refer to Backup and
Restore on page 23.
Reset Ah Discharged
The SC300 monitors battery discharge and maintains a value called Ah Discharged. In a new SC300
Ah Discharged is set to zero. During operation of the dc power system the value is increased as the
battery is discharged, and reduced as the battery is recharged.
The value of Ah Discharged is used to start the Fast Charge control process. See details on page 32.
► To view current value of Ah Discharged
• Use the SC300 keypad to go to: Battery > Battery > Ah Discharged
• On the web, the Ah Discharged value is shown next to the battery icon.
• Or go to: Batteries.
If a battery or the SC300 is changed, then reset the value of Ah Discharged to zero (when the battery
is fully charged).
► To set the value of Ah Discharged back to zero
• Use the SC300 keypad to go to: Battery > Reset State > Enter > Reset.
• Or, on the web or DCTools, go to: Batteries. Click Reset Ah Discharged.
Any active or pending Fast Charge or Equalize will be cancelled.
