The Bus voltage should gradually increase to Equalize voltage with Battery current approaching 10% of the
Battery Ah. Equalization Mode-Set Log should be stored in the event log. After the completion of the full
duration, voltage should gradually decrease to float voltage and the display will show Float mode instead of
Equalization mode.
If a system is in float mode and the Start Hour is reached, Equalize should start immediately.
If a system is not in float mode and the Start Hour is reached, then the system will wait for the float mode and
then start the Equalization.
Equalize will stop if either of these conditions is true:
•
Equalize is disabled manually.
•
Maximum temperature is reached before set duration.
Enable Equalize Mode
•
Use the keypad to go Menu>Settings>Battery Settings>VRLA Charge Profile>Equalize Mode>Status.
Enter the appropriate pin then user will be able to see settable parameters.
•
Use Web page to go Menu>Settings>Battery Settings>VRLA Charge Profile>Equalize Mode>Status.
