Top Off Settings - Default setting: Off
Charge profile with the Top Off settings enabled looks similar to the Equalize end of charge mode (End of charge option 2). The difference is that in the Top Off mode the following parameters can be adjusted:
-Top Off Time, ranging from 0 to 5 hours;
-Top Off Voltage, ranging from 28 to 32.4 Volts;
-Top Off Current, ranging from 0.5 to 4.5 Amperes.
The Top Off mode is enabled by setting the Top Off Time to a value higher than zero. The charger enters the Top Off mode at the end of the main charge cycle (after the constant voltage part) and sets the output current to the value defined by the Top Off Current setting. The
(1)preset Top Off Time expires or (2) battery voltage reaches the Top Off Voltage setting, whichever happens first.
At the end of the Top Off mode, the charger continues according to the End of Charge Mode settings - stands by and awaits for the restart voltage or contin- ues the float mode.
To program the charger:
Curtis chargers do not use the 1311's Monitor, Faults, or Functions Menus. The Information and Programmer Setup Menus operate as describe in the 1311's instruction manual with the exception of the Serial Number submenu in the Information Menu – this field is filled with a default value of 12345678.
4.2.1.Disconnect the charger from the AC outlet and battery.
4.2.2.Attach the programmer to the
4.2.3.Apply AC power to the charger. The yellow and green light indicators will alternately blink, indicating that the charger is in programming mode.
4.2.4.Configure the programmable parameters described above.
4.2.5.Once the programmable parameters have been defined, disconnect the 1311 programmer from the charger and follow the charger installation instructions.
