it has been finished then the product will be converted to automatic float 

charge mode automatically and the yellow LED will be lighted on solid. 

The Equalize Duration will be paused until the condition is satisfied again 

if the voltage point is less than the value that  is lower 0.5V than  the 

equalize setpoint in half-way.   

There are two buttons on the panel, one is forced equalize charge and the 

other is forced  float  charge. It will be  converted  to  forced  equalize 

charging  mode and the green LED flashes when pressing the forced 

equalize  charging  button in float  charging  mode. The next cycle is 

automatic  equalize  charging  mode when the Equalize Duration  and 

Equalize Calendar are finished after enabling the forced equalize charging 

mode. The function is invalid  when the power supply has been in 

equalize  charging  mode.  It will be  converted  to  forced float  charging 

mode and the yellow LED flashes when pressing the forced float charging 

button in equalize charging mode. The function is invalid when the power 

supply has been in float  charging  mode. The device will keep in float 

charging mode after the forced float charging mode has been enabled. 

The  Equalize Calendar  timer which has  been started will be cleared (it 

starts once again until the Equalize Duration finished) when pressing the 

forced  equalize charging  button. The Equalize Duration  which  has  been 

started without finishing  will be paused when pressing  the forced float 

charging  button. It will not be cleared until the Equalize Calendar  has
