Manual Start – Zero Volt Battery Start 

The “Manual Start” menu allows the user to start the charger when the battery voltage is lower than the minimum

does not recognize, and (2) when the battery can tolerate the minimum output voltage setting of the charger. 
See the output voltage setting information below: 

 

The 30V model has a minimum output voltage setting of 2V.  

 

The 60V model has a minimum output voltage setting of 6V.  

 

The 90V model has a minimum output voltage setting of 8V.  

 

The 150V model has a minimum output voltage setting of 12V. 

After selecting this menu, press the “ENTER” button. To start the charger, select YES & press the “ENTER” 
button again. The charger will start charging the battery with the minimum output voltage setting & 10% 

current limit.
