Fast Charge 
After an ac supply failure, Fast Charge automatically increases the float voltage of the power 
system to recharge the batteries as quickly as possible. 
Enable Fast Charge if the site experiences frequent ac supply failures. 
  Fast Charge does NOT function during a Battery Test, Equalize or if the battery current sensor 
fails. 
  If Fast Charge is used then Battery Current Limit (BCL) should also be used. See Battery Current 
Limit on page 15 for details. 
 
 
►  To enable Fast Charge (or to stop Fast Charge manually) 
  Use the SC100 keypad to go to: Menu > Configuration > Fast Charge > Edit. 
  Or, in DCTools go to: Control Processes > Fast Charge.
