Output Voltage Adjustments 

The output voltage of the A36D charger is set to a default value, but should be adjusted to meet the battery 
manufacturer  recommendations.  To  adjust  the  Float  and  Equalize  output  voltage,  refer  to  Section  3.4.1.1. 
Adjustments are recommended to be made with no connections on the DC output terminals of the charger, but 
can  also  be  done  with  the  battery  connected.  Output  adjustments  can  be  carefully  made  with  the  charger 
energized until the desired voltage is achieved. 

NOTES:

  

1.

 

When making output voltage adjustments with batteries connected, the immediate change will be reflected 
on  the  output  current  and  NOT  the  voltage  due  to  the  voltage  difference  between  the  output  and  the 
batteries. 

2.

 

In parallel systems, each charger MUST be isolated to properly perform output voltage adjustments.  

Raising Output Voltage with Batteries Connected 

Note the DC load prior to making adjustments. Increase the Float/Equalize output voltage setting via Settings 
Menu as shown on  Section 3.4.1.1. The output  current will rise and gradually drop to its steady load current. 
Meanwhile, the output voltage will slowly rise to its setpoint. Once steady, repeat incrementing the output voltage 
setting until the desired setpoint is reached. 

Lowering Output Voltage with Batteries Connected  

Note the DC load prior to making adjustments. Decrease the Float/Equalize output voltage setting via Settings 
Menu as shown on  Section 3.4.1.1. The output  current will drop and gradually  rise to its steady load current. 
Meanwhile,  the  output  voltage  will  slowly  lower  to  its  setpoint.  Once  steady,  repeat  decrementing  the  output 
voltage setting until the desired setpoint is reached. 

NOTE:

  Immediate  change  in  voltage  might  not  be  seen  due  to  the  backfeed  of  the  battery  voltage  when 

performing adjustments.
