Connection
Conguration Mode
1.  Connect the charger to the batteries as indicated 
under Installation.
2.  Check the POL LED on the front panel. If it is glow-
ing red, the battery is connected in reverse polarity. 
Correct the connection to the battery (The red terminal 
should go to Positive and black to Negative).
3.  Once the POL LED is off, connect the charger to the 
Input power source. The I/P LED should start glow-
ing green. This indicates that the charger is receiving 
power from the DC source and that its internal power 
supply is working. 
1.  Press and hold the Program (PRG) button for three seconds until you hear a beep and the 
DEV LED starts blinking. This indicates that the unit is in Conguration mode. 
2.  Press the Program (PRG) button to cycle through the parameters you can program. The pa-
rameter which you programming can be determined by which bottom row LED is blinking.
If the DEV LED is 
blinking, you are 
programming 
the Battery Type 
parameters.
If the FLT LED is 
blinking, you are  
programming the 
Default Battery  
Temperature  
parameters.
If the BAT LED is blinking, you are 
programming the Current Limit 
parameters.
3.  Press the Select (SEL) button to cycle through the settings for each parameter. The setting 
can be determined by the combination of top row LEDs glowing. 
After turning the charger on, it will immediately begin charging any connected batteries with 
its pre-programmed parameters. These parameters can be accessed and changed through 
Conguration mode.
