Charger
IMPORTANT:
Battery charger settings need to be correct for a given battery type. Always follow battery manufacturer
recommendations. Making incorrect settings, or leaving them at factory default settings, may cause the
batteries to be undercharged or overcharged.
The charge controller uses a “three-stage” battery charging cycle which utilizes multiple settings. This
menu controls the voltages and timers for the battery charger. See the charger controller
User’s Manual
for an explanation of the three-stage cycle and a description of the individual stages.
To access the Charger menu:
1. Access the Charge Controller menu as shown in Figure 90 on page 94.
2. Use the control wheel to highlight the Charger menu.
Press the button in the center of the control wheel to accept the selection.
3. Use the control wheel to increase or decrease the set points to the correct voltage.
Press the button in the center of the control wheel to accept the selection.
This should automatically move the highlighting to the next set point.
4. After setting the parameters for each set point, press the
TOP
navigation key to return to the
Main Menu screen.
