Advanced Charger Setup
1. Press the Menu button.
2. Press the left or right arrow buttons to scroll to the Fan Speed window
3. Press the Select button.
4. Press the up or down arrow buttons to select the desired speed.
a. High: The fan will spin up to its maximum speed. This is the recommended setting for optimal performance.
b. Low: The fan will spin up to a designated speed (below max). If there is a significant load on the charger, it may limit its maximum output current in
order to maintain a safe internal temperature.
c. Off: Forces the Fan to stay off. If there is significant load on the charger, it may limit its maximum output current to maintain a safe internal temperature.
6. Press the left or right arrow buttons to scroll to the Max Output window.
7. Press the Select button.
8. Press the up or down arrow buttons to select the desired maximum output amperage. Low output may be selected to reduce load on the AC source.
AC current is approximately one tenth of the DC current at 120V line voltage and one twentieth of the DC current at 240V line voltage.
9. Press the OK button once desired max amperage output is reached.
10. Press the left or right arrow buttons to scroll to the Display window.
11. Press the Select button.
NOTE: The designated maximum amperage is the total available amperage to be supplied among all 3 outputs. Selecting an amperage less than the maximum
could result in under charging of batteries.
5. Press the OK button once desired speed is reached.
NOTE: Selecting High or Low will not necessarily turn the fan immediately on or increase the fan speed. In either of these settings the charger will only alter the fan
speed if the internal temperature rises enough to warrant fan circulation. The fan Low setting is for quiet mode.
