8.0 MAINTENANCE AND PRODUCT CARE
4. Replace a blown fuse with an identical 3AB (1/4" x 1-1/4") fast-acting 15A fuse, Littelfuse part number
0314015.MXP (or equivalent).
5. Install the battery fuse first, then the solar fuse.
8.2 Battery Replacement
Battery replacements should not be carried out in windy conditions. In all cases, the area at the
base of the post must be roped off to prevent people from being injured or killed by falling
batteries.
When the system’s battery requires replacement, it is recommended that the original manufacturer and model of
battery be used.
The general health of the battery is tracked by the system in a form of “odometer.” If battery status is reported as
Bad
(bad), this odometer function has determined the battery health is too poor to operate reliably and the
batteries should be replaced. Battery health is evaluated by considering such things as the total number of charge
and discharge cycles and the amount of time spent in a low state of charge.
The health odometer is reset by powering up the system
while the set button is pressed
using the following
procedure:
1. Remove the solar fuse and then the battery fuse and install the new battery.
2. Press and hold down EMS “set” button.
3. While continuing to hold down “set” button, reinstall the battery fuse.
4. While continuing to hold down “set” button, wait for
2ero
(zero) to appear.
5. Release the “set” button.
6. Reinstall the solar fuse.
The battery health odometer the system is now reset (i.e. it knows that new, healthy batteries have been
installed). The battery status should read
9OOd
(good) if the new batteries are 12.6V or higher, or
char
(charge) if they are between 11.7 and 12.6 volts.
