[. . . ] Battery must be disconnected to clear and reset (see section 4. 2-6) · High Temperature: At very high temperatures, PV array first disconnected, then the load. · Emergency: If battery is disconnected, the PV and load are instantly disconnected for safety and to protect the load. Battery charging, equalization, and high voltage functions are corrected for ambient temperature variations. Battery charging is automatically boosted based on low state-of-charge or elapsed time. Temperature Compensation Equalization NOTE: Actual charging setpoints of the ProStar controller are adjusted for temperature, equalizations, and battery type. In addition, many delays are built into the controller. Remember to consider these factors when working with the controller. 5. 3 INSPECTION AND MAINTENANCE At least 2 times per year the following inspections and maintenance are recommended for best controller performance. 1. Confirm that the desired BATTERY TYPE has been selected (check green LED). Confirm that the current levels of the PV array and load do not exceed the ProStar ratings. Inspect for loose, broken, or burnt wire connections. Be certain no loose stands of wire are touching other terminals. Check that the controller is securely mounted in a clean, protected environment. Be certain the ventilation holes are not blocked. 11 6. Inspect for dirt, insects, nests, and corrosion. Check that the controller functions and LED indicators are correct for the system conditions at that time. 5. 4 TROUBLESHOOTING If something seems wrong with the PV system (for example, the load is not working or the battery is not charging), then it may be necessary to troubleshoot the controller. Some basic troubleshooting procedures are listed below. · · · · CAUTIONS: Troubleshooting should be attempted by qualified personnel only. Remember that a battery can cause serious damage if shorted. Do not disassemble the ProStar from its case. There are no user serviceable parts inside the ProStar. Observe all normal precautions when working with energized circuitry. NOTE: There are no internal fuses or circuit-breakers in the ProStar case. There is nothing inside the case that can be adjusted, and there are no consummable parts to replace. 1. Check for proper LED indications on the ProStar. [. . . ] 120°C/140°C ELECTRONIC FUSE / SYSTEM SAFETY · Load short-circuit . . . . . . . . . . . . . . . .
