TROUBLESHOOTING ECU OPERATION
Problem: IP shows “60.190.131.228”
If the IP address displayed on the ECU’s LED shows “60.190.131.228”, the
ECU did not successfully obtain a DHCP IP address from the router.
Solution: Check network connectivity to the router or other DHCP server.
Typically this means that the ECU is not communicating with the router.
You may need to contact the Internet provider, or refer to the router’s
documentation for troubleshooting assistance.
Problem: -Web
If the ECU’s LED is displaying “-web”, the ECU is not communicating
with the APsystems monitoring system.
Solution: Reboot the ECU by unplugging the power cord for at lease
seven (7) seconds, and plugging it back in. If the LED still indicates
“-web”, check network connectivity to the router. You may need to
contact the Internet provider, or refer to the router’s documentation for
troubleshooting assistance.
Problem: “!” following Reporting Inverters number
If the reporting inverters number is followed by an “!”, then the number
of reporting inverters does not match the number of UIDs that have been
programmed into the ECU (see Managing Inverter UIDs pg. 20). This may
indicate the ECU is having difculty communicating with the inverters, or
that light levels are too low to energize the system.
Solution: Plug the ECU into a different dedicated electrical socket.
