Troubleshooting
In the event the RMS30/60F fails to turn on after dark (or simulated darkness):
Check that the panel is completely dark. If there is a street-light directly overhead this can
1.
sometimes provide enough light to simulate daytime. If you are using a cover to simulate
darkness ensure that the panel is completely covered and totally dark.
Open the power module lid, remove the fuse in the positive battery connect lead, and measure
2.
the battery voltage across the battery terminals:
If the battery voltage is <11.0Volts contact Urban Solar Corp for assistance.
3.
If the voltage is between 11.0 and 11.9V then the battery needs to be charged before the
4.
lights will activate. When the battery voltage falls to less than 11.9V, the ECM protects the
battery from over-discharge by disconnecting power to the luminaires. Once the system has
had sufficient time and sunlight to recharge and the battery voltage reaches 12.4 Volts, the
ECM will reconnect power to the luminaires, and the system will function normally. Charging
will occur naturally in the field and the unit can be checked again after a few sunny days.
Alternatively a battery charger may be used – please consult Urban Solar Corp.
If the battery voltage is >11.9V the lights should activate.
5.
Ensure the panel is in complete darkness. Remove the fuse from the positive lead of the battery
6.
and check to make sure the fuse is not blown. Replace the fuse if required.
Remove the fuse and wait 10 seconds, then reconnect the fuse. If lights activate then the
7.
problem is solved. Note - this can be repeated up to 5 times to “reboot” the ECM controller.
If the above steps do not restore normal operation, contact Urban Solar for assistance.
