Troubleshooting
Symptom
Possible Cause - What to Check
The EMS does not activate, does not
display any information, or the system
does not activate.
This is typically caused by low or no voltage from the batteries.
Check both of the fuses. See the maintenance section of this manual for fuse
information.
Using a volt meter, measure the battery voltage. It should have a reading of 12.0 V
or greater. If the voltage is very low, charge or replace the batteries and monitor the
system for proper operation. Ensure that the R247-E solar engine is clean, clear of
debris, and is not shaded by buildings or vegetation. If the solar panel is covered or
shaded, this will prevent proper battery charging. Once the batteries have proper
voltage, check the EMS for error codes and run the 'bISt' function. See the 'EMS
Programming and Testing' section of this manual.
The LED module will not fl ash.
This can be caused by either a wiring issue, low battery voltage, or the unlikely event
of an EMS failure.
Check the wiring to the LED module and make sure the wires are not pinched
anywhere along their length.
Check the OBUI for errors. See the 'EMS Programming and Testing' section of this
manual.
The LED module is dim when fl ashing.
The battery voltage may be too low for proper operation and the system has activated
the Automatic Light Control (ALC). Check the OBUI for ALC status and battery
voltage. See the 'EMS Programming and Testing' section of this manual. Ensure that
the R247-E solar engine is clean, clear of debris, and is not shaded by buildings or
vegetation. If the solar panel is covered or shaded, this will prevent proper battery
charging and drive the system into ALC.
Check for debris covering the ambient light sensor on top of the solar engine.
Check the OBUI Solar (SoLr) setting to ensure it is detecting light ("dAY" not "nItE").
Check the Factory Set LED brightness setting (FACt). Consult Carmanah prior to
changing this setting as the LED brightness is set based on the solar location.
Check the ambient light auto-adjust (AAA) setting on the OBUI. Turn off the AAA to
see if this corrects the dim LED Module. See the 'EMS Programming and Testing'
section of this manual.
The LED module appear too bright when
fl ashing.
Settings on the EMS can affect the apparent brightness of the LED module.
See the 'EMS Programming and Testing' section of this manual.
