71769_SC315Solar_GenIII_UserManual_RevC© 2014, Carmanah Technologies CorporationSC315 SOLAR LED RRFB USER MANUALTROUBLESHOOTING29TroubleshootingSymptom Possible Cause - What to CheckThe EMS does not activate, does not displayany information, or the system does notactivate.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 properoperation. Ensure that the solar panel is clean, clear of debris, and is not shaded by buildingsor 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.LEDs won't flash when button on same postis pressedThis can be caused by either button failure, a wiring issue, low battery voltage, or the unlikelyevent of an EMS failure.Check to insure that the button is functioning and it is providing the typical feedback. If thebutton has an LED or audio feedback, ensure that these are working.Check the wiring to the button for continuity and make sure the wires are not pinched anywherealong their length.Check the wiring to the LED Light Bars for continuity and make sure the wires are not pinchedanywhere along their length.Check that the wiring pattern (polarity) is correct on the LED Light Bars.Check the battery voltage, either through the OBUI or with a voltmeter (see item above)Check the OBUI for errors. See the EMS Programming and Testing section of this manual.Test the system using the OBUI 'tESt' function. See the EMS programming and testing sectionof this manual. If the LEDs flash using the OBUI functions, then the problem is in the button orwiring to the button.LEDs on same post flash, but other systemsin the crosswalk set won't flashThe SC315 communicate via a radio. If one system is activated, but the other systems in thecrosswalk set are not coming on, this points to a radio issue.Ensure that all of the units in a crosswalk set are set to the same radio channel using the OBUI.See the EMS Programming and Testing section of this manual.Ensure that the units in a crosswalk set are not too far apart. The maximum distance forproper radio communication is 500 unobstructed feet. There can be no barriers or obstructionsbetween systems, such as buildings or billboards.One Light Bar flashes, but the other LightBar on the same post does not flashThis is likely caused by improper wiring of the light bars.Ensure that the wire colors match the instructions on the Rectangular Flashers and in thismanual. If they do not match then one light bar may not activate.One Rectangular Flasher flashes, but theother Rectangular Flasher on the same lightbar does not flashThis is likely caused by incorrect wiring on the LED Light Bars.Check each of the connections at the Rectangular Flashers to ensure correct wiring pattern(polarity).For a Dual Light Bar system with Single Pedestrian Confirmation Lights, ensure that bothconfirmation lights are pointing in opposite directions and that the wiring pattern is followed. |
