Troubleshooting Error Codes - Clarion XC7420 Owners & Installation Manual

TROUBLESHOOTING - ERROR CODES
Clarion XC7 amplifi ers use a microcontroller to manage the operation of the amplifi er.
Included in the fi rmware is the ability to detect errors in the functionality of the amplifi er.
The following error code chart can be used to look up the cause of a fault.
Code 1 - Power Supply Under Voltage
Code 2 - Channel 1-4 Short Circuit
Code 3 - Repeated Short Circuit
Code 4 - Power Supply Over Voltage
Code 5 - DC Voltage Speaker Protection
Code 6 - Channel 5 Short Circuit
Over Temperature - Heatsink
Over Temperature - Power Supply

The following codes are shown by a red fl ashing pattern of the Power/Protect LED.
Code 1 - Indicates that the power connection voltage is too low. Check all your power
connections. This is most commonly caused by a poor ground connection.
Code 2 - There is an over-current condition on Channel 1-4. This could be caused by a
shorted speaker, a grounded speaker wire or an internal fault. Disconnect all speaker
wires and test again.
Code 3 - The amplifi er has detected the occurrence of short circuits on the last three
power-up attempts. Correct this condition, remove power from the amplifi er for 15 minutes
and try again.
Code 4 - Indicates that the battery connection voltage is too high. Check the functionality
of the vehicle charging system.
Code 5 - This error indicates that there is a DC voltage present on one of the speaker
leads. The amplifi er will need to be serviced.
Code 6 - There is an over-current condition on Channel 5 of the XC7520. This could be
caused by a shorted speaker, a grounded speaker wire or an internal fault. Disconnect all
speaker wires and test again.
Heatsink Over Temperature - This error indicates that the chassis of the amplifi er has
exceeded the recommended operating voltage. Review your choice of installation location,
ensuring that there is adequate airfl ow around the amplifi er. Also check your wiring to
make sure the amplifi er is getting enough voltage and has a good ground connection.
Power Supply Over-Temperature - This error indicates that the power supply of the
amplifi er has exceeded the recommended operating voltage. Ensure that the amplifi er is
getting adequate voltage.
