Troubleshooting

This unit provides 5 LED indicators to help diagnose any problems. The following table lists the meanings of the LEDs

and tips for troubleshooting the issues they indicate

LED Indication

OVERTEMP

Indicates that the voltage converter is running too hot.

The unit will shut down until it cools. There may be too many devices drawing from the

converter or is it located in a poorly ventilated area. Try disconnecting some devices or

remounting the unit if this persists.

INPUT UNDER VOLTAGE

Indicates that the input voltage is not high enough for the unit to operate normally.

Ensure the power source is supplying the correct voltage. Check that the input connection

and wires have not been damaged or corroded. If these factors are in working order, the

cause is likely an internal component failure and the unit will have to be returned for service.

OUTPUT UNDER VOLTAGE

Indicates that the output voltage is higher has dropped to <50% the regulated output

voltage.

There is likely too much load is being drawn from the converter and the voltage is dropping

to try and maintain the output current. Reduce the load on the system by disconnecting or

turning off some of the connected devices. Check that the output connection and wires have

not been damaged or corroded.

OVERLOAD

Indicates that load is drawing too much current from the converter.

The unit has been operating at it’s peak output current for too long. Reduce the load on the

system by disconnecting or turning off some of the connected devices.

POWER ON

Indicates that the converter is being supplied with power and operating.
