TROUBLESHOOTING

GENERAL

In the event of a fault, the PV-30208 will annunciate the condition at the operator interface. The PV- 30208 will execute an orderly shutdown and remain faulted until the fault is cleared (manually or auto- matically).

In general, the operator should respond to any PV-30208 fault as follows:

1.The source of the fault should be sought by referring to the following chart.

2.Rectify the fault condition and attempt to clear the fault by cycling the on/off switch.

3.If the problem cannot be corrected, note and write down the fault code and description, then contact your Xantrex Technology distributor for assistance or service.

FAULT CONDITIONS

LCD Fault Annunciation

The LCD interface reports fault conditions on Line 2 and 3. The fault code number will follow a text description. The fault description will remain displayed until the fault has been corrected and cleared. Each fault is described on the following page.

Fault Clearing

Faults may be cleared automatically by the PV-30208 or manually by the operator depending upon the type of fault. The utility protection faults (over/under AC line voltage and frequency) are self-clearing fault conditions. Once the utility voltage and frequency returns within allowable operating ranges, for a period of five minutes, the PV-30208 will clear the fault and resume normal operation.

Latching faults must be cleared manually by the system operator. Once the cause of the fault condition has been corrected, the fault may be cleared with the on/off switch. First turn the switch to the off position and then back to the on position in order to reset the inverter. If a fault is sustained, the inverter will not reset, and will continue to report the fault. If the fault has been corrected, the LCD will return to the normal display, and the PV-30208 will resume normal operation.
