Troubleshooting

Faults and Fault Codes

Fault states are automatic from any state of operation. In the event of a fault condition, the PV225S will immediately stop processing power and execute an immediate orderly shutdown, open both the main AC and DC contactors, and remain in a faulted state until the fault is remedied and cleared (manually or automatically).

In the event of an alarm or fault condition, the PV225S will execute an immediate, orderly shutdown and remain in a faulted state until the alarm or fault is remedied and cleared (manually or automatically).

•Faults associated with a grid disturbance clear automatically. The PV225S will automatically re-start after a 5-minute delay.

•All other faults must be cleared manually.

All fault conditions arising from within the PV225S are reported to the UFCU (Universal Frontpanel Control Unit). The 4-line LCD will display a hexadecimal value (fault code) and a brief text description of the fault.

Most faults are latching and only those faults associated with grid disturbances are auto-clearing and thus enable the PV225S to restart after a 5 minute delay period.

Once the cause of the fault has been identified and corrected, and it is determined to be safe to proceed, PV225S faults may be manually cleared from the UFCU keypad or using the remote GUI.

See “Clearing Faults Manually” on page 4–3 for instructions on this procedure.

General Troubleshooting

Respond to any PV225S alarm or fault as follows:

1.Note and document the alarm or fault code and brief text description.

2.Determine the source of the alarm or fault by referring to Table 4-1, “Fault Codes” on page 4–4.

3.Rectify the alarm or fault condition and attempt to clear the fault from the display. See “Clearing Faults Manually” on page 4–3 for instructions on this procedure.

4.If the condition is sustained and cannot be corrected, again note and document the fault code and description, and contact either your Distributor / Reseller, or Xantrex Customer Service.

WARNING: Lethal Voltage

In order to remove all sources of voltage from the PV225S, the incoming power must be de-energized at the source. This may be done at the Utility main circuit breaker, and by opening the AC disconnect and the DC disconnect switches on the PV225S. Review the system configuration to determine all of the possible sources of energy. In addition, allow 5 minutes for the DC bus capacitors, located on the ceiling of the cabinet, to discharge after removing power.
