Operation and Maintenance Manual

5-2

Possible causes:

•Inspect the PV array for ground faults.

•CT8 defective: Troubleshoot the ground fault CT8, located on the power distribution panel of the main

enclosure (see system schematic drawing in Section 7), using the procedures described in fault YY27.

0032 - PV Overvoltage (S)

The PV voltage has exceeded the maximum programmed limit (PV Max Volt).

Check the PV input voltage at the PV disconnect switch. If the voltage is below 600 VDC, clear the

alarm and restart the PV-225208.

0040 - In Programming Mode (S)

System is in reload PROM mode.

0042 - Bad Memory (S)

The static memory test failed upon system initialization. This fault is generally transient in nature.

Attempt to clear the fault by either cycling control power or pressing the black reset button in the lower

left corner of the PCU. If the fault is sustained, replacement or service of the PCU will be necessary.

0045 – Line Matrix Failure to Turn On (S)

0046 – Line Matrix Failure to Turn Off (S)

Software was not able turn on or turn off the indicated switching matrix.

Attempt to clear the fault by either cycling control power or pressing the black reset button in the lower

left corner of the PCU. If the fault is sustained, replacement or service of the PCU will be necessary.

0061 – Line AC Frequency Too Low (S)

The AC line frequency fell below the allowable limit.

This fault is self-clearing. Once the utility frequency has recovered within the acceptable operating

range, the PV-225208 will automatically clear this fault and resume normal operation after 5 minutes. If the

fault will not clear, verify the adjustable setpoint is below the actual utility frequency. If the fault is sustained,

contact your Xantrex Technology distributor for assistance or service.

0062 - Line AC Frequency Too High (S)

The AC frequency exceeded the allowable limit.

This fault is self-clearing. Once the utility frequency has recovered within the acceptable operating

range, the PV-225208 will automatically clear this fault and resume normal operation after 5 minutes. If the

fault will not clear, verify the adjustable setpoint is above the actual utility frequency. If the fault is sustained,

contact your Xantrex Technology distributor for assistance or service.
