Operation and Maintenance Manual

5-3

0063 - AC Voltage Too Low (S)

The AC Inverter voltage fell below the minimum programmed limit (Min AC Volt).

This problem was caused by the utility. Clear the fault and restart the PV-225208.

Possible causes:

•High momentary load which forces the inverter to current limit

•Fuses F1, F2, F3, F4, F5 or F6 blown

•SSR-1 inoperable

•Contactor K1 inoperable

•Utility voltage fell below the allowable limit.

This fault is self-clearing. Once the utility voltage 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 voltage. If the fault is sustained, contact your

Xantrex Technology distributor for assistance or service.

0064 - AC Voltage Too High (S)

The inverter controller voltage exceeded the maximum-programmed limit (Max AC Volt).

Possible causes:

•SSR-1 inoperable

•Contactor K1 inoperable

•Utility voltage exceeded the allowable limit.

This fault is self-clearing. Once the utility voltage 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 voltage. If the fault is sustained, contact your

Xantrex Technology distributor for assistance or service.

012A - Interrupt Time-Out (S)

The PCU was not able to service the interrupt for approximately 1 second.

Attempt to clear the fault and restart the PV-225208 by pressing the black reset button on the lower left corner

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

0230 – Door Interlock Switch Open (H)

The door interlock lock switch located in the inside upper left corner of the main enclosure door is open.

If the switch is closed and the fault still registers on the front panel, isolate the PV-225208 from external power,

then:

• Verify continuity across the switch contact block while the switch is closed.

•Verify continuity between PCU-J2-5 and PCU-J3-3.
