Faults and Fault Codes
Fault states are automatic from any state of operation. In the event of a fault
condition, the PV100S 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 PV100S 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 PV100S
will automatically re-start after a 5-minute delay.
•
All other faults must be cleared manually.
All fault conditions arising from within the PV100S
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 PV100S 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, PV100S 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 PV100S 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 PV100S, 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 PV100S. 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.
