Possible causes:
•
The PV array open circuit voltage exceeded 600 VDC.
•
There is a problem with the PV voltage sense wiring (see system schematic in Section 7).
(10) Internal System Fault
There has been an internal system fault. Contact your Xantrex/Trace Technologies distributor.
Possible cause:
•
There is a problem with the integrated bus board or DSP control board.
Emergency Stop Fault
The on/off switch, located on the front door of the enclosure is disabled. The contact block on the back
of the switch must be open for the PV-15208 to report this message.
If the switch is enabled and the red indicator light is still on, isolate the PV-15208 from external power,
then:
•
Verify continuity across the switch contact block while the switch is turned to the on position.
•
Verify continuity between P7-1 and P7-2 while the switch is enabled.
This message will display on the second line of the LCD display. It does not indicate a system fault if the
on/off switch is turned to the off position.
