What does 3F25 fault mean on a PV100-208 or 3F25\3F26 on a PV225-208?

Issue:
Unit faulted on 3F25 or 3F26

Product Line:
PV100-208 or PV225-208

Environment:

Cause:
No LED on any of the three phases of the driver board

Resolution:
The power supply, PS1, provides 15VDC to the driver board. If the power supply is bad, no LED will be present. Check the power supply fuses F9 and F10 to see if they are blown or not. If blown, replace them and see if the fault can be cleared. If the replacement did not fix the issue or the fuses are blown again, call 866-519-1470 and select option 3 and 3 to open a case.
