Table 4-1Fault Codes

Error		Fault Type
		H=Hardware
Code	Fault Source(s)	S=Software	Fault Description		Possible Causes
0047	Software Test	S	This fault indicates that the PV100S
			has detected that a software test fault
			has occurred. This is a simulated fault
			used for debugging purposes.
0048	Bad Memory	S	This fault indicates that the PV100S		•	Internal SRAM error
			has detected that the SRAM DIMM		•	CPU error
			on the CCU2 controller board has
			failed. The CCU2 performs a series
			of tests to confirm the validity of the
			SRAM, and the memory module has
			produced errors.
XX52	Matrix Gate	S	The CCU2 controller sends digitized		•	Fiber-optic harness is
			timing signals for gating the IGBT’s			loose or disconnected
			via the IPM driver board and bi-		• PS1 ±15 Vdc Power
			directional fiber optic			Supply is defective
			communication. This fault indicates		• P1 on IPM driver board
			that the PV100S has detected that an			is loose or disconnected
			IGBT gate drive fault has occurred.		•	IPM internal error
			An internal protection circuit within			condition
			the individual IPM devices of the
			IGBT matrix also generates a gate
			fault as the result of either short
			circuit, over current, over
			temperature, or an under voltage
			condition.
			The first two digits of the fault code
			indicate the particular IGBT that
			reported the fault, as follows:
			•	0152 (A+)
			•	0252 (A–)
			•	0452 (B+)
			•	0852 (B–)
			•	1052 (C+)
			•	2052 (C–)

If more than one IGBT faults simultaneously, the two first digits are added in hexadecimal form to indicate that the gate drive fault has occurred in more than one phase, thus the error code will contain the summation of the faulted phases.
