Table 4-1Fault Codes

Error		Fault Type
		H=Hardware
Code	Fault Source(s)	S=Software	Fault Description		Possible Causes
XX51	Right 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 PV225S has detected that an			is loose or disconnected
			IGBT gate drive fault has occurred in		•	IPM internal error
			the right matrix. An internal			condition
			protection circuit within 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:
			•	0151 (A+)
			•	0251 (A–)
			•	0451 (B+)
			•	0851 (B–)
			•	1051 (C+)
			•	2051 (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.
XX60	Left Matrix	S	This fault indicates that the PV225S		• Fuses F15 or F16 blown
	Temperature		has detected that the temperature of		•	External cooling fan
			the left IGBT matrix aluminum			inoperable
			heatsink has exceeded the maximum		• Air flow on heat sink
			allowed value of 95 °C.			impeded due to
						accumulation of debris
					•	Operation above rated
						ambient temperature for
						an extended period of
						time
