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
has detected that the SRAM DIMM
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.
• Internal SRAM error
• CPU error
XX52
Matrix Gate
S
The CCU2 controller sends digitized
timing signals for gating the IGBT’s
via the IPM driver board and bi-
directional fiber optic
communication. This fault indicates
that the PV100S has detected that an
IGBT gate drive fault has occurred.
An internal 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:
• 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.
• Fiber-optic harness is
loose or disconnected
• PS1 ±15 Vdc Power
Supply is defective
• P1 on IPM driver board
is loose or disconnected
• IPM internal error
condition
