0080 Left Matrix Not ON S This fault indicates that the PV225S
has detected that the left IGBT matrix
(FPGA) was not enabled after having
sent a command for it to turn on. The
CCU2 sends an acknowledge bit to
confirm the command is received.
This fault is primarily a watch-dog
between software and hardware to
ensure control of the left IGBT matrix
(FPGA).
