Matrix Over Current H
This fault indicates that the GT100
has detected that the AC current on
one or more phases of the IGBT
matrix has exceeded the maximum
allowed value of 1400A
rms
.
The first two digits of the fault code
indicate the particular phase where
the over current occurred as follows:
• 0130 - Matrix over current in
phase A
• 0230 - Matrix over current in
phase B
• 0430 - Matrix over current in
phase C
If more than one phase faults
simultaneously, the two first digits
are added in hexadecimal form to
indicate an over current condition in
more than one phase, thus the error
code will contain the summation of
the faulted phases.
• P3 or P1002 on CCU2
is loose or
disconnected
• AC system wiring
short
0033
Ground Over
Current
S
This fault indicates that the GT100
has detected that the ground fault
current has exceeded the maximum
allowed value. This maximum
allowed value for ground fault
current is 4 Adc.
• P3 or P2 on CCU2 is
loose or disconnected
• Ground -to-AC or
DC-to-System wiring
short
• F4 is blown
• F4 fuse holder is open
