Matrix Test
This operating state is provided to verify proper operation of the matrix and
associated control electronics. In this state, the CCU2 will send digitized gating
signals (On/Off) to the IGBTs at a 2 Hz rate. There is no power transfer between
the PV and utility in this mode. The
ON
/
OFF
switch must be in the
OFF
position for
the GT100 to enter this state.
Fault
The GT100 has encountered a fault condition. When this happens, regardless of
the GT100 state of operation, the GT100 will stop processing all power and
execute an orderly system shutdown. A description of the fault and fault code will
appear on the operator interface VFD. The Fault state may be cleared from the
keypad once the cause of the fault has been corrected. See Chapter 4,
“Troubleshooting” for a complete description of all fault codes.
See next page for the Operating States Flow Chart for Power Tracking.
