Operating States
A state machine implemented within the CCU2 control software governs the
operation of the GT100 with clearly defined transitions between its operating
states. There are five steady-state operating states and numerous intermediate
transition states.

Matrix Test
•
Fault
The user should be aware of the following conditions governing GT100
state transitions:
•
Qualified utility voltage must be present for all states of operation.
•
Fault states are automatic from any state of operation. A fault will cause the
GT100 to immediately stop processing all power. The fault condition will be
reported to the operator interface VFD.
•
Most GT100 faults are latching and must be cleared at the operator interface
keypad before transitioning to another operating state.
•
The
ON
/
OFF
switch, located on the front door of the GT100, must be in the
ON
position for all operating states except Matrix Test, in which case it must be in
the
OFF
position.
