Manual State Transitions
State conditions can also be transitioned manually. Refer to “Commanding Goal
State Changes” on page 2–22 for instructions on commanding GT100 goal states
for manual transitions.

1. Turn the
O
N
/O
FF
switch to the
O
FF
position.
2. Command the GT100 to the Matrix Test.
3. After completing the Matrix Test, command the GT100 to Shutdown.
If the
O
N
/O
FF
switch is turned to
O
N
while the GT100 is in the Matrix Test state,
the GT100 will transition to Shutdown.

Power Tracking or Shutdown
1. Verify the PV manual current parameter (
I Manual %
) is set to the desired
percent of rated.
2. Command the GT100 to Manual Current mode from the operator interface
keypad. While in the manual current mode, the user may change the PV
manual current parameter. However, the user may demand greater current
than the capacity of the PV array. If this causes the PV voltage to drop below
the minimum operating voltage (300 Vdc), the GT100 will transition to
Shutdown.
3. To exit the Manual Current mode, the user must manually command the
GT100 to Power Tracking.
Automatic State Transitions
State conditions can also be transitioned automatically. Refer to “Commanding
Goal State Changes” on page 2–22 for instructions on commanding GT100 goal
states.

1. The
O
N
/O
FF
switch must be turned to the
O
N
position.
2. Once the PV voltage exceeds the PV voltage start set point (
PV V Start
)
the GT100 will start a wake-up timer (
PV T Start
).
a) If the PV voltage remains above the PV start voltage set point for the
duration of the wake-up timer, the GT100 will transition to Power Track-
ing.
b) If the PV power drops below the PV power stop set point, (
PV P Stop
)
the GT100 will start a PV sleep timer (
PV T Stop
).
c) If the PV voltage and power remain below their respective setpoints for
the duration of the sleep timer, the GT100 will transition to Shutdown.
