Manual State Transitions
State conditions can also be transitioned manually. Refer to “Commanding Goal
State Changes” on page 2–20 for instructions on commanding PV100S goal states
for manual transitions.

Shutdown
1. Turn the O
N
/O
FF
switch to the O
FF
position.
2. Command the PV100S to the Matrix Test.
3. After completing the Matrix Test, command the PV100S to Shutdown.
If the
O
N
/O
FF
switch is turned to O
N
while the PV100S is in the Matrix Test state,
the PV100S 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 PV100S 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 PV100S will transition to
Shutdown.
3. To exit the Manual Current mode, the user must manually command the
PV100S to Power Tracking.
Automatic State Transitions
State conditions can also be transitioned automatically. Refer to “Commanding
Goal State Changes” on page 2–20 for instructions on commanding PV100S goal
states.

Shutdown
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
PV100S 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 PV100S will transition to Power
Tracking.
b) If the PV power drops below the PV power stop set point, (
PV P Stop
)
the PV100S 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 PV100S will transition to Shutdown.
