SECTION 4
OPERATION
Any State → Fault:
•
If the PV-100208 encounters a fault, regardless of operating state, it will transition to the Fault
state. The PV-100208 will remain in this state until the fault condition has been remedied and
cleared via the front panel.
A description of the fault will show on the first line of the operator interface LCD. The second line
of the LCD will read 'Clear Fault?'. To clear a fault press <ENTER>. The PV-100208 will transi-
tion to Sleeping. If the fault does not clear, the fault condition has not been corrected. If the 'Clear
Fault?' message is not shown on the second line of the LCD, scroll through the read parameter
menu with the /\ or \/ keys until the message appears.
AUTO-RESTART FEATURE
In the event of a utility voltage or frequency surge or sag, which causes the inverter to shut down, the
PV-100208 will automatically transition to a fault condition. Once the utility recovers for a period of
five minutes, the PV-100208 will automatically clear the fault, then resume normal operation.
ISOLATION PROCEDURE
The following procedure should be followed to de-energize the PV-100208 for maintenance:
1.
Turn the On/Off switch to the Off position.
2.
Open the PV array disconnect switches.
3.
Open the AC disconnect switch.
4.
Open the isolation transformer circuit breaker.
5.
Install lockout devices on the isolation transformer circuit breaker and PV disconnect switch.
The terminals of the disconnect switches may be energized if the arrays are ener-
gized. In addition, allow 5 minutes for all capacitors within the main enclosure to
discharge after disconnecting the PV-100208 from AC and DC sources.
TURN-ON PROCEDURE
Refer to Section 3 for a detailed first-time turn on procedure.
1. Remove any lockout devices from the isolation transformer circuit breaker and PV disconnect
switch.
2. Close the isolation transformer circuit breaker.
3. Close the AC disconnect switch.
4. Close PV array disconnect switches.
5. Turn the On/Off switch to the On position.
After a 15 second initialization period, the PV-100208 will automatically transition to 'Waking Up',
given the PV voltage is greater than the PV V Start setpoint.
