Clearing Faults Manually
Faults associated with a grid disturbance clear automatically. These faults include:
• 0010 (AC Frequency Low),
• 0011 (AC Frequency High),
• 0012 AC Voltage Low), and
• 0013 (AC Voltage High) only.
Once the AC voltage and frequency return to within the acceptable range, the
PV100S will clear the fault and automatically restart after a 5-minute delay. All
other faults associated with the PV100S must be circumvented and cleared
manually using the UFCU.The following procedure describes how to manually
clear a fault message from the LCD.
To clear the fault:
1. Determine the source of the fault using Table 4-1, “Fault Codes” on page 4–4.
Correct the fault condition.
2. Ensure the fault code and “
Clear Fault?” message is displayed in the LCD.
a) 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.
3. To clear the fault, press <E
NTER>. The PV100S will transition to Sleeping
mode.
