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).
Once the utility recovers and remains within the excursion limits for a period set
by the Auto-Clear Delay (ID 60), the GT100 will automatically clear the fault and
resume normal operation.
In addition, the Air Duct Intake Over and Under-temperature faults will also self-
clear automatically.
•
0094 (Ambient Temperature)
All other faults associated with the GT100 must be identified, corrected and then
cleared manually using the UFCU or GUI. The following procedure describes
how to manually clear a fault message from the VFD.
To clear the fault:
1. Determine the source of the fault using Table 4-1, “Fault Codes” on page 4–5.
Correct the fault condition.
2. Ensure the fault code and “
Clear Fault?
” message is displayed in the VFD.
a) If the “
Clear Fault?
” message is not shown on the second line of the VFD,
scroll through the read parameter menu with the
/\
or
\/
keys until the mes-
sage appears.
3. To clear the fault, press <
E
NTER
>. The GT100 will immediately transition to
Power Tracking mode.
