Fault
If the GT100 encounters a fault, regardless of operating state, it will transition to
the Fault state. The GT100 will remain in this state until the fault condition has
been remedied and cleared. The Fault Code number will appear on the first line of
the VFD. A description of the fault will show on the second line. The third line of
the VFD will read “
F1 to Clear Fault?
”. The fourth line shows the
goal state.
To clear the fault:
1. See Table 4-1, “Fault Codes” on page 4–5 for a complete listing of Fault
Codes and possible remedies. Correct the fault condition if possible and
attempt to clear the fault by pressing “
F1
”.
2. The ability to clear the fault can only be done from the
R
EAD
Menu. If a fault
occurs while accessing the
W
RITE
Menu, pressing <
M
ENU
> once will return
to the Read Menu, and “
F1 to Clear Fault
” will appear on the third line
of the VFD display.
Auto-restart Feature
In the event of an Air Duct Intake temperature excursion beyond -20 to 55° C, or a
utility voltage or frequency excursion outside of those specified in
Table A-4 on
page A–4, the
GT100 will automatically transition to a Fault condition. Once the
Air Duct Intake temperature recovers and remains within the excursion limits for
a period of five minutes, and/or the utility voltage and frequency 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, then resume normal operation.
