No Faults
N/A
N/A
N/A
0010
AC Frequency Low
S
This fault indicates that the Utility
grid frequency is below or fell below
the minimum allowed value of
59.3 Hz (default) for greater than 10
cycles. This fault is auto-clearing.
Once the Utility grid frequency has
recovered within the acceptable
operating range, the GT100
will
qualify the value and automatically
clear this fault and resume normal
operation after a delay period.
• Utility grid frequency
fell below the
allowable limit
0011
AC Frequency High
S
This fault indicates that the Utility
grid frequency is above or rose
above the maximum allowed value
of 60.5 Hz (default) for greater than
10 cycles. This fault is auto-clearing.
Once the Utility grid frequency has
recovered within the acceptable
operating range, the GT100
will
qualify the value and automatically
clear this fault and resume normal
operation after a delay period.
• Utility grid frequency
rose above the
allowable limit
0012
AC Voltage Low
S
This fault indicates that the utility
grid voltage is below or fell below
the minimum allowed value of 88%
of nominal Vac for greater than 2
seconds. This fault is auto-clearing.
Once the Utility grid voltage has
recovered within the acceptable
operating range, the GT100
will
qualify the value and automatically
clear this fault and resume normal
operation after a delay period.
• Utility grid voltage fell
below the allowable
limit
• Fuses - F4, F5, F6 on
the Inrush Current
Assembly PCB are
blown.
• P1001 on CCU2 is
loose or disconnected
