Fast AC Voltage
High
S
This fault indicates that the utility
grid voltage is above or rose above
the maximum allowed value of
120% (Fixed) of nominal Vac for
greater than 10 cycles (Fixed). 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
rose above the
allowable limit.
0094
Ambient
Temperature
S
This fault indicates that the GT100
has detected that the temperature of
the ambient air within the intake
ducting use for Inverter ventilation
has exceeded either the minimum or
maximum allowed values of -20 and
55 °C respectively. This fault is
Auto-Clearing once the ambient
