Xantrex Technology GT3.0 owner manual VoltageFault, 8Fault Message Screens

										Front Panel Display Screens and What They Mean
Fault Mode causes	These message screens only appear when there is a fault, and then flash
	alternately with the Inverter Offline default screen (Table 5-5) until the fault is
	corrected.
	Table 5-8Fault Message Screens
				Display						Description
										When the actual DC voltage is over or under the allowable
										range, 165 to 600 Vdc. Self-clearing, no action required.
										The PV array should be configured such that DC voltage
										does not fall below 195 Vdc or rise above 600 Vdc.*
			VoltageFault							When the actual AC voltage is over or under the allowable
										range, as specified in “Output” on page A–2.
										This is a utility fault; it will clear itself when the AC voltage
										comes within the specified range.†
										When the actual Frequency is over or under the allowable
										range, as specified in “Output” on page A–2. This is a utility
										fault; it will clear itself when the frequency comes within the
		e								specified range.
										When the unit’s†internal temperature is greater than 80° C
										(176° F), the unit will shut down automatically and only
										restart when the temperature has dropped to less than 70° C
										(158° F).
	DCA			145.5V						When a grounding fault is detected. The ground fault fuse
										will be blown. The system must be shut down completely,
										the fault corrected, the fuse replaced (see “Replacing the
										Ground Fault Protection Fuse” on page 6–4) and then the
										system restarted. Troubleshooting a grounding fault should
			Detected							be performed by qualified personnel.
