	Hipulse - Single Phase ‘1+N’ UPS System		130 kVA - 110V
14.		BATTERY: E.O.D.	Battery discharge has continued beyond a preset value. The
			inverter will shut down, the system will attempt a transfer to bypass.
			If Bypass is not available, any load connected to the UPS will be
			without power.

	15.	RECT. OFF	The RECT. OFF alarm is active whenever the battery charger
			(rectifier) is not producing its correct output voltage. This can be

caused by an operator selection to OFF, an Input supply failure, an open rectifier a.c. input power switch or an internal fault which may be accompanied by one of the fault conditions.

16.RECT. SWITCH OPEN RECT. CURRENT LIMIT BATTERY: FUSE FAIL DC BUS: FAST OVERVOL

Most of the rectifier fault messages are self explanatory however, the DC BUS: FAST OVERVOLTAGE message informs the operator the d.c. busbar voltage is too high.

17.	BYP. ABSENT	INPUT FAILURE: input a.c. supply failed or out of specified
	BYP. OVERVOLTAGE	acceptable range. Do not switch OFF the inverter while this
	BYP. UNDERVOLTAGE	indication is active or the load will lose its power.
	BYP. FREQUENCY ERROR

18.	BYP. SCR FAILURE	One or more of the static switch SCR’s has developed a fault. The
		bypass would not support the load in the event of a UPS failure,
		immediate action is required. Seek qualified assistance.

19.	BYP. PHASE ROT. ERROR	This message informs the operator that the input power lines have
		been cross-connected and the phases sequence is incorrect.

20.	MANUAL BYPASS CLOSED	This is a status warning that the load is being powered through the
		maintenance bypass line and is unprotected from mains supply
		aberrations.

21.	INV. UNSYNCHRONIZED	This warns that the inverter is not synchronized with the bypass
		supply, which is normally due to a problem with the bypass supply
		being outside an acceptable frequency window. Do not switch OFF
		the inverter when this alarm is active or the load will experience a
		200 millisecond power break.
