4.2.4 Fault Indicators

If a fault occurs, the UPS automatically switches to BYPASS mode, ONLY in case of a battery

disconnect fault will the original operating mode be maintained. The fault message alternates with

UPS mode once a second, the red Fault LED illuminates on the control panel and the buzzer sounds

continuously. If a fault occurs, proceed as follows:

Buzzer alarm operation—The buzzer alarm can be switched On or Off.

Clear fault—Present fault condition can be reset if fault condition is cleared, either automatically or

by the operator/technician.

Fault information—A maximum of 4 fault events may be displayed in this window. All fault

displays include: the nature of the fault event, and the time it occurred; the time is relative to the

UPS operating time.

Display faults—The various possible fault indicators are listed in the following table.
