CAPACITOR C1CAPACITY LOWThe main DC-capacitor needs replacement due to aging or failureLOADnotPROTECTEDINVERTER OFFDue to a failure the output converter's output is not available. As a result theload may have been transferred to bypass.LOADnotPROTECTEDBATTERY DEPLETEDLOADnotPROTECTEDBATTERY LOWThe remaining runtime is zero. As a result the load may have been transferredto bypass.The remaining runtime is less than the set time (standard 2 minutes). This textalternates with the following screen:UPS SHUTDOWNLEFT 2 MINUTESBYPASS ERRORFUSE FAILUREINPUT ERRORFUSE FAILUREINTERNAL BATTERYFUSE FAILUREThe output voltage can be lost after the indicated time due to dischargedbattery. Controlled shutdown of any computer equipment is absolutelynecessary at this point. (Using the RS232 or SNMP communications interface,this procedure can be initiated automatically on unattended systems). If theUPS operates at 100% load, the shutdown procedure should be completedwithin 2 minutes after the 'battery low' alarm started. When the batteries arefully discharged, the UPS is no longer able to power the connected equipment.The static bypass MCB (rear panel, 9) is in 'off' (down position): no bypassvoltage available. Mains voltage is available. If not manually operated, this mayhave been caused by an overload situation.The mains MCB (rear panel, 8) is in the 'off' (down position): no line voltageavailable, bypass voltage is available. If not manually operated, this may havebeen caused by an internal system failure.The internal battery fuse is defective; this may have been caused by aninternal system failure. This alarm also appears if no batteries are installed.EXTERNAL BATTERYFUSE FAILUREThe (custom-built) battery extension set has been disconnected from thesystem: its energy reserve is not available. See 4.5.2 or 4.5.4 step 9 for details.REPLACE BATTERYINPUT out LIMITS137V 50.0HzThe batteries are (almost) chemically worn out. If the batteries are aged, theymust be replaced as soon as possible to ensure full protection for yourequipment (see section 8.3).The mains voltage or mains frequency are outside UPS input tolerance (seechapter 10, specifications)BYPASSoutLIMITS197V 50.0HzINPUT AND OUTPUTNOT SYNCHRONIZEDAUTONOMY TIMELEFT 0:09:41The mains voltage or mains frequency are outside bypass input tolerance butinside UPS (rectifier) input tolerance (see chapter 10, specifications). Bypassoperation is inhibited: if for whatever reason the output converter is unable todeliver the required output, output power is lost.The output converter frequency is not synchronized to the mains (input)frequency. In this situation the automatic bypass switch is not able to transferthe load from output converter to bypass and reverse: automatic bypassoperation is inhibited: if for whatever reason the output converter is unable todeliver the required output, output power is lost. (see section 3.4).Synchronization is only possible if the mains frequency remains withincertain limits (see chapter 10).The remaining runtime. This figure is counted down during battery operationuntil either the mains returns or the batteries are depleted.OPM_LPE_11X_3K0_10K_1GB_V041 21 GE DE LP 11 UPS: User manual 4.1 (GB)
