15 control-panel display general organization The display is structured around primaryand secondary messages, measuringtables and setting screens. As a rule, themessage displayed on the screen isalways a primary one. The secondarymessages, if any, are accessed by press-ing keys 9 ▼ and 10 ▼ (see fig...

16 list of primary messages LOAD PROTECTEDON-LINE MODE This is the normal display when there areno alarms or problems and the load is cor-rectly supplied by the inverter, in on-linemode. LOAD PROTECTEDPARALLEL ON-LINE MODE This is the normal display when there areno alarms or problems and the load i...

19 measurement system The display may be used to read a num-ber of input and output measurementsmade at different points in the system.See figure 18 . ■ normal AC source 1 ❏ phase-to-phase voltages, ❏ currents of the three phases, ❏ frequency; ■ bypass AC source 2 ❏ phase-to-neutral voltage, ❏ phase...

22 general The auto diagnostic system considers anysystem status other than normal as aproblem.Before taking any action, note down themessages displayed on the control panel.Certain problems may prevent the controlpanel from functioning.In this case, it is strongly recommend-ed to call the MGE UPS S...

23 environment information Terminals XR2, XR3, XR4 and XR5 on the"Media Contacts 11" board of each type ofunit can be used to receive signals fromthe operating environment and to transmitsignals concerning the operating status ofthe UPS (see figure 16 for the position ofthe board, item 12). ...

24 presentation of eventtime-stamping by GalaxyPW™ Time-stamping of events by Galaxy PW™makes it possible to: ■ log the events; ■ consult the last 500 events that occurred on the Galaxy PW™ UPS; ■ consult general statistical data on UPS operation; utilization via the GalaxyPW™ display main menu The ...

27 The battery capacity is the value mea-sured by the UPS microprocessor. It isexpressed in Ampere-hours. This valuechanges over time depending on the para-meters of the battery itself and its environ-ment. This measurement is used to checkthat the battery is capable of supplying therated power in t...

28 maintenance configuration single-UPS unit See figure 19. During maintenance, theUPS must be isolated from the normal andbypass AC source, the battery and theload. ■ UPS isolation Proceed in the following order (see figure20): ❏ shut down the inverter (press the "invert- er OFF" button 8 f...

31 Galvanic isolation andvoltage matching transformers The UPS can be equipped with an isola-tion or auto transformer on both the inputand output to provide galvanic isolation orvoltage step-up or step-down as required.
