Wärtsilä JOVYSTAR HP 200-800kVA BAX 4640 E - 34 -7 BLANK The load is supplied directly by the mains through the manual bypassswitch. The UPS is isolated.CAUTION:Even at switched off input mains, a dangerous high voltage is still present inside the UPS!NOTE:The load is powered now by the mains. Any blackout in the mains will lead to a blackout for the loads.5.5.1 Start-up from manual bypass (Single UPS)Before the start-up from manual by-pass (after maintenance or repairing) check that the “NORMAL-BYPASS” switch is inBYPASS position.Nr. LCD DISPLAY ACTION UPS OPERATION1 BLANK Close RCB2 BOOT LOADING “BOOT” phase where the UPS firmware can be updated following theappropriate procedure. All the LED’s on the front panel are on.3 EEPROM READING Reading of the configuration parameters stored in the EEPROM.All the LED’s on the front panel are off.2 UPS START UPWAIT PLEASEThe rectifier is supplied and the DC voltage reaches the nominal value.All the LED’s on the front panel are on.The microprocessor checks that all the start-up conditions are good forrestart.Led #1 lit green. Led #8 lit orange.5 RECTIFIER START UPWAIT PLEASEThe IGBT rectifier bridge starts to modulate; VDC voltage reaches thenominal value. LED #3 is lit green: DC voltage present.6 START UP FROM MBCBCLOSE BCB Close SBCB7 BYPASS START UPWAIT PLEASEThe microprocessor checks that all the bypass parameters (voltage,phase rotation, frequency) are within tolerance. Led #2 lit green. Thestatic bypass switch is closed. LED #6 lit orange.8 START UP FROM MBCBCLOSE BCB Close BCB Closing of the battery circuit breaker.Led #4 lit green.9 START UP FROM MBCBCLOSE OCB Close OCB The load is fed by the static bypass switch. Circuit breaker MBCB is stillclosed. Led #7 lit green.10 START UP FROM MBCBOPEN MBCB Open MBCB The load is fed by the static bypass switch and the inverter can be start-ed. LED #8 off.11 INVERTER STARTWAIT PLEASEThe modulation of the inverter bridge is started. The AC voltage reachesthe nominal value. The microprocessor checks the synchronization withthe bypass line.12 START UP FROM MBCBMOVE BYP - SWITCHMove the selector“NORMAL-BYPASS” toNORMALThe load is transferred to the inverter. Led #5 lit green.13 START UP ENDWAIT PLEASEThe microprocessor checks that all the output parameters (voltage,current, frequency) are within the tolerance limits.14 UPS MODELOUTPUT Poweri
