7Startup sequenceInstruction manual IM1002004E September 2015 www.powerquality.eaton.comStartup sequenceWARNINGThere are dangerously high voltages present withinthe enclosure of the power supply system. Cautionmust be taken when working with the enclosure. It isrecommended that all work be performed by qualifiedelectrical personnel only.otes:N Initial startup should be performed with no-loadon system.1. Re-install all panels that may have been removedduring installation.2. Make sure the input circuit breaker is in the OFF position.3. Energize the primary building power.4. Turn on the main AC input breaker.5. Verify that the output voltage is within thespecified range.6. Verify output phase rotation is correct.7. Turn the system off.8. Connect the loads one at a time and repeat Step 5.Preventive maintenanceWARNINGDanger of electrical shock. Turn off all power supplyingthis equipment prior to maintenance.To ensure longer component life and trouble-free operation,minor preventive maintenance procedures should beperformed at regular intervals, for example once everyyear. More frequent inspection intervals would be neededfor more severe operating conditions and larger number ofhours of continuous operation.A. Remove top and side panels and at each serviceinspection any accumulated dust, dirt or foreign particlesshould be carefully removed. Special care should beexercised in cleaning the thyristors, heat sinks, and thecontrol assembly.B. Inverse parallel silicon rectifiers (SCRs) or thyristors:The silicon controlled rectifiers (SCRs) usually fail in theshorted mode. When this happens, normally the fusiblelink in series with the SCR will be blown open to clearthe short and prevent damage to the transformers. Theindividual SCR can be checked with an ohmmeter. Referto page 8 for resistance checking procedures.C. Replace top and side panels. Turn unit on with no load.D. Turn on loads.E. Check to verify all fans are operational.otes:N Preventive maintenance plans are included onpage 38 of the manual.General troubleshooting guideTable 4. General Troubleshooting GuideSymptom Probable causes1. No output on one ormore phasesA. Blown fuseB. Defective SCR or power moduleC. Defective control cardD. Defective sense cardE. No input2. Output is too high or too low A. Control card adjustmentB. Defective control cardC. Defective sense cardD. Defective SCR or power moduleE. Input out of range3. Input breaker tripping off A. Defective breakerB. System overloadedC. Over/undervoltage detection is shuttingdown system (see symptom #2)D. Defective over/under detection cardE. Shorted taps4. Blowing semi-conductor fuses A. Shorted SCRs or power modulesB. Output loads shorted5. No output voltage A. Defective over/under outputdetection PCBWARNINGThere are dangerously high voltages present withinthe enclosure of the power supply system. Under nocircumstances should any person reach within theenclosure of this equipment. All service to this pieceof equipment should be performed by qualifiedpersonnel only.Troubleshootingotes:N Circuit diagrams in this manual are for reference only.Always refer to the actual circuit diagrams receivedwith the system.IntroductionThis procedure is written in a specific order and must beused from start to finish when troubleshooting. Any stepsskipped over may cause serious damage to the system. |
