Info

Lock: indicate a breakdown of the UPS or one of its parts. Locks are normally preceded by an alarm signal. In theevent of a fault and resultant breakdown of the inverter, the inverter will be switched off and the load will be powered bythe bypass line (this procedure is excluded for breakdowns caused by high and persistent overloads and by shortcircuits).CODEL01L02L03L04L05L06L07L08L09L10L11L12L13L14L15L16L17L18L19L20L21L22L23L24L25L26L27L28L29L30L31L34L35L36L37L38L39L40L41L42L43L44DESCRIPTIONIncorrect auxiliary power supplyOne or more internal cables disconnectedPhase 1 input fuse broken or input relay locked (will not close)Phase 2 input fuse broken or input relay locked (will not close)Phase 3 input fuse broken or input relay locked (will not close)BOOST stage overvoltage positiveBOOST stage overvoltage negativeBOOST stage undervoltage positiveBOOST stage undervoltage negativeStatic bypass switch faultL1 bypass output breakdownL2 bypass output breakdownL3 bypass output breakdownPhase1 inverter overvoltagePhase2 inverter overvoltagePhase3 inverter overvoltagePhase1 inverter undervoltagePhase2 inverter undervoltagePhase3 inverter undervoltageDirect voltage at output of inverter or Sine wave of Phase1 inverter distortedDirect voltage at output of inverter or Sine wave of Phase2 inverter distortedDirect voltage at output of inverter or Sine wave of Phase3 inverter distortedOverload at output of Phase1Overload at output of Phase2Overload at output of Phase3Short circuit at output of Phase1Short circuit at output of Phase2Short circuit at output of Phase3Phase 1 output fuse broken or output relay locked (will not close)Phase 2 output fuse broken or output relay locked (will not close)Phase 3 output fuse broken or output relay locked (will not close)Heat sink Phase 1 overtemperatureHeat sink Phase 2 overtemperatureHeat sink Phase 3 overtemperatureBattery charger overtermperatureTemperature probe of heat sink Phase 1 faultyTemperature probe of heat sink Phase 2 faultyTemperature probe of heat sink Phase 3 faultyTemperature probe of battery charger faultyBOOST battery 1 fuse blownBOOST battery 2 fuse blownBOOST battery 3 fuse blown
