KW2G / KW2G-H Eco-POWER METER1209.7 Self-diagnostic functionIf an error occurs, the following indication will be given.Indicator Meaning Output status To recoverErr0 CPU errorOFFTurn the power off and then on again.Err1 Memory error* EEPROM life ended. Replace the unit.*Includes the possibility that the EEPROM’s life has expired.9.8 Power Failure MemoryEco-POWER METER memories integrated electric power and working status to internal EEPROM untilwhen power supply is off. (Power failure guarantee)And every time to change each setting, each setting value is memorized to internal EEPROM at thesame time. Therefore, change setting frequently makes EEPROM’s life short. Avoid to usage like this.*Especially be careful if you set by communication.9.9 Applicable standardSafety standard EN61010-1EMCEMIEN61326-1Radiation interference field strengthNoise terminal voltageCISPR11 class ACISPR11 class AEMSEN61326-1Static discharge immunity EN61000-4-2RF electromagnetic field immunity EN61000-4-3EFT/B immunity EN61000-4-4Surge immunity EN61000-4-5Conductivity noise immunity EN61000-4-6Power frequency magnetic field immunity EN61000-4-8Voltage dip / Instantaneous stop /Voltage fluctuation immunityEN61000-4-11
