This information may be amended orsupplemented by technical and commercialrequirements.05 02 24ENGLISHUsing a serial link RS485 you can connect the QI-POWER-485-300 with the interface program FACILE QI-POWER-485. Using this software, allows you to set theModbus address, baud rate, delay, the TV and TA ratio,modify the measuring filter type (from fastest response timeto better accuracy) and the frequency measurement oncurrent channel instead of voltage channel. You candownload the FACILE QI-POWER-485 free of charge fromour website https://qeed.it/en/software-drivers/.Alternatively it is possible to program QI-POWER-485-300via RS485 Modbus RTU accesing the MODBUS RegisterMap directly. (Available from the page of the product orfrom https://qeed.it/en/documents-manuals/).MOUNTING:the Power Meter QI-POWER-485-300 can be mounted(see photo on the right) horizontally or vertically using thescrews or by means of the provided DIN rail clips.INSTRUCTION MANUAL QI-POWER-485-300INSTRUCTION MANUAL QI-POWER-485-300Energy storage data on flash memory: 4,5 years minimum,45 years typical.Measurement refresh: every 50 cycles or 1 second (thefaster), programmable by FACILE.Minimum value of Current / Power measured (cut off):configurable with FACILE1) tool in range [0…10200 mA] /[0…10200 W]2) (see register map3 - register 40013 - for moredetails).1) Not allowed values entered with FACILE tool are automatically rounded to theclosed lower admissible value2) [0…2550 mA] / [0…2550 W] for products with FW prior to FW373) For FW prior FW37 refer to OLD_register_map, starting from FW37 refer toNEW_register_mapBAUDRATE SETTING DIP 1 DIP 2All setting from EEPROM 0 XSet address 1 - 9600 1 0Set sddress 1 - 38400 1 1If you want to configure the device with FACILE set the dip-switches to 0 (down). In order to configure the device via RS485directly, set "DIP 1" to 1 (up) then the adjust "DIP 2" for baudratesetting. Save the configuration using the COMMAND register.Restore default dip switches setting (down 0) to use theEEPROM configuration.FACILE QI-POWER-485The free interface program FACILE QI-POWER-485 is thefastest way to configure the device. There is only oneconfiguration screen (see picture shown). The changes made tothe program act on the register of the QI-POWER-485-300. Torestore the default configuration, press the button FACTORYDEFAULT.MEASURING MODE: allows selection between RMS or DC todefine the sign, positive or negative, of measure.ENERGY SAVING ON FLASH: it is possible to activate thesaving of the counters directly on the device’s flash memory.FREQUENCY MEASURING CHANNEL: possibility to selectcurrent or voltage channel to calculate the frequency.TRANSFORMATION RATIO: in case of use of CT or VT, youcan define the transformation ratio for the current input andvoltage input; default ratio is 1:1.FILTER: allows to set a filter on measurement reading in order toget faster response time (value 1) or a more stable andaccurate measurement (value 5 ). Default value is set to 2.MIN CURRENT THRESHOLD (mA): Allow you to set theminimum current value (Cut off). Under this value the devicemeasure zero. For more details, refer to box above.MIN POWER THRESHOLD (W): Allow you to set the minimumpower value (Cut off). Under this value the device measure zero.For more details, refer to box above.CAUTION: magnetic fields of high intensity can vary the values measured by thetransformer. Avoid installation near permanent magnets, electromagnets or ironmasses that induces strong changes in the magnetic field. If case of anomalies it isrecommend orienting or moving the transformer in a more suitable area.The protection offered by the device canbe compromised in case it is not usedaccording to the instructions.2REMARKS:• Modbus connections: A+ and B- as per ModbusRTU standards• Modbus Register reference: withreference to the logical address, for ex. 40010,corresponds to physical address n°9 as perModbus RTU standard;• Modbus functions supported: 3 (Read multipleregisters, max 100), 6 (Write single), 16 (Writemultiple);• Any changes made by dip-switchrequired to switch off the power supply orsending reset command.
