DTSU666 Three phase electronic energy meter user manual 1.Overview of products 1.1 Applicable range The DTSU666 meter mainly applied into the measurement and display for the photovoltaic system parameters in the electric circuit including voltage, current, power, frequency, power factor, active energy, etc. The network can be realized through RS485 communication interface and external device. Adopting the standard DIN35mm din rail mounting and modular design, it is characterized with small volume, easy installation and easy networking. 1.2 Specification for product model 3.Instructions for installation 3.1 Check the Package Check whether the product shell in the carton is damaged, if is, please contact the supplier 3.2 Installation Directly clip the instrument on the rail and install it on the distribution box. (1)When installing, firstly clip one terminal of the slot and then clip to the rail with power. (standard DIN35mm) (2)When disassembling, press the movable card with a screwdriver and take out the instrument.

Abnormal data for the electrical parameter Wrong wiring Elimination 1.If it is wrongly connected, please reconnect based on the right wiring mode (see the wiring diagram). 2.If the supplied voltage is abnormal, please choose the specified voltage. 1.If there is any problem with the communication cable, please change it. 2.Set the address, baud rate, data bit and check bit through buttons and confirm it is the same with the host computer, then set the operation to be "parameter settings". If wrongly connected, please connect the voltage of phase A, B and C to the wiring terminal of the instrument 5. Meter setting Button description: "SET" button represents "confirmation", or "cursor shift" (when input digits), "ESC" button represents "exit", "" button represents "add". The input code is (default 701). The factory default value of the baud rate is 9600adress is 1. There is no need to set, if you need to change as follows: When input digits, " " can be used as cursor " "motion button; " "is "add" button, " "is Exit the programming operation interface or switch to the character interface from digit modification interface, add from the beginning after setting the digit to the maximum value. 6.Export limitation function setting 6.1 The steps for matching R5 series (1)Download eSolar O&M APP Web to eSolar website https://fop.saj-electric.com to scan the QR code and download "eSolar O&M" APP (or download it from Google Play or App Store by searching "eSolar O&M"). After the installation on your phone, please login it with your installer account. (2)Log in APP Click "My" Click "Remote control" Click "WiFi" /"Bluetooth" Click "Next step". as shown in Figure6.1.
