GB D 22.433.910 – Version 3.00 OVERWIEV Single phase direct connection up to 65 A (Imax) MID approval (WM1M6) Class 1 for active energy according to EN 62053‐21 and B according to EN 50470‐3 Class 2 for reactive energy according to EN 62053‐23 Reference frequency 50 and 60 Hz Pulse output according to EN 62053‐31 A&B (option) Serial RS485 communication (option) Tariff input (option) Display LCD 7+1 digit (100 Wh resolution) Multifunctional front LED 2 DIN‐rail width mounting according to EN 60715 Sealable terminal cover External bistable switch control (option) APPLICATION The meters WM1‐6 and WM1M6 are intended for energy measurements in single‐phase electrical power network and can be used in residential, industrial and utility applications. Meters measure energy directly in 2‐wire networks according to the principle of fast sampling of voltage and current signals. A built‐in microprocessor calculates energy and other electrical quantities from the measured signals. It also controls LCD, LED and installed modules. Housing is provided with terminals protection covers, which can be sealed up against non‐authorised access. They are built to be fastened to EN 60715 standard guides. Meters have built‐in optical (IR) communication port on the side as a standard. Special WM‐USB adapter (size 1 DIN module) can easily be attached to it. It can be used for direct communication with PC to change settings of devices without RS485 communication. Optional the meters can be equipped with a RS485 serial communication with the MODBUS protocol, which enables data transmission and thus connection of the measuring places into the network for the control and management with energy. RS485 serial communication can be used together with optical (IR) communication in order to control a bistable swhitch Iskra BICOM. They can also be equipped with tariff input (option). A built‐in pulse output (option) is designed for sending data to the devices for checking and monitoring consumed energy. Picture 1: Meter parts Page 3 to 17 TECHNICAL DESCRIPTION 4
GB D 22.433.910 – Version 3.00 LAYOUT AND MODE OF OPERATION Picture 2: Block diagram The meter is supplied from the measuring system using the capacitor power supply (1). For current input the shunt resistor is applied (2).Voltage is measured by the resistor voltage divider (3). A method for sampling voltages and currents with an A/D converter is used. For signal processing the dedicated measuring microcontroller is used – SoC (System on a Chip) (4). Amplifiers for current signal and A/D converters are integrated in the SoC. Basic meter data, parameters and calibration constants are stored in the EEPROM (5). There are no adjustable elements (potentiometers) in the meter, which assures a better long‐term stability. SoC drives directly also the LCD (6) for displaying of 4 energy registers and actual values of other electrical parameters (voltage, current, frequency, active, reactive and apparent power and power factor). One (optional) S0 output (11) can be built into the meter. A number of pulses depend on consumed energy. LED diode (8) is used for indication of no load condition and test output proportional to measured active energy. IR communication (7) using MODBUS protocol is equipped on each meter. It can be used for setting and testing the meter using WM‐USB adapter. Galvanic separated communication (9, 10) RS485 (optional) also enables setting the meter, data readout in the network and tariff setting. Tariff can also be set via tariff input (12) (option).

Monitoring power supply supports storing of energy registers to EEPROM. • Supported protocol is MODBUS. MODBUS table containing all the codes is present for read/write and read‐only registers. See Table 2: MODBUS register map • UART0 in microcontroller communicate via isolated RS485 driver to network if a 485 board is present. There are 5 different baud rates possible for RS485 communication. o 1200 bits/s o 2400 bits/s o 4800 bits/s o 9600 bits/s o 19200 bits/s • UART1 in microcontroller communicate via isolated Infrared driver to network. IR communication is provided by default and is always set to a baud rate of 19200 bits/s. • Installed EEPROM is used to store settings and registers. • Watchdog is present. If program fails it is used to reset the meter. • Metering functions are done with compute engine (CE). Each 250 ms, firmware is transforming the values of these registers to human readable values. There are four different energy counters, which can be configured each to measure one of seven different types of energy. For MID meters, this energy counters are configured only in production. For Non‐MID counters they can be also reconfigured during use. These are: o Total Absolute Active Energy (kWh) o Total Absolute Reactive Energy (kvarh) o Total Absolute Apparent Energy (kVAh) o Import Active Energy (kWh) o Export Active Energy (kWh) o Import Reactive Energy (kvarh) o Export Reactive Energy (kvarh) The energy register is a count of pulses. The number of CE units per pulse is a constant in the meter calibration data. Function add () adds the current interval’s power data to a “remainder” variable. If this variable is larger than one pulse, then the number of pulses is added to the energy register, and remainder variable is decreased by the number of CE units that represent the same amount of energy. • LCD contents are updated every 250 ms. Parameters which can be shown are: Energy registers: o Energy counter 1 (mandatory) o Energy counter 2 o Energy counter 3 o Energy counter 4 Actual measured values: o Active Power o Reactive Power o Apparent Power o Power Factor o Voltage o Frequency o Current Page 6 to 17 TECHNICAL DESCRIPTION GB D 22.433.910 – Version 3.00 Parameters cycle from 5 to 60 seconds for each parameter. Cycling time and the definition of parameters for LCD scrolling are configured via RS485 or IR communication. • Display description: 1. Tariff setting for displayed counter / actual tariff 2.

Info: kVAh display A – Currently active counter S – Apparent power PF – Power factor U – Voltage F – Frequency I – Current 7. W – active power var – reactive power 8. Inductive / capacitive Energy counter displays (up to 4 counters) are displaying current energy counter settings (tariff, import / export / total, active / reactive / apparent), its value and actual activity (counting (A) / not counting ( )). Other displays are displaying actual value of measured quantity (P‐W, Q‐var, S, PF, U, f and I), direction of active energy flow (import / export), reactance (inductive / capacitive) and active tariff (regarding tariff input). • Energy registers are displayed with resolution 7 + 1 (kWh, kvarh and kVAh). The meter can be set to Test measuring mode which displays energy registers with better resolution. The test mode is used for test purposes during type testing and test of meter constant during initial verification. After power off meter automatically goes back to normal operation. • Test output is provided as LED with number of impulses proportional to active energy. Pulse constant is 1000 imp/kWh. Optionally the S0 impulse output with the same constant can be used for active energy. Pulse output is defined to be 32 ±2 ms long according EN 62053‐31. • Energy measurement is blocked for the currents less than 20 mA. The meter measures actual voltage and frequency. Current and power values are set to zero and there is no energy registration. No load condition is indicated with the LED on. • If measured voltage is under 170 V, the energy measurements are also blocked and communication is disabled. LCD stops to cycle and displays only value of voltage. Page 7 to 17 TECHNICAL DESCRIPTION GB D 22.433.910 – Version 3.00 Software functions: • Identification – SW version can be read using RS 485 or IR communication. The check sum (CRC) of complete firmware is calculated and displayed during initialization and later it can be read from the MODBUS register. If CRC for code is changed and does not correspond to the initial CRC, an ERROR is detected during startup and ERROR 2 is shown on the LCD. This is checked after every restart of the meter. • MID SW is separated from non MID SW – MID versions are 2.xx as non MID versions are 1.xx • Calibration parameters can only be changed in production. They can not be changed by upgrade or different processes. Special factory software is used to calibrate the parameters for current, voltage, phase angle and linearity. If these parameters were tenaciously or accidentally changed, an error type 1 is detected and ERROR 1 is shown on the LCD. Calibration parameters are checked every 10 minutes for consistency and if error is found, ERROR 1 is immediately shown on LCD. • It is possible to upgrade the firmware via factory software protocol. This option is available only for WM1‐6 (non MID) type of meter. • There is an option for a password to protect the instrument. Password has four levels of protection. Meter has possibility of two level user defined password (4 characters from A to Z). • Password Level 1 – enables resetting the counters and tariff setting. • Password Level 2 – enables all available settings and resets. If meter password is forgotten, device serial number should be sent to Iskra Sistemi, d.d. to receive device default password. • Software for handling MODBUS protocol is written. Hardware timer is used for calculating the time needed to read and answer a MODBUS protocol message. RTU mode is used. RTU messages start and end with a silent interval of at least 3,5 character times (t1‐t2‐t3‐t4 as shown below). Each message must be transmitted in a continuous stream. If a silent interval of more than1,5 character times occurs before completion of the frame, the device flushes the incomplete message and assumes that the next byte will be the address field of a new message. Cyclic Redundancy Check (CRC) is used. • All parameterization is done via communication with MiQen software (version 2.1 or later). WM1M6 (MID) has limited parameterization. Counter settings, tariff setting and counter reset are not enabled. If these settings on WM1M6 (MID) were tenaciously or accidentally changed, an error type 1 is detected and ERROR 1 is shown on the LCD. Settings are checked every 10 minutes for consistency and if error is found, ERROR 1 is immediately shown on LCD. • Firmware allows also user defined parameterization software using MODBUS protocol with specified MODBUS registers.
