Single-phase electrical energy meter WM1M6
DESCRIPTION
The meters WM1-6, WM1-6Z, and WM1M6 (MID certified) are intended for energy
measurements in single-phase electrical power networks 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,
power, and power factor from the measured signals. It also controls LCD (WM1-6
and WM1M6 only), LED, and installed modules.
Housing is provided with terminals protection covers, which can be sealed up
against non-authorized access. They are built to be fastened to EN 60715
standard guides.

INSTALLATION
- To prevent electrical shock and/or equipment damage, disconnect electrical power at the main fuse or circuit breaker before installation or any servicing.
- Make sure, that no voltage is present in the installation.
- Prevent the disconnecting device from being switched on accidentally.
- Connect the module according to the electrical diagram. WM1-6Z has a built-in antenna.
- Please install WM1-6Z as far as possible from metal elements.
NOTE!
Module installation requires a great degree of skill and may be performed only
by a qualified and licensed electrician.
Even when the module is turned off, the voltage may be present on its
terminals. Any work on configuration changes related to connection mode or
load must be always performed by a disconnected power supply (disable the
fuse).
Do not connect the module to loads exceeding recommended values. Connect the
module only in accordance to the below diagrams. Improper connections may be
dangerous. The electrical installation must be protected by overcurrent
protection fuse 65 A and rated breaking capacity 1500 V (ESKA 522.7..) must be
used according to wiring diagram to achieve appropriate overload protection of
the module.

2.2 Connection of modules
Meter can be equipped with different modules. WM1-6 & WM1M6
RS485 serial communication with the MODBUS protocol enables data transmission
and thus the connection of the measuring places into the network for the
control and management with energy. They can also be equipped with tariff
input (option). Both supported only on WM1-6 and WM1M6.
A built-in pulse output (option) is designed for sending data to the devices
for checking and monitoring consumed energy.
Triac output for triggering an external relay. Supported only on WM1-6Z.
Check labels on the side of the meter to check what modules are built-in.
It is possible to connect two external modules. One is controlled by a built-
in optical (IR) communication port on the side, the second is controlled by
Triac output.
The picture above indicates the connection of two external relays to WM1-6Z.
BICOM432-40-WM1 connected via optical (IR) communication port and IKA232-20
connected via Triac output.
COMMUNICATION
3.1 RS485
Galvanic separated serial RS485 communication module can be built-in. There
are 5 different baud rates possible for RS485 communication:
- 1200 bits/s
- 2400 bits/s
- 4800 bits/s
- 9600 bits/s (factory default)
- 19200 bits/s
It uses the MODBUS RTU protocol to read and change the settings of the meter
and to read measuring results. RS485 serial communication can be used together
with optical (IR) communication in order to control a bistable switch Iskra
BICOM.
NOTE!
WM1-6Z does not support RS485 communication.
3.2 Optical IR
Meter has a built-in optical (IR) communication port on the side as a
standard. A 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. Communication settings for WM-USB are
fixed to:
Communication speed,……………….. 19200 bit/s
Frame………………………….. 8, none, 2
Address…………………… 33
Drivers for WM USB are installed automatically when MiQen 2.1 software is
installed. If not, it is possible to install them manually from …” MiQen 2.1
installation folder” / Drivers.
NOTE!
Supported on all variants of WM1 (WM1-6, WM1-6Z, and WM1M6).
NOTE!
Supported only on WM1-6Z.
Z-Wave is a wireless communications protocol for home automation. It is
oriented to the residential control and automation market. A Z-Wave automation
system can be remotely controlled via the Internet, using a Z-Wave gateway or
central control device which serves as both the Z-Wave hub controller and
portal to the outside.
Module Inclusion (Adding to Z-wave network)
- Connect module to the power supply
- Enable add/remove on the main controller
- auto-inclusion (works for about 5 seconds after connected to power supply) or
- press service button S for more than 2 second
NOTE!
For the auto-inclusion procedure, first set the main controller into inclusion
mode and then connect the module to the power supply.
Module Exclusion/Reset (Removing from Z-Wave network)
- Connect module to the power supply.
- Bring module within a maximum of 1 meter (3 feet) of the main controller.
- Enable add/remove mode on the main controller.
- Press service button S for more than 6 seconds.
By this function, all parameters of the module are set to default values and
their own ID is deleted.
If service button S is pressed more than 2 and less than 6 seconds module is
excluded, but configuration parameters are not set to default values.
Association
Association enables Smart meter module to transfer commands inside Z-Wave
network directly to other Z-Wave modules.
Associated Groups:
Group 1: Lifeline group (reserved for communication with the main controller),
1 node allowed.

order to increase the reliability of the network.
MEASUREMENTS
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, these energy counters are configured only in production. For Non-MID counters, they can be also reconfigured during use. These are:
- Total Absolute Active Energy (kWh)
- Total Absolute Reactive Energy (vary)
- Total Absolute Apparent Energy (HVAC)
- Import Active Energy (kWh)
- Export Active Energy (kWh)
- Import Reactive Energy (vary)
- Export Reactive Energy (vary)
Actual measured values:
- Active Power
- Reactive Power
- Apparent Power
- Power Factor
- Voltage
- Frequency
- Current
5. INPUT AND OUTPUT MODULES
As an option device can have built-in:
- Tariff input that supports measurement of energy in two tariffs. When there is the voltage on it (check values in technical data) it stores data in Tariff 2 registers otherwise in Tariff 1 registers. Tariffs can be set via communication by MiQen software. Supported on WM1-6 and WM1M6.
- Pulse (SO) output module that counts absolute active energy with a fixed pulse rate 1 imp/Wh.
- Triac output/Digital input for triggering an external relay. Supported only on WM1-6Z.
6. LCD
NOTE!
No LCD display on WM1-6Z.
On LCD measured data are presented. Display scrolls automatically. Displayed
quantities and scroll time can be set via communication by MiQen software.

7. LED
Multifunctional LED counting pulses for Active Energy 1 imp/Wh. If constantly
lit indicates no load (I < 0,02A).
8. SETTINGS
All parameterization can be done via communication with MiQen software
(version 2.1 or later). WM1M6 (MID) has limited parameterization. Counter
settings and counter reset are not enabled.
With MiQen software meter can be set to Test measuring mode that displays
measurements with a precision of 2 digits. After powering off meter
automatically goes back to normal operation.
8.1 Security – password
Meter has the possibility of a two-level password (4 characters from A to Z).
Password Level 1 – enables resetting the counters.
Password Level 2 – enables all available settings and resets.
If the meter password is forgotten, the device serial number should be sent to
Iskra d.d. to receive the device’s default password.
SERVICE AND MAINTENANCE
If the meter is used under specified conditions, it should not be necessary to
recalibrate it during its lifetime. If degradation in the performance is
observed it has probably been partly damaged and should be sent for repair or
exchanged. In the meter firmware and parameter control function is integrated.
In case of ERROR 1 or ERROR
2 indication on LCD the meter should be returned to the manufacturer.
9.1 Firmware upgrade
The firmware upgrade is only possible for the WM1-6 (non-MID) and WM1-6Z type
meters. The upgrade is done via proprietary software using an optical IR
communication port.
NOTE!
Do not interrupt the power supply or communication line during the upgrade –
the device could become inoperative! Repairing of the device, in this case, is
to be done by authorized service.
