WM15
Introduction
WM15 is a power analyser for single-, two- and three-phase systems. MID models can be used for fiscal metrology in three-
phase systems.
Depending on the model, WM15 is equipped with a static output (pulse or alarm), with a static output and a Modbus RTU com-
munication port or with a static output and a M-Bus port.
The self-powered version can be installed on systems with voltage up to 415 V L-L (400 V L-L for MID models), while the ver-
sion with auxiliary power supply can be installed on systems with voltage up to 600 V L-L.

UCS (Universal Conguration Software)
UCS is available in desktop and mobile versions.
It may connect to WM15 via RS485 (RTU protocol, desktop version only) or through OptoProg (via Bluetooth).
UCS allows to:
• set up the WM15 unit (online or offline);
• display the system state for diagnostic and setup verification purposes
Overview of the UCS functions:
• Setting up the system with WM15 connected (online setup)
• Defining the setup with WM15 non connected, then applying it at a later time (offline setup)
• Displaying the main measurements
• Displaying the state of inputs and outputs
• Displaying the state of the alarms
• Recording the measurements of selected variables (UCS Desktop version only)
• Displaying the quick help on installing WM15 and connecting with OptoProg (UCS Mobile version only)

Input, output and communication
Digital output
The digital output can perform two functions:
Function Description Parameters
Alarm Output associated with the alarm Output state when no alarm is active
Pulse output Pulse transmission output for imported active energy consumptions. • Pulse weight
• Pulse duration
Modbus RTU port (OS version)
Modbus RTU communication port is used to transmit data to a Modbus master (Carlo Gavazzi UWP3.0 or any SCADA, PLC, BMS, etc).
For further information about Modbus RTU communication refer to the communication protocol.
M-Bus port (OM version)
M-Bus communication port is used to transmit data to a M-Bus master (Carlo Gavazzi SIU-MBM or any third party M-Bus master).
For further information about M-Bus communication refer to the communication protocol.
Optical port and OptoProg
The optical port allows to set up the WM15 unit and to read the data through UCS (from PC) or mobile UCS (da smartphone Android) without
connecting to the communication network to which the analyser is connected. You need to purchase OptoProg, the Carlo Gavazzi optical
interface device for communication via micro USB or via Bluetooth.

19WM15 - User manual | CARLO GAVAZZI Controls SpA
Essential information
dmd values
Average value calculation (dmd)
WM15 calculates the average values of the electrical variables within a set integration interval (15 min by default).
Integration interval
The integration interval starts at switch-on or when the reset command is issued. The first value is displayed at the end of the first integration
interval.
Example
The following is a sample integration:
• reset at 10:13:07
• set integration time: 15 min.
The first value displayed at 10:28:07 refers to the interval from 10:13:07 to 10:28:07.
Alarms
Introduction
WM15 manages a measured variable alarm. To set the alarm, define:
• the variable to be monitored (VARIABLE)
• alarm activation threshold value (SET POINT 1)
• alarm deactivation threshold value (SET POINT 2)
• alarm activation delay (ACTIVATION DELAY)
Variables
The unit can monitor one of the following variables:
• system active power
• system apparent power
• system reactive power
• system power factor
• phase-neutral voltage (OR logic)
• phase-phase voltage (OR logic)
• current (OR logic)
Note: if you select a current or a voltage, WM15 simultaneously monitors all the phases available in the set measurement system and triggers
the alarm when at least one of the phases is in alarm (OR logic)
Alarm types
Up alarm (Set point 1 ≥ Set point 2)
The alarm activates when the monitored variable exceeds the Set 1 value for a time equal to the activation delay (Delay) and deactivates
when the values drops below Set 2.

when it exceeds Set 2.

LCD display
Home page
The unit may display the default measurement pages when the Home button is pressed (starting from any measurement page) or after no
operation has been performed for five minutes, if the screensaver is enabled and the screensaver type is set by UCS to “Home page” (default
value).
Notes: if you select a page that is not available in the set system, the unit displays as its home page the first available page. In MID models the
home page cannot be changed and displays the active energy meter.
Backlight
The WM15 unit is equipped with a backlight system. You can set whether the backlight shall always be ON or whether it should automatically
switch off after a given interval has elapsed since a button was pressed (1 to 60 minutes).
Screensaver
If the SCREENSAVER function is enabled (default setting), after 5 minutes have elapsed since a button was pressed the unit will display the
home page if the screensaver type is “Home page” (default setting), or it shall activate the slideshow function, which displays the selected
pages on a rotating basis
Notes: the screensaver type and the slideshow function with the relevant pages can only be set up through the UCS software or the UCS
Mobile app. In MID models the screensaver setting is “Homepage” and cannot be changed.
Page lter
The page filter makes it easier to use and browse the measurement pages. When you use the / buttons, the unit shall only display
the pages you are most interested in, which can be selected through the UCS software or the UCS Mobile app.
Note: to display all the pages without using the UCS software or app, you can disable the page filter from the SETTINGS MENU (DISPLAY →
PAGE FILTER → OFF). By default, the pages included in the filter are: 1, 10, 13, 16, 17, 21, 22, 26, see “Measurement pages” on page 14.
Restoring the factory settings
Restoring the settings using the RESET menu
From the RESET menu you can restore all the factory settings. At start-up the QUICK SET-UP and WIRING CHECK menu shall be available
again.
Notes: meters are not reset. In MID models you cannot reset the CT current transformer ratio (CT RATIO).
Restoring the settings using the reset button
Press for at least five seconds the reset button (located near the current inputs) to access the menu, restore all the factory settings and reset
