Introduction

Description

WM50 is a multichannel power analyzer for single, two and three-phase systems. Using TCD12 split core current sensors, it can

monitor up to 96 single-phase loads or any combination of single and three-phase loads or two and single-phase loads for a

maximum of 96 channels. The system can be set up, measurements viewed and up to 16 alarms managed from WM50 and UCS.

Main unit functions can be expanded with a maximum of two of the following available modules: digital input/output module, analog

input module and communication module.

Components

Component Description

WM50 Main unit, measures and displays the main line electrical variables via current sensors. With LCD display and

touch keypad, it lets you set measurements parameters, configure accessory modules and manage up to 16

alarms. It communicates with TCD12 current sensors via pre-installed MABC module to monitor up to 96

channels.

Accessory

modules

(optional)

Connected to the main unit via local bus, the following expand WM50 functions:

Type Module description Part number

Digital inputs/outputs Six digital inputs and six static outputs M F I6 O6

Six digital inputs and four relay outputs M F I6 R4

Analog inputs Three analog inputs (neutral current, temperature probe, 20 mA input) M A TPN

Communication Modbus RTU communication on RS485/RS232 M C 485 232

Modbus TCP/IP communication on Ethernet M C ETH

TCD12 12-channel current sensor. Measures main electrical variables on the single channels and loads and transmits

them to WM50. A maximum of eight TCD12s can be connected in series on two TCD buses to each WM50 via

TCD12WS cables.

UCS Configuration and diagnostics software. Available for both PC and Android mobile devices.

Managed measurements

Introduction

WM50 calculates and displays both main line and single channel and load measurements.

All measurements are displayed by UCS or via Modbus communications (Carlo Gavazzi VMU-C monitoring system or other data

acquisition system). Main line measurements are also available on screen.

Main line measurements

Note: the following values are available for all measurements: minimum, maximum, average (dmd) and maximum average (max

dmd). The available variables depend on the type of system set. Minimum and maximum values are calculated only considering

valid values and not out of range values.

Minimum and maximum values are calculated only

considering valid values and not out of range values.

Note: a Modbus protocol table can be set from UCS to

customize and facilitate TCD12 variable reading. See

"Download" on page1, “Modbus communication protocol” for

further information.

Measurement management

Measurement error

If a measurement is not available or out of range, it is displayed as "EEEE" on WM50 display and as "--" on UCS. See

"Troubleshooting" on page36

Average value calculation (dmd)

The system calculates the average value of electrical variables in a set integration interval (15 min by default). The average value

will not be available if the variable measurement is out of range. By default, the integration interval is calculated from when the

analyzer is turned on. To guarantee calculation alignment, it can be synchronized using the internal clock. In turn, the internal clock

can be synchronized with an external reference via digital input (i.e.: from the electric manufacturer's device).
