INTRODUCTION
Product Overview
The CB Watch 3 system (often abbreviated as CBW3 in this manual) is a monitoring
system for high voltage circuit breakers. It monitors the following aspects:
▪Operation timing
▪SF6 gas leakage
▪Arcing contact wear
▪Coil circuits
▪Stored energy system (spring or pump)
▪Cabinet / tank heater temperature
A web server HMI is provided to both configure the system and review the data but
various communication protocols are also available to transmit the data to a Historian or
another software system.
Document Scope
This User Manual is intended to explain the various monitoring functionalities of the
CBW3 and how they can be used to monitor a high-voltage circuit breaker. All outputted
information is detailed as well as all the possible alarms that can be set. Communication
and system settings are also covered.
Please refer to the CBWatch3 Installation Manual for information on the various modules
and sensors comprising the CBW3 system. It provides all the necessary information to
install and connect them together and configure the system.
All the available CBW3 monitoring options are detailed in this user manual. Depending on
which configuration has been purchased and installed, all the functionalities described in
this document may not be available.

SYSTEM DESCRIPTION
Modules
The CBW3 system is comprised of both modules and sensors. The modules comprise the
processor module and the various I/O modules. They receive and process the signals
obtained from the sensors.
For more detailed information, please refer to the CBW3 Installation Manual.

2 ProWatch Module 6 AI8-3 Module
3 DI16 Module 7 RTD8 Module
4 AI8-1 Module 8 DO16 Module
Sensors
Depending on your CBW3 configuration, various sensors are connected to the modules,
either directly or through terminal blocs. These sensors acquire the data from the circuit
breaker so that it can be received by the corresponding I/O modules and processed in
the main ProWatch module. Please refer to the Installation Manual for details on sensors.

HUMAN MACHINE INTERFACE (HMI)
Introduction
The CB Watch 3 does not require the user to load a special software to connect to it and
access the information it captures. The CBW3 has a built-in web server and an integrated
Human Machine Interface (HMI) which is accessible from any web browser,
The HMI lets the user configure the system, set alarms and visualise all the measured
parameters, the alarm status and the curves/graphs recorded in memory.
TCP/IP configuration
Before you can access the CBW3’s HMI, you must first configure your network adapter
accordingly. Open Network Connections by clicking the Start button , and then
clicking Control Panel. In the search box, type adapter, and then, under Network and
Sharing Center, click View network connections. And then click “change adapter settings”
Figure 3 –Network card configuration step 1
Right-click the connection that you want to change, and then click Properties. If you're
prompted for an administrator password or confirmation, type the password or provide
confirmation.
