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 Operating 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.
Important note: All the available CBW3 monitoring options are detailed in this Operating
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 include the main
processor module and the various I/O modules. They receive and process the signals
obtained from all the sensors.
For more detailed information, please refer to the CBW3 Installation Manual.

1 Power supply 5 AI8-2 Module
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.
