About Arc Guard System

Chapter 1: About Arc Guard System
Introduction Arc Guard System™ TVOC-2 quickly detects an arc and trips the incoming
circuit-breaker. Using light as the main condition, Arc Guard System™ trips
instantaneously. Thanks to this key functional advantage, it overrides all other
protections and delays, which is crucial when reaction times need to be
mesured in milliseconds. The Arc Guard System consists of the Arc Monitor
and optical sensor used for detection of the arc. For some special applica-
tions, an additional current sensing unit can be added. This a measure to
prevent unintentional tripping from strong light, for example, the sun.
The basic function acts in three phases:
•Detection is light passing through an optical sensor.
•Recognition is the Arc Monitor determining the intensity of light.
•Action is the trip contact closing.

Chapter 2: Safety
Introduction This chapter describes the safety principles and procedures to be used when
working with the Arc Guard System or the Arc Monitor.
It does not cover how to design for safety nor how to install safety related
equipment.
The chapter first presents applicable safety standards.
Finally the chapter finishes with information about how to work in safety man-
ner.

Applicable safety standards
Safety standards This product was developed, designed and certified with regard to improved
reliability and integrity by using safety principles and structures according to
IEC 61508, SIL2.
The Arc Monitor has improved safety to fulfill the safety standards specified
in the following directives:
• Environment A relates to low-voltage non public or industrial networks, loca-
tions and installations including highly disturbing sources.
• Environment B relates to low-voltage public networks such as domestic, com-
mercial and light industrial locations, installations. Highly disturbing sources
such as arc welders are not covered by this environment.
Directive: Description:
2006/95/EC Low voltage equipment
2004/108/EC Electromagnetic compatibility
Notice
This product has been designed for environment A. Use of this product in environ-
ment B may cause unwanted electromagnetic disturbances in which case the
user may be required to take adequate mitigation measures.

Safety signs
General This section specifies all dangers that may arise from performing the work
detailed in the manual.
Warning! The Warning symbol warns that an accident will or may occur if the instruc-
tions are not followed.
Warning!
Make sure that the supply voltage has been switched off before connecting!
Working with high voltage is potentially lethal. Persons subjected to high volt-
age may suffer cardiac arrest, burn injuries, or other severe injuries. To avoid
these hazards, do not proceed working before removing the power to the Arc
Guard System.
Arc Guard System and Arc Monitor are designed to protect people and
installation equipment. Install your system components and Arc Monitor
before supplying power.
DIP switches are used to activate Current Sensing Unit (CSU), auto reset and
assigning trip contacts. Changing DIP switch can cause consequences with
the Arc Guard System.
Make sure you understand the consequences of changing DIP switches.
See more information regarding DIP switches the chapter “DIP switches” on
page - 39
Note! The note symbol alerts to important facts and conditions.

Work in safety manner
Safety manner Safe working methods must be used to prevent injuries. The safety equip-
ment must not be disengaged, bypassed or in any other way modified so
that the safety effect ceases.
Handling the Arc
Monitor
The Arc Monitor may only be used for the purposes mentioned in this man-
ual. The Arc Monitor was developed, manufactured, tested and documented
in accordance with applicable safety standards. If you follow the instructions
regarding safety and use as described in this manual, the product will, in the
normal case, neither cause personal injury nor damage to machinery and
equipment.
To avoid malfunctions or damage through improper handling, follow these
instructions during transportation, installation and maintenance:
• Transport with care. Do not drop, throw, or give the Arc Monitor a strong
shock. It can cause breakage or failure.
• Handle with care. Do not drop, throw, or give the Arc Monitor a strong shock.
It can cause breakage or failure.
• The Arc Monitor is installed by authorized personnel only.
• This manual is a part of the Arc Monitor and should always be accessible to
personnel working with this product.
• Read and understand the manual throughly before performing any installation
or commissioning.
• Excessive amounts of dust on the optical detectors can lead to a degradation
of detection. When regular inspections are made, it is recommended also to
inspect the detectors. Clean with dry cloth if needed.
• CSU is constantly sending light to the CSU input at the Arc Monitor during
normal conditions (for safety and reliability reasons). The light might decrease
over time and should be checked every year by a manual diagnostic test. See
more information in chapter Maintenance and in HMI functions.
• A log is kept that indicates if the light level had decreased below a certain level.
If so, the CSU should be replaced within the next 6 months.
• The safety of the system will not be affected if the CSU is not replaced. How-
ever, when the light level becomes too low then the Arc Monitor will recognize
this as a high current situation. And then the system functions as if there was
a no current condition, that is, trip on light at optical detectors only.
• Configuration is done with DIP switches, settings of parameters and control-
ling of configuration is done in the HMI.

Safety

Storage Storage in original package requires a temperature range of between, -25C°
to +70C° (-13F to + 158F) and a humidity maximum 95%.
Limitation of
liability
The safety information in this manual must not be considered as a guarantee
from ABB that the equipment cannot cause accidents or injury, even if all the
safety instructions have been observed.

Arc Monitor functions
17
1: Arc Monitor The Arc Monitor is the heart in the system and handles signalling and detec-
tion. The HMI handles conditions, errors, and more. The system can be con-
figured to trip selected breakers, depending on which sensor detects light.
The DIP-switches that take care of this function also handle settings like
auto-reset and Current Sensing Units. Energy is stored in the Arc Monitor for
operation up to 0.2 s if the supply voltage fails. This is sufficient to close the
tripping contacts even during a short time of power loss.
2: Human Machine
Interface, HMI
The Human Machine Interface is used for all communication with the user
and also to confirm any changes. It can be mounted both on the product and
on the cabinet door. This is preferred to be able to get information about trips
without opening the cabinet after a trip.The HMI has a non-erasable memory
which holds trip logs and error logs even after power loss including a time
stamp.
The Arc Monitor can handle a second HMI module.

4: DIP switch The DIP switch is a physical switch on the Arc Monitors front.
DIP switches are used to activate the CSU, auto reset and assigning trip
contacts.
5: Detector Inputs Detector inputs are used to connect the detectors to the Arc Monitor.
6: Current Sensing
Unit input
The Current Sensing Unit (CSU) is an accessory needed only in those few
specific applications where strong light is expected on a regular basis. Cur-
rent Sensing Units are connected with an optical fibre using light as signal for
normal current. If the connection is removed by accident, the system ignores
the CSU and will react only on an arc flash.
Note!
DIP Switch 1 or/and 2 must be configured if the CSU is in use.
To read more about the CSU configuration; See the chapter “One (1) CSU
connected” on page - 44
7: Current Sensing
Unit output
This output is used to pass the CSU signal forward to another Arc Monitor.
8: External HMI
connection
HMI can be mounted separately or a second module can be connected
(option).
Note!
Only use the included three meter (118 inch) cable for communication.
To learn more about the HMI functions; See the chapter “Human Machine
Interface, functions” on page - 61.
