ABB ARC GUARD SYSTEM™ – T VOC-2 INSTALL ATION AND MAINTENANCE GUIDE
2.4 Work in safety manner
Safe working methods must be used to prevent injuries.
The safety equipment must not be disengaged, bypassed
or in any other way modified so that the safety effect
ceases.
2.4.1 Handling the Arc Monitor
The Arc Monitor may only be used for the purposes
mentioned in this manual. 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 thoroughly 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. However, 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 controlling of configuration is done
in the HMI.
2.4.2 Storage
Storage in original package requires a temperature range
of between, -25C° to +70C° (-13F to + 158F) and a humidity
maximum 95%.
2.4.3 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.
