2.1 Intended use
In line with its identification, this micropulse transducer is
suitable as electrical equipment for use in gas and dust
explosive areas. When installed in a machine or system,
the transducer forms a position measuring system in
conjunction with a controller or evaluation unit and may
only be used for this purpose.
When selecting the electrical equipment, the person
setting up the machine or system is responsible for
assessing its suitability for the planned area of application.
The information in the user’s guide and other applicable
safety regulations and provisions must be observed during
set-up. Flawless function is ensured only when using
original BALLUFF accessories. Use of any other
components will void the warranty.
The operator of the machine or system must ensure that
the transducer is applied under the permissible operating
conditions in line with the information in this user’s guide
and in compliance with the applicable safety regulations
and provisions.
Unauthorized interventions, non-permissible use, or
application outside the permissible operating conditions
will result in the loss of warranty and liability claims against
the manufacturer.
2.2 Safety measures
The persons setting up and operating the machine or
system must take steps to ensure that a malfunction in the
transducer will not result in hazards to persons or
equipment. If there are any indications of damage or
malfunctions, the transducer must be immediately taken
out of operation and secured against unauthorized use.
Even with correct explosion protection, residual risks
remain that could pose a hazard to persons and systems
when the device is correctly operated or if there are any
fault states.
