Safety Information

Ensure that this Operating Manual is read and understood BEFORE installing / operating /
maintaining the equipment. Pay particular attention to Warnings and Cautions. All document
Warnings are listed here and repeated where appropriate at the start of the relevant
chapter(s) of this Operating Manual. Cautions appear in the sections/sub-sections of the
document where they apply.

Strictly follow the Instructions for Use

Any use of the detectors requires full understanding and strict observation of these
instructions. The detector is only to be used for purposes specified here.
The cover on Detector must be kept tightly closed until power to the detector is isolated
otherwise ignition of a flammable atmosphere can occur. Before removing the cover for
maintenance or calibration purposes, ensure the surrounding atmosphere is free of
flammable gases or vapours.
Detectors must be protected from extreme vibration and direct sunlight in hot environments
as this may cause the temperature of the detector to rise above its specified limits and cause
premature failure.

Maintenance

It is recommended to obtain a service contract Prosense to carry out all repairs. Only
authentic Prosense spare parts must be used, substitute components may invalidate the
certification and warranty of the detector. Maintenance and calibration operations must only
be performed by qualified service personnel.

Use in areas subject to explosion hazards

Equipment or components which are used in potentially explosive atmospheres and have
been tested and approved according to international or European regulations may be used
only under the conditions specified here. Modifications of components or the use of faulty or
incomplete parts are not permitted. In case of repairs of equipment or components, the
national regulations must be observed.

Liability for proper function or damage

The liability for the proper function of the detector is irrevocably transferred to the owner or
operator to the extent that the detector is serviced or repaired by personnel not employed or
authorized by Prosense or if the sensing head is used in a manner not conforming to its
intended use. Prosense cannot be held responsible for damage caused by non-compliance
with the recommendations given above. The warranty and liability provisions of the terms of
