4.4 Intended use
When used on large engines that have mandatory explosion protection classification, an
oil mist detector with corresponding ATEX or IECEx approval must be used in potentially
explosive atmospheres.
Section 3.1 Marking and type description
The task of the oil mist detector is to prevent explosions in the crankcase of large
engines caused by a high concentration of oil mist, such as can occur in the event of
bearing damage within a large engine.
The oil mist detector therefore must only be used for the detection of oil mist in
crankcases and to protect against oil mist explosions on large engines (diesel, gas and
dual fuel).
When used on large engines with mandatory approval by maritime classification
societies, an oil mist detector with corresponding class approval must be used.
The safety instructions are mandatory and must be observed!
Improper handling or other use of the device is considered to be use not as intended
and therefore constitutes an unapproved mode of operation. The manufacturer is not
liable for any resulting damage.
