Operating manual VISATRON® Oil Mist Detector VN2020 / VN2020 EX
Part number 183001 Version 3.0
4.3.2 Device variants
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.
The VISATRON
®
VN2020 / VN2020 EX oil mist detector from Schaller Automation can
be used as follows:
• Non-Ex version of the device; only approved for operation outside of potentially
explosive atmospheres
• EX version of the device; approved for operating inside potentially explosive
atmospheres
Explosion of the crankcase, for dual-fuel or gas engines
There is a risk of serious injury, including death, from explosion in the crankcase as a
result of incorrect assembly or installation.
The oil mist detector is designed to draw in gases from a potentially explosive
atmosphere (for example, the crankcase of a gas engine). The device without
ATEX or IECEx approval must therefore never be used in potentially explosive
atmospheres.
4.3.3 Bracket
The bracket is used to hold the oil mist detector and to connect the oil mist detector to
the engine housing.
When designing the installation kits, this bracket is adapted to the engine geometry or
designed for the applicable application, for each customer.
