Figure 5: Interface schematic
The device can be connected directly to the engine
’s safety system. The interface contains
two oil mist alarm outputs, a pre-alarm output and a Ready signal.
During normal operation, the crankcase atmosphere is drawn in simultaneously at all suction
points and tested in the measuring head.
There are two alarm thresholds. The main alarm threshold can be parameterised using
software via the USB interface in the measuring head.
The pre-alarm can also be parameterised. Using the factory setting, it is activated at 70% of
the main alarm threshold.
The two device types, VN2020 and VN2020 EX, can be purchased separately as oil mist
detectors or as a complete oil mist detection system (installation kit).
