Figure 144 Detector Assembly
The oil mist detection chamber in each Detector Head must be inspected at regular intervals and cleaned
to remove any build-up of oil splash or carbon deposits created by the operation of the engine.
The OMD system will automatically warn the Users when the detection optics become partially obscured
and must be cleaned. Establishing a cleaning and maintenance regime to minimise any Fault message
warnings of this type and maximise the service life of each Detector Head is recommended, see section
4.3.
WARNING - Do NOT remove the Detector from the base whilst the engine is in operation.
This action should be carried out whilst the engine is stopped to avoid the possibility of hot oil
coming out of the Detector Base.
Please Note
Graviner Detector Heads should only be cleaned with the recommended cleaning fluid and cleaning buds.
Many cleaning fluids have been evaluated by Graviner but only the Electrolube ASC fluid is recommended
by Graviner as our tests have shown it offers the best cleaning ability and leaves no residue on the glass
chamber.

Note: - Do not use any third-party electronic contact cleaners, isopropyl alcohols, flux removers, any
harsh chemical cleaners, etc., as these will affect the Detector performance.
Only use the official Graviner Cleaning products, see 6.4.2.
