8.1 Maintenance Tasks
NOTICE
The flame scanner requires no maintenance
However, you should at intervals – that depend on the operating conditions of the plant – clean
the aperture of the compact flame scanner and the associated viewing opening on the fur-
nace.
NOTICE
If it is necessary to clean the optics of fiber optic flame detectors, special care should be taken
to clean the fiber optic surface. Damage to the surface can result in significant signal loss.
During periodic maintenance of the plant, you should do the following things:
• Check all the electrical plug-in connections.
• Put the burner into operation.
• Check that the flame scanner is in working order.
• Check the response time when the flame goes out.
► Does it switch off correctly?
• Create a log of the measurements and checks carried out. If necessary, have this signed.
