3.3 Life Cycle
The device is designed to have a service life of 10 years or 250,000 cycles. The functional
safety calculations are based on these values.
The actual service life of the F300K depends on the ambient temperature among other factors.
In particular, operation at high temperatures reduces the actual service life.
3.4 Proper Use - Conditions of Use
The F300K is designed to monitor the safety of burner flames in single- and multi-burner com-
bustion plants and in combustion chambers for dust- and grate-fired systems.
As an explosion-proof device, the flame scanner can be used in potentially explosive atmos-
pheres (up to Zone 2).
Any other usage going beyond this is considered to be improper use. The plant operating com-
pany is liable for any damages that resulting from this.
The table in Section 3.6 Selection Criteriashows the applications to which the various device
types are suited.
