1.7 Commissioning
notes
When commissioning the plant for the first time or when doing maintenance work, make
the following safety checks:
Safety check to be carried out
Expected response
Delivery state (factory setting):
a)
Burner startup with previously
interrupted line to the flame detector
Non-alterable lockout at the end of the
safety time (TSA)
b)
Burner operation with simulated loss
of flame. For that purpose, cut off the
fuel supply
Non-alterable lockout
↑
Max. 3 repetitions
(can be parameterized)
c)
Burner operation with flame detector
exposed to extraneous light
Non-alterable lockout after approx. 30
seconds
Table 1: Safety checks
After installation and commissioning, of a plant, the parameterized values and settings
must be
documented
by the person/heating engineer responsible for the plant. These
data can be printed out with the help of the PC software ACS410, for example, or must
be written down. The documentation must be checked by the expert and then kept in a
safe place.
Warning!
On the OEM access level of the LMO39…, it is possible to make parameter
settings that differ from application standards. When setting the parameters, it
must be made certain that the application will run safely in accordance with
legal requirements.
Particular requirements in line with EN 298: 2012 must be taken into
consideration for applications involving stationary air heaters (WLE).
Example: Maximum safety time (TSA) = 5 seconds
If this is not observed, there is a risk of loss of safety functions.
Prior to commissioning, the following points must be checked:
∂
The correct time parameter settings, especially the settings of the safety and
prepurge times
∂
The correct functioning of the flame detector in the event of loss of flame
during operation (including the response time); with extraneous light during the
prepurge time and when there is no establishment of flame at the end of the
safety time
