Lamtec ETAMATIC S User Manual

9 Appendix
– Adjust setpoint value of the three-point step channel in the air deficiency direction (for
dead band setting, see parameters)
– Reset setpoint value to original value
– Run all channels this way in succession to the limit at the various firing rate points
– normally at low, medium and high fire
– Repeat this for all relevant operating modes (curve sets).
WARNING!
If applicable, perform the test which is described above in the air deficiency direction rather
than in excess air direction unless it is ensured that the flame is stable and there would be no
excess CO at the limits, which are set in the excess air direction.
9.25 Tolerance Limit in Direction Air Deficiency
To be able to perform the test, the parameter values in the air deficiency direction should be
known.
WARNING!
If the default setting for dead bands and monitoring bands have changed during commission-
ing, this must be documented clearly.
There is no tolerance in the air deficiency direction if the following parameter setting is re-
tained:
– For fuel channels and recirculation channels - dead band in positive direction
parameters 42 to 46 = 0 digits
– For air channels - dead band in negative direction
parameters 32 to 36 = 0 digits
Furthermore, the ’band shift in the event of output change’ (P 709 to P 712) must have the
same value as the monitoring band for the corresponding channel in the air deficiency direc-
tion (P 62 to P 76) so that there is no tolerance on the air deficiency side even when there are
firing rate changes.
If changes are made to this setting, a documented test of the combustion limit values must be
performed, as described previously.
WARNING!
If applicable, the correctness of these parameter settings must be verified. This may be done
by checking the parameters on the device or by checking the values via remote software or
another suitable analysis tool. We recommend the documentation be done in a form of a pro-
tocol. The protocols of the burner settings may contain such a protocol.
Note for the example of a protocol on the next side:
press key 12
press keys 2 and 3 to run to the firing rate point for checking it
wait until the system has run to that point
enter password
press key 14 one time (setting)
