9 Appendix
Adjust set-point value of the three-point step channel in the air deficiency direction (for dead
band setting, see parameters)

Reset set-point value to original value

Run all channels this way in succession to the limit at the various load points

- normally at low, medium and full load
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.
9.24 Tolerance Limit in Direction Air Deficiency
To be able to perform the test, you must know the parameter values in the air deficiency direc-
tion. The default setting for the relevant parameters is shown on the configuration label.
WARNING!
If the default setting for dead bands and monitoring bands have changed during commission-
ing you must document this clearly. Update the entries on the configuration label in a manner
that is durable and cannot be wiped off. (e.g. with a waterproof indelible felt-tipped pen.
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 shortage side even when there are
load changes. For deliveries made after 01.01.05, this will be the default setting and will be
marked on the device label.
If you have made changes to this setting, you must perform a documented test of the combus-
tion limit values, as described previously.
WARNING!
If applicable, you must clearly verify the correctness of these parameter settings. You may do
so by checking the parameters on the device or by checking the values via remote software
or another suitable analysis tool. We recommend that you note this in a protocol. 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 load point for checking it
wait until the system has run to that point
enter password
press key 14 one time (setting)
