Behaviour During Operation; Restart - Honeywell Krom Schroder BCU 580 Technical Information

Parameters

10 .4 Behaviour during operation

10 .4 .1 Restart

Parameter 09
This parameter determines whether the BCU initiates
an immediate safety shut-down with fault lock-out or
an automatic restart after a flame failure during opera-
tion. Excessive restarts (max. 5) can also be detected.
In accordance with EN 746-2, a restart may be con-
ducted only if the safety of the installation is not im-
paired. A restart is recommended for burners which oc-
casionally display unstable behaviour during operation.
The precondition for an automatic restart is that the
burner can restart (as intended in all operating phases).
In this case, it must be ensured that the program se-
quence started by the BCU matches the application.
