Error
If the system detects a fault, it switches to the safety or lockout phase to run the burner
control to a safe state.
SAF
When in a certain error class, a change to the SAP phase is made, and all safety-
related outputs are deactivated. This way, lockout and a subsequent reset shall be
avoided. If, for example, undervoltage is detected, which might lead to erroneous
feedback signals, the system can go to this phase. When voltage returns to its normal
level, this phase can be quit again with no need for making a reset.
STOE
If a system error is detected that shall run the burner control to a safe state (lockout),
the unit goes to the lockout phase, which can only be quit again by making a reset.
