9.3 Lockout
If a lockout condition occurs, the combustion manager initiates a fault shutdown
and burner lockout.
The display and operating unit alternately shows the shutdown behaviour and the
fault diagnosed as a plain text display.
Once the fault has been rectified, the combustion manager has to be reset for re-
start.
