Burners TRAining CEntre RESIDENTIAL GAS BURNERS R D B R D B series Control program in the event of fault:  If a fault occurs, all outputs will immediately be deactivated (< 1 s)  On restoration of power, a restart will be made with the full program sequence  If the operating voltage drops below the undervoltage threshold, a restart will be made with the full program sequence  If there is a premature faulty flame signal  Lockout  If the contact of the air pressure monitor «LP» has welded in the working position, start up will be prevented and, after 65 seconds, lockout initiated  If the contact of the air pressure monitor «LP» has welded in the idle position: lockout at after 52.5 seconds  If the burner does not ignite by the end of safety time  Lockout  If flame is lost during operation:  Three repetitions Lockout:  Lockout cannot be changed and takes place 10 seconds after safety shutdown. A main voltage failure during that period of time wil lead to a restart. Resetting:  When never lockout occurs, the burner control can immediately be reset. To do this, keep the lockout reset button depressed for a minimum of 0.5 seconds and a maximum of 3 seconds!
