RESIDENTIAL GAS BURNERS
R D BR D B seriesR D BR D B seriesControl 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 sequenceIf the operating voltage drops below the undervoltage threshold, a restart will be made with the full program sequenceIf there is a premature faulty flame signalLockoutIf the contact of the air pressure monitor «LP» has welded in the working position, start up will be preventedand, after 65 seconds, lockout initiatedIf the contact of the air pressure monitor «LP» has welded in the idle position: lockoutat after 52.5 secondsIf the burner does not ignite by the end of safety time LockoutIf 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 3seconds!

Burners TRAining CEntre
Error code table A
Blink code Possible cause
2 x No establishment of flame at the end of «TSA»– Faulty or soiled detector electrode
– Faulty or soiled fuel valves– Poor adjustment of burner
3 x Air pressure monitor does not close– «LP» faulty
– «LP» incorrectly adjusted – Fan motor does not run
4 x Air pressure monitor does not open or extraneous light on burner startup
– «LP» faulty– «LP» incorrectly adjusted
5 x Extraneous light during pre-purging– Or internal device fault
7 x Loss of flame during operation– Poor adjustment of burner
– Faulty or soiled fuel valves – Short-circuit between detector electrode and ground
8...17 x ; Free
