Example for connection

Atmospheric burner with ignition gas output. After the heat request and an adjustable delay, the ignition is switched on and V1 and Vz are opened. After the fl ame has been detected, the main gas fl ow V2 is opened. Fan burner, direct ignition of the main gas fl ame. After the heat request, the fan is switched on, and the air pressure is checked by the pressure switch. After the pre-aeration time has lapsed, the ignition is switched on, and the two valves V1 and V2 are opened together.

The program sequence and times can be modifi ed on the mounted display (MPA 4112/MPA 4122) to match each application. A laptop or PC is not required for the modifi cation. The automatic burners are protected by passwords against unauthorised access.
