7 .16 Two-stage burner control with two 

solenoid valves

 

The IFD is equipped with two signalling contacts for 

operating and fault signals. For controlling two-stage 
burners, a bridge must be installed in the lower section of the 
housing between terminals 12 and 13. Valve V2 is connected 
to terminal 14.

 

gas valve V1 and ignites the burner. The ignition time t

Z

 is 

constant. The safety time t

SA

 starts with the igni-

 

tion time t

Z

. If a flame is detected during the safety time, the 

operation signalling contact closes and valve 2 is opened once 
the safety time t

SA

 has elapsed.

 

If no flame is detected, the fault signalling contact clos- es 
once the safety time t

SA

 has elapsed.

 

Example  of application

 

Control: ON/OFF or ON/HIGH/LOW/OFF

 

The burner BIO/BIC starts at low-fire rate. Once the normal 

operating state is reached, the automatic burn- er control unit 
IFD 258 opens the air valve. The burner switches to high-fire 
operation.

During the waiting time t

 after heat demand, checks are 

made for flame simulation and fail-safe operation. If no flame 
simulation is detected, the IFD 258 opens the
