Honeywell DKG972-N Mod 28 220v Control Box 0432028

 

Application

The burner controllers DKG 972-N control and supervise 2 stage atmospheric burners. They are tested and approved according to EN298:2003. They can also be used with direct air heaters (DIN 4794).

 

Possible flame sensors:

• Ionization probe

• Infrared flame detector IRD 1020.1

 

Design and Function

The enclosure consists of a flame-resistant plug-in type plastic housing.

Microprocessor, electronic components, output relay, automatic flame guard are arranged on a printed circuit board. wellprotected in the housing.

The LEDs for the information system are located on the top of the housing.

 

Stable timings are achieved with the microprocessor-controlled program sequence, independent of:

• fluctuations of the line voltage

• ambient temperature

• starting cycles

The built-in visual information system not only permits continuous monitoring of the current events (useful especially to monitoring the starting process) but also provides information on causes of a possible lockout.

In each instance, the last error causes are stored in the device and can even be reconstructed after a voltage drop when the unit is switched on again.

The design of the burner controllers provides safety against low voltage conditions; thus the system is not endangered even in case of extreme voltage drops.
