Gas Burner Safety Control DKG 972

For 2-stage atmospheric gas burners

Flame detection:

— Ionisation probe

— Infrared-flicker detector IRD 1020.1

— UV flame sensor UVD 971

INTRODUCTION

The burner control box DKG 972 controls and supervises

atmospheric burners for gas. They are approved and certified

according to the applicable European standards and

regulations.

The microprocessor-based programming sequence ensu-

res extremely stable timings independent of voltage varia-

tions, ambient temperature and/or switch-on cycles. The

built-in information system not only provides a continuous

monitoring of the actual state of the box (very helpful es-

pecially for monitoring the start-up phase) but also informs

about the cause of a possible lock out. The lock out cause

is stored in such a way that it can be retrieved even after a

power failure.

The control box is designed for maximum safety in case of

fluctuations in the voltage supply. If the mains voltage drops

below the permitted level, operation is interrupted and the

control box automatically prevents the start sequence from

being repeated. In this way, the safety of the system is not

put at risk by a drop in the mains voltage. This low-voltage

protection works not only during start-up but also perma-

nently during operation.

CONSTRUCTIONAL FEATURES

The control box circuitry is protected by a flame resistant,

transparent plug-in type plastic housing. A central fixing

screw locks the control box to the wiring base.

The plug-in control box incorporates the microprocessor

based timer, flame check and reset circuits.

Manual reset from lock out and set to lock out is provided by

a push button with an integrated LED information system.

A variety of cable entry points provides complete flexibility

for electrical wiring.

The wiring base S98 is equipped with spare- and extraterminals

and allows together with a variety of cable entry points utmost

flexibility of electrical wiring.

The DKG 972 are compatible with the TFI 812.

Different are only the pre- and post-ignition times.

Max. heating power according the limits in the Gas Appliance
