产品介绍

DKO974/976 - Oil Burner Safety Control

For 1- or 2-stage oil burners up to 30 kg/h throughput and intermittent operations with or without oil preheating

Flame detection:

- Photoresistor MZ 770 S

- Infrared-flicker detector IRD 1010

- UV flame sensor sensor UVD 970

he microprocessor- based programming sequence ensures extremely stable timings independent of voltage variations, 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 especially 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 permanently during operation.
