If the cause of the error is a defect in the integrated flame scanner,
the red and green LED’s will blink alternately.
Pressing the reset button on the front panel of the D-LX 100 acknowledges a fault in the unit and
allows flame scanning functions to continue after restart. When the reset button is pressed, all LEDs
will go off. It is also possible to reset the unit by open the plug connection or by interrupting the yellow
24 V supply wire for a short moment. In this case the cover of the flame scanner don’t has to be
opened in order to get access to the reset button.
If the power supply is interrupted or the reset button is pressed, the relays are released, regardless of
the status of the unit (flame signal ON / OFF or fault). The flame scanning program is then restarted.
Note:
The D-LX 100 is an officially approved flame scanner. Any tampering or modifications will lead to a
loss of its approved status. Repairs may only be performed by the manufacturer or its authorized
service outlets.
