LMO24 fault-diagnosis and operation
The burner release button "EK" is used to reset the burner unit and to turn the fault-
diagnosis functions on and off.
The multicoloured LED is used for both types of fault diagnosis.
The "EK" button and the LED are located under the transparent cap of the release
button.
Two types of fault diagnosis can be used.
1 Visual fault diagnosis - The burner's operating status or the cause of the fault is
displayed.
2 Interface fault diagnosis - Using the OCI400 interface and the ACS400 software or a fume analyzer.
Visual Fault Diagnosis
During normal operation, the various operating statuses are shown by the colour combinations as shown
in the table below.
Interface fault diagnosis is activated by pressing the burner release button for at least 3 seconds. If this
mode gets turned on accidentally, a weak red light starts blinking; to go back to the normal mode, just
press the Reset button again for at least 3 seconds.
The passage from one mode to the other is shown by the yellow LED blinking.
