The lockout reset button (EK) is the key operating element for resetting
the burner control and for activating / deactivating the diagnostics
functions.
The multicolor signal lamp (LED) in the lockout reset button is the key
indicating element for both visual diagnostics and interface diagnostics.
Both elements (EK / LED) are located under the transparent cover of the lockout
reset button.
There are 2 diagnostics options:
1. Visual diagnostics: Operational status indication or diagnostics of the cause of
error.
2. Interface diagnostics: With the help of interface adapter OCI400 and PC software
ACS410 (in preparation).
A description of the visual diagnostics is provided below.

flashing warning signal. Press the lockout reset button (EK) for 10 seconds again to
