After a non-alterable lockout, the red signal lamp (LED) lights up.
In that condition, the visual diagnostics of the cause of fault according to the error code
table can be activated by pressing the lockout reset button for more than 3 seconds.
Pressing the reset button again for at least 3 seconds, the interface diagnostics will be
activated. Interface diagnostics works only if the AGK20... lockout reset button
extension is not fitted. If, by accident, interface diagnostics has been activated, in which
case the slightly red light of the signal lamp flickers, it can be deactivated by pressing
again the lockout reset button for at least 3 seconds. The instant of switching over is
indicated by a yellow light pulse.
