Warnings issued when several consecutive malfunctions occur that lead to an interlocking of the AKAS@
with displayed error reports. The interlocking status can be cancelled only by a voltage reset.

complete switch-over of the slow speed posi-
tion monitors into slow speed. Check the SGA
line for interruptions and check also the slow
speed position monitors and their lines.

This error happens only during the operating
mode "for connection to safety PLC" if the
signals at the SGO and the SGS are not
exactly the same.
The key switch ot the front reset switch have been ac-

an error within the foot pedal, or the front reset button
does not close.

internal error
I f this message is displayed immediately after
a voltage reset, there is an EMC problem or an
internal failure of the appliance.
