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.

EDM does not respond
even though the OSSDs
are released
If this happens during fast speed: valve position mo-
nitors do not switch in fast speed position or at an in-
terruption in the EDMS circuit.
If this happens during Muting: EDMS and EDMO
are both at + 24 V
with additional sa-
fety PLC
(e.g.
FPSC}
When switching over from fast speed into slow
speed, at SGO remains+ 24 V
When switching over fast speed into slow speed,
the triggereing of the SGS and the SGO is antiva-
lent instead of equivalent
machine stops at the over-
run traverse cam/ cam
switch does not conduct
in the case of "warning": open press completely, in
the case of "error": check cable and cam switch

This message is displayed when the stroke is star-
ted in slow speed range or with a slow speed re-
quest SGA = 0 and if there is no complete switch-
over of the slow speed position monitors into slow
speed. Check the SGA line for Short circuit to +24 V
and check also the slow speed position monitors and
their lines.

repeats itself, a repair by Fiessler Elektronik is ne-
cessary.

The transmitter is triggered although the foot pedal is
released, or a transmitter from another AKASĀ® fo-
cuses the receiver. This must be prevented by ade-
quate constructional measures.

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 activated when the foot pedal was pressed,
or there is an error within the foot pedal, or the
front reset button does not close.
If this message is displayed immediately after a vol-
tage reset, there is an EMC problem or an internal
failure of the appliance.
