The AKAS® displays messages by serial transfer via its RS 232 interface; transfer format: 9600 baud, 1 start
bit, 8 data bits, 1 stop bit. The messages have even parity and will be repeated at least three times. The time
gap between 2 messages is at least 100 ms. At the receiver, defective messages are gated, because only tho-
se messages are accpted that fulfil the following conditions: an even parity, successful reception of the message
is provided if it is received at least 3 consecutive times and if its complete compatibility to one of the message
possibilities indicated below is given.
There are different kinds of messages:
- Information concerning the status
of the AKAS® or
handling directions
for the operator,
here are Bit 0 and Bit 1 = 1,
-
Warnings
concerning errors that, if received three times one immediately after the other, may lead to the in-
terlocking of the AKAS®, here is Bit 0 = 0 and Bit 1 = 1,
-
Error reports
of the interlocked AKAS® , here is Bit 0 = 1 and Bit 1 = 0.

the version that has no connection option of an exter-
nal muting lamp. With the version with external con-
nection option of an external Muting lamp, the con-
nection KAST must be checked for short-circuits on -.

-
possible reasoin: the protective field is interrupted, or
the protective circuit is interrupted, or the foor pedal is
released, or no fast speed during the overrun traverse
measurement, evtl. because the stroke for the ober-
run traverse measurement has not been started by
the UDC of the machine. Open the press completely
and carry out a new stroke for the overrun traverse
measurement.
