Fiessler AKAS-3PM - Status Messages and Error Reporting

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 accepted that fullfill the following conditions: an even parity, successful reception of the mes-
sage is provided if it is received at least 3 consecutive times and if its complete compatibility to one of the mes-
sage 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.

Before the SP input is activated the receiver element E2 re-
spectively E4 must be interrupted by the Fiessler magnet pla-
te. Set the SP output of your machine to a corresponding
value.

open the press completely. If this message is repeated at the
following new stroke and the internal muting lamp does not
light up,there is an internal error at the version that has no
connection option of an external muting lamp. With the ver-

lamp, the connection KAST must be checked for short-circuits

-
possible reasoin: the protective field is interrupted, or the pro-
tective circuit is interrupted, or the foot pedal is released, or
no fast speed during the overrun traverse measurement, evtl.
because the stroke for the oberrun 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.
