This is the operating instruction for the AKAS® models AKAS®-3M, AKAS®-3F,
AKAS®-IIM
AKAS®-IIF and AKAS®-LCM, AKAS®-LCF. Special instructions for each model are provided
with its individual model marking.
Attention is drawn to all safety instructions by this symbol.

These operating instructions provide to the user important information concerning the correct use of the AKAS®.
These instructions are a component of the light barrier concerned. It is essential that they are easily available at
the location where the safety light barrier is installed. Before the initial operation of the AKAS®, all requirements
detailed in these operating instructions must be observed. Other relevant regulations and the requirements of
the employers' liability insurance associations have also to be complied with.
Mounting, initial operation and maintenance may only be performed by qualified persons.
Light barriers do not protect anybody from machine-caused flying objects.
The AKAS® protects fingers and hands that hold the sheet during the operation.
Therefore it does not protect
during any fast engagement between the bending punch and the matrix short time before those are
closed. The protection function of the system is cancelled when the Muting lamp is on.
The front beams E3-E6 (
AKAS®-3M, AKAS®-3F)
, i.e. E1 (
AKAS®-LCM, AKAS®-LCF, AKAS®-IIM,
AKAS®-IIF)
which are turned to the operator before the bending line do not protect, if the box-bending
function has been activated earlier.
With the integration of a AKAS ® safety system, the standard should be strictly complied with the
European Standard (EN 12622).
Protection circuits and Emergency can only stop the opening movement when the movement is
interupted with the RXOK outputs.
