Fiessler AKAS-3PF Operating Instructions Manual Download Page 16

- The dimensions of the self-supplied holders must be individually laid out according to the dimensions
of the press brake. 
- The self-supplied holders must be made of torsion-free rigid material, e.g.  steel tubes 80 x 50 x 5 mm.
- They must be sufficiently long so that the largest and the shortest tool are still within the detection

 range of the AKAS® .

- If frequent tool change requires the presence of a swivable holder,  this should be installed at the recei-
ver arm, in order to leave the  precise adjustment  of the transmitter arm unchanged. 

a) The holders must be mounted at the ram in a way that the marks on transmitter and receiver correspond exacl-
ty to the bending line. The receiver elements E5 (AKAS®3 fig. 20/3) must face the operator and E1 (AKAS®3 fig.
20/3) must remain free when the highest tool is utilized. 

(Fig. 16/ 2 u. /3)

d) The lowest edge of both supports must be at the same level. 
c) The gap between the front edge of the AKAS®systems  and the press brake should be   > 100mm in order to
prevent injuriers while closing the press.
d) The existing mechanical guards of the  machine must be modified in a way that any by-passing of the safety
equipment by the operator is not possible. Likewise, any danger of geeting caught between grids and safety
equipment must be excluded.

Transmitter and receiver of the AKAS® must  not be subject to mechanical stress (e.g. bottles  must not
be placed on it). To prevent this and to protect the AKAS®  from any damages, a solid protection cap
should be always mounted.
Make sure that no material or solid parts are placed in the clearance beneath the AKAS® and the holders,
in order to exclude  any collision caused by the closing movement of the press
brake.
