Terms

The press brake protection AKAS® is an electrosensitive protective device (ESPE).
ESPE is characterised by the fact that a hazardous motion becomes interrupted or prevented if the 

light beams

produced between the transmitter and receiver unit  are interrupted.

AKAS ® meets Safety Category 4 according to EN 954, e PL (Performance Level) according to EN ISO
13849-1: 2008 and SIL 3 according to EN 62061:2005 Devices to safety category 4, PL e, SIL 3 are self-
monitoring sensitive protective equipment and provide the highest Safety class among the sensitive
protective equipment.

The electrosensitive protective device (ESPE) switches automatically into the "safe state" when it is faulty.

Maximum distance between transmitter and receiver is 8 m.
(For longer range please get in contact with Fiessler Elektronik or your local dealer).

The maximum upper tool length is 6m.
(For longer range please get in contact with Fiessler Elektronik or your local dealer).

The part of the hazardous motion still taking place after interrupting the light beam.

The distance covered during the overrun (e.g. by the ram of a press).

The duration of the overrun  traverse.

The time that elapsed after light beam interruption until the switching action occurs.

Before every release of the output contacts the contactor control is checking whether the switching elements connec-
ted (relays, contactors or valves) have been released. A renewed release of the 
output contacts is only possible  if  the switching elements connected have been released. Thus a dangerous failure of
switching-elements (relays, contactors or valves) caused by the hazardous motion is prevented.

After initial operation or after a power supply interruption a renewed "enabling" is blocked by the start interlock.The re-
newed  release of the switching unit  is only possible by closing and opening  of the start entry.

The restart interlock prevents any automatic releasing of the switching outputs after an interruption and 
re-enabling of the light beam (e.g. when penetrating the light beam).

Short-time safe by-pass of the press brake protection AKAS® during material movement, i.e. during a plate bending
process.

Selected receiver elements will be muted, all other receiver elements stay active.

By-pass of the receiver unit E3-E6 (AKAS®-3PM, AKAS®-3PF), during a box-bending process. 

Muting of the receiver elements E3 – E6 (AKAS®-3PM, AKAS®-3PF) during a boxbending stroke.
This is required because the side panels of the box will interrupt E3 – E6
