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.
Particular attention must be paid to such instructions.
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.

The setting must be done in a way that the following test will be passed:
!!! If either test A or B fails, the machine must not be used until the problem is resolved !!!
- The B-Test must be done for safety reasons each 5 times on the left end and on the right end of
the upper tool.
- The press brake must be equipped completely with the heaviest upper tool.
- Start of the closing movement from the maximum top dead centre (T.D.C)
At the beginning of each shift and after each change of tools, the AKAS® press brakes protection
must be checked as follows (see also EN 12622):
Test must be carried out at both left and right ends of the bending punch.The punch must not touch the
step-shaped test rod.
a.) Place the test piece in position "10" on the lower tool. Select the box bending function if you use a
system of the AKAS®3... product family. Now start the close down movement.
b.) The press brake stops.
c.) The test piece must be placed in position "15" under the upper tool. In this position ("15") the test
piece may not touch the upper tool.
d.) Drive up the press brake. Place the the test piece in position "35" on the lower tool. Select the
normal bending function if you use a system of the AKAS®3... product family.
Now start the close down movement.
e.) The press brake must be stopped in a way
that the test piece ("35") may not touch the
upper tool.
f.) Turn on the sender ( adjustment keyswitch
to ON position )and move the test piece ("14")
along
the tip of the upper tool. The adjustment
controll LED P1 on the AKAS® receiver
has to remain ON during the test.

1. Use only tools with the same height in the same fixing on the press. All utilized tools must have one common
bending line.
2. Stoppers, which are mounted at the matrix, lead to a premature switching-off of the downward
movement.
3. The maximum allowable overrun traverse of the machine:
15mm / AKAS®-LC..., 14mm / AKAS®-II.., 13mm / AKAS®-3... .The press must have an automated
overrun traverse control for the first stroke. If not, it can be realised by the AKAS®-...F and a cam controller or
by the Fiessler AMS-system . Before the initial start-up, the overrun traverse must be checked either by using
the test rod (see page 9) or by using an Overrun Traverse measuring device. (upon customer's request, Fiessler
Elektronik will perform the Overrun Traverse Measuring on the customer's machine.) If one results of 10 consecutive measu-
rements is larger than 15mm / AKAS®-LC... , 14mm / AKAS®-II... i.e. 13mm / AKAS®-3... , the fast speed must
be reduced.
4. Due to the missing sychronization during fast speed, AKAS® cannot be used for two machines aligned in
parallel (e.g. "tandem press brake") .
5. Muting signal If a light beam is interrupted by the sheet which is to be bent, the AKAS® would stop the working
stroke immediately. Therefore the AKAS® must be muted before it gets interrupted by the sheet. Likewise, slightly
uneven sheets should not lead either to an unintended switching-off of the cutting movement. From an opening of <
23 mm (AKAS®-I, -LC) resp. from an opening corresponding to the recommended change over point (see page 19)
from fast speed to work speed (AKAS®-II... and AKAS®-3...) the control system of the machine must send a Mu-
tingsignal to the reciever.. Then the control system of the machine must reliably guarantee according to safety
category 4, that from this time the stroke speed is < 10 mm/s.
6. The protection of a pressbrake by the AKAS® does not permit bending in the bottom of a box inside the box
in fast speed.
7. The AKAS® does not protect: -if the machine is only run in the work speed, or AKAS will be
interrupted during fast speed and the stroke will be continued in
work speed
-if the overrun traverse of the press brake is too long
-from squeezing during the bending operation
-if the mutinglamp is constantly on
8. The hazardous state of the machine must be terminated by the sensor function.
9. The safety level (class 4) of the accident preventing light barrier should at least correspond to the safety le-
vel of the control system of the machine.
10. Laser beams may be deviated due to air currents, this may cause unwanted and unforeseen machine
stops. Therefore the machine must be erected at a place free of air currents.

request, Fiessler Elektronik will perform the initial acceptance as well as the annual test. Additionally, customer
training seminars on how to execute annual tests will be conducted at regular intervals.
The machine owner must make sure that a competent person is assigned to check the light barrier annually. This
person can be an employee either from the light-barrier manufacturer or from the operator's staff. The annual test
shall be executed according to the inspection sheet on pae 53.

suspension devices with electromotor driven
supports:
the System AKAS®-3 automatically adjusts on-
to the required distance to the bending punch
after a tool change.
The laser - accident preventing light barrier AKAS® is an electro sensitive protective and controlling device
(ESPE) which has the function to protect operators from accidents.
This happens as follows : Before a part of the body is squeezed between two opposed moving machine parts,
this part of the body interrupts at least one light beam. By this means the movement of the machine is stopped,
before it comes to an injury.
AKAS®
- meets IEC 61496, Type 4
- is self- monitoring without additionally wiring.
- easy to adjust after tool changing.
Operative range for the laser-accident preventing light barrier of the AKAS® types are: press brakes
AKAS®-3M /-3F, AKAS®-IIM /-IIF: equipped with electromotor driven supports for transmitter and receiver for
self-acting tool change if tools with diefferent heights are used (see fig. 11/1).
AKAS®-LCM /-LCF: is recommended if there are no freqent tool changes or in case if extended operation with
the same tool is required, therefore no re-adjusting to different tool sizes is necessary. (see fig. 11/2).
suspension devices with mechanical adjust-
ments:
if there are no freqent tool changes or in case
if extended operation with the same tool is

1. Release the closing movement by activating the foot pedal.
2. Press brake closes in fast speed (> 10mm/s)
3. After reaching the change-over point from fast speed to slow speed (= 10 mm/s):
4. All receiver elements are muted and the muting lamp is on. The bending procedure is finished.
(The fast speed mode and the slow speed mode are limited of about 2 min.)
The beams of the AKAS® must be located at a certain distance to the bending punch.
(See chapter 5.2 Overrun Traverse Measurement and
chapter 5.8 Adjustment of the distance between the AKAS® and the bending punch.
Caution! Use only tools with equal overall height within one fixing.
Closing movement with interrupted protective field
The AKAS® system offers the possibility to execute a closing movement under monitored slow speed even when
the protective field is interrupted by a wavy sheet metal.
After the interruption of the protecfive field and the release and reactivation of the foot pedal, the AKAS will deacti-
vate the SGA output when the protective field is interrupted. By this, only slow speed will be enabled by the machi-
ne control (NC).
AKAS® provides a reaction time of about 200ms for the machine control and then activated the safety switching
outputs for the closing movement (OSSDs). The OSSDs remain activated as long as the AKAS® receives a
slow speed message to SGS and SGO within the next 70 ms + the selected enhanced tolerance. A tolderance en-
hancement is possible only with the AKAS® .....F systems.
By twice pressing the foot pedal can also use this function to perform a stroke, when the protective field
of the AKAS ® is interrupted in the OT.

1. "Box Bending" is activated by the box bending button. The signal at the box bending input KAST must be high
(+24V) for at least 100 ms and after that low (0V) for at least 100 ms.
(The box bending function can be canceled by twice activating the box bending button again)
2. AKAS® confirms the selection of the box bending by activating the output HUSP and the LED box-bending
3. Release the closing movement by activating the foot pedal. The press closes in fast speed (> 10mm/s).
4. After reaching the change-over point from fast speed to slow speed (= 10 mm/s) :
5. All Receiver elements are muted and the muting lamp is on. The bending procedure is finished.
(The fast speed mode and the slow speed mode are limited of about 2 min.)
6. After the bending procedure the box bending functiuon is cancelled.
Closing movement with interrupted protective field
The AKAS® system offers the possibility to execute a closing movement under monitored slow speed even when
the protective field is interrupted.
After the interruption of the protecfive field and the release and reactivation of the foot pedal, the AKAS will deac-
tivate the SGA output when the protective field is interrupted. By this, only slow speed will be enabled by the ma-
chine control (NC).
AKAS® provides a reaction time of about 200ms for the machine control and then activated the safety switching
outputs for the closing movement (OSSDs). The OSSDs remain activated as long as the AKAS® receives a
slow speed message to SGS and SGO within the next 70 ms + the selected enhanced tolerance. A tolderance en-
hancement is possible only with the AKAS® .....F systems .
In the case of bending of very small pieces, which must be guided by the fingers, the box-bending function
must be selected. Otherwise, the fingers would interrupt E1 (AKAS ® -IIM/-F and AKAS -LCM/-LCF ®), or
E3, E4, E5, E6 (AKAS -3M/-F ®), which would lead to the switching off of the bending process !
With activated box-bending function, a finger which is placed next to the slog on a large matrix, is not
detected!!

The press must have an automated overrun traverse control for the first stroke. If not, it can be realised by
the AKAS®-...F and a cam controller or by the Fiessler AMS-system . Before the initial start-up, the overrun tra-
verse must be checked either by using the test rod (see page 9) or by using an Overrun Traverse measuring
device. (upon customer's request, Fiessler Elektronik will perform the Overrun Traverse Measuring on the customer's machine.)
If the results of 10 consecutive measurements are larger than 15mm (AKAS®-LC...), 14mm (AKAS®-II...) bzw.
13mm (AKAS®-3...) , the fast speed must be reduced.
According to the induvidual overrun traverses of each machine, 8 different distances Z (=gap betrween uppermost receiver ele-
ment and bending punch, see Fig. 19/1 u. Fig. 19/2) can be programmed via 3 dis switches at the support. The adjustment to the re-
spective selected distance is carried out automatically. (s. chapter 5.7 (Adjustment of the distance of the AKAS® from
the bending punch). Fiessler delivers the system pre-adjusted "A".

- 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 re-
ceiver 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
exaclty to the bending line. The receiver elements E5 (AKAS®3 fig. 20/3) and E1 (AKAS®-IIM fig. 20/2) must
face the operator and E1 (AKAS®3 fig. 20/3) respectively E2 (AKAS®-IIM fig. 20/2) must remain free when the
highest tool is utilized. (Fig. 20/ 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. Fig. 20/ 5
