The transmitter generates two or three modulated visible laser light beams.
WARNING:
The AKAS
®
does not
protect,
- if the machine runs only in work speed, i.e. no more than 10mm/s ( 20mm/s USA Version)
- if the machine runs in workspeed (no more than 10mm/s), ( 20mm/s USA Version)
- if the overrun traverse of the machine comes to more than 10mm
- if the pressbrake works only in a single speed.
- if more than one machine is monitored by one single AKAS
®
system e.g. tandem pressbrakes.
Use the AKAS
®
only on one machine.
WARNING: The front beams which is turned to the operator does not protect, if the
case-bending function has been activated earlier.
WARNING:
With activated function of case-bending the finger is not detected as shown in picture
S4/2 !
The protection of a pressbrake by the AKAS
®
does not permit a bending in the bottom of a case inside
one case in fast motion.
On pressbrakes equipped with AKAS
®
protection only tools of equal height may be used in one fixing.
All tools fixed together may have only one common bending line.
Stoppers, which are mounted at the matrix, lead to a premature switching-off of the downward movement.
The pressbrake safety system AKAS
®
can only be used when the following requirements are fullfilled:
The machine or system can be electronically controlled and it must be possible to stop the hazardous motion at any ti-
me.
The pressbrake safety system AKAS
®
is a special safety systems only for hydraulik pressbrakes.
See also chapter 2.1 "Prerequisites for using the Pressbrakes protection AKAS
®
"
Muting contact: free of potential, may be closed only at a lifting speed / working speed ≤ 10 mm/s.
It must comply with safety category 4 according EN 954.
The overrun traverse including the safety equipment must be less than 13 mm.
The pressbrake is equiped with an automatique overruncontrol for the first stroke after bringing the machine under
tension.
The part of control system of the machine which is responsible for the stopp of the machine must full fil the require-
ments of category 4 according EN 954.
Both muting signals must be connected by separate cables in order to exclude any short circuit, or the layout of
cables must be effected in a way that no mechanical damage of the cable may occur, thus excluding any short
circuit of the lead of the cable.
To use the pressbrake safety system AKAS
®
the following requirements must be met:
— The guarded press brake must be able to stop anywhere in its cycle. Do not use a pressbrake safety system
AKAS
®
on a press with a full-revolution clutch.
— The guarded machine must not present a hazard from flying parts.
— The guarded machine must have a consistent stopping time and adequate control mechanisms.
— Severe smoke, particulate matter and corrosives may degrade the efficiency of the pressbrake safety system
AKAS
®
. Do not use the the pressbrake safety system AKAS
®
in this type of environment.
