Critical Safety Information
2.1
Proper Use of the Defender Guarding System
The Defender Press Brake Guarding System is designed to protect hands and fingers in the
area close to the edge of the punch. When installed correctly and safety instructions are
observed fully, the Defender system permits safe manipulation close to the punch, as well as
offering effective protection while tools close at high speed. Please note these general safety
notices:
•
The Defender system is designed exclusively for installation and operation on
hydraulic press brakes, or press brakes that comply with the statutory machine safety
and accident prevention rules and regulations valid for the place where the press
brake is operated, in particular after the Defender system has been installed.
•
The Defender system must be installed either in the press brake factory, or by
specialist technicians trained by Lazer Safe (or its authorised representatives).
•
The operator must be fully conversant with the operation of the press brake and the
risks associated with it, as well as the operation of the Defender Press Brake
Guarding System.
•
The alignment of the protective equipment for punches of different lengths should be
performed by a die setter (or someone with equivalent specialist expertise) trained in
all relevant aspects of operating the press brake and the Defender Press Brake
Guarding System.
•
Suitable protective equipment must be worn by the operator at all times.
2.2
Special Warnings
To ensure the highest possible degree of safety in operating a press brake fitted with the
Defender Press Brake Guarding System, it is important to note the following special warnings.
Warning: AVOID FAST, ERRATIC MOVEMENTS AS TOOLS CLOSE.
When the tools close at high speed (above the mute point) towards a static (fixed)
obstruction, there will be less than maximum protection at the point where the
laser detects the obstruction. For example, if a small obstruction such as a finger
is rapidly and erratically pushed between the punch and an obstruction,
immediately before the laser senses the static obstruction the finger might be
touched.
Warning: NO PROTECTION BETWEEN MUTE POINT AND WORKPIECE.
In Normal mode, the Defender Press Brake Guarding System protects until the
laser is within 2mm of the material surface. Even though this gap is too small for
a finger to be inserted,
always exercise care
.
Warning: NO OPTICAL PROTECTION IN FIELD MUTED MODE
In Field Muted mode, all optical guarding is deactivated. Although the Defender
Press Brake Guarding System ensures that the machine does not exceed safe
speed in this mode, particular caution must still be exercised.
Entry to Field Muted mode can be password protected, and should only be
used by suitably trained personnel, and only in exceptional circumstances
(changing tools, maintenance, etc.).
Warning: NO OPTICAL PROTECTION IN TOOL SET-UP MODE
In Tool Set-up Mode, all optical guarding is deactivated. Although the Defender
Press Brake Guarding System ensures that the machine does not exceed safe
speed in this mode, particular caution must still be exercised.
2.3
Regulatory Requirements for Use
The Defender system can be used only on hydraulic press brakes or machines deemed by
relevant regulatory authorities to have equivalent functional and dynamic characteristics.
