2Critical Safety Information

2.1 Proper Use of the Sentinel Guarding System

The Sentinel 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 Sentinel 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 Sentinel 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 Sentinel system has been installed.

•The Sentinel 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 Sentinel 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 Sentinel 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

Sentinel 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 Sentinel Press Brake Guarding System protects until the

laser sensors are 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 Sentinel

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 Sentinel

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 Sentinel system can be used only on hydraulic press brakes or machines deemed by

relevant regulatory authorities to have equivalent functional and dynamic characteristics.
