Page 6: Safety Signs Instruction
Please take note of the contents marked includes the peroper operation instructions, taken as the important components for SLA-3 device, ensure of the manual placed at right place. 2. Operator Ability To carry out the installtion,adjustment and maintenance by the qualified person 3. -
Page 7: Application Guide
2. The SLA-3 is not used to monitor two bending machines placed in a horizontal plane 3. If the workpiece block the light beams, SLA-3 stop immediately... - Page 8 4. SLA-3 special mode enables the bending or wavy material or even edge bending within a closed box. If the bending machine only closes at work speed,or too big excess of stroke, SLA-3 won't provide protection, i.e. won't prevent access to the hazardous area.

Page 9: Terminology
State of an item characterized by inability to perform a required function, excluding the inability during preventive maintenance or other planned actions, or due to lack of external resources. Performance Level(PL e): SLA-3 device comply with EN ISO 13849 PL e requirements,i.e. EN954 cat.4 requirements. -
Page 10: Usage
The E3 is muted during during bending process. 2.2 Usage SLA-3 is the safety device specially applied to bending machine for operator's protection which adpoted class 1 laser, A three-dimension laser protective field between the emitter and receiver to form the guarding area underneath the clamped upper tool, any intervention into the area shuts down the closing movement of the press. -
