General Overview: The document discusses the implementation of safety functions in machinery using programmable electronic control systems. It emphasizes the importance of ensuring that these systems meet performance requirements to maintain safety, referencing standards like IEC 61508, ISO 13849-1, and IEC 62061.
Hardware Aspects: Hardware components such as sensors, actuators, and logic solvers must be selected and designed to meet safety function requirements. This includes architectural constraints, appropriate equipment selection, and measures to avoid systematic failures.
Software Aspects: Software must be designed to meet safety performance specifications. Application software should not be reprogrammable by users unless access is restricted to authorized personnel.
Manual Control Principles: Manual control devices should be ergonomically designed and located to ensure safety. Stop controls should be near start controls, and controls should be out of danger zones unless necessary. Operators should have a clear view of the working area.
Control Modes for Maintenance: Specific control modes should be used during maintenance to ensure operator safety. These modes should disable other controls, allow operation only under reduced risk conditions, and prevent unintended hazardous operations.
Selection of Control Modes: Machinery with multiple control modes should have a lockable mode selector to ensure only one mode is active at a time, restricting certain functions to specific operators.

Limiting Hazard Exposure: Mechanization and automation of loading/unloading operations reduce operator exposure to hazards. Maintenance points should be located outside danger zones to minimize access needs.
Safeguarding Measures: Guards and protective devices should be used when inherent safety design measures are insufficient. Selection of safeguards should be based on risk assessment and the nature of moving parts.
Overview: This document outlines safety measures and requirements for machinery operation, focusing on the use of guards and protective devices to prevent access to hazard zones during normal operation, maintenance, and other tasks. It emphasizes the importance of selecting appropriate safeguards based on the frequency of access required and the specific hazards present.
1. Fixed and Movable Guards: Fixed guards are recommended where operator access to danger zones is not needed during normal operation. When frequent access is required, alternative protective measures such as movable interlocking guards or sensitive protective equipment should be used. A combination of safeguards may be necessary to address multiple hazards.
2. Sensitive Protective Equipment: Various types of sensitive protective equipment, including light curtains, laser scanners, and pressure-sensitive mats, are discussed. These devices are used for tripping, presence sensing, or both, and must be selected based on the specific application and machinery characteristics.
3. Access Requirements: Different safeguards are recommended based on whether access to the hazard zone is required during normal operation, machine setting, maintenance, or other tasks. Interlocking guards, sensitive protective equipment, and two-hand control devices are among the options.
4. Design Considerations: The design of guards and protective devices should consider ergonomic principles, visibility, and environmental conditions. They must be robust, not introduce additional hazards, and be difficult to bypass.
5. Stability and Other Protective Measures: Stability should be maintained through design or protective measures like anchorage bolts and movement limiters. Additional devices may be required to limit movement parameters, prevent collisions, and ensure safe operation.
6. Implementation and Monitoring: Sensitive protective equipment must be integrated with the machine's control system to ensure safety commands are maintained until a new command is given. The document also outlines conditions for cycle initiation using sensitive protective equipment.
Adjustable Guards Requirements
Adjustable guards are permissible only when the hazard zone cannot be fully enclosed for operational reasons. They must be designed to remain fixed during operations and be adjustable without tools.
