This publication outlines the application of functional safety principles to CENTERLINE Low Voltage Motor Control Centers (LVMCC), specifically for Bulletin Numbers 2100 and 2500. It serves as a guide for integrating various safety-related products to enhance operational safety and productivity.
Key Features and Benefits
The document details standardized implementations that can lead to:
- Minimized delivery times for safety-equipped LVMCC units.
- Reduced overall acquisition costs.
- Maximized operational safety and productivity through the selection of appropriate motor controller units as safety function subsystems.
- Minimized personal and enterprise risk in engineering safety functions.
Scope and Content
This application technique covers both CENTERLINE 2100 and CENTERLINE 2500 LVMCCs. It includes descriptions, electrical schematics, and configuration information for various safety subsystems, such as:
- Motor controller units (with hardwired and integrated safety options)
- Safety control relay distribution units
- Safety monitoring relay distribution units
- Bulletin 1734 safety I/O remote distribution units
The focus is on common safety functions like emergency-stop (E-stop) mechanisms, detailing how safety relays, contactors, and Variable Frequency Drives (VFDs) are integrated. The document also addresses the calculation of performance levels (PL) and provides verification and validation checklists for example applications.
Safety Standards and Risk Assessment
Emphasis is placed on adhering to relevant safety standards, including EN ISO 13848-1, EN 62061, IEC 61508, and ISO 12100. The importance of performing thorough risk assessments to identify and address hazards is highlighted, with guidance on safety distance calculations and considerations for stopping performance.
Note: Users are responsible for system safety considerations, including sensor/actuator validation, system-level risk assessment, certification, and proper programming and configuration.
