Need robust safety in your machine or process? A GuardLogix CompactLogix PLd safety system using the 5069 controller can integrate safety devices like E-Stop pushbuttons, PowerFlex 525 VFDs, 100S-C motor starters, and Guardmaster light curtains to meet ISO 13849-1 PLd and TÜV SIL 3 standards. This certified approach minimizes risks while enabling efficient motion control. Here’s how to set it up in five steps.
The 5069 Compact GuardLogix achieves PLd through dual-channel diagnostics and CIP Safety over EtherNet/IP. It supports safe torque-off (STO) for drives, contactor monitoring, and presence sensing, reducing fault times to under 1.0 E-06 PFHd. This keeps employees and equipment safer during operations and emergency conditions.
Wire E-Stop Pushbuttons: Connect dual-channel E-Stops (e.g., 800T series) to 5069-IB8S safety inputs on Compact 5000 I/O. Use pulse-tested channels for fault detection; program with DCST instruction in Studio 5000 for Cat 3 monitoring.
Configure PowerFlex 525 VFD STO: Link STO terminals to 5069-OBV8S safety outputs via dual redundant wiring. Enable STO in drive parameters and use CROUT instruction to de-energize on demand, achieving immediate Stop Category 0.
Incorporate 100S-C Motor Starters: Wire 100S-C safety contactors auxiliary contacts to safety inputs for feedback. Program ESTOP logic to drop out coils on faults, ensuring redundant power removal.
Add Light Curtains: Integrate Guardmaster 450L series via CIP Safety to the GuardLogix. Wire OSSD outputs to 5069-IB8S inputs; configure for presence sensing with DCST for beam interruption detection.
Program and Verify Safety Task: In Studio 5000, create a safety task with reset routines (OSF for manual reset). Use SISTEMA tool to validate PLd, then test per TÜV guidelines for certification.
