Standards & Procedures Framework for SPM Operation

A. Key International Standards for SPMs

Standard	Scope
ISO 12100	Risk assessment and reduction principles.
ISO 13849-1/-2	Safety-related control systems—design and validation.
IEC 60204-1	Electrical safety and control panel specifications.
ISO 13850	Emergency stop function requirements.
ISO 14120	Guarding design and mounting.
ANSI B11 Series	U.S. machine safety standards (risk, guarding, operator interface).
NFPA 79	North American standard for electrical systems in industrial machinery.

B. Pre-Operation Procedures

• Operator Verification: Confirm training certifications.
• Daily Checks: Test E-stops, guards, interlocks, sensors, and air/hydraulic systems.
• Risk Review: Confirm no recent changes to tooling/process affecting hazard profile.

C. Production Start-Up

• Warm-Up: Run dry-cycle to test all axes and sensors.
• Calibration: Validate force, torque, or vision systems.
• Cycle Start: Use two-hand/foot-pedal/HMI; observe first run in “jog” mode.
• Monitoring: Use MES or HMI to track OEE, cycle time, reject rate, and alarms.

D. Shutdown & Post-Operation

• Safe Stop: Controlled stop via HMI—not abrupt shutdown.
• Cleaning: Remove debris; lubricate moving parts.
• Tooling Reset: Home all axes; LOTO for fixture changes.
• Log Entry: Record any issues or wear points in the machine log.

E. Maintenance & Safety Validation

• Routine Maintenance: Follow OEM-prescribed tasks weekly/monthly.
• Safety Validation (ISO 13849-2): Semi-annual test of E-stops, guards, interlocks.
• Change Management: Reassess risks post tooling/electrical/software modifications.
• Annual Review: Use incident/downtime logs to drive continuous improvement.

F. Emergency Handling

• E-Stop Activation: Investigate cause; reset only after resolution.
• Faults: Use HMI diagnostics; log error codes; escalate if unresolved.
• Incident Reporting: Log every unplanned stop or near-miss; apply root-cause analysis.
