Repair Steps: What to Do Before You Fix It

When an Industrial Control System fails, act quickly but systematically. Follow these detailed steps:

1. 1. Assess the Situation
   • Stop all operations immediately if safety is at risk
   • Follow proper lockout/tagout procedures
   • Document error messages and system behavior
   • Check if it's a system-wide failure or isolated issue
   • Take screenshots of HMI/SCADA displays if possible
2. 2. Troubleshoot Systematically
   • Review system logs and error history
   • Check network connectivity and communication
   • Verify power supply and I/O signals
   • Test sensor inputs and actuator outputs
   • Review recent program changes or updates
3. 3. Prepare Required Resources
   • Identify necessary replacement parts
   • Gather appropriate tools and testing equipment
   • Check inventory or contact suppliers for parts
   • Arrange for specialized equipment if needed
   • Ensure safety equipment is available
4. 4. Plan the Repair Process
   • Create a step-by-step repair procedure
   • Estimate repair time and production impact
   • Coordinate with production scheduling
   • Assign roles to maintenance team members
   • Set up contingency plans if needed
5. 5. Execute the Repair
   • Follow manufacturer's repair guidelines
   • Replace or repair damaged components
   • Check alignment and tensioning
   • Lubricate all necessary points
   • Document all work performed
6. 6. Test and Verify
   • Run system at low speed initially
   • Check for proper alignment and tracking
   • Listen for unusual noises
   • Monitor temperature of bearings and motors
   • Test all safety devices and controls
7. 7. Document and Follow Up
   • Record all repairs in maintenance log
   • Update maintenance schedule if needed
   • Brief operators on any operational changes
   • Schedule follow-up inspection
   • Review and update preventive maintenance plans
