Plan replacement or redesign of defined safety-relay functions around the actual machine, defined safety functions, device list, drawings and stopping behaviour, line connections, operating limits, acceptance checks and next steps.
For replacement or redesign of defined safety-relay functions, start with the actual machine, defined safety functions, device list, drawings and stopping behaviour and your full operating sequence, then check fault, mode, reset, restart, diagnostics and foreseeable intervention scenarios before committing to a final layout.
Plan a safety relay upgrade around the required safety functions, device inputs, safe outputs, reset and restart behaviour, diagnostics, wiring changes and validation evidence.
Plan a safety relay upgrade around the required safety functions, device inputs, safe outputs, reset and restart behaviour, diagnostics, wiring changes and validation evidence. For replacement or redesign of defined safety-relay functions, the deciding details include required safety functions and safe states, relay architecture, monitoring and reset configuration and wiring drawings, settings and validation evidence.

For replacement or redesign of defined safety-relay functions, describe the current position, required outcome, acceptable limits and known exceptions for required safety functions and safe states. That lets us compare options against your real production rather than one nominal value.
For replacement or redesign of defined safety-relay functions, describe the current position, required outcome, acceptable limits and known exceptions for device inputs, zones and operating modes. That lets us compare options against your real production rather than one nominal value.

For replacement or redesign of defined safety-relay functions, include normal operation, setup, access, faults, reset, restart and maintenance. The selected device is only one part of the complete safety function.
Verify the intended response for required safety functions and safe states in each relevant operating and access mode.
Introduce agreed faults affecting device inputs, zones and operating modes and confirm the safe response and diagnostics.
Prove that reset, restart and recovery behave as specified, then retain wiring drawings, settings and validation evidence.
Compare with Migration From Obsolete Relays to Supportable Configurable Safety Control if that operating pattern is closer to your application.
