Working Principle
Three independent processor channels within the T3120 simultaneously execute the same safety application logic. Each channel reads inputs, performs calculations, and generates outputs independently. A hardware voter compares the three output sets and forwards the majority result to the system output modules. If one processor channel fails, the voter detects the discrepancy and continues system operation using the remaining two healthy channels.
Installation Requirements
- Install in the designated processor slot of the T3100 chassis
- Connect redundant power supplies within the specified voltage range
- Ensure proper chassis grounding before powering the system
- Verify all three processor channels synchronize correctly during startup
- Maintain environmental conditions within specified temperature and humidity ranges
Operating Precautions
- Monitor processor status LEDs for fault indication
- Maintain all three processor channels for full TMR redundancy
- Replace failed processor modules promptly to restore fault tolerance
- Perform regular proof testing to verify TMR voting integrity
- Back up application programs before performing maintenance
- Follow electrostatic discharge procedures when handling modules
