2 – Architectural principle and standards of <strong>Safety</strong> <strong>Manager</strong><br />
- De-energizes upon a safety related fault in Control Processor 2 or an<br />
output module of Control Processor 2.<br />
- When de-energized, Control Processor 2 and the related outputs are halted.<br />
• WD3<br />
This is the <strong>com</strong>bined watchdog line, controlled by both Control Processors.<br />
- De-energizes upon a safety related fault in a non redundant output.<br />
- When de-energized, the non-redundant outputs are de-energized, but the<br />
redundant outputs and the Control Processors remain operational.<br />
