Detailed Answer
Shipyard E-stop requirements: 1. Response <100ms (LDER LD series); 2. Independent hard-wired loop; 3. Signal-loss protection (stop within 1 second); 4. Daily pre-shift test; 5. Two-person confirmation for high-altitude/dock work. Shipyards are noisy, so E-stop tests need visual confirmation (light/alarm).
