- トラブルシューティング & メンテナンスガイド
5.1 Common Fault Analysis
| 故障現象 | 考えられる原因 | Inspection Steps |
| Coil fails to pull in | 1. Insufficient or reversed coil voltage | 1. Measure coil voltage to confirm 24V DC |
| 2. コイル焼け | 2. Test coil resistance (普通: approx 480Ω) | |
| 3. 配線の緩み | 3. Check terminal tightness | |
| No contact movement | 1. Jammed forced guided mechanism | 1. Check mechanical flexibility after power off |
| 2. Oxidized or burnt contacts | 2. Inspect contact surface damage | |
| 3. Mechanical wear | 3. Verify contact travel distance | |
| Contact sticking | 1. Arc burn caused by overload or short circuit | 1. Check actual load exceeding rating |
| 2. Contact material fatigue | 2. Replace relay module | |
| LED indicator off | 1. Damaged LED | 1. Check power supply connection |
| 2. Power disconnection | 2. Replace with identical module for test | |
| 3. Internal circuit failure |
