- Depanare & Ghid de întreținere
5.1 Common Fault Analysis
| Fenomen de eroare | Cauze posibile | Inspection Steps |
| Coil fails to pull in | 1. Insufficient or reversed coil voltage | 1. Measure coil voltage to confirm 24V DC |
| 2. Colac ars | 2. Test coil resistance (normal: approx 480Ω) | |
| 3. Cabluri slăbite | 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 | |
| Lipirea contactului | 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 |
5.2 Întreţinere & Sugestie de înlocuire
- Safety Priority: Cut off power and wait at least 5 minutes for capacitor discharge before maintenance.
- Modular Structure: On-site repair is not recommended; integral replacement is preferred.
