- Dépannage & Guide d'entretien
5.1 Common Fault Analysis
| Phénomène de défaut | Causes possibles | Inspection Steps |
| Coil fails to pull in | 1. Insufficient or reversed coil voltage | 1. Measure coil voltage to confirm 24V DC |
| 2. Bobine brûlée | 2. Tester la résistance de la bobine (normale: approx 480Ω) | |
| 3. Câblage lâche | 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 collé | 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. Panne du circuit interne |
5.2 Entretien & Replacement Suggestion
- Safety Priority: Cut off power and wait at least 5 minutes for capacitor discharge before maintenance.
- Structure modulaire: On-site repair is not recommended; integral replacement is preferred.
- Procédure de remplacement
Record wiring positions by photos or sketches
Remove old module from DIN rail
Install new module and reconnect wires accordingly
Power on and verify normal operation
- Preventive Maintenance
Inspect terminal connection every 6 mois
Avoid overload, réserve 30% current margin
Shorten replacement cycle to 2-3 years under harsh conditions
