- Dépannage & Entretien
6.1 Défauts courants & Solutions
| Phénomène de défaut | Causes possibles | Étapes de dépannage |
| Coil fails to pull in | 1. Insufficient coil voltage | 1. Mesurer la tension de la bobine, ensure it is within ±10% of rated value |
| 2. Bobine brûlée | 2. Tester la résistance de la bobine (normal value: several hundred ohms) | |
| 3. Open circuit in control loop | 3. Check fuses, pushbuttons and wiring of control circuit | |
| Soudage par contact | 1. Surcharge / court-circuit | 1. Check load current and replace damaged contacts |
| 2. Usure des contacts | 2. Replace contact assembly | |
| 3. Excessive operating frequency | 3. Reduce operation frequency or use higher-rated contactor | |
| Bruit anormal pendant le fonctionnement | 1. Dirty core surface | 1. Surface du noyau propre (power off first) |
| 2. Anneau d'ombrage cassé | 2. Replace shading ring | |
| 3. Printemps fatigué | 3. Inspect and replace spring assembly | |
| Serpentin surchauffé | 1. Excessive supply voltage | 1. Adjust voltage to rated value |
| 2. Température ambiante excessive | 2. Improve ventilation or apply derating | |
| 3. Aged coil insulation | 3. Replace coil | |
| Contacter l'ablation | 1. Courant de charge excessif | 1. Check load and select properly sized contactor |
| 2. Poor arc suppression | 2. Installer un limiteur de surtension | |
| 3. Defective contact material | 3. Replace original contact assembly |
6.2 Calendrier d'entretien & Guidelines
Inspection quotidienne: Visually check for contact ablation, loose wiring and abnormal noise
Monthly Maintenance: Surface du noyau propre, inspect contact wear
Quarterly Maintenance: Mesurer la résistance de la bobine, retighten all terminal screws
Entretien annuel: Replace worn contacts, test insulation performance, verify pull-in and drop-out voltage
6.3 Conseils de diagnostic rapide
Check power first if coil won’t act; test resistance when voltage is normal.
Check overload for welded contacts; clean core and inspect shading ring for noise.
Improve ventilation and derate for overheating; replace parts and suppress arc for ablated contacts.
- Sélection & Directives d'installation
7.1 Three-step Selection Procedure
- Confirm load type (AC-1 / AC-3) and rated current
- Select pole number and contact configuration (008 = 4P 2NO+2NC)
- Faire correspondre la tension de la bobine (B7 / G7 / M7, etc.)
7.2 Notes d'installation
Reserve clearance ≥50mm for heat dissipation; avoid vertical stacking installation
Installer un limiteur de surtension (RC circuit or varistor) on control circuit
Ensure reliable mechanical interlock when used with thermal overload relays
Maintain spacing ≥20mm between adjacent contactors
7.3 Conformité du transport aérien
Pas de batterie au lithium intégrée, compliant with air transportation safety regulations
CE certification number: Refer to product nameplate; conforme à la norme CEI 60947-4-1
