6.2 Programa de mantenimiento & Guidelines
Inspección diaria: Visually check for contact ablation, loose wiring and abnormal noise
Monthly Maintenance: Limpiar la superficie del núcleo, inspect contact wear
Quarterly Maintenance: Medir la resistencia de la bobina, retighten all terminal screws
Annual Maintenance: Replace worn contacts, test insulation performance, verify pull-in and drop-out voltage
6.3 Quick Diagnosis Tips
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.
