Von Duprin MaxHold Electromagnetic Lock

Von Duprin MaxHold Electromagnetic Lock DS4010 is a high‑strength, no‑moving‑part locking device used in industrial access control. Common failure modes for this class include power supply degradation (voltage drop or intermittent supply), coil heating and insulation breakdown, and contact corrosion on the magnetic armature. First‑check steps: verify 24 V DC input voltage and continuity of the lock coil; inspect the armature for visible damage or excessive wear; review any error codes from the control panel or indicator LEDs for power or fault status.[oss-gpt-20b]
