Von Duprin SL4110XHFS MaxHold Electromagnetic Lock

The Von Duprin SL4110XHFS MaxHold Electromagnetic Lock is a high‑strength industrial magnetic latch that uses a 24 V DC power supply and an integrated control board to energize the electromagnet. Common failure modes in this series include coil burnout or insulation degradation, controller IC faults, and degraded power‑supply conditioning due to age or vibration. First‑check diagnostics: verify the 24 V input voltage and continuity of the coil leads; inspect the control board for burnt components or loose solder joints; review any error codes from an attached access‑control module and confirm that the lock’s status LEDs are functioning correctly.[oss-gpt-20b]
