Replace or Realign the Bridge Stowed Limit Switch

Safety Warning: Before proceeding, ensure the simulator is in a zero-energy state and follow all facility-specific Lock-Out/Tag-Out (LOTO) procedures to prevent unexpected motion platform activation.

1. Access the drawbridge hinge and stowed position area to locate the physical limit switch.
2. Inspect the switch mounting bracket for signs of loose hardware or misalignment; if misaligned, adjust the bracket so the bridge actuator arm consistently depresses the switch plunger when in the fully raised position.
3. If the switch is dirty or obstructed by debris, clean the housing and the actuator contact surface using an electronics-safe contact cleaner and a lint-free cloth.
4. If the switch fails to toggle state during a manual test with a multimeter, remove the mounting screws and disconnect the wiring harness, then install a new, manufacturer-specified limit switch.
5. Reconnect the wiring harness and verify the state change using the simulator's Motion Diagnostic Screen; the status bit should transition from 'False' to 'True' when the bridge is manually pushed into the stowed position.
6. Clear all tools from the area and perform a system power-up to confirm the bridge successfully raises upon motion initiation.
