Elevator door and motion interlock logic

This elevator door and motion interlock diagram turns a few basic operating conditions into two outputs. RUNENABLE requires a car call, closed and locked doors, no overload, normal inspection status, and a condition away from a floor. DOOROPENENABLE allows an opening command only when the car is at a floor and the same inhibit conditions are clear.

図の背後にある意思決定を読み解く。

01

Both closed and locked door signals are required for movement.

02

Overload and inspection mode inhibit normal operation.

03

An at-floor signal prevents a normal run command.

04

Door opening requires the car to be at a floor and not overloaded.

Use this for a digital logic or controls exercise. Actual elevator safety chains use redundant, monitored, safety-rated circuits beyond this conceptual gate diagram.

よくある質問

よくある質問

Why need both door closed and locked?

They represent distinct conditions; a closed door is not necessarily mechanically locked.

What does inspection mode do?

It inhibits normal automatic motion in this simplified model.

Is overload normally a gate input?

An overload condition commonly prevents normal operation, though implementation is equipment-specific.
