If you ever feel unsafe when riding in an elevator, know that modern elevators include a wide range of features to minimize the risk of accidents. The elevator safety circuit ensures that all necessary components of the elevator are operational before running. If any safety systems are malfunctioning, the circuit will break, removing power to the drive and engaging the brakes in turn.
Learn the components of an elevator safety circuit, how it works, and how elevator monitoring services can further enhance the security of your passengers.
What Is an Elevator Safety Circuit System?
An elevator safety circuit is a series-connected electrical loop that acts as a fail-safe monitoring system to prevent accidents. All of the switches in the circuit must be closed for the safety relay to be energized, which allows the elevator to run.
The safety circuit usually consists of each of these switches:
- Speed limit switch: Speed governors constantly monitor the speed of the elevator to stop the car if it exceeds its rated speed. The speed limit switch opens when the elevator reaches an unsafe speed, interrupting the elevator safety circuit and stopping the system.
- Emergency stop switches: Emergency stops are located in the pit, on the top of the car, and on the controller. When any of these stops are not working, the emergency stop switch will not close, preventing the elevator from running.
- Door interlock switch: The elevator system should automatically lock the door before the elevator can start moving. If the safety circuit detects that the door is not locked, the elevator will not run until it detects that it is.
How Elevator Safety Circuits Work
When elevator safety components are working as normal, the switches in the safety circuit stay closed or “healthy,” keeping the safety relay energized and allowing the elevator to run as normal. But if any device fails or the switch is activated, the electrical circuit breaks, cutting power to the drive and applying the brakes.
Modern elevators often use LEDs to identify which part of the safety string is open, allowing technicians to quickly pinpoint the malfunction.
Anyone who has researched elevator safety tips knows that malfunctions are rare in modern systems. However, the elevator safety circuit presents an added layer of protection to give both passengers and building owners peace of mind.
