Why Elevators Shut Down, Fault, and Fail
Today’s elevators are part of a much larger electronic network often connected to building management, life safety, access control, and security systems. These systems include highly sensitive electronics such as VFDs, PLCs, door controllers, network communication lines, safety relays, and control boards. These sensitive electronics are vulnerable and, if damaged or operating with improper power, can affect the functionality of equipment they are connected to throughout the entire system in the facility.
Elevator shutdowns are most often caused by nuisance tripping, control faults, and safety shutdowns triggered by minor electrical disturbances on the power and control circuits rather than mechanical problems. This is why a common solution to recurring elevator problems involves installing surge protection devices (SPDs).
TPD surge protection not only protects your elevator from surges and lightning, but when applied correctly, leads to less nuisance tripping, fewer service calls, longer control board life, and significantly improved elevator reliability. To keep elevators working, TPD is your one-stop solution!
How do I install SPDs to protect my elevator? We can help! Protecting your elevator starts with protecting the sensitive electronics connected to the elevator. This is done by placing surge protection at the panelboard or disconnect that feeds the elevator, and at the elevator’s individual control circuits where sensitive electronics are most vulnerable.
- For a 120/208 volt system, use the TPX-3Y208-F-100 at the panelboard or disconnect.
- For a 277/480 volt system, use the TPX-3Y480-F-100 at the panelboard or disconnect.
- For each individual control circuit, use one TK-LT120-20A.
