Abstract:
An elevator system (20) includes a sensor (30, 36) for detecting the presence of an individual within a hoistway (24). A controller (32) prevents movement of an elevator car (22) whenever an individual is in the hoistway (24). A pit override device (34) provides an override signal to the controller (32) permitting movement of the elevator car (22) if someone is in a pit (26). A car top override device (38) selectively provides an override signal to the controller (32) permitting movement of the car. A disclosed example includes controlling at least one light (40) within the hoistway (24) in conjunction with movement or attempted movement of the elevator car (22).
